In this work, physicochem. characterization of such composite materials obtained after the exposure of polyamide PA 6 to K2SeS2O6 precursor soln. was performed.  Chalcogenized polymer surface was characterized using X-ray diffraction, IR, and UV-vis spectroscopies while their bulk chem. anal. was performed using at. absorption spectroscopy.  Crystallite size was not found to change with the exposure to K2SeS2O6 precursor but PA 6 chain-chain sepn. decreased.  Importantly, IR and X-ray analyses showed chem. bonding taking place between the PA 6 and SeS2O2-6 ions via -NH- functional group.  A distinct change in bandgap, Eg, value was obsd. in UV-vis spectra due to the presence of SeS2O2-6, SeSO2-3 and Se2S2O2-6 ions formed via decompn. of the precursor material in acidic medium.  After extended 4 h halcogenation a distinct absorption due to the elemental selenium was also obsd. as obtained from Tauc plots. [on SciFinder(R)]},

With the abundance of shale gas, the main concerns have shifted from the limited hydrocarbon availability to the sustainable methods of CH4 conversion to fuels.  This is necessitated by high costs of natural gas transportation in its native gaseous form.  Conventional gas-to-liq. conversion technologies are capital and scale intensive and can hardly be envisioned in their current form to be cost efficient in the remote locations of the natural gas extn. sites.  Solar energy can be utilized at the gas extn. site to perform catalytic CH4 conversion using electrons obtained via photovoltaics or directly with photons.  We provide broader insight into the catalytic CH4 conversion methods that utilize renewable energy via photo(electro)catalytic processes, with particular focus on the catalytic materials used, reaction conditions and intermediates, as well as their selectivity.  Based on the currently available scientific literature, we propose several hybrid catalytic CH4 conversion processes based on both conventional and renewable - photo(electro)chem. - catalysis.

	abstract = {This work investigates water droplet behavior on superhydrophobic (water contact angle value of 162 {\textpm} 1{\textdegree}) SiO2 nanocomposite films subjected to repetitive icing/deicing treatments, changes in SiO2 nanocomposite film surface morphol. and their non-wetting characteristics.  During the expt., water droplets on SiO2 nanocomposite film surface are subjected to a series of icing and deicing cycles in a humid (\~{} 70\% relative humidity) atm. and the resulting morphol. changes are monitored and characterized using at. force microscopy (AFM) and contact angle measurements.  The formation of the frozen or thawed water droplet, with no further shape change, on superhydrophobic SiO2 nanocomposite film, is obtained faster within each cycle as the no. of the icing/deicing cycles increases.  After 10 icing and deicing cycles, the superhydrophobic SiO2 nanocomposite film had a water contact angle value of 146 {\textpm} 2{\textdegree} which is effectively non-superhydrophobic.  AFM anal. showed that the superhydrophobic SiO2 nanocomposite film surface area under the water droplet undergoes gradual mech. damage during the repetitive icing/deicing cycles.  We propose a possible mechanism of the morphol. changes to the film surface that take place during the consecutive icing/deicing expts. [on SciFinder(R)]},

	abstract = {Cr thin films were deposited on float glass using electron beam (e-beam) phys. vapor deposition and radio frequency (RF) magnetron sputtering techniques.  Surface morphol. of these Cr films was studied using AFM.  The e-beam deposited Cr films consisted of isolated surface mounds while in RF sputtered samples, these mounds combined to form larger islands.  However surface adhesive properties were obsd. for e-beam deposited films, as detd. from AFM force-distance curves, presumably due to the nanostructural differences.  Similar amts. of adsorbed atm. carbonaceous contaminants and water vapor were detected on samples deposited using both methods with e-beam deposited samples having addnl. carbide species, as detd. by XPS data.  The dominant crystallog. plane in both e-beam deposited and RF sputtered Cr thin films was (110) of body-centered cubic Cr metal structure as detd. from x-ray diffraction data.  Weak (211) reflection was also obsd. in RF sputtered samples and was attributed to a different thin Cr film condensation and growth mechanism which resulted in nanostructural differences between films deposited using two different methods.

In this work, fabrication process of the silicon nanopillar structures is described.

SEM and XPS were used to characterize self-organized gold and chromium clusters as well as the final silicon nanopillars.

Scaffolds were electrically conductive with resistivity as low as 2Ω.  Scaffold characterization by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and thermo gravimetric analysis shows both polypyrrole and hydroxyapatite are present.  Cell viability, attachment, proliferation, and differentiation were analyzed using human fetal osteoblast cells.  These studies show that surface modification using hydroxyapatite improved cell attachment and proliferation of osteoblasts onto the PPF scaffolds.  Alkaline phosphatase activity as a marker for osteogenic differentiation of cell to mature osteoblasts was analyzed.  Our data reveal that osteoblasts maintained their phenotype on PPF scaffolds with and without coatings.  Thus, these scaffolds could be appropriate candidates for our future in vivo studies.[on SciFinder (R)]},

The deposition transients analyzed in the non-dimensional plots I2/I2m = f(t/tm) and I2/I2m = f(t/tm)2 have shown that MoOx nucleates according to a progressive mechanism.

Deposition conditions were adjusted by varying substrate temp. and SiH4:NH3 flow ratio and temp. to obtain the required stress related and elec. properties of the membranes.  Transmission FTIR spectroscopy and SEM were used to investigate the chem. compn. and morphol. of the stacked film components.  An increase in the SiH4:NH3 flow ratio and a decrease in temp. resulted in a silicon-rich silicon nitride film, as well as an increased silicon oxide concn.  To avoid under-etch and sidewall defects, the plasma power d. during the plasma etching was changed from 0.5 W/cm2 during the etching of both top and bottom layers in a stacked film, to 1.0 W/cm2 during the etching of the middle both silicon and silicon oxide-rich film.  This resulted in an improved overall stacked film sidewall quality and reduced the unwanted under-etch. [on SciFinder(R)]},

This method differs from previous thin film cond. measurement methods by the absence of an external power source.  Instead, it employs natural charges carried by ions and electrons that are present in a vapor that is deposited.  The ability to monitor thin film cond., starting with early nucleation stages up to the formation of the integrally conductive film is shown by a comparison of in-situ recorded voltage changes and ex-situ by XPS and at. force microscopy anal. of the stepwise covered samples.  Repeatability of the exptl. data was within a {\textpm} 25\% interval at the exptl. parameter region where an integrally conductive film starts to form. [on SciFinder(R)]},
