Xerogel-sequestered silanated organochalcogenide catalysts for bromination with hydrogen peroxide and sodium bromide.
While H2O2 is a powerful oxidant, decomposing into environmentally benign H2O and O2, a catalyst is often required for reactions with H2O2 to proceed at synthetically useful rates. Organotellurium and organoselenium compounds catalyze the oxidation of halide salts to hypohalous acids using H2O2. When sequestered into xerogel monoliths, the xerogel-chalcogenide combinations have demonstrated inc...
متن کاملEvaluation of yeast isolated from industrial waste to remove selenium and the use of biomass in livestock and poultry food
Background: Bioavailability is a good alternative to conventional physical and chemical methods for removing toxic metals from groundwater and wastewater. Methods: In this research, phenotypic and genotypic study was carried out on the use of isolated yeast from industrial effluents with the aim of eliminating Selenium biological and the production of biomass as a feed for livestock and poult...
متن کاملUltrathin inorganic molecular nanowire based on polyoxometalates
The development of metal oxide-based molecular wires is important for fundamental research and potential practical applications. However, examples of these materials are rare. Here we report an all-inorganic transition metal oxide molecular wire prepared by disassembly of larger crystals. The wires are comprised of molybdenum(VI) with either tellurium(IV) or selenium(IV): {(NH4)2[XMo6O21]}n (X=...
متن کاملIn-situ X-ray photoelectron spectroscopy study of the oxidation of CuGaSe2
The thermal and native oxidation of CuGaSe2 thin films was studied by in-situ X-ray photoelectron spectroscopy (XPS). The special design of the XPS chamber allowed to measure XP-spectra under oxidizing gas atmospheres at pressures of up to 5mbar (in-situ) or in ultra high vacuum (UHV). During thermal oxidation, the formation of predominantly Ga2O3 and some amount of SeO2 were observed, but no c...
متن کاملEffects of selenium compounds on phospholipid/Ca2+-dependent protein kinase (protein kinase C) system from human leukemic cells.
Selenium compounds (selenium dioxide, selenious acid, and selenic acid) were found to inhibit phospholipid/Ca2+-dependent protein kinase (protein kinase C) and the phorbol ester-stimulated phosphorylation of endogenous substrate proteins from HL60 cells. Kinetic analysis indicated that selenium dioxide (SeO2) inhibited the enzyme noncompetitively with respect to phosphatidylserine (apparent Ki,...
