	abstract = {In this work, we performed periodic D. 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{\textquoteright}s aldol condensation mechanism, Fripiat{\textquoteright}s Prins mechanism and mechanism based on Ostromislensky{\textquoteright}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.

	abstract = {A review.  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.

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 {\textdegree}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 {\textdegree}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.

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.

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 {\textdegree}C for 3 h.  The addn. of SbCl3 (<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. (>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.

	abstract = {Fresh mineral aerosol has recently been found to be effective cloud condensation nuclei (CCN) and contribute to the no. of cloud droplets in the atm. due to the effect of water adsorption on CCN activation.  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 {\textpm} 22 and 1.79 {\textpm} 0.11 for montmorillonite and 75 {\textpm} 17 and 1.77 {\textpm} 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.

	abstract = {Tin(II) sulfide (SnS) is considered to be a promising optoelectronic material due to its narrow band gap, strong optical absorption, low cost and nontoxic and chem. inert characteristics.  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{\textquoteright}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 ( > 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.

	abstract = {The quantum mech. self-assembly of two sep. photoactive supramol. systems with different photosynthetic centers was investigated by means of d. functional theory methods.  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 "waste" 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. [on SciFinder(R)]},

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.

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.
