A Biosensor for Detect Nitrite (NO2-) and Hydroxylamine (NH2OH) by Using of Hydroxylamine Oxidase and Modified Electrode with ZnO Nanoparticles

International Journal of Electrochemical Science, 2013
The direct electrochemistry of Hydroxylamine oxidase (HAO) / zinc oxide (Zno) nanoparticles (Nps) /carbon paste electrode (CPE) was studied for design a new biosensor for detect Nitrite (NO2-) and hydroxylamine (NH2OH).

Primary fibroblasts from CSPα mutation carriers recapitulate hallmarks of the adult onset neuronal ceroid lipofuscinosis [PDF]

, 2017
Mutations in the co- chaperone protein, CSPα, cause an autosomal dominant, adult-neuronal ceroid lipofuscinosis (AD-ANCL). The current understanding of CSPα function exclusively at the synapse fails to explain the autophagy-lysosome pathway (ALP ...

A mathematical model of bacteria capable of complete oxidation of ammonium predicts improved nitrogen removal and reduced production of nitrous oxide [PDF]

, 2017
The removal of excess nutrients from water ecosystems requires oxidation of toxic ammonium by two types of bacteria; one oxidizes ammonium to nitrite and the other oxidizes nitrite to nitrate.

Crown-hydroxylamines are pH-dependent chelating N,O-ligands with a potential for aerobic oxidation catalysis

Nature Communications, 2023
Despite the rich coordination chemistry, hydroxylamines are rarely used as ligands for transition metal coordination compounds. This is partially because of the instability of these complexes that undergo decomposition, disproportionation and oxidation ...

Redox and Spectroscopic Properties of Iron Porphyrin Nitroxyl in the Presence of Weak Acids [PDF]

, 2017
The spectroelectrochemistry and voltammetry of Fe(OEP) (NO) in the presence of substituted phenols was studied. Cyclic voltammetry showed that two closely spaced waves were observed for the reduction of Fe(OEP) (NO) in the presence of substituted phenols.
