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 ...

Researchers from the Innovation Academy for Precision Measurement Science and Technology (APM) of the Chinese Academy of ...

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.

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 ...

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 ...

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 ...

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, ...
