Free radicals, molecules with an unpaired valence electron, such as the hydroxyl radical, play a crucial role in the industrially important conversion of natural gas, primarily methane, to ...

Methane, CH 4, is readily broken down in the atmosphere, where sunshine and highly reactive hydroxyl radicals are abundant. But it’s a different story when chemists try to work with the molecule.

This reaction lowers the amount of hydroxyl radicals near a person’s skin. Once it steals that hydrogen atom from ethanol, the radical becomes a stable molecule of water.

The removal of trace gases from the troposphere is, in most cases, initialized by reactions with hydroxyl radicals. An evaluation of this process (sometimes termed self-cleansing) using existing ...

Methane lasts for maybe a decade in Earth's atmosphere before it begins to react with a free radical called hydroxyl and turns into carbon dioxide, where it can stay there for centuries.

The hydroxyl radical (OH) is generated in complex chemical cycles and removes organic gases by reacting with them. This includes the potent greenhouse gas methane—OH removes about 90% of it from ...

The most important cleaning agents in the atmosphere are hydroxyl (OH) radicals, which oxidise volatile organic compounds such as methane and isoprene. The reaction with the short-lived but highly ...

Antarctica may seem pristine and almost devoid of life, but there's plenty of chemistry going on. Victoria Atkinson explains ...

The study explains that hydroxyl radical is the main atmospheric sink for methane and even minor changes in its concentration can result in the rate that methane emissions accumulate in the ...
