Red single crystals of AgTl3(Cr2O7)2 were prepared via high oxygen pressure synthesis as well as by hydrothermal autoclave techniques. Initially, AgTl3(Cr2O7)2 was obtained from a reaction of stoichiometric mixtures of Ag2O, Cr and TlNO3 under elevated oxygen pressures. Following an optimized approach, the title compound can be synthesized at mild hydrothermal conditions, starting from AgNO3, T...

UV–VIS spectroscopy is applied to study the structural and especially morphological particularities of silver nanoclusters-phosphate glass composites from the dispersed phase perspective. The electronic absorption measurements performed on several types of phosphate glasses with different Ag2O content indicate the existence of both silver nanoparticles of various dimensions and shapes, and Ag i...

A green chemistry-based highly regioselective synthesis of ethyl (9-anthryl)glyoxylate was achieved by solvent-free Friedel-Crafts reaction at r. t. Several derivatives of ethyl (9-anthryl)glyoxylate were also synthesized. Ethyl (9-anthryl)hydroxyacetate was obtained almost quantitatively by reduction of ethyl (9-anthryl)glyoxylate with NaBH4, and (9-anthryl)methoxyacetic acid was prepared by m...

The primary goal of this study is to investigate the effect different exchange-correlation functionals on optoelectronic and elastic properties Ag2O chalcogenide compound. For electronic structures optical spectra, Tran-Blaha modified Becke-Johnson approach combined with GGA GGA+U (mBJ-GGA-PBEsol mBJ-GGA-PBEsol+U, respectively) was used. available theoretical experimental data for bandgap energ...

The corrosion of Ag in an atmosphere of ozone and humidity with or without irradiation by ultraviolet (UV) light was investigated. A modified coulometric reduction technique was used, substituting sulphate solution for chloride solution, to prevent the spontaneous transformation of silver oxide corrosion product to chloride in the reduction solution. The presence of both ozone and UV radiation ...
