Two-dimensional Bi₂Se₃ nanosheets with hexagonal shape are synthesized by a solution synthetic route. The Bi₂Se₃ nanosheets are 120 nm in edge width and 7 nm in thickness. The size of the Bi₂Se₃ nanosheets can be controlled by choosing different kinds of reducing agents including hydroxylamine and ethylenediamine. Subsequently, we demonstrate a configuration of two-color all-optical switching b...

A number of nitrones have been synthesized in three different procedures, starting with N-phenyl hydroxylamine, followed by the condensation reaction some selected aldehydes. Furthermore, these were employed preparation a new isoxazolidines. Cycloaddition to styrene produced desired products.

An optimized and validated spectrophotometric method has been developed for the determination of Tetracycline hydrochloride (TCH) in pharmaceutical formulations. The method is based on the reaction between TCH, sodium nitroprusside and hydroxylamine hydrochloride in alkaline medium. The product absorbed maximally at 529 nm. Beer’s law is obeyed in the working concentration range of 2-60 μg mL w...

With this research, we have developed a bodipy based system as the first "turn-on" fluorescence system for the detection hydroxylamine.

Hydroxytriazenes behave like bidentate ligands which have alpha hydroxyl group relative to azo group. The synthesis includes reduction of an alkyl or aryl nitro compound in neutral medium to get hydroxylamine and diazotization of an aromatic amine to get diazonium chloride. When these two that is hydroxylamine and respective diazonium salt are coupled we get hydroxytriazene as a product. A gene...

A reduced nicotinamide adenine dinucleotide phosphate (NADPH)-specific enzyme from Escherichiu wti, isolated as a nitrite reductase, catalyzed the reductions of both nitrite and hydroxylamine to ammonia, and the ratio of the two activities remained constant during partial purification (1). The demonstration in the same species of an NADPH-specific enzyme catalyzing the reductions of hydroxylami...

Resting cells of Corynebacterium nephridii reduce nitrate, nitrite, and nitric oxide to nitrous oxide under anaerobic conditions. Nitrous oxide production from nitrite was optimal from pH 7.0 to 7.4. The stoichiometry of nitrous oxide production from nitrite was 99% of the theoretical-two moles of nitrite was used for each mole of nitrous oxide detected. Hydroxylamine increases gas evolution fr...
