Functional Theory calcns. and explored reactive pathways of ethanol catalysis to catalytically form 1,3-butadiene on undoped MgO surface.  We have identified crit. reactive intermediates, as well as thermodn. and kinetic barriers involved in the overall reactive landscape.  The overall free energy surface was explored for the highly debated reaction mechanisms, including Toussaint's aldol condensation mechanism, Fripiat's Prins mechanism and mechanism based on Ostromislensky's hemiacetal rearrangement.  Thermodn. and kinetics data calcd. showed four rate limiting steps in the overall process.  In particular, ethanol dehydration to form ethylene possessed lower energy barrier than dehydrogenation to yield acetaldehyde suggesting competing reactive pathways.  C-C bond coupling to form acetaldol (3-hydroxybutanal) is preceded with 16 kcal/mol forward reaction barrier.  Direct reaction of ethylene and acetaldehyde proceeds with a free energy barrier of 29 kcal/mol suggesting that Prins condensation is an alternative route.  Finally, thermodn. stability of 1-ethoxyethanol prevents further reaction via hemiacetal rearrangement.  The results here provide a first glimpse into the overall 1,3-butadiene formation mechanism on undoped MgO reactive sites in light of the vast literature discussing variety of the proposed mechanistic pathways mostly based on conventional homogenous org. chem. reactions.

Natural gas is envisioned as a primary source of energy and hydrocarbons in the foreseeable future.  Though shale gas has recently become abundant, it has two main concerns: its environmental impact and sustainable utilization.  The former is the result of recent reports of natural gas emissions and flares into the environment, where it acts as a powerful greenhouse gas, whereas the latter is dictated by the need for efficient hydrocarbon utilization.  Modern natural gas processing units that yield clean fuels and feedstock from methane, CH4, require extremely large capital investments and are not economical in remote natural gas extn. sites.  Single step (direct), non-syngas based catalytic routes of CH4 conversion to value added products have not been competitive economically and need to be reevaluated in the light of shale gas availability.  This perspective discusses general considerations for the desired hydrocarbon products, the thermodn. limitations involved in a single step conversion of CH4 and heterogeneous catalytic routes based on high temps. and oxide based catalysts.  We then discuss other catalysts and methods of CH4 activation that have recently emerged and are conceptually different from metal oxide catalyst based routes, such as those using sulfur or halogens.  Lastly, we discuss a possible route of CH4 monetization beyond the first reactive product (such as ethylene oligomerization into fuels), as well as currently explored photo(electro)chem. routes of CH4 activation.

The developed synthesis procedure involved heating at mild 55 °C temp., followed by pH adjustment to 7, pptn., and drying.  The resulting solid materials were characterized using wt. anal., thermogravimetric anal. (TGA), X-ray diffraction (XRD), and Fourier transformed IR spectroscopy (FTIR).  Higher wastewater-to-zinc nitrate ratios of 1:1/5 yielded amorphous materials with no inorg. zinc compds. detected.  TGA anal. showed very complex thermal behavior due to the large amt. of orgs. present while FTIR anal. suggested the presence of both coordinated and uncoordinated carboxylic acid and ester groups.  The developed process can have a variety of applications in recovering Zn from waste sources, such as tire crumb, while returning this valuable micronutrient into soil as a slow release biodegradable fertilizer.

We investigated the effects of moisture content in the manure, energy consumption during the three main stages of the process and the possibility to obtain nutrient balanced fertilizers using conventional straw drying and granulation equipment, common on the farms.  Poultry manure was dried and shredded to no less than 90% of dry mass at 95 °C.  Granulation was performed via extrusion with and without mineral additives, such as diammonium phosphate (DAP) and potassium chloride (KCl).  This process was used to achieve 4-3-3 OGF, as well as tunable NPK content (4-4-2, 4-3-6 and 4-4-9) OMF.  Energy consumption as the manure dried was about 100 kWh/t of product.  This limiting step of the process suggests that the max. achievable drying of sub 10% water currently commonly used is not necessarily economically optimal.  DAP was used to increase water-sol. phosphate concn. and was limited to 6% of the total amt. by the emission of ammonia during the granulation process.  Addnl., the presence of hygroscopic KCl in combination with DAP resulted in significant moisture absorption and loss of the granulized pellet structural integrity after 72 h at 30 °C and 80% RH.  Significant increases in yields of rapeseed and potato crops were obsd. with the 2 t/ha application of OGF or DAP/KCl enhanced OMF.  The engineered process will provide for sustainable prodn. of nutrient balanced organo-mineral fertilizers on the manure prodn. sites using conventional equipment already used for straw processing.

XRD data indicated complex compns. of the mineral additives DAP and KCl, while OGF and OMF exhibited amorphous backgrounds with small peaks due to the common Earth crust minerals (Si, Mg, Zn, Ca).  Addn. of DAP generated several new chem. compds., while KCl did not react.  Thermogravimetric anal. indirectly showed mineral-mineral interactions at high temps., as can be inferred from their 478 °C peak shift.  Spatially resolved SEM-EDS anal. showed a particularly interesting colocalization of potassium, sulfur, and phosphorus within the OMF, suggesting a reactive salt interaction between DAP and minerals inherently present in OGF.  FTIR anal., on the other hand, did not show significant involvement of org. moieties with the interactions of mineral additives, suggesting org. compds. act mostly as inert support for DAP and KCl.  Collectively, these data suggest a complex nature of the OGF and OMF at the mol. and cryst. levels, which improves our understanding of these complex systems with direct relevance to sustainable nutrient management.

It includes relevant fundamentals pertaining to the topics covered in that earlier review, such as conventional metal and metal oxide surfaces and CO2 interactions thereon.  While UHV spectroscopy has routinely been applied for CO2 gas-solid interface anal., the present work goes further by describing surface-CO2 interactions under elevated CO2 pressure on non-oxide surfaces, such as zeolites, sulfides, carbides and nitrides.  Furthermore, it describes addnl. salient in situ techniques relevant to the resoln. of the interfacial chem. of CO2, notably IR spectroscopy and state-of-the-art theor. methods, currently used in the resoln. of solid and sol. carbonate species in liq.-water vapor, liq.-solid and liq.-liq. interfaces.  These techniques are directly relevant to fundamental, natural and technol. settings, such as heterogeneous and environmental catalysis and CO2 sequestration.

(i.e., its concn. in the gas phase), ranged between 0.39 and 1.52 mg L-1 when varying the discharge power between 5-33 W.  The decompn. efficiency of 2-naphthol reached 98.6% in 6 min at 33 W based on HPLC measurements.  FTIR and GC/MS analyses revealed that degrdn. intermediates consisted mostly of oxygen functional group contg. compds., such as carboxylic acids.

Sn and S precursors and conditions optimized to maximize its performance as a photoelectrode.  Films composed of primarily orthorhombic SnS were electrodeposited on titanium substrates from electrolyte contg. 20 mM SnSO4 and 100 mM Na2S2O3 at pH 2.5.  For deposition a cathodic pulse of -1.25 V vs Ag/AgCl was applied for 2.75 s followed by a 0.25 s pulse of +0.25 V vs Ag/AgCl repeated for 30-45 min.  The films were annealed in argon at 300 °C for 3 h.  The addn. of SbCl3 (&lt;5%) to the electrolyte gave rise to doping of the SnS film with Sb which resulted in an increase in the photocurrent as well as a switch from p- to n-type semiconducting behavior in an acidified Na2S2O3 electrolyte.  Incorporation of p-type In into the films from addn. of In(NO3)3 had a smaller effect on the measured photocurrent, and at higher precursor concn. (&gt;5%) the dopants resulted in the formation of secondary phases of Sb and In oxides with redn. in the measured photocurrent.  This doped SnS material could potentially be used in systems for the photoelectrochem. prodn. of hydrogen and oxidn. of org. wastewater.  D. functional theory calcns. supported the exptl. obsd. cond. increase for photoelectrons as an Sb dopant induced curvature of the valence band.  These calcns. also provided an explanation to the previous exptl. work where Sb doping was used to decrease the resistivity of SnS films.  The combination of an automated electrodeposition of an earth abundant metal sulfide with the theor. calcns. to guide the synthesis is an exemplar of how to improve the efficiency of SnS-based solar energy conversion materials.

The presence of oxygen vacancies in the hematite surface resulted in pronounced shifts of the onset potential to 3.09 V and 1.83 V, resp.

Polyethylene was used as a model org. host material for thin copper sulfide film formation.  Adsorption-diffusion method was used which utilized consecutive exposure of polyethylene to polythionic acid followed by aq. Cu(II/I) soln.  Several cryst. copper sulfide phases were obtained in synthesized samples and elucidated using X-ray diffraction.  Surface chem. compn. detd. using XPS showed the presence of copper sulfides in combination with copper hydroxide.  Thickness of the composite material films ranged from several microns to ∼18 μm and depended on the Cu(II/I) exposure time.  Band gap of the materials obtained was measured and ranged from 1.88 to 1.17 eV.  Importantly, heating these complex copper sulfide cryst. phase contg. films at 100 °C in inert atm. invariably resulted in a single copper sulfide, anilite (Cu1.75S), phase.  Anilite possesses a bandgap of 1.36 eV and has demonstrated excellent photovoltaic properties.  Thus, the method described in this work can be used for a low cost large scale composite thin film photovoltaic material deposition based on anilite as photoactive material.

Ag2S composite materials were synthesized on oxidized polypropylene using chem. bath deposition method and their properties were explored using XRD, XPS, AFM and UV-Vis.  Polypropylene surfaces were modified using soln. methods to introduce hydrophilicity via carboxylic group formation which resulted in Ag2S film deposition and adhesion.  These films showed slightly sulfur enriched compn. from XPS anal. with the sulfate-like species forming, presumably at the oxidized polymer surface sites.  Ag2S particle growth mechanism included nucleation and rather large (few μm) aggregate formation eventually covering the complete polymer surface, as inferred from AFM anal.  Absorption edge of the composite material shifted toward the higher wavelength in UV-Vis spectrum with the no. of Ag2S exposure times showing a decreasing bandgap and the possibility of obtaining tunable optical property Ag2S-polymer composites using CBD methods.

The exptl. design model of each PA nanofibers contained the following variables: polymer concn., ratio of solvents, nanofiber media collection time, tip-to-collector distance, and the deposition voltage.  The av. diam. of the fibers, their morphol., basis wt., thickness, and resulting media solidity were investigated.  Effects of each variable on the essential characteristics of PA 6/6 and PA 6 nanofiber media were studied.  The comparative anal. of the obtained PA 6/6 and PA 6 nanofiber characteristics revealed that PA 6/6 had higher potential to be used in filtration applications.  Based on the exptl. results, the graphical representation-response surfaces-for obtaining nanofiber media with the desirable fiber diam. and basis wt. characteristics were derived.  Based on the modeling results the nanofiber filter media (mats) were fabricated.  Filtration results revealed that nanofiber filter media electrospun from PA6/6 8% (w/vol) solns. with the smallest fiber diams.

Cuprous oxide films with [100], [110] and [111] orientation and variable thickness were electrodeposited by redn. of copper(II) lactate on com. available copper plates.  After initiation of the electrochem. CO2 redn. by these oxide structures, the selectivity of the process largely depends on the parent Cu2O film thickness, rather than on the initial crystal orientation.  Starting with thin Cu2O films, besides CO and hydrogen, selective formation of ethylene is obsd. with very high ethylene-to-methane ratios (∼8 to 12).  In addn. to these products, thicker Cu2O films yield a remarkably large amt. of ethane.  Long term faradaic efficiency anal. of hydrocarbons shows no sign of deactivation of the electrodes after 5 h of continuous expt.  Online mass spectroscopy studies combined with x-ray diffraction data suggest the redn. of the Cu2O films in the presence of CO2, generating a nanoparticulate Cu morphol., prior to the prodn. of hydrogen, CO, and hydrocarbons.  Optimizing coverage, no. d. and size of the copper nanoparticles, as well as local surface pH, may allow highly selective formation of the industrially important product ethylene.

In this work, TlSe composite materials were synthesized on a model polymer polyamide using temp. and pH controlled adsorption-diffusion method via selenization followed by the exposure to the group III metal (Tl) salt soln. and their surface morphol., chem. and cryst. phase information was detd. with particular focus on their corresponding structure-optical property relationship.  XRD anal. yielded a complex cryst. phase distribution which correlated well with the optical and surface morphol. properties measured. pH 11.3 and 80° yielded well defined, low structural disorder composite material surface.  After annealing in N2 at 100°, polycryst. PA-TlxSey composite materials yielded a single TlSe phase due to the enhanced diffusion and reaction of thallium ions into the polymer.  The method described here can be used to synthesize variety of binary III-VI compds. diffused into the polymer at relatively low temps. and low overall cost, thus providing for a flexible synthesis route for novel composite solar energy harvesting materials.

The work described here uses exptl. water adsorption measurements on Na-montmorillonite and illite clay to det. empirical adsorption parameters that can be used in a recently derived theor. framework (Frenkel-Halsey-Hill Activation Theory, FHH-AT) that accounts for the effect of water adsorption on CCN activation.  Upon fitting the Frenkel-Halsey-Hill (FHH) adsorption model to water adsorption measurements, we find FHH adsorption parameters, A and B, to be 98 ± 22 and 1.79 ± 0.11 for montmorillonite and 75 ± 17 and 1.77 ± 0.11 for illite, resp.  The A and B values obtained from water adsorption measurements differ from values reported previously detd. by applying FHH-AT to CCN activation measurements.  Differences in FHH adsorption parameters were attributed to different methods used to obtain them and the hydratable nature of the clays.  FHH adsorption parameters detd. from water adsorption measurements were then used to calc. the crit. super-satn. (s) for CCN activation using FHH-AT.  The relationship between s and the dry particle diam. (D) gave CCN activation curve exponents (x) of -0.61 and -0.64 for montmorillonite and illite, resp.  The x values were slightly lower than reported previously for mineral aerosol.  The lower exponent suggests that the CCN activity of hydratable clays is less sensitive to changes in D and the hygroscopicity parameter exhibits a broader variability with D compared to more sol. aerosols.  Despite the differences in A, B and x, the FHH-AT derived CCN activities of montmorillonite and illite are quite similar to each other and in excellent agreement with exptl. CCN measurements resulting from wet-generated clay aerosol.  This study illustrates that FHH-AT using adsorption parameters constrained by water adsorption is a simple, valid method for predicting CCN activation of fresh clay minerals and provides parameters that can be used in atm. models to study the effect of mineral dust aerosol on cloud formation and climate.

Hydrolysis of each phosphate salt gave a specific pH that affected the purity and morphol. of the prepd. Ag3PO4.  The Ag3PO4 prepd. from Na2HPO4 showed the best photocatalytic activity induced by visible light to degrade methylene blue dye.  During the photocatalytic process, Ag3PO4 decompd. and produced metallic Ag, and this evidence was confirmed by the X-ray diffraction technique and XPS.  The photocatalytic efficiency decreased with the no. of recycles used.  This Ag3PO4 photocatalyst also degraded another cationic dye, rhodamine B, but did not degrade reactive orange, an anionic dye.  The degraded products produced by the photocatalysis had lower toxicities than the untreated dyes using Chlorella vulgaris as a bioindicator.

As an inherently stable compd., SnS surfaces are expected to be hydrophobic by nature.  However, exposure of pristine SnS surfaces to air inevitably leads to surface oxidn. which can affect the mineral's dissoln., reactivity, optical and electronic properties as well as hydrophobicity.  In the present study, water adsorption measurements on oxidized SnS thin films were performed using horizontal attenuated total reflection Fourier transform IR (HATR-FTIR) spectroscopy.  XPS anal. allowed for characterization of the SnS surface compn. before water vapor exposure and identification of any changes that occurred to the surface after water vapor exposure.  XPS results are consistent with water adsorption occurring on SnS surfaces contg. hydroxyl and carbonate groups.  Addnl., XPS anal. showed that exposure of SnS to water vapor resulted in no significant changes to the original surface compn.  Quant. water adsorption measurements using HATR-FTIR spectroscopy show that the oxidized SnS surface exhibits a slightly hydrophilic nature, demonstrating multilayer water adsorption at high relative humidity (RH) values.  Exptl. water adsorption data were fit using the Brunauer-Emmett-Teller (BET) and Freundlich adsorption models.  From these model fits, details of monolayer water adsorption and the water adsorption mechanisms were extd. to provide a better understanding of gas/surface adsorption on oxidized SnS surfaces.  Results suggest that water adsorption on SnS powder occurs in three distinct regimes, including sub-monolayer water adsorption up to monolayer coverage at 13% RH, followed by filling of mesopores (13-76% RH) and finally multilayer water adsorption ( &gt; 76% RH) via filling of macropores.  This study represents the first report of in situ water adsorption measurements on SnS as a function of relative humidity, illustrating how oxidized surface species can alter the hydrophobic nature of SnS surfaces.

Quantum entangled energy transitions from one subsystem to the other and the assembly of logically controlled artificial minimal protocells were modeled.  The systems studied were based on different photoactive sensitizer mols. covalently bonded to a non-canonical oxo-guanine::cytosine supramol. with the precursor of a fatty acid (pFA) mol. attached via Van der Waals forces, all surrounded by water mols.  The electron correlation interactions responsible for the weak hydrogen and Van der Waals chem. bonds increased due to the addn. of polar water solvent mols.  The distances between the sepd. sensitizer, nucleotide, pFA, and water mols. are comparable to Van der Waals and hydrogen bonding radii.  As a result, the overall system becomes compressed, resulting in photo-excited electron tunneling from the sensitizer (bis(4-diphenylamine-2-phenyl)-squarine or 1,4-bis(N,N-dimethylamino)naphthalene) to the pFA mols.  Absorption spectra as well as electron transfer trajectories assocd. with the different excited states were calcd. using time dependent d. functional theory methods.  The results allow sepn. of the quantum entangled photosynthetic transitions within the same minimal protocell and with the neighboring minimal protocell.  The transferred electron is used to cleave a &quot;waste&quot; org. mol. resulting in the formation of the desired product.  A two variable, quantum entangled AND logic gate was proposed, consisting of two input photoactive sensitizer mols. and one output (pFA mol.).  It is proposed that a similar process might be applied for the destruction of tumor cancer cells or to yield building blocks in artificial cells.

Ag-doped ZnO powders were prepd. directly from an aq. soln. of zinc acetate dihydrate and AgNO3 in the presence of poly(ethylene oxide)-b-poly(propylene oxide), (PEO)19-b-(PPO)3, and NaOH at 70°.  The ZnO powders had an urchin-like shape without any dopant and this turned to an agglomerated rod-like structure when the Ag loading was ≤0.5 mol%.  If the Ag content was further increased, the urchin-like shape reappeared.  This may occur because the Ag aggregates at the grain boundary.  The finding that the diam. of the urchin-like shape decreases as the Ag concns. increase, can be explained by the pinning effect of the Ag particles as obstacles that inhibit the grain migration and grain growth.  An increase of the photocatalytic efficiency for degrading methylene blue increases with the Ag loading up to 1.0 mol% while the best of the antibacterial activity against Staphylococcus aureus was found at 0.5-0.8 mol% of Ag.  However, the different Ag loadings in the ZnO powders had no effect on the antibacterial effect on Escherichia coli.

The water content as a function of RH was modeled using the Brunauer, Emmett, and Teller (BET) and Freundlich adsorption isotherm models to provide complementary multilayer adsorption anal. of water uptake on the clays.  A detailed anal. of model fit integrity is reported.  From the BET fit to the exptl. data, the water content on each of the three clays at monolayer (ML) water coverage was detd. and found to agree with previously reported gravimetric data.  However, BET anal. failed to adequately describe adsorption phenomena at RH values &gt;80%, 50%, and 70% RH for kaolinite, illite, and montmorillonite clays, resp.  The Freundlich adsorption model was found to fit the data well over the entire range of RH values studied and revealed two distinct water adsorption regimes.  Data obtained from the Freundlich model showed that montmorillonite has the highest water adsorption strength and highest adsorption capacity at RH values &gt;19% (i.e., above ML water adsorption) relative to the kaolinite and illite clays.  The difference in the obsd. water adsorption behavior between the three clays was attributed to different water uptake mechanisms based on a distribution of available adsorption sites.  Probably different properties drive water adsorption under different adsorption regimes resulting in the broad variability of water uptake mechanisms.
