Nitroxides, also known as nitroxyl radicals, are long-lived or stable radicals with the general
structure R1R2N–O•. The spin distribution over the nitroxide N and O atoms contributes to …

Persistent radicals can hold their unpaired electrons even under conditions where they
accumulate, leading to the unique characteristics of radical ensembles with open-shell …

Macromolecular protein assemblies are of fundamental importance for many processes
inside the cell, as they perform complex functions and constitute central hubs where …

Aliphatic amines are common constituents in micropollutants and dissolved organic matter
and present in elevated concentrations in wastewater-impacted source waters. Due to high …

An entirely metal-free catalyst system consisting of an easily prepared recyclable new
TEMPO derived sulfonic salt catalyst, and mineral acids (NaNO2 and HCl) has been …

Nitroxides are stable, kinetically-persistent free radicals which have been successfully used
in the study and intervention of oxidative stress, a critical issue pertaining to cellular health …
