A warmer world is expected to bring more thunderstorms, especially at higher latitudes. Scientists are now reporting a ...

At the center of this removal process is the hydroxyl radical (OH)—a highly reactive molecule responsible for removing about 90% of methane in the lower atmosphere.

The reactive chemical species generated in an atmospheric-pressure plasma jet (APPJ), such as hydroxyl radical and atomic oxygen, are generally regarded as the major sources for several biomedical ...

The hydroxyl radicals were generated by UV-irradiation of hydrogen peroxide, and the radicals were detected by spin trapping electron spin resonance (ESR) with 5,5-dimethyl-1-pyrroline- N -oxide (DMPO ...

Radical yields were quantified by spin-trapping and electron paramagnetic resonance (EPR) spectroscopy. The EPR spectra of free radicals in the nicotine salt aerosol matched those generated from the ...

Cysteine disulfides, which constitute an important component in biological redox buffer systems, are highly reactive toward the hydroxyl radical (•OH). The mechanistic details of this reaction, how ...
