The catalyst synthesis method-resulting molecular structure relationships, stability and reactive transformations of the active site in response to gas phase environment, reaction mechanisms, reaction intermediates, the corresponding kinetics and effect of some popular promoters are covered. Key structural features of the active sites have been extensively investigated but the conclusive structure is yet to be determined due to the diversity of the preparation methods (nature and crystallinity of the support, sulfate deposition method, sulfate coverage) as well as the diversity of the experimental conditions used during the spectroscopic determination. Similarly, the effect of the promoters and the synergistic effects of the promoter/sulfate sites in the presence of hydrocarbons are not well-defined. Finally, multiple theories exist for the reactive mechanisms on sulfated zirconia but most rely on the homogeneous reaction mechanisms, such as those for ethylene dimerization and butane alkylation with butane. Collectively, these show the lack of a fundamental understanding and the need of modern catalysis studies of this important catalytic system.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kiani, Daniyal</style></author><author><style face="normal" font="default" size="100%">Silva, Manoj</style></author><author><style face="normal" font="default" size="100%">Sheng, Yiying</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Experimental Insights into the Genesis and Growth of Struvite Particles on Low Solubility Dolomite Mineral Surfaces</style></title><secondary-title><style face="normal" font="default" size="100%">The Journal of Physical Chemistry CThe Journal of Physical Chemistry C</style></secondary-title><short-title><style face="normal" font="default" size="100%">J.

The effluent contains water, hydrogen and a diverse range of C2-C4 oxygenates: unconverted ethanol, n-butanol, acetaldehyde, ethyl acetate, and acetal. Fundamental phase equilibrium relationships suggested use of conventional, extractive, and heterogeneous azeotropic distillation units to perform the separations. All reactor effluent species exit the separation process at mole purities of at least 99%. Separation costs are estimated to range from 9.0 to 10.6 MJ/kg n-butanol, which is comparable with the separation costs of n-butanol obtained from established acetone-butanol-ethanol (ABE) separation process.

While sour natural gas is still treated using energy-intensive amine absorption/desorption, here we propose and describe a first step in catalytically producing a value added chemical and energy carrier, CH3SH and H2, respectively. For this purpose, we performed Density Functional Theory (DFT) and microkinetic modelling of CH4 and H2S reaction pathways to form CH3SH and H2 as a first step in elucidating complex yet not explored pathways in oxygen-free sour gas reforming. For this purpose, we utilized bare unpromoted and K- or Ni-promoted Mo6S8 clusters. CH4 dissociation was found to be the rate-determining step above 1100 K on Ni-promoted Mo6S8 while H2 formation was the rate-determining step on the bare and K-promoted Mo6S8. At lower reaction temperatures between 800 and 1100 K, CH3SH formation becomes an important step, especially on Ni-Mo6S8. This method presents an interesting route of direct catalytic sour natural gas processing which potentially leads to high-value hydrocarbons, such as ethylene, using CH3SH as a reactive intermediate.</style></abstract><issue><style face="normal" font="default" size="100%">16</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Johnson, Nicole</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author><author><style face="normal" font="default" size="100%">Luyben, William L.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Design and control of a cryogenic multi-stage compression refrigeration process</style></title><secondary-title><style face="normal" font="default" size="100%">Chemical Engineering Research and Design</style></secondary-title><short-title><style face="normal" font="default" size="100%">Chemical Engineering Research and Design</style></short-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Compression refrigeration</style></keyword><keyword><style  face="normal" font="default" size="100%">Compressor control</style></keyword><keyword><style  face="normal" font="default" size="100%">Multi-stage cycles</style></keyword><keyword><style  face="normal" font="default" size="100%">Refrigeration dynamic modeling</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2017</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2017/5//</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://www.sciencedirect.com/science/article/pii/S026387621730151X</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">121</style></volume><pages><style face="normal" font="default" size="100%">360 - 367</style></pages><isbn><style face="normal" font="default" size="100%">0263-8762</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">AbstractProviding refrigeration at very low cryogenic temperatures requires the use of several stages of compression refrigeration with progressively lower boiling point refrigerants in the various stages. The cascade of cycles ultimately rejects heat to cooling water, but the working fluid at each stage removes heat from a lower-temperature source and rejects this heat plus the compressor work in that stage to a higher-temperature sink. The design of these systems appears to be only qualitatively discussed in the literature, and no discussion of their plantwide dynamic control has been found.
This paper presents a quantitative design of a three-stage compression refrigeration process that uses methane, ethylene and propylene as the working refrigerant fluids in the three stages. Heat is removed in the condenser of a cryogenic distillation column separating carbon monoxide and methane. The bubble-point temperature of carbon monoxide at 13.9 bar is −158 °C. The distillation column condenser is cooled by evaporating boiling liquid methane at −163 °C. The second stage has an evaporator with boiling ethylene at −106.7 °C. The final stage has an evaporator with boiling propylene at −25.9 °C. An effective plantwide control structure is developed and tested.

Natural gas, however, can contain more than 10% sour gas molecules (chiefly CO2 and H2S), especially in the Middle East and Russia. Currently, the most common sour natural gas separation technologies rely on the use of various amine-based absorption-desorption cycles in absorption towers, membrane separation and cryogenic processes. However, these processes are quite expensive and, unfortunately, result in the necessity for further processing of the sour gas stream. We feel that the implementation of catalytic activation of the sour gas stream, so as to form useful products, has been underexplored and thus has yet to be fully developed. In this paper, we present a series of catalytic reactions for the sour gas components so as to obtain useful chemicals or fuels, such as carbon disulfide (CS2), hydrogen (H2), ethylene (C2H4), ammonium sulfate ((NH4)2SO4) and ammonium thiosulfate ((NH4)2S2O3). Particular catalytic reactions which can form those products are (a) CH4 reforming with H2S on supported metal oxide catalysts, (b) CO2 + H2S + H2 catalytic reaction on K2O/WO3/Al2O3 to yield a CH3SH intermediate, (c) olefin production via CH3SH coupling on zeolites and supported metal oxides and (d) H2S + NH3 catalytic reaction to yield ammonium sulfate ((NH4)2SO4) and ammonium thiosulfate ((NH4)2S2O3) on partial oxidation catalysts. Thermodynamic considerations, together with catalyst design techniques, are discussed for each reaction.</style></abstract><issue><style face="normal" font="default" size="100%">14</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kirinovic, Erica</style></author><author><style face="normal" font="default" size="100%">Leichtfuss, Amanda N</style></author><author><style face="normal" font="default" size="100%">Navizaga, Criztel</style></author><author><style face="normal" font="default" size="100%">Zhang, Hanyu</style></author><author><style face="normal" font="default" size="100%">Schuttlefield-Christus, Jennifer</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Spectroscopic and Microscopic Identification of the Reaction Products and Intermediates During the Struvite (MgNH4PO4·6H2O) Formation from Magnesium Oxide (MgO) and Magnesium Carbonate (MgCO3) Microparticles.</style></title><secondary-title><style face="normal" font="default" size="100%">ACS Sustainable Chemistry &amp; Engineering</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2017</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2017///</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">American Chemical Society</style></publisher><volume><style face="normal" font="default" size="100%">5</style></volume><pages><style face="normal" font="default" size="100%">1567–1577</style></pages><isbn><style face="normal" font="default" size="100%">2168-0485</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">One of the key global challenges forthcoming will be maintaining a clean, useable natural water supply.  Anthropogenic wastewater is an unavoidable result of population growth and societal development; therefore the treatment of wastewater is of the utmost importance.  The mineral struvite (magnesium ammonium phosphate hexahydrate, MgNH4PO4·6H2O) is a cryst. material that occurs naturally in decompg. org. materials and been obsd. in sludge derived from the anaerobic digestion of animal farming liq. wastes and treated wastewater sludge.  The accumulation of struvite on pipe walls and equipment surfaces has plagued the wastewater treatment industry though the formation of struvite prior to the treatment process could potentially provide a pathway for the sustainable recovery of the major nutrients nitrogen (N) and phosphorus (P).  Current methods of nutrient removal from wastewater are mostly based on insol. Fe, Al and Ca salt formation followed by landfill disposal without returning them to the environment.  Struvite is one of the most promising chem. platforms for recovering nutrients, which previously was done using expensive water-sol. magnesium salts.  Our objectives were to examine the potential of low soly., naturally abundant magnesium inorg. materials (MgO and MgCO3) for the utilization of nutrient recovery from wastewater via time resolved ex situ XRD, ATR-FTIR and Raman analyses, and SEM measurements to identify reactive intermediates and use spectroscopic data for kinetics anal.  Our data suggest that a common reactive intermediate between homo- and heterogeneously nucleated struvite exists that is due to the amorphous magnesium hydroxide structural units.  The presence of low coordination O4C-H, O3C-H and O1C-H surface hydroxyl groups, assocd. with the surface steps, edges and kinks is proposed to enhance struvite formation and increase in their abundance and stabilization are suggested for the MgO and MgCO3 prepn. before the struvite recovery.  Two different crystal morphologies (needle and rhomboidal) were obsd. for reactions with 600 and 4000 ppm of (NH4)2HPO4, which were proposed to form due to the kinetic control of the reaction at higher concns.  Finally, Raman spectroscopy was used to measure the relative kinetics of struvite formation utilizing the relative populations of the magnesium carbonate or struvite, as obtained from the area under the 1125 and 950 cm-1 peaks providing a spectroscopic method to monitor reactive solid magnesium source conversion into struvite.

For this purpose, surface chemistry of MgO/SiO2 catalyst synthesized using wet-kneading was explored during the reaction of ethanol and the corresponding reactive intermediates, including acetaldehyde, crotonaldehyde, crotyl alcohol using temperature programmed in situ DRIFT spectroscopy combined with DFT calculations. Ethanol adsorption yielded several physisorbed and chemisorbed surface species. Acetaldehyde exhibited high reactivity to form crotonaldehyde. However, aldehyde intermediates resulted in strongly bound surface species stable even at high temperatures, assigned to surface acetate, and/or 2,4-hexadienal or polymerized acetaldehyde. Crotonaldehyde was reduced by ethanol to yield crotyl alcohol via MPV mechanism. Crotyl alcohol, on the other hand, showed to be very reactive and yield two different species on the surface, namely physisorbed and deprotonated that would further desorb as 1,3-BD. Presence of gas phase hydrogen containing molecules, such as ethanol, proved to be key in several reactive steps, including acetaldehyde condensation step and crotonaldehyde reduction. Altogether, these data suggested complex reactive interactions between the surface hydroxyl groups, gaseous reactants and surface bound reactive intermediates during the 1,3-BD formation. Future work is needed to correlate vapor phase product evolution with the transient reactive surface intermediates to examine trends leading to higher overall 1,3-BD selectivity.</style></abstract><issue><style face="normal" font="default" size="100%">20</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Sustainable Ammonia Production</style></title><secondary-title><style face="normal" font="default" size="100%">ACS Sustainable Chemistry &amp; Engineering</style></secondary-title><short-title><style face="normal" font="default" size="100%">ACS Sustainable Chem.

Overfertilization with phosphorus can lead to its fixation in soil, as well as the unwanted environmental phenomena, such as eutrophication.  Urea phosphate, CO(NH2)2·H3PO4, based liq. fertilizers were synthesized in this work, and their resulting physicochem. properties were detd.  For this purpose, phase compn. information on the CO(NH2)2·H3PO4-CO(NH2)2-H2O ternary system was analyzed, and crit. points on the polytherm were detd.  Liq. fertilizer compns. were detd. and their corresponding physicochem. properties established.  Raman spectroscopy showed that CO(NH2)2·H3PO4 partially retains its strong bonding interactions between both mol. adducts in aq. solns. suggesting their improved nitrogen management efficiency in soils.  Effect of these acidic pH fertilizer solns. on the pH of soil was detd. and was found negligible.

The presence of Ni2O3 species at an optimal amt. seems to enhance the photocatalytic activity of Ni-MCM-48 materials in comparison to a Ni-MCM-48 mesoporous material having only NiO dispersed in it.  In addn., the presence of bulk NiO species also seems to be detrimental to the generation of solar hydrogen.  The apparent quantum yield (AQY) of the most active material, Ni-MCM-48-2.5% was estd. to be 5.35%.  This was over 250 times higher than a bulk, NiO (AQY = 0.02%) under identical exptl. conditions.

The optB86b-vdW (van der Waals) was found to have the overall best agreement with expts. concerning lattice const., bulk stress, surface energy, and methanol adsorption among PBE (Perdew-Burke-Ernzerhof), optB88-vdW, optPBE-vdW, vdW-DF (d. functional), vdW-DF2 (d. functional 2nd version), and vdW-BEEF (Bayesian error estn. functional).  Glycerol adsorption energy is found to correlate well with the calcd. d-band center of the transition-metal-contg. Au(111) surface layer.  O-H stretching vibrations are found to be very sensitive of the surface-alloy atom and resulted in large shifts toward lower wavenumbers, when compared to those on bare Au(111).  The latter results clearly show that adsorption of glycerol to surface-alloy atoms can be monitored in situ by IR spectroscopy.

Here, we develop hybrid nanostructures through the growth of hematite (α-Fe2O3) nanoparticles, which are recognized sorbents for various heavy metals, on multi-walled carbon nanotubes (MWCNTs).  The hybrid nanostructures were synthesized via hydrolysis of ferric nitrate in the presence of carboxylated MWCNTs, and their activity as sorbents toward Cu(II) and chromate (CrO42-) was examd. as a function of pH (i.e., pH-edge expts.) and initial metal concn. (i.e., adsorption isotherms).  Characterization of α-Fe2O3/MWCNT nanostructures via Raman spectroscopy and transmission electron microscopy (TEM) with selected area electron diffraction (SAED) confirmed the deposited iron phase as α-Fe2O3.  Further, complementary acid digestions and TEM imaging revealed that the amt. (0.1 and 0.5 g g-1 α-Fe2O3/MWCNT) and size [5.9 (±1.1) and 8.9 (±1.5) nm, resp.] of α-Fe2O3 nanoparticles immobilized on MWCNTs were tunable during synthesis.  Generally, mass-normalized concns. of adsorbed Cu(II) and CrO42- were greatest for α-Fe2O3/MWCNT hybrids relative to adsorption on either carboxylated MWCNTs or freely suspended α-Fe2O3 nanoparticles, with evidence implicating α-Fe2O3 as the active sorbent phase in hybrid materials.  Indeed, per unit mass of available α-Fe2O3, hybrid sorbents exhibited capacities comparable to or exceeding most other iron-based sorbents for Cu(II) and CrO42- (from 220 to 470 mg Cu(II) per g α-Fe2O3 and 60 mg CrO42- per g α-Fe2O3, resp., at pH 6 and 20 °C).  The enhanced sorption capacity of the hybrid nanostructures is due, at least in part, to the greater available surface area of α-Fe2O3 nanoparticles immobilized on MWCNTs when compared to their more extensively aggregated state in suspension.  Notable differences in the pH-dependent trends of Cu(II) and CrO42- uptake on α-Fe2O3/MWCNT hybrids, along with differences in zeta potential measurements across pH, also suggest that the immobilized α-Fe2O3 nanoparticles may exhibit unique surface reactivity relative to their freely suspended analogs as a result of their assocn. with the neg. charged MWCNT surface.

(in H2O and D2O) and quantum chem. calcns. were performed to explore the pH-dependent, reversible photohydration of trenbolone acetate (TBA) metabolites.  Photohydration of 17α-trenbolone (17α-TBOH) and 17β-trenbolone (17β-TBOH) occurred readily in simulated sunlight to yield hydrated products with incorporated H+ at C4 and OH- at either C5 (5-OH-TBOH) or C12 (12-OH-TBOH) in the tetracyclic steroid backbone.  Although unable to be elucidated anal., theory suggests preferred orientations of cis-12-OH-TBOH (relative to C13 methyl) and trans-5-OH-TBOH, with the former most thermodynamically stable overall.  Both expt. and theory indicate limited stability of trans-5-OH-TBOH at acidic pH where it undergoes concurrent, carbocation-mediated thermal rearrangement to cis-12-OH-TBOH and dehydration to regenerate its parent structure.  Expts. revealed cis-12-OH-TBOH to be more stable at acidic pH, which is the only condition where its reversion to parent TBA metabolite occurred.  At basic pH cis-12-OH-TBOH decayed quickly via hydroxide/water addn., behavior that theory attributes to the formation of a stable enolate resistant to dehydration but prone to thermal hydration.  In a noteworthy deviation from predicted theor. stability, 17α-TBOH photohydration yields major trans-5-OH-TBOH and minor cis-12-OH-TBOH, a distribution also opposite that obsd. for 17β-TBOH.  Because H+ and OH- loss from adjacent carbon centers allows trans-5-OH-TBOH to dehydrate at all pH values, the presumed kinetically controlled yield of 17α-TBOH photohydrates results in a greater propensity for 17α-TBOH reversion than 17β-TBOH.  Addnl. calcns. explored minor, but potentially bioactive, trenbolone analogs that could be generated via alternative rearrangement of the acidic carbocation intermediate.

XPS is the primary tool used for this purpose.  The spectral data obtained, however, is often very complex and can be subject to incorrect interpretation.  Unlike traditional XPS spectra fitting procedures using purely synthetic spectral components, here the authors develop and present an XPS data processing method based on vector anal. that allows creating XPS spectral components by incorporating key information, obtained exptl.  XPS spectral data, obtained from series of molybdenum oxide samples with varying oxidn. states and degree of crystallinity, were processed using this method and the corresponding oxidn. states present, as well as their relative distribution was elucidated.  Monitoring the evolution of the chem. and crystal structure of a molybdenum oxide sample due to an invasive x-ray probe could be used to infer solns. to complex spectral envelopes.

Syngas is an intermediate in large-scale long-chain hydrocarbon (C10-C20 alkanes and alcs.) prodn. processes via Fischer-Tropsch (FT) synthesis, typically to obtain high quality fuels.  Thus, it is of particular interest to engineer syngas prodn. processes for FT that can consume various combustion process waste CO2 in the process and thus partially contribute to the sustainable carbon neutral fuel synthesis.  In this work, a quant. economic comparison of five alternative processes is presented for the prodn. of synthesis gas with a hydrogen-to-carbon monoxide ratio of 2, which is suitable for feeding to the Fischer-Tropsch gas-to-liq. process.  Combinations of steam methane reforming (SMR), dry methane reforming (DMR), autothermal reforming (ATR) and reverse water gas shift (RWGS) are explored.  An amine absorber/stripper system is used for carbon dioxide removal.  The effects of the cost of natural gas and of liq. oxygen and the magnitude of a potential carbon tax are demonstrated.  With current prices of raw materials, the configuration with the lowest total annual cost (TAC) features a system composed of both SMR and DMR reactors.

The solar simulated photocatalytic H evolution from photocatalysts contg. Pd0 and TiO2 nanoclusters in periodic cubic MCM-48 and aperiodic mesoporous SiO2 was compared.  The periodicity of the mesoporous SiO2 support, the oxidn. state of Pd, the location and dispersion of Pd0 have a significant impact on the photocatalytic activity.  Periodic cubic MCM-48 mesoporous SiO2 contg. Pd0 in close contact with TiO2 exhibit superior H evolution rates compared to Pd0-TiO2 contg. aperiodic mesoporous SiO2.  The highly ordered and open 3-dimensional mesoporous cubic MCM-48 support has high surface area and facilitate good dispersion and close contact of TiO2 and Pd0.  At very low loadings of 0.1% of Pd, H yield is 560 μ mol h-1, which is among the highest reported in the literature for Pd0 contg. TiO2 based materials under solar simulated conditions.  Probably the pore architecture of the support is also an important parameter that governs the photocatalytic activity.  The Pd0-mesoporous materials in general possess higher activity than Pd2+ contg. mesoporous materials.  The photocatalysts were extensively characterized by a variety of techniques such as powder XRD, N sorption anal., transmission and scanning electron microscopic studies, photoluminescence, diffuse reflectance spectroscopy (DRS), CO Chemisorption, and XPS.

TiO2 mesoporous materials were prepd. by Evapn.-Induced Self-Assembly (EISA) process.  The resulting mesoporous materials were characterized using powder X-ray diffraction (XRD), nitrogen physisorption, Raman spectroscopy, diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM), XPS, and photoluminescence spectroscopy (PL).  The photocatalytic activities of the mesoporous materials were investigated for hydrogen prodn. under solar simulated conditions.  The non-modified TiO2 sample produced only 4 μmole H2/g catalyst after 4 h of irradn.  In contrast, the Co contg. mesoporous materials produced significantly higher amts. of hydrogen under identical conditions.  The highest solar hydrogen evolution (634 μmole H2/g catalyst after 4 h of irradn.) was from the Co-TiO2-0.5 material.  The physico-chem. characterization results indicate that the Co2+ ions are dispersed as oxide species on the surface of the mesoporous titania.

It has been detd. that the as-deposited films are lamellar with intercalated acetate ions, consisting of ZnO and α-Co(OH)2 phases.  The annealed films retain the same structure without impurities and consist of wurtzite-type ZnO and spinel-type Co3O4.  The photoelectrochem. performance and the specific capacitance of the prepd. electrodes were evaluated in 0.1 mol × L-1 NaOH aq. solns.  The obtained exptl. results showed that the values of specific capacitance increase with the increase in the amt. of cobalt (hydr)oxide.  On the contrary, the photoactivity decreases with the increase in cobalt content in the films.

Soly. can be computed from a thermodn. cycle that decomps. std. state soly. into the sum of solid-vapor sublimation and vapor-liq. solvation free energies ΔG°solubility = ΔG°sub + ΔG°solv.  Over the past few decades, alchem. simulation methods to compute solvation free energy using classical force fields have become widely used.  However, analogous methods for detg. the free energy of the sublimation/deposition phase transition are currently limited by the necessity of a priori knowledge of the at. coordinates of the crystal.  The authors describe progress toward an alternative scheme based on growth of the asym. unit into a crystal via alchemy (GAUCHE).  GAUCHE computes deposition free energy ΔG°dep = -ΔG°sub = -kBT ln(Vc/Vg) + ΔGAU + ΔGAU→UC as the sum of an entropic term to account for compressing a vapor at 1 M std. state (Vg) into the molar volume of the crystal (Vc), where kB is Boltzmann's const. and T is temp. in K, plus two simulation steps.  In the first simulation step, the deposition free energy ΔGAU for a system composed of only NAU asym. unit (AU) mol.(s) is computed beginning from an arbitrary conformation in vacuum.  In the second simulation step, the change in free energy ΔGAU→UC to expand the asym. unit degrees of freedom into a unit cell (UC) composed of NUC independent mols. is computed.  This latter step accounts for the favorable free energy of removing the constraint that every symmetry mate of the asym. unit has an identical conformation and intermol. interactions.  The current work is based on NVT simulations, which requires knowledge of the crystal space group and unit cell parameters from expt., but not a priori knowledge of cryst. at. coordinates.  GAUCHE was applied to 5 org. mols. whose sublimation free energy has been measured exptl., based on the polarizable AMOEBA force field and more than a microsecond of sampling per compd. in the program Force Field X.  The mean unsigned and RMS errors were only 1.6 and 1.7 kcal/mol, resp., which indicates that GAUCHE is capable of accurate prediction of abs. sublimation thermodn.

The pp-HMDSO films were deposited on a soda-lime-silica float glass using HMDSO monomer vapor as a precursor.  A detailed surface characterization was performed using SEM and at. force microscopy.  The growth process of the pp-HMDSO films was investigated as a function of deposition time from 30 to 300 s.  The non-wetting characteristics of the pp-HMDSO films were evaluated by means of contact angle (CA) measurements and correlated with the morphol. characteristics, as obtained from microscopy measurements.  The deposited films were found to be nano-structured and exhibited dual-scale roughness with the static CA values close to 170°.  Fourier transform IR spectroscopy anal. was carried out to investigate chem. and functional properties of these films.  Me groups were identified spectroscopically to be present within the pp-HMDSO films and were proposed to result in the low surface energy of material.  The synergy between the dual-scale roughness and low surface energy resulted in the superhydrophobic characteristics of the pp-HMDSO films.  A possible mechanism for the pp-HMDSO film formation is proposed.

We also demonstrated that varying the co-solvent, modulates the structural properties of the materials.  In particular, the use of non-polar co-solvents such as toluene seemed to increase the crystallinity, surface area, and pore diam. while the crystallite size of titania seemed to change little.  A comprehensive characterization using surface and bulk techniques evidenced the role of porosities, crystallinity, and Ti-O-Si linkages of the mixed oxides as significant factors that contribute to the degrdn. of phenol.  The TiO2-SiO2 mixed oxide material prepd. using only ethanol as the solvent showed 24% degrdn. of phenol after 120 min of irradn. whereas other mixed oxide materials degraded phenol more efficiently (57% to 100%) in the same duration of time.  The higher photocatalytic activities of the mixed oxide materials prepd. using non-polar solvents is attributed to a combination of factors that include higher Apparent Surface Coverages of Ti-O-Si heterolinkages, larger pore sizes, and most importantly higher crystallinities of the titania phase.  Larger pore sizes enabled better transport of reactant mols. and products to and from the active sites (Ti-O-Si heterolinkages) and the higher crystallinities of the titania phase helped in minimizing the electron-hole recombination in these photocatalysts, and thus resulted in high degrdn. efficiencies.

Because of these differences, individual particles should display a range of reactivities with trace atm. gases.  We studied the compn. of individual sea spray aerosol particles after heterogeneous reaction with nitric acid.  As expected, a replacement reaction of chloride with nitrate is obsd.; however, there is a large range of reactivities spanning from no reaction to complete reaction between and within individual sea spray aerosol particles.

A highly efficient (24.8%, apparent quantum yield (AQY)) photocatalyst for visible light (λ &gt; 400 nm) enabled solar hydrogen evolution can be realized by assembling CdS with Ti-MCM-48 cubic mesoporous materials in the absence of a noble metal co-catalyst.  The photocatalytic mechanism was thoroughly investigated and demonstrated by conducting a wealth of characterization techniques such as powder X-ray diffraction (XRD), nitrogen adsorption isotherm, transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy (DRS), XPS, UPS (UVPS), at. absorption spectroscopy (AAS), photoluminescence (PL) spectroscopy, time-resolved fluorescence emission decay, and ESR (EPR) spectroscopy studies.  This work is the first to unambiguously identify the band positions of both CdS and TiO2 encapsulated in porous materials.  The photocatalytic activity of the CdS incorporated Ti-MCM-48 mesoporous photocatalysts was found to be dependent on the content of both CdS and TiO2.  A correlation between the electron injection efficiency and the photocatalytic activity was established as well in the CdS incorporated Ti-MCM-48 mesoporous photocatalysts.

Since iron concns. are extremely low in body fluids, there is potential that iron-contg. nanoparticles may influence the ability of bacteria to scavenge iron for growth, affect virulence and inhibit antimicrobial peptide (AMP) function.  In this study, Pseudomonas aeruginosa (PA01) and AMPs were exposed to iron oxide nanoparticles, hematite (α-Fe2O3), of different sizes ranging from 2 to 540 nm (2 ± 1, 43 ± 6, 85 ± 25 and 540 ± 90 nm) in diam.  Here we show that the greatest effect on bacterial growth, biofilm formation, and AMP function impairment is found when exposed to the smallest particles.  These results are attributed in large part to enhanced dissoln. obsd. for the smallest particles and an increase in the amt. of bioavailable iron.  Furthermore, AMP function can be addnl. impaired by adsorption onto nanoparticle surfaces.  In particular, lysozyme readily adsorbs onto the nanoparticle surface which can lead to loss of peptide activity.  Thus, this current study shows that co-exposure of nanoparticles and known pathogens can impact host innate immunity.

Here, we explore the ability of carbon nanotubes with nitrogen-contg. surface groups (N-CNTs) to generate N-nitrosodimethylamine (NDMA) during chem. disinfection.  Unexpectedly, we obsd. that com. N-CNTs with amine, amide, or N-contg. polymer (PABS) surface groups are a source of NDMA.  As-received powders can leach up to 50 ng of NDMA per mg of N-CNT in aq. suspension; presumably NDMA originates as a residue from N-CNT manufg.  Furthermore, reaction of N-CNTs with free chlorine, monochloramine, and ozone generated byproduct NDMA at yields comparable to those reported for natural org. matter.  Chlorination also altered N-CNT surface chem., with XPS indicating addn. of Cl, loss of N, and an increase in surface O.  Although these changes can increase N-CNT suspension stability, they do not enhance their acute toxicity in E. coli bioassays above that obsd. for as-received powders.  Notably, however, dechlorination of reacted N-CNTs with sulfite completely suppresses N-CNT toxicity.  Collectively, our work demonstrates that N-CNTs are both a source and precursor of NDMA, a probable human carcinogen, while chem. disinfection can produce CNTs exhibiting surface chem. and environmental behavior distinct from that of native (i.e., as-received) materials.

(PEC) decompn. of org. compds. in wastewater is investigated by using quantum chem. (DFT) methods to evaluate alternatives to water splitting for the prodn. of renewable and sustainable hydrogen.  Methanol is used as a model org. species for the theor. evaluations of electrolysis on the surface of the widely available semiconductor hematite, α-Fe2O3, a widely studied photocatalyst.  Three different α-Fe2O3 surface terminations were investigated, including the predominant surface found in aq. electrolytes, (OH)3-R.  The PEC oxidn. of methanol is energetically downhill, producing CO2 and protons.  The protons are reduced to hydrogen on the cathode.  Exptl. PEC measurements were also performed for several polyalcoholic compds., glycerol, erythritol, and xylitol, on α-Fe2O3 as the photocatalyst and showed high incident-photon-to-current-efficiencies (IPCE) that were much greater than those of water splitting.  Interestingly, high IPCEs were obsd. for hydrogen prodn. from polyalcs. in the absence of any applied bias, which was not thought to be possible on hematite.  These results support the potential application of PEC for hydrogen prodn. by using widely available hematite for the PEC oxidn. of selected components of org. wastewater present in large quantities from anthropogenic and industrial sources.

Following exposure of α-Fe2O3 particle surfaces to gas-phase nitric acid, a peak in the N1s region is seen at 407.4 eV; this binding energy is indicative of adsorbed nitrate.  Upon broadband irradn. with light (λ &gt; 300 nm), the nitrate peak decreases in intensity as a result of a decrease in adsorbed nitrate on the surface.  Concomitant with this decrease in the nitrate coverage, there is the appearance of two lower binding energy peaks in the N1s region at 401.7 and 400.3 eV, due to reduced nitrogen species.  The formation as well as the stability of these reduced nitrogen species, identified as NO- and N-, are further investigated as a function of water vapor pressure.  Addnl., irradn. of adsorbed nitrate on α-Fe2O3 generates three nitrogen gas-phase products including NO2, NO, and N2O.  As shown here, different environmental conditions of water vapor pressure and the presence of mol. oxygen greatly influence the relative photoproduct distribution from nitrate surface photochem.  The atm. implications of these results are discussed.

Despite decades of marine environment studies, a direct relationship has yet to be established between ocean biol. and physicochem. SSA properties.  The ability to establish such relationships is hindered because SSA measurements are typically dominated by overwhelming background aerosol concns., even in remote marine environments.  This work describes a newly developed approach to reproduce SSA chem. complexity a lab. setting, comprising a unique ocean/atm. facility equipped with actual breaking waves.  A mesocosm expt., performed with natural seawater using controlled phytoplankton and heterotrophic bacteria concns., showed SSA size and chem. mixing state are acutely sensitive to the aerosol prodn. mechanism and to the type of biol. species present.  The largest redn. in SSA hygroscopicity occurred as heterotrophic bacteria concns. increased, whereas phytoplankton and chlorophyll-a concns. decreased, directly corresponding to a change in mixing state in the smallest size range (60-180 nm).  Using this newly developed approach to generate realistic SSA, systematic studies can now be performed to advance the fundamental understanding of the effect of ocean biol. on SSA chem. mixing state, heterogeneous reactivity, and resulting climate-relevant properties.

Since free iron concns. are extremely low in airway surface liq. (ASL), we hypothesize that CFA impairs antimicrobial peptides (AMP) function and can be a source of iron to bacteria.  We tested this hypothesis in vivo by instilling mice with Pseudomonas aeruginosa (PA01) and CFA and det. the percentage of bacterial clearance.  In addn., we tested bacterial clearance in cell culture by exposing primary human airway epithelial cells to PA01 and CFA and detg. the AMP activity and bacterial growth in vitro.  We report that CFA is a bioavailable source of iron for bacteria.  We show that CFA interferes with bacterial clearance in vivo and in primary human airway epithelial cultures.  Also, we demonstrate that CFA inhibits AMP activity in vitro, which we propose as a mechanism of our cell culture and in vivo results.  Furthermore, PA01 uses CFA as an iron source with a direct correlation between CFA iron dissoln. and bacterial growth.  CFA concns. used are very relevant to human daily exposures, thus posing a potential public health risk for susceptible subjects.  Although CFA provides a source of bioavailable iron for bacteria, not all CFA particles have the same biol. effects, and their propensity for iron dissoln. is an important factor.  CFA impairs lung innate immune mechanisms of bacterial clearance, specifically AMP activity.  We expect that identifying the PM mechanisms of respiratory infections will translate into public health policies aimed at controlling, not only concn. of PM exposure, but physicochem. characteristics that will potentially cause respiratory infections in susceptible individuals and populations.

Despite many epidemiological reports showing effects of volcanic ash on the respiratory system, there are limited data evaluating cellular mechanisms involved in the response to ash.  Epidemiological studies have observed an increase in respiratory infections in subjects and populations exposed to volcanic eruptions.  METHODS:  We physicochemically characterized volcanic ash, finding various sizes of particles, as well as the presence of several transition metals, including iron.  We examined the effect of Eyjafjallajokull ash on primary rat alveolar epithelial cells and human airway epithelial cells (20-100 μg/cm(2)), primary rat and human alveolar macrophages (5-20 μg/cm(2)), and Pseudomonas aeruginosa (PAO1) growth (3 μg/104 bacteria).  RESULTS:  Volcanic ash had minimal effect on alveolar and airway epithelial cell integrity.  In alveolar macrophages, volcanic ash disrupted pathogen-killing and inflammatory responses.  In in vitro bacterial growth models, volcanic ash increased bacterial replication and decreased bacterial killing by antimicrobial peptides.  CONCLUSIONS:  These results provide potential biological plausibility for epidemiological data that show an association between air pollution exposure and the development of respiratory infections.  These data suggest that volcanic ash exposure, while not seriously compromising lung cell function, may be able to impair innate immunity responses in exposed individuals.[on SciFinder (R)]</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><notes><style face="normal" font="default" size="100%">MEDLINE AN 2013450089(Journal; Article; (JOURNAL ARTICLE); (RESEARCH SUPPORT, N.I.H., EXTRAMURAL); (RESEARCH SUPPORT, U.S. GOV'T, NON-P.H.S.))</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Mahoney, Luther</style></author><author><style face="normal" font="default" size="100%">Wu, Chia-Ming</style></author><author><style face="normal" font="default" size="100%">Kibombo, Harrison S.</style></author><author><style face="normal" font="default" size="100%">Thiruppathi, Eagappanath</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author><author><style face="normal" font="default" size="100%">Rasalingam, Shivatharsiny</style></author><author><style face="normal" font="default" size="100%">Koodali, Ranjit T.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Exploration of the role of anions in the synthesis of Cr containing mesoporous materials at room temperature.</style></title><secondary-title><style face="normal" font="default" size="100%">Microporous and Mesoporous Materials</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">anion chromium mesoporous material room temp</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2013</style></year></dates><publisher><style face="normal" font="default" size="100%">Elsevier Inc.</style></publisher><volume><style face="normal" font="default" size="100%">170</style></volume><pages><style face="normal" font="default" size="100%">211 - 225</style></pages><isbn><style face="normal" font="default" size="100%">1387-1811</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Chromium contg. mesoporous silica materials were synthesized via a modified Stoeber synthesis at room temp.

Large portions of natural gas resources are still too expensive to process due to their high content of hydrogen sulfide gas (H2S) mixed with methane, deemed altogether as sub-quality or &quot;sour&quot; gas.  We propose a unique method of activation to form a mixt. of sulfur-contg. hydrocarbon intermediates, CH3SH and CH3SCH3, and an energy carrier such as H2.  For this purpose, we investigated the H2S-mediated methane activation to form a reactive CH3SH species by means of direct photolysis of sub-quality natural gas.  Photoexcitation of hydrogen sulfide in the CH4 + H2S complex resulted in a barrierless relaxation by a conical intersection to form a ground-state CH3SH + H2 complex.  The resulting CH3SH could further be coupled over acidic catalysts to form higher hydrocarbons, and the resulting H2 used as a fuel.  This process is very different from conventional thermal or radical-based processes and can be driven photolytically at low temps., with enhanced control over the conditions currently used in industrial oxidative natural gas activation.  Finally, the proposed process is CO2 neutral, as opposed to the current industrial steam methane reforming (SMR).

Heterogeneous chem. and the uptake of org. acids on mineral dust particles can potentially alter the properties of the particle.  In this study, heterogeneous uptake and reaction of formic acid, HCOOH, the most abundant carboxylic acid present in the atm., on oxide and clays of the most abundant elements, Si and Al, present in the Earth's crust are investigated under dry and humid conditions.  In particular, quant. adsorption measurements using a Quartz Crystal Microbalance (QCM) coupled with spectroscopic studies using Attenuated Total Reflection Fourier Transform IR (ATR-FTIR) spectroscopy are combined to allow for both quantification of the amt. of uptake and identification of distinct adsorbed species formed on silica, alumina, and kaolinite particle surfaces at 298 K.  These oxides and clay particles show significant differences in the extent and speciation of adsorbed HCOOH due to inherent differences in surface -OH group reactivity.  Adsorbed water, controlled by relative humidity, can increase the irreversible uptake of formic acid.  Interestingly, the resulting layer of adsorbed formate on the particle surface decreases the particle hydrophilicity thereby decreasing the amt. of water taken up by the surface as measured by QCM.  Atm. implications of this study are discussed.

Therefore, we investigated the phototransformation of TBA metabolites and assocd. ecol. implications by characterizing the photoproducts arising from the direct photolysis of 17β-TBOH, 17α-TBOH, and TBO and their assocd. ecotoxicity.  LC-HRMS/MS anal. identified a range of hydroxylated products that were no longer photoactive, with primary photoproducts consisting of monohydroxy species and presumptive diastereomers.  Also obsd. were higher-order hydroxylated products probably formed via subsequent reaction of primary photoproducts.  NMR anal. confirmed the formation of 12,17-dihydroxy-estra-5(10),9(11),dien-3-one (12-hydroxy-TBOH; 2.2 mg), 10,12,17-trihydroxy-estra-4,9(11),dien-3-one (10,12-dihydroxy-TBOH; 0.7 mg), and a ring-opened 11,12-dialdehyde oxidn. product (TBOH-11,12-dialdehyde; 1.0 mg) after irradn. of ∼14 mg of 17β-trenbolone.  Though unconfirmed by NMR, our data suggest that the formation of addnl. isomeric products may occur, likely due to the reactivity of the unique 4,9,11 conjugated triene structure of trenbolone.  In vivo exposure studies employing Japanese medaka (Oryzias latipes) indicate that low concns. of 17α-TBOH photoproduct mixts. can alter ovarian follicular development, and photoproducts alter whole-body 17β-estradiol levels.  Therefore, direct photolysis yields photoproducts with strong structural similarity to parent steroids, and these photoproducts still retain enough biol. activity to elicit observable changes to endocrine function at trace concns.  These data indicate that environmental transformation processes do not necessarily reduce steroid hormone ecotoxicity.

We performed lab. and field phototransformation expts. to assess the fate of TBA metabolites and their photoproducts.  Unexpectedly, we obsd. that the rapid photohydration of TBA metabolites is reversible under conditions representative of those in surface waters (pH 7, 25°C).  This product-to-parent reversion mechanism results in diurnal cycling and substantial regeneration of TBA metabolites at rates that are strongly temp.- and pH-dependent.  Photoproducts can also react to produce structural analogs of TBA metabolites.  These reactions also occur in structurally similar steroids, including human pharmaceuticals, which suggests that predictive fate models and regulatory risk assessment paradigms must account for transformation products of high-risk environmental contaminants such as endocrine-disrupting steroids.

WO3 growth is highly selective for Pt when present on silicon in a patterned arrangement, demonstrating that Pt catalyzes decompn. of the WO3 precursor in soln.  The obtained Pt/WO3 interface yields high photocurrents of 1.1 mA/cm2 in photoelectrochem. water splitting when illuminated by a solar simulator.  The photocurrents are significantly higher than most previously reported values for hydrothermally grown layers on indium-tin oxide and fluorine-tin oxide glasses.  The selective growth method thus provides new options to effectively implement WO3 in photoelectrochem. devices.

Single particle anal. of SSA particles was performed, integrating transmission electron microscopy with energy dispersive x-ray anal. and scanning transmission x-ray microscopy with near edge x-ray absorption fine structure spectroscopy, focusing on quantifying the relative fractions of different particle types from 30 nm to 1 μm.  SSA particles were produced from seawater in a unique ocean/atm. facility equipped with breaking waves.  Changes to SSA compn. and properties after adding biol. (bacteria, phytoplankton) and org. material (ZoBell growth media) were probed.  Sub-micrometer SSA particles could be sepd. into 2 distinct populations: one with a characteristic sea-salt core composed primarily of NaCl and an org. C and Mg2+ coating (SS-OC); and a second type consisting of org. C (OC) species more homogeneously mixed with cations and anions, but not Cl-.  SS-OC particles exhibited a range of sizes, compns., morphologies, and element distributions within each particle.  Following addn. of biol. and org. material to seawater, a change occurred in particle morphol. and crystn. behavior assocd. with increasing org. content for SS-OC particles.  The fraction of OC-type particles, mainly present at &lt;180 nm, was dramatically enhanced with increased biol. activity.  These changes with size and seawater compn. have important implications for atm. processes, e.g., cloud droplet activation and heterogeneous reactivity.

This review highlights recent developments and future perspectives in carbon dioxide usage for the sustainable prodn. of energy and chems. and to reduce global warming.  We discuss the heterogeneously catalyzed hydrogenation, as well as the photocatalytic and electrocatalytic conversion of CO2 to hydrocarbons or oxygenates.  Various sources of hydrogen are also reviewed in terms of their CO2 neutrality.  Technologies have been developed for large-scale CO2 hydrogenation to methanol or methane.  Their industrial application is, however, limited by the high price of renewable hydrogen and the availability of large-vol. sources of pure CO2.  With regard to the direct electrocatalytic redn. of CO2 to value-added chems., substantial advances in electrodes, electrolyte, and reactor design are still required to permit the development of com. processes.  Therefore, in this review particular attention is paid to (i) the design of metal electrodes to improve their performance and (ii) recent developments of alternative approaches such as the application of ionic liqs. as electrolytes and of microorganisms as co-catalysts.  The most significant improvements both in catalyst and reactor design are needed for the photocatalytic functionalization of CO2 to become a viable technol. that can help in the usage of CO2 as a feedstock for the prodn. of energy and chems.  Apart from technol. aspects and catalytic performance, we also discuss fundamental strategies for the rational design of materials for effective transformations of CO2 to value-added chems. with the help of H2, electricity and/or light.

The photocatalytic performances of these materials were evaluated by monitoring the amt. of hydrogen evolved from water under visible light irradn.  The amt. of hydrogen evolved from MBA stabilized CdS-TNT composite materials were higher compared to MBA stabilized CdS, suggesting an important role of the TNT support.  The enhanced photocatalytic hydrogen generation in MBA stabilized CdS-TNT composite materials compared to CdS-MBA might have arisen from the effective charge sepn. in CdS-TNT composite materials, which was further supported by PL studies.

The physicochem. properties of the composite materials were characterized by XPS and high-resoln. transmission electron microscopy.  Energy dispersive X-ray spectroscopy measurements confirmed the presence of Pt species existing as PtO2 and/or mixts. of Pt0 and PtO2.  The composite material, Pt-TiO2-2%H, contained a high amt. of metallic Pt0 and PtO2 in close proximity with TiO2 that promoted an enhanced photocatalytic hydrogen evolution activity under simulated solar light irradn.  Although Pt-TiO2-2%C and Pt-TiO2-2%T consisted of similar compns. of PtO2, these oxidized platinum species seem to appear further apart from TiO2 in Pt-TiO2-2%C than Pt-TiO2-2%T.  This caused dramatic variation in their optical behaviors such as strong fluorescence quenching and lower photocatalytic hydrogen evolution activity in the former photocatalyst.  A photocatalyst prepd. by the conventional photodeposition method was also prepd., characterized, and its photocatalytic activity assessed.  This work provides an opportunity to understand the role of PtO2 for photocatalytic prodn. of hydrogen from platinized TiO2 composites and the importance of heterojunctions in such photocatalysts for solar energy conversion.

HBr.  Co- and Ni-substituted RuS2 were identified as potentially active HER electrocatalysts by high-throughput screening (HTS), and the specific compns. Co0.4Ru0.6S2 and Ni0.6Ru0.4S2 were identified by optimization.  H evolution activity of Co0.4Ru0.6S2 in HBr is greater than RuS2 or CoS2 and comparable to Pt and com. RhxSy.  Structural and morphol. characterizations of the Co-substituted RuS2 suggest that the nanoparticulate solids are a homogeneous solid soln. with a pyrite crystal structure.  No phase sepn. is detected for Co substitutions &lt;30% by x-ray diffraction.  In 0.5 M HBr electrolyte, the Co-Ru electrode material synthesized with 30% Co rapidly lost ∼34% of the initial loading of Co; thereafter, it was obsd. to exhibit stable activity for HER with no further loss of Co.  D. functional theory calcns. indicate that the S22- sites are the most important for HER and the presence of Co influences the S22- sites such that the H binding energy at sufficiently high H coverage is decreased compared to Ru sulfide.  Although showing high HER activity in a flow cell, the reverse reaction of H oxidn. is slow on the RuS2 catalysts tested when compared to Pt and Rh sulfide, leaving Rh sulfide as the only suitable tested material for a regenerative HBr cell due its stability compared to Pt.

(a.c.) mode at. force microscopy (AFM) combined with phase imaging and XPS were used to study the effect of nitrogen dioxide (NO2) adsorption on calcium carbonate (CaCO3) (101̅4) surfaces at 296 K in the presence of relative humidity (RH).  At 70% RH, CaCO3 (101̅4) surfaces undergo rapid formation of a metastable amorphous calcium carbonate layer, which in turn serves as a substrate for recrystn. of a nonhydrated calcite phase, presumably vaterite.  The adsorption of nitrogen dioxide changes the surface properties of CaCO3 (101̅4) and the mechanism for formation of new phases.  In particular, the 1st calcite nucleation layer serves as a source of material for further island growth; when it is depleted, there is no change in total vol. of nitrocalcite, Ca(NO3)2, particles formed whereas the total no. of particles decreases.  These particles are mobile and coalesce.  Phase imaging combined with force curve measurements reveals areas of inhomogeneous energy dissipation during the process of water adsorption in relative humidity expts., as well as during nitrocalcite particle formation.  Potential origins of the different energy dissipation modes within the sample are discussed.  Finally, XPS anal. confirms that NO2 adsorbs on CaCO3 (101̅4) as nitrate (NO3-) regardless of environmental conditions or the pretreatment of the calcite surface at different relative humidity.

Few measurements have been made that compare the soly. of atm. iron from anthropogenic aerosols and other sources.  We report here an investigation of iron dissoln. for three FA samples in acidic aq. solns. and compare the solubilities with that of Arizona test dust (AZTD), a ref. material for mineral dust.  The effects of pH, simulated cloud processing, and solar radiation on iron soly. have been explored.  Similar to previously reported results on mineral dust, iron in aluminosilicate phases provides the predominant component of dissolved iron.  Iron soly. of FA is substantially higher than of the cryst. minerals comprising AZTD.  Simulated atm. processing elevates iron soly. due to significant changes in the morphol. of aluminosilicate glass, a dominant material in FA particles.  Iron is continuously released into the aq. soln. as FA particles break up into smaller fragments.  These results suggest that the assessment of dissolved atm. iron deposition fluxes and their effect on the biogeochem. at the ocean surface should be constrained by the source, environmental pH, iron speciation, and solar radiation.

(RSC), H2S and CH3SH, were investigated using ground and excited state d. functional theory (DFT) and coupled cluster (CC) methods to explore possible RSC oxidn. mechanisms and CO2 activation mechanisms in the atm. environment.  Ground electronic state calcns. at the CR-CC(2,3)/6-311+G(2df,2p)//CAM-B3LYP/6-311+G(2df,2p) level show proton transfer as a limiting step in the redn. of CO2 with activation energies of 49.64 and 47.70 kcal/mol, resp., for H2S and CH3SH.  On the first excited state surface, CR-EOMCC(2,3)/6-311+G(2df,2p)//CAM-B3LYP/6-311+G(2df,2p) calcns. reveal that energies of &lt;250 nm are needed to form H2S-CO2 and CH3SH-CO2 complexes allowing facile hydrogen atom transfer.  Once excited, all reaction intermediates and transition states are downhill energetically showing either C-H or C-S bond formation in the excited state whereas only C-S bond formation was found in the ground state.  Environmental implications of these data are discussed with a focus on tropospheric reactions between CO2 and RSC, as well as potential for carbon sequestration using photocatalysis.

(oxalate) reductive dissoln.  Empirical relations between dissoln. rate and pH revealed that suspensions of 8 nm hematite exhibit between 3.3- and 10-fold greater reactivity per unit mass than suspensions of 40 nm particles across all dissoln. modes and pH, including circumneutral.  Complementary suspension characterization (i.e., sedimentation studies and dynamic light scattering) indicated extensive aggregation, with steady-state aggregate sizes increasing with pH but being roughly equiv. for both primary particles.  Thus, while the reactivity difference between 8 and 40 nm suspensions is generally greater than expected from sp. surface areas measured via N2-BET or estd. from primary particle geometry, loss of reactive surface area during aggregation limits the certainty of such comparisons.  Probably the relative reactivity of 8 and 40 nm hematite suspensions is best explained by differences in the fraction of aggregate surface area that is reactive.  This scenario is consistent with TEM images revealing uniform dissoln. of aggregated 8 nm particles, whereas 40 nm particles within aggregates undergo preferential etching at edges and structural defects.  Ultimately, comparably sized hematite aggregates can exhibit vastly different dissoln. activity depending on the nature of the primary nanoparticles from which they are constructed, a result with wide-ranging implications for iron redox cycling.

Natural α-Al2O3 (corundum) can contain up to 9.17% (wt./wt.) Fe2O3 and 1.81% (wt./wt.) of Cr2O3.  Here the authors report on changes in the structural and electronic properties of undoped and doped α-Al2O3 (0001) surfaces using periodic d. functional theory (DFT) methods with spin unrestricted B3LYP functional and a local at. basis set.  Both structural and electronic properties are altered upon doping.  Implications for doping effects on photochem. processes are discussed.  As metal oxides are major components of the environment, including atm. mineral aerosol, DFT was also used to study the effect of transition metal impurities on gas/surface interactions of a model acidic atm. gas mol., CO.  The theor. results indicated that the presence of Fe3+ and Cr3+ impurities substituted on the outer layer of natural corundum surfaces reduces the propensity toward CO adsorption relative to the undoped surface.  However, CO-surface interactions resemble that of bulk α-Al2O3 when the impurity is substituted below the 1st surface layer.  The presence and location of the mineral dopant significantly altered the structural and electronic properties and gas/surface interactions studied here.

The resultant materials were characterized by powder X-ray diffraction (XRD), nitrogen physisorption studies, Raman spectroscopy, XPS, diffuse reflectance spectroscopy (DRS), photoluminescence (PL) spectroscopy, and transmission electron microscopy (TEM).  The photocatalytic performances of these materials were evaluated by calcg. the amt. of hydrogen evolved from the decompn. of water under solar simulated irradn. conditions.  An improvement was achieved from no H2 evolution at all with the bare TiO2, to an evolution of 0.21 mL g-1 h-1 from a composite material modified with an optimum carbon loading of 3.62%.  These results suggested that the interaction of carbon with predominantly rutile form of TiO2 can promote shallow trapping of photogenerated electrons in the oxygen vacancies.  This phenomenon consequently enhances the photocatalytic activity by minimizing charge carrier recombination, a characteristic demonstrated by fluorescence quenching of the TiO2 emission.

We combined synchrotron-based grazing incidence small-angle x-ray scattering (GISAXS) and SAXS and other nanoparticle and substrate surface characterization techniques to observe Fe(III) (hydr)oxide [10-4M Fe(NO3)3 in 10mM NaNO3] pptn. on quartz and on polyaspartate- and alginate-coated glass substrates and in soln. (pH =3.7±0.2).  Polyaspartate was detd. to be the most neg. charged substrate and quartz the least; however, after 2 h, total nanoparticle vol. calcns.-from GISAXS-indicate that pos. charged pptn. on quartz is twice that of alginate and 10 times higher than on polyaspartate, implying that electrostatics do not govern Fe(III) (hydr)oxide nucleation.  On the basis of contact angle measurements and surface characterization, we concluded that the degree of hydrophilicity may control heterogeneous nucleation on quartz and org.-coated substrates.  The arrangement of functional groups at the substrate surface (-OH and -COOH) may also contribute.  These results provide new information for elucidating the effects of polymeric org. substrate coatings on the size, vol., and location of nucleating Fe hydroxides, which will help predict nanoparticle interactions in natural and engineered systems.

In particular, PbO particles, a model Pb-contg. compd. due to its widespread presence as a Pb paint and as naturally-occurring mineral (massicot, and litharge) component, were exposed to NO2 at different relative humidities.  XPS showed that upon exposure to NO2, the PbO particle surface reacts forming adsorbed NO3- and Pb(NO3)2 thin films; the extent of NO3- formation was relatively humidity dependent.  NO2-exposed PbO particles had an increased amt. of Pb which dissolved in aq. suspensions at circumneutral pH vs. unexposed particles.  Results identified the potential importance and impact that heterogeneous chem. with trace atm. gases can have on increasing soly. and hence the mobilization of heavy metals such as Pb in the environment.

A therapeutic strategy that may escape viral resistance is targeting host cellular mechanisms involved in viral replication and pathogenesis.  The endoplasmic reticulum (ER) stress response, also known as the unfolded protein response (UPR), is a primitive, evolutionary conserved mol. signaling cascade that has been implicated in multiple biol. phenomena including innate immunity and the pathogenesis of certain viral infections.  We investigated the effect of influenza A viral infection on ER stress pathways in lung epithelial cells.  Influenza A virus induced ER stress in a pathway-specific manner.  We showed that the virus activates the IRE1 pathway with little or no concomitant activation of the PERK and the ATF6 pathways.  When we examd. the effects of modulating the ER stress response on the virus, we found that the mol. chaperone tauroursodeoxycholic acid (TUDCA) significantly inhibits influenza A viral replication.  In addn., a specific inhibitor of the IRE1 pathway also blocked viral replication.  Our findings constitute the first evidence that ER stress plays a role in the pathogenesis of influenza A viral infection.  Decreasing viral replication by modulating the host ER stress response is a novel strategy that has important therapeutic implications.

Adsorption energy calcns. show that MgO doping will provide stronger interactions of the adsorbate with the Osurf sites than the undoped MgO for a given adsorbate mol.  Charge transfer from the iron atom in Fe-doped MgO(001) to NO2 was shown to increase the binding interaction between adsorbate by an order of magnitude, when compared to that of undoped and Ca-doped MgO(001) surfaces.  Secondary binding interactions of adsorbate oxygen atoms were obsd. with surface magnesium sites at distances close to those of the Mg-O bond within the crystal.  These interactions may serve as a preliminary step for adsorption and facilitate further adsorbate transformations into other binding configurations.  Impacts on global atm. chem. are discussed as these adsorption phenomena can affect atm. gas budgets via altered partitioning and retention on mineral aerosol surfaces.

Hydrophobic surface coatings offer a potential route to protect existing stonework in cultural heritage sites, however, many available coatings act by blocking the stone microstructure, preventing it from 'breathing' and promoting mold growth and salt efflorescence.  Here we report on a conformal surface modification method using self-assembled monolayers of naturally sourced free fatty acids combined with sub-monolayer fluorinated alkyl silanes to generate hydrophobic (HP) and super hydrophobic (SHP) coatings on calcite.  We demonstrate the efficacy of these HP and SHP surface coatings for increasing limestone resistance to sulfation and thus retarding gypsum formation under SO2/H2O and model acid rain environments.  SHP treatment of 19th century stone from York Minster suppresses sulfuric acid permeation.

Applying this strategy to quinine suggested complementary synthetic approaches to construct C-C bonds attached at the nitrogen-bearing stereogenic center using multifunctional alkyl iodides, e.g, I, as radical precursors, or using multifunctional chiral N-acylhydrazones, e.g., II, as radical acceptors.  These were included among Mn-mediated radical addns. of various alkyl iodides to a range of chiral N-acylhydrazone radical acceptors, leading to the discovery that pyridine and alkene functionalities are incompatible.  In a revised strategy, these functionalities are avoided during the Mn-mediated radical addn. of I to chiral N-acylhydrazone II, which generated a key C-C bond with complete stereochem. control at the chiral amine carbon of quinine.  Subsequent elaboration included two sequential cyclizations to complete the azabicyclo[2.2.2]octane ring system.  Group selectivity between two 2-iodoethyl groups during the second cyclization favored an undesired azabicyclo[3.2.1]octane ring system, an outcome that was found to be consistent with transition state calcns. at the B3LYP/6-31G(d) level.  Group differentiation at an earlier stage enabled an alternative regioconvergent pathway; this furnished the desired azabicyclo[2.2.2]octane ring system and afforded quincorine, completing a formal synthesis of quinine.

Soly. can be defined as the satg. concn. of a mol. within a liq. solvent, where the phys. picture is of solvated mols. in equil. with their solid phase.  Despite the importance of soly. in detg. the oral bioavailability of pharmaceuticals, prediction tools are currently limited to quant. structure-property relationships that are fit to exptl. soly. measurements.  For the first time, we describe a consistent procedure for the prediction of the structure, thermodn. stability, and soly. of org. crystals from mol. dynamics simulations using the polarizable multipole AMOEBA force field.  Our approach is based on a thermodn. cycle that decomps. std. state soly. into the sum of solid-vapor sublimation and vapor-liq. solvation free energies ΔGsolubility° = ΔGsub° + ΔGsolv°, which are computed via the orthogonal space random walk (OSRW) sampling strategy.  Application to the n-alkylamides series from acetamide through octanamide was selected due to the dependence of their soly. on both amide hydrogen bonding and the hydrophobic effect, which are each fundamental to protein structure and soly.  On av., the calcd. abs. std. state soly. free energies are accurate to within 1.1 kcal/mol.  The exptl. trend of decreasing soly. as a function of n-alkylamide chain length is recapitulated by the increasing stability of the cryst. state and to a lesser degree by decreasing favorability of solvation (i.e., the hydrophobic effect).  Our results suggest that coupling the polarizable AMOEBA force field with an orthogonal space based free energy algorithm, as implemented in the program Force Field X, is a consistent procedure for predicting the structure, thermodn. stability, and soly. of org. crystals.

Lab. synthesized α-FeOOH of varying sizes (microrods and nanorods) when exposed to gas phase H2O and HNO3 results in the uptake of these gases.  This combined approach of QCM measurements and ATR-FTIR spectroscopy allows for both quantification of the amt. of uptake and spectroscopic data that provides information on speciation of adsorbed products.  In the case of H2O, both microrods and nanorods take up H2O and that the total amts. of H2O, when normalized to surface area, are similar.  However, for HNO3 uptake, the satn. coverage of total and irreversibly bound HNO3 on microrods is higher than that on nanorods, a size effect which is attributed to surface structural changes that occur as a function of particle size.  Also, a study of the behavior of HNO3 reacted with α-FeOOH in aq. media was carried out such as to better understand the effects of atm. processing upon dispersal within the hydrosphere.

In the absence of water vapor (&lt;1% relative humidity, RH), following exposure to CO2 different species formed on the oxide surface due to the presence of adsorption sites with different basicities.  While the majority surface species on Fe2O3, γ-Al2O3 is detd. to be adsorbed bicarbonate, on TiO2 nanoparticles bidentate carbonate was more prevalent.  A carboxylate species was obsd. on TiO2 nanoparticles under dry conditions as well.  When water is present at 40% RH, the nature of the adsorbed CO2 species changed to that of solvated carbonate formation in the adsorbed water layer.  Obsd. initial adsorption rates were calcd. from time-course expts. under dry conditions and in the presence of 40% RH.  When initial adsorption rates were compared between dry and wet expts., a larger value was found for dry expts. suggesting that CO2 mols. have to compete for adsorption sites with water on these nanoparticle surfaces.  As discussed here, quantum chem. calcns. provide some addnl. insights into CO2 adsorption on hydroxylated metal oxide surfaces in the presence and absence of molecularly adsorbed water.

Soln. NMR spectroscopy and quantum chem. calcns. support the isomerization to generate two diastereomers.  The NMR data, however, could not lead to unambiguous configurational assignments of the two isomers.  Single-crystal X-ray diffraction was employed to det. each configuration.  One isomer readily crystd. as a pure form and X-ray diffraction revealed the mol. as being achiral based on Ci symmetry.  The second isomer resisted crystn. under a variety of conditions.  Consequently, a strategy based on a cocrystn. was developed to generate single crystals of the second isomer.  Cocrystn. of the isomer with a carboxylic acid readily afforded single crystals that confirmed a chiral ladderane based on C2 symmetry.  The chiral ladderane and acid self-assembled to generate a five-component hydrogen-bonded complex that packs to form large solvent-filled homochiral channels of nanometer-scale dimensions.

Aged and oxidized copper nanoparticles with an av. primary particle size of ∼15 nm, when combined with hydrochloric acid solns. in the range of 0.025 to 0.1 M, show interesting behavior yielding both a change in nanoparticle primary size, as measured by an electrospray scanning mobility particle sizer, and in chem. compn. to produce a copper chloride hydroxide mineral identified as paratacamite (γ-Cu2(OH)3Cl) by powder X-ray diffraction of the dehydrated solid sample.  Taken together, these data suggest that paratacamite nanoparticles in soln. can aggregate to yield microporous paratacamite materials.  Microporous paratacamite was characterized by several techniques including X-ray diffraction, transmission electron microscopy, energy dispersive X-ray anal., electron energy loss spectroscopy, XPS and surface area measurements.  Oxidn. of these copper-based nanoparticles with mol. oxygen and the role of the oxidized layer in the formation of paratacamite have been investigated.  Comparison to microscale copper particles showed there is unique oxidn. behavior of nanoscale copper particles that results in unique reaction chem. of oxidized nanoscale copper particles with hydrochloric acid solns. to form paratacamite.  This study provides a new route for the formation of paratacamite nanomaterials that can be used in a wide range of chem. interesting applications including hydrogen storage materials and as a heterogeneous catalyst for the synthesis of green solvents such as di-Me and di-Et carbonates.  Addnl., this study suggests a potentially new pathway for the degrdn. of art objects and ancient artifacts as well as other cultural heritage materials contg. small copper particles that has not been previously considered.

In particular, carbon black nanoparticles are found in many different environmental exposures.  Macrophages take up inhaled nanoparticles and respond via release of inflammatory mediators and in some cases cell death.  Based on new data, we propose that exposure of macrophages (both a macrophage cell line and primary human alveolar macrophages) to carbon black nanoparticles induces pyroptosis, an inflammasome-dependent form of cell death.  Exposure of macrophages to carbon black nanoparticles resulted in inflammasome activation as defined by cleavage of caspase 1 to its active form and downstream IL-1β release.  The cell death that occurred with carbon black nanoparticle exposure was identified as pyroptosis by the protective effect of a caspase 1 inhibitor and a pyroptosis inhibitor.  These data demonstrate that carbon black nanoparticle exposure activates caspase 1, increases IL-1β release after LPS priming, and induces the proinflammatory cell death, pyroptosis.  The identification of pyroptosis as a cellular response to carbon nanoparticle exposure is novel and relates to environmental and health impacts of carbon-based particulates.

Attempts to modify fluoropolymer surfaces have met with difficulties in that it is difficult to control the modification to maintain bulk characteristics of the polymer.  In a previously described method, the replacement of a small fraction of surface fluorine by acid groups through radio frequency glow discharge created a surface with unexpected reactivity allowing for attachment of proteins in their active states.  The present study demonstrates that 1-ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride (EDC) reacts with the acid groups on fluoropolymer surfaces in a novel reaction not previously described.  This reaction yields an excellent leaving group in which a primary amine on proteins can substitute to form a covalent bond between a protein and these surfaces.  In an earlier study, we demonstrated that collagen IV could be deposited on a modified PTFE surface using EDC as a linker.  Once collagen IV is attached to the surface, it assembles to form a functional stratum resembling collagen IV in native basement membrane.  In this study, we show data suggesting that the fluorine to carbon ratio determines the acidity of the fluoropolymer surfaces and how well collagen IV attaches to and assembles on four different fluoropolymer surfaces.[on SciFinder (R)]</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><notes><style face="normal" font="default" size="100%">MEDLINE AN 2011931130(Journal; Article; (JOURNAL ARTICLE); (RESEARCH SUPPORT, NON-U.S. GOV'T))</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kapadia, Pradeep P.</style></author><author><style face="normal" font="default" size="100%">Ditzler, Lindsay R.</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author><author><style face="normal" font="default" size="100%">Swenson, Dale C.</style></author><author><style face="normal" font="default" size="100%">Tivanski, Alexei V.</style></author><author><style face="normal" font="default" size="100%">Pigge, F.

XPS is used to investigate the surface speciation and surface coverage of sulfur-contg. products on ca. 4 nm TiO2 anatase particles that remain on the surface following adsorption of SO2.  The effects of various environmental conditions of relative humidity, mol. oxygen, and broadband UV/vis irradn. as well as sample pretreatment were found to impact the speciation of adsorbed SO2 as well as the satn. coverage.  In particular, in the absence of light, the majority surface species upon SO2 adsorption is found to be adsorbed sulfite.  Broadband UV/vis irradn. during sulfur dioxide adsorption leads to an increase (nearly 2-fold) in the amt. of adsorbed sulfur species, as compared to expts. with no light, and results in the formation of adsorbed sulfate.  The formation of sulfate was quant. in the presence of mol. oxygen.  New surface species including chemisorbed mol. SO2 were obsd. on samples that have been reduced in vacuum through argon ion sputtering.  The total amt. of adsorbed sulfur was impacted by surface hydroxyl group coverage and molecularly adsorbed water layer.  Addnl., comparison of sulfur dioxide adsorption on 4 vs. 32 nm sized anatase nanoparticles showed that surface satn. coverages of adsorbed sulfite on the 4 nm particles was almost twice that of 32 nm particles as measured by the S2p:Ti2p peak area ratios, thus showing an increase in the inherent adsorption capacity of the smaller particles.  Proposed adsorption sites and mechanisms to account for the obsd. exptl. data are discussed.

These nanomaterials were analyzed with powder x-ray diffraction and attenuated total reflection FTIR spectroscopy.  Sulfur dioxide adsorption on nanoparticles and nanorods of different size was then studied using volumetric measurements, transmission FTIR spectroscopy, and XPS.  Nanoparticles and nanorods of several different sizes were heated to 550° to remove surface-adsorbed org. ligands that remained after the synthesis prior to exposure to SO2.  Spectroscopic anal. revealed the formation of several surface species, including sulfate, sulfite, sulfide, and weakly bound SO2.

It is shown here that H2CO3 formation proceeds via direct CO2 and nH2O reaction with very high activation barriers in the gas phase, 51.40, 29.64, and 19.84 kcal/mol for CO2-H2O, CO2-2H2O, and CO2-3H2O clusters, resp., decreasing in magnitude with an increase in the no. of H2O mols.  The energetics as well as the reaction mechanism and energy landscape change significantly when carbonic acid is formed from CO2 and nH2O in the presence of Al(OH)3, a hydroxylated metal center.

OPF-PPy scaffolds were synthesized using three different anions: naphthalene-2-sulfonic acid sodium salt (NSA), dodecylbenzenesulfonic acid sodium salt (DBSA), and dioctyl sulfosuccinate sodium salt (DOSS).  Scaffolds were characterized by ATR-FTIR, XPS, AFM, dynamic mech. anal., elec. resistivity measurements, and swelling expts.  OPF-PPy scaffolds were shown to consist of up to 25 mol % polypyrrole with a compressive modulus ranging from 265 to 323 kPa and a sheet resistance ranging from 6 to 30 × 103 Ohms/square.  In vitro studies using PC12 cells showed OPF-PPy materials had no cytotoxicity and PC12 cells showed distinctly better cell attachment and an increase in the percent of neurite bearing cells on OPF-PPy materials compared to OPF.  The neurite lengths of PC12 cells were significantly higher on OPF-PPyNSA and OPF-PPyDBSA.  These results show that elec. conductive OPF-PPy hydrogels are promising candidates for future applications in nerve regeneration.

Here we report the synthesis and characterization of PCLF-PPy and in vitro studies showing PCLF-PPy materials support both PC12 cell and dorsal root ganglia (DRG) neurite extension.  PCLF-PPy composite materials were synthesized by polymg. pyrrole in preformed PCLF scaffolds (Mn 7000 or 18,000 g mol-1) resulting in interpenetrating networks of PCLF-PPy.  Chem. compns. and thermal properties were characterized by ATR-FTIR, XPS, DSC, and TGA.  PCLF-PPy materials were synthesized with five different anions (naphthalene-2-sulfonic acid sodium salt (NSA), dodecylbenzenesulfonic acid sodium salt (DBSA), dioctyl sulfosuccinate sodium salt (DOSS), potassium iodide (I), and lysine) to investigate effects on elec. cond. and to optimize chem. compn. for cellular compatibility.  PCLF-PPy materials have variable elec. cond. up to 6 mS cm-1 with bulk compns. ranging from 5 to 13.5 % polypyrrole.  AFM and SEM characterization show microstructures with a root mean squared (RMS) roughness of 1195 nm and nanostructures with RMS roughness of 8 nm.  In vitro studies using PC12 cells and DRG show PCLF-PPy materials synthesized with NSA or DBSA support cell attachment, proliferation, neurite extension, and are promising materials for future studies involving elec. stimulation.

After transferring the CGH by EBL technique an adequate phase profile was obtained.  Inter-level parameter method was developed to obtain the estd. an electron beam dose required for the even topog. patterning.  Using this method, an EBL exposure dose detd. to achieve the required relief amplitude of 1.29 μm was 43 μC/cm2.

The oxidn. of methylene blue, phenol, and methanol was used to evaluate the photoelectrocatalytic activity of the prepd. films.  It has been established that the incident photon-to-current efficiency (IPCE) in 0.1-M K2SO4 decreases as the concn. of methylene blue and phenol increases.

The new phase was analyzed using single-crystal X-ray diffraction and identified as (APAP)·(PDA)·(1).  Structural anal. revealed PDA to exist in a hitherto unreported zwitterionic form in the co-crystal.  A structural anal. of pure PDA revealed the presence of the zwitterion form in (PDA)·(H2O) (2), as well.  The components of 1 self-assemble as a three-dimensional (3D) hydrogen-bonded network with a pronounced 2D structure.

A template-free method to synthesize meso-porous MgO by thermal decompn. of anhyd. magnesium acetate is presented.  Characterization of cryst. phase, particle and pore sizes, and surface area for mesoporous MgO was done using a variety of techniques: SEM, high resoln. transmission electron microscopy, powder x-ray diffraction, and N2 adsorption anal.  Results showed meso-porous MgO synthesized from anhyd. magnesium acetate had a high surface area (120-136 m2/g) and a narrow pore size distribution (3-4 nm).  The pore was comprised of small, primary MgO nano-particle aggregates with inter-particle connections.  In-situ transmission Fourier transform IR spectroscopy assessed CO2 adsorption by meso-porous MgO.  This spectroscopic assessment showed meso-porous MgO exhibited enhanced CO2 adsorption capacity vs. com. available MgO nano-particles.  This difference was mainly attributed to increased surface area.  Differences in surface carbonate/bicarbonate speciation, obsd. between meso-porous and com. MgO, were related to structural differences of the smaller nano-particles.

Force Microscopy (AFM) height images combined with force measurements and phase imaging were used to investigate the surface reconstruction and chem. of the lowest energy surface, ( 1 0 1 4 ) plane, of calcite, a stable form of calcium carbonate (CaCO3), in the presence of relative humidity at different temps.  At 296 K and 70% RH, calcite ( 1 0 1 4 ) undergoes rapid restructuring during hydration forming regions on the surface that are most likely characterized as an amorphous hydrate layer similar to what forms in soln. under high [Ca2+] supersatn. conditions.  This hydrate layer in turn serves as a substrate for the crystn. of another layer that possesses structural properties which differ from hydrate layer.  Phase imaging reveals that these different layer structures formed in the process of water adsorption and surface reconstruction have very different energy dissipation modes.  The origin of the different dissipation modes are likely due to differences in water content and hydrophobicity of these regions.  The newly formed layer on top of the hydration layer is proposed to be vaterite, another polymorph of CaCO3.  At 278 K the formation mechanism of the vaterite layer changes due to nucleation of a more cryst. hydrate layer, similar to CaCO3 hexahydrate, instead of the amorphous hydrate layer that forms at 296 K.  Force measurements corroborate the assignment of the speciation of different regions on the surface.  Importantly, the AFM data show that the surface of calcite is highly inhomogeneous with regions that vary in water content.  The reactivity of calcite in humid environments will be highly spatially dependent.

XPS is used to monitor the different surface species that form under these environmental conditions.  Adsorption of NO2 on aluminum oxide particle surfaces results primarily in the formation of surface nitrate, NO3- with an oxidn. state of +5, as indicated by a peak with binding energy of 407.3 eV in the N1s region.  An addnl. minority species, sensitive to the presence of relative humidity and mol. oxygen, is also obsd. in the N1s region with lower binding energy of 405.9 eV.  This peak is assigned to a surface species in the +4 oxidn. state.  When irradiated with UV light, other species form on the surface.  These surface-bound photochem. products all have lower binding energy, between 400 and 402 eV, indicating reduced nitrogen species in the range of N oxidns. states spanning +1 to -1.  Co-adsorbed water decreases the amt. of these reduced surface-bound products while the presence of mol. oxygen completely suppresses the formation of all reduced nitrogen species on aluminum oxide particle surfaces.  For NO2 on iron oxide particle surfaces, photoredn. is enhanced relative to γ-Al2O3 and surface bound photoreduced species are obsd. under all environmental conditions.  Complementing the exptl. data, N1s core electron binding energies (CEBEs) were calcd. using DFT for a no. of nitrogen-contg. species in the gas phase and adsorbed on an Al8O12 cluster.  A range of CEBEs is calcd. for various nitrogen species in different adsorption modes and oxidn. states.  These calcd. values are discussed in light of the peaks obsd. in the XPS N1s region and the possible species that form following NO2 adsorption and photoreaction on metal oxide particle surfaces under different conditions of relative humidity, presence of mol. oxygen and UV light.

In particular, the uptake of acids such as H2SO4 and HNO3 on mineral dust surfaces can produce extremely acidic environments that promote iron dissoln.  Here, four samples that represent source materials for mineral dust (Saudi Beach sand (SB), Inland Saudi sand (IS), Saharan Sand (SS) and China Loess (CL)) and one com. ref. material (Arizona Test Dust (AZTD)) were characterized, and examd. in dissoln. studies in solns. of sulfuric, nitric and hydrochloric acid ranging from pH 1 to 3.  Mossbauer spectroscopy revealed Fe(III) in all samples, whereas SB, CL and AZTD also contained appreciable Fe(II).  Spectra suggest that both Fe(II) and Fe(III) were substituted into aluminosilicates, although CL, AZTD and IS also contained Fe(III) oxide phases.  Total iron soly. measured after 24 h ranged between 4-16% of the initial iron content for each material, but did not scale with either the sp. surface area or the total iron content of the samples.  Instead, we show that Fe(II)-contg. solid phases such as Fe(II)-substituted aluminosilicates represent a significant, and sometimes dominant, source of sol. Fe in acidic environments.  Results of dissoln. studies also show that the nature of the acid influences iron solubilization, as elevated concns. of nitrate encountered from nitric acid at pH 1 suppressed Fe(II) formation.  We propose a surface-mediated, non-photochem. redox reaction between nitrate and Fe(II), which may contribute to Fe(II)/Fe(III) cycling in the atm.

A custom-designed XPS ultra-high vacuum chamber was coupled to an environmental reaction chamber so that the effects of adsorbed water and mol. oxygen on the reaction of SO2 with iron oxide surfaces could be followed at atmospherically relevant pressures.  In the absence of H2O and O2, exposure of hematite (α-Fe2O3) and goethite (α-FeOOH) to SO2 resulted predominantly in the formation of adsorbed sulfite (SO32-), although evidence for adsorbed sulfate (SO42-) was also found.  At satn., the coverage of adsorbed sulfur species was the same on both α-Fe2O3 and α-FeOOH as detd. from the S2p:Fe2p ratio.  Equivalent satn. coverages and product ratios of sulfite to sulfate were obsd. on these oxide surfaces in the presence of water vapor at pressures between 6 and 18 Torr, corresponding to 28 to 85% relative humidity (RH), suggesting that water had no effect on the adsorption of SO2.  In contrast, mol. oxygen substantially influenced the interactions of SO2 with iron oxide surfaces, albeit to a much larger extent on α-Fe2O3 relative to α-FeOOH.  For α-Fe2O3, adsorption of SO2 in the presence of mol. oxygen resulted in the quant. formation of SO42- with no detectable SO32-.  Furthermore, mol. oxygen significantly enhanced the extent of SO2 uptake on α-Fe2O3, as indicated by the greater than two-fold increase in the S2p:Fe2p ratio.  Although SO2 uptake is still enhanced on α-Fe2O3 in the presence of mol. oxygen and water, the enhancement factor decreases with increasing RH.  In the case of α-FeOOH, there is an increase in the amt. of SO42- in the presence of mol. oxygen, however, the predominant surface species remained SO32- and there is no enhancement in SO2 uptake as measured by the S2p:Fe2p ratio.  A mechanism involving mol. oxygen activation on oxygen vacancy sites is proposed as a possible explanation for the non-photochem. oxidn. of sulfur dioxide on iron oxide surfaces.  The concn. of these sites depends on the exact environmental conditions of RH.

Specifically, when α-Al2O3 and γ-Al2O3 particles are exposed to gas-phase NO2 and HNO3 adsorbed nitrate forms on the surface.  In this study, Fourier transform IR (FTIR) spectroscopy is combined with quantum chem. calcns. to further our understanding of the adsorbed nitrate product on aluminum oxide particle surfaces in the presence and absence of co-adsorbed water at 296 K.  FTIR spectra of adsorbed nitrate on α-Al2O3 and γ-Al2O3 particles are interpreted using calcd. vibrational frequencies of nitrate coordinated to binuclear Al oxide cluster models.  Comparison of the calcd. and exptl. vibrational frequencies of adsorbed nitrate establishes different modes of coordination (monodentate, bidentate and bridging) of the nitrate ion to the surface in the absence of adsorbed water.  In the presence of co-adsorbed water, the nitrate ion becomes fully solvated, as shown by a comparison of the exptl. nitrate IR spectra as a function of relative humidity with the calcd. nitrate vibrational frequencies for binuclear Al cluster compds. which contain both coordinated nitrate ions and water mols.  These calcns. also suggest that adsorbed water can displace nitrate from direct coordination to the surface, leading to an outer-sphere nitrate adsorption complex as well as an inner-sphere complex.  Furthermore, the relative humidity dependence of the spectra suggest that water does not evenly wet the surface even at high relative humidity, as there are open or bare surface sites where nitrate ions are not solvated.  Besides adsorbed monodendate, bidendate, bridging and solvated nitrate, the presence of ion bound nitrate ion, partially solvated nitrate, mol. nitric acid, hydronium ion and H3O+:NO3- ion pairs on the oxide surface are also discussed.

The extent of reaction is significantly enhanced, approx. five- to ten-fold for particulate and single crystal CaCO3 (calcite), resp., in the presence of adsorbed water between 30 and 85% RH.  At. force microscopy following the reaction shows that adsorbed water facilitates surface reactivity by enhancing the mobility of surface ions, giving rise to the formation of nanometer sized product crystallites approx. 1 nm in height.  Simultaneous with the formation of these crystallites is pitting and etching of the underlying substrate, which occurs preferentially in the vicinity of monoat. surface steps.  In the absence of water, there is little pitting and no evidence for the formation of crystallites.  X-Ray photoelectron core and valence band spectra confirm the presence of two sulfur adsorbed species, SO2-3 and SO2-4, with nearly equal amts. of SO2-3 and SO2-4 in the absence of adsorbed water and approx. five times more SO2-3 relative to SO2-4 in the presence of adsorbed water.  From these data, it is proposed that the nanometer-sized crystallites are composed primarily of CaSO3.

AFM images indicate the reaction produces rather well-defined crystallites, preferentially at step edges and at distinct angles to one another and mirroring the rhombohedral structure of the calcite surface, while exposing unreacted carbonate surface.  The size and surface d. of the crystallites depend upon substrate step d., exposure time, and relative humidity.  XPS data confirmed the crystallite compn. as the expected calcium formate product.  The AFM images show erosion and pit formation of the calcite surface in the vicinity of the product crystallites, clearly providing the spatially resolved characterization of the source of Ca ions.  AFM expts. exploring the effects of water vapor on the reacted surface show that the calcium formate crystallites are mobile under conditions of high relative humidity, combining to form larger crystallites and nanometer-sized crystals with an orthorhombohedral habit consistent with the α form, as confirmed by X-ray diffraction.  The implications for the reactions described here are discussed.

NO3- aerosols are present in the earth atm. due to heterogeneous reactions of sea salt and mineral dust aerosol with NOx (e.g., NO2, NO3, HNO3, N2O5).  Since the water content of these aerosols depends on relative humidity (RH), the compn. and NO3- concn. also depends on RH.  Unlike the original aerosols, aq. NO3- aerosols are photochem. active at solar wavelengths.  To better understand the NO3- chromophore in concd. aq. NO3- aerosols, the attenuated total reflection-Fourier transform IR spectroscopic (ATR-FTIR) and UV/VIS spectra of concd. NO3- solns. were measured over a large concn. range.  Both ATR-FTIR and UV/VIS spectroscopy showed changes in NO3- spectra with increasing concn.  Ab-initio calcns. were used to aid in assigning and interpreting these spectra.  From these data, it was predicted that aq. NO3- aerosols photoreactivity will strongly depend on RH since the mol. and electronic structure of NO3- becomes increasingly perturbed from that of the isolated ion in highly concd. atmospherically-relevant solns.

In particular, FTIR spectra following CO2 adsorption in the presence and absence of coadsorbed water on hydroxylated nanoparticulate Fe2O3 and γ-Al2O3 at 296 K are reported.  In the absence of coadsorbed water, CO2 reacts with surface O-H groups to form adsorbed bicarbonate on the surface.  In the presence of coadsorbed water, this reaction is blocked as water hydrogen bonds to the reactive M-OH sites.  Instead, CO2 reacts with adsorbed water to yield adsorbed carbonate and protonated surface hydroxyl groups, M-OH2+, through a proposed carbonic acid intermediate.  The carbonate spectra recorded between 10 and 90% RH are nearly identical to that of carbonate adsorbed on these surfaces in the presence of the liq. water.  FTIR isotope studies show that there is extensive exchange between oxygen in adsorbed water and oxygen atoms in both adsorbed carbonate and gas-phase carbon dioxide.  On the basis of these exptl. results along with quantum chem. calcns., a mechanism is proposed for surface reactions of carbon dioxide at the adsorbed water-oxide interface.

In particular, transmission FTIR spectra following CO2 adsorption on hydroxylated nanoparticulate Fe2O3, α-Al2O3, and γ-Al2O3 particles at 296 K are reported.

In this study, the vibrational spectrum of the bicarbonate product is analyzed in detail through the use of isotope labeling expts. and quantum chem. calcns.  The exptl. and calcd. vibrational frequencies of adsorbed HC16O3-, DC16O3-, HC18O3-, HC16O18O2-, and HC18O16O2- indicate that bicarbonate bonds to the surface in a bridged structure.  There is some evidence from the mixed isotope expts. that following initial nucleophilic attack of OH, the formation of the final bicarbonate structure involves a proton transfer.  On the basis of energetic considerations, the proton transfer mechanism most likely occurs through an intermol. process involving either coadsorbed hydroxyl groups and/or carbonate.

Despite their importance, the process of otoconia genesis is largely unknown.  Reactive oxygen species (ROS) have been recognized for their toxic effects in antimicrobial host defense as well as in aging and carcinogenesis.  Enzymes evolved for ROS prodn. belong to the recently discovered NADPH oxidase (Nox) enzyme family.  Here we show that the inactivation of a regulatory subunit, NADPH oxidase organizer 1 (Noxo1), resulted in the severe balance deficit seen in the spontaneous mutant &quot;head slant&quot; (hslt) mice whose phenotype was rescued by Noxo1 transgenes.  Wild-type Noxo1 was expressed in the vestibular and cochlear epithelia and was required for ROS prodn. by an oxidase complex.  In contrast, the hslt mutation of Noxo1 was biochem. inactive and led to an arrest of otoconia genesis, characterized by a complete lack of calcium carbonate mineralization and an accumulation of otoconial protein, otoconin-90/95 (OC-90/95).  These results suggest that ROS generated by a Noxo1-dependent vestibular oxidase are crit. for otoconia formation and may be required for interactions among otoconial components.  Noxo1 mutants implicate a constructive developmental role for ROS, in contrast to their previously described toxic effects.

FTIR measurements show that the adsorption of formic acid on the surface of calcium carbonate results in the formation of calcium formate.  Besides calcium formate, carbonic acid is also a reaction product under dry conditions (&lt;1% RH).  Under dry conditions and at low pressures, the initial uptake coeff. of formic acid on CaCO3 particles is measured to be 3 ± 1 × 10-3 and decreases as the surface sats. with adsorbed products.  The max. surface coverage of formic acid under dry conditions is detd. to be (3 ± 1) × 1014 mols. cm-2.  Under humidified conditions (RH &gt;10%), adsorbed water on the surface of the carbonate particles participates in the surface reactivity of these particles, which results in the enhanced uptake kinetics and extent of reaction of this org. acid on CaCO3 as well as opens up several new reaction pathways.  These reaction pathways include: (i) the water-assisted dissocn. of carbonic acid to CO2 and H2O and (ii) the formation of calcium formate islands and crystallites, as evident by SEM images.  The results presented here show that adsorbed water plays a potentially important role in the surface chem. of gas-phase org. acids on calcium carbonate particles.

In this study, the chem. of CO2 at the adsorbed water-iron oxide interface was investigated with FTIR spectroscopy.  As shown here, the thin water layer on the iron oxide surface plays an important role in the surface chem. of CO2.  In particular, adsorbed water enhances CO2 uptake, undergoes isotope exchange with CO2 in O(18)-labeled expts., and influences the chem. nature of the predominant adsorbed product on the surface from bicarbonate to carbonate.  The resultant thin water film is acidic in nature from the reaction of CO2.  The IR spectrum recorded of adsorbed carbonate at the adsorbed water-iron oxide interface is remarkably similar to that at the bulk liq. water-iron oxide interface.  Since reactions in thin water films estd. to be ≈2 layers will play a role in a no. of environmental processes, it is essential to understand the chem. of these &quot;wet&quot; interfaces with atm. gases.
