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 ...

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, 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.

Methane is one of the most powerful greenhouse gases, significantly contributing to global warming. It also affects the ...

The hydroxyl radical is important in the atmosphere because it initiates chemical reactions and breaks down molecules like the greenhouse gas methane. OH is the main driver of many compositional ...

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 ...

Both of these compounds affect the concentration of hydroxyl radical, ... In 2020 the methane growth rate anomaly grew to 5.2 ppb/year compared with 2019, ...

A hydroxyl radical “is like a wild animal,” Williams says. “All it wants to do is rip the hydrogen off another molecule.” This reaction lowers the amount of hydroxyl radicals near a person ...
