An organic/inorganic bistable device is fabricated by using a simple spin-coating technique, in which the hybrid silver sulfide (Ag2S) poly(N-vinylcarbazole) (PVK) nanocomposite film is sandwiched between two electrodes. An obvious electrical hysteresis is observed in the current-voltage (I-V) curve of the device measured in the presence of different oxygen concentrations, and the magnitude of ...

The electronic structures of four semiconductor compounds BaCu2S2, BaCu2Se2, BaAg2S2, and BaAg2Se2 are studied by density functional theory using both semi-local and hybrid functionals. The ionization energies and electron affinities were determined by aligning the electronic states with the vacuum level by calculating the electrostatic profile within a supercell slab model. The ionization ener...

Hexa-methyl-phospho-ramide (hmp), tetra-thio-tungstate, silver sulfide and dysprosium nitrate were self-assembled, forming an anionic [AgWS(4)](n) (n) (-) chain in the title compound, {[Dy(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The central Dy atom in the cation is coordinated by eight O atoms from two didentate nitrate and four hmp ligands, giving rise to a distorted square anti-prismatic...

Combined with real-time monitoring of density and temperature, the control redox potential provides a new approach to influencing cell metabolism during growth, viability non-growing yeast activity in wine fermentations. Prior research indicates that problem sluggish incomplete fermentation can be alleviated by maintaining constant ethanol fermentation. A secondary trait hydrogen sulfide format...

This analysis explores the theory and design of dielectric multilayer reflection-enhancing thin film stacks based on high and low refractive index alternating layers of cadmium sulfide (CdS) and lead sulfide (PbS) on silver (Ag)-coated hollow glass waveguides (HGWs) for low loss transmission at midinfrared wavelengths. The fundamentals for determining propagation losses in such multilayer thin-...

Even though it is a noble metal, silver will corrode in ambient atmospheres, predominantly by reacting with sulfur-containing gases such as hydrogen sulfide (H2S) and carbonyl (OCS) to form the (Ag2S) acanthite. Other aspects of environment, relative humidity presence oxidizing species, also play critical role. With emergence nanoparticles for range technological medical applications, there has...

The electrical contact resistance of a Ag/carbon nanotube (CNT) composite plating film prepared using cyanide-free bath was evaluated against H2S gas corrosion test. After the test, Ag/CNT exhibited lower than Ag for comparison. mechanism superior characteristics investigated various methods. Scanning electron microscopy observations and X-ray diffraction analyses revealed that amount silver su...
