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.Fluorescent nanodiamonds (fNDs) have emerged as an invaluable quantum sensing platform for biological and biochemical systems. This paper investigates the influence of common surface functionalization strategies for bioconjugation on the quantum properties of nitrogen vacancy (NV) centers in nanodiamonds.

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.

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals
Advanced Functional Materials, EarlyView.A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Sustainable landfill leachate treatment using refuse and pine bark as a carbon source for biodenitrification [PDF]
, 2014 Raw and 10-week composted commercial garden refuse (CGR) materials and pine bark (PB) mulch were evaluated for their potential use as alternative and sustainable sources of carbon for landfill leachate bio-denitrification.
