Ternary Synergy in Layered Double Hydroxides for Efficient and Stable Nitrate Reduction
Advanced Functional Materials, EarlyView.Ternary CuZnFe LDH enables efficient electrocatalytic nitrate‐to‐ammonia conversion via controlled in situ reconstruction: zinc leaching creates porous active sites, copper reduced to metallic copper, while iron oxide keeps stable. Synergistic Cu‐Fe redox coupling drives tandem catalysis (nitrate→nitrite→NH3), achieving 95% Faraday efficiency and ...

Ratio of natural isotopes of nitrogen. I. Primary results: soils of Dombes [Translation from: Revue d'Ecologie et de Biologie du Sol 14, 279-287, 1977] [PDF]
, 1980 Utilization of the heavy isotope of nitrogen as a tracer has found numerous applications in soil biology. It allows better definition of different stages of the nitrogen cycle, in particular the immobilization-mineralization cycle.

An investigation into the unusual linkage isomerization and nitrite reduction activity of a novel tris(2-pyridyl) copper complex [PDF]
, 2017 The copper-containing nitrite reductases (CuNIRs) are a class of enzymes that mediate the reduction of nitrite to nitric oxide in biological systems. Metal–ligand complexes that reproduce the salient features of the active site of CuNIRs are therefore of

Advanced Functional Materials, EarlyView.This paper synthesizes CuO@CuCo2O4 catalysts via an emulsion hydrothermal method. Among them, CuCuCo2O4 perfectly inherits the advantages of CuO and Co3O4 and successfully connects the reactions in series. During the electrolysis process, CuO is reduced to Cu.

In Vitro and in Vivo Effects of Alkyl Nitrites on Methionine Synthase from Mouse Kidney and Liver
Pteridines, 1989 The effect of butyl and isoamyl nitrites on methionine synthase from mouse kidney and liver was investigated. A strong specific inhibition of the enzyme (50% at 7.3 x 10 4 M nitrites for kidney methionine synthase) was found.
