According to a study published in Water Research in April 2020, superoxide produces hydroxyl radicals in lake water. Hydroxyl radicals break down poorly biodegradable organic matter such as humic ...

How the radical scavenger TEMPO traps a hydroxyl radical OH·. The proton of the hydroxyl radical reacts with TEMPO first. Colour coding: grey for C (carbon), white for H (hydrogen), red for O (oxygen) ...

Scott F. Singleton, an associate professor of medicinal chemistry and natural products at the University of North Carolina School of Pharmacy, calls the results "wonderfully unexpected, but in a way ...

The hydroxyl radical (•OH) is among the most reactive species in water, playing a pivotal role in atmospheric chemistry, environmental remediation and biological damage. Generated chiefly by ...

New mass spectrometry experiments challenge water microdroplet’s purported ability to spontaneously generate hydroxyl ...

A rapid atmospheric reaction critical to breaking down pollution in the lab has been observed by chemists. They identify an important intermediate molecule and track its transformation to hydroxyl ...

Scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical and hydroperoxyl ...

The reactive hydroxyl radical, which helps sop up pollutant molecules in Earth’s atmosphere, has now also been found in the hellish atmosphere of Venus. The discovery promises to help scientists ...

A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land increased atmospheric methane at an unprecedented rate in the early ...

Air quality is literally a matter of life and death. More than one in 10 deaths worldwide are attributed to dirty air, polluted through a matter of means and molecules, which makes the battle to clean ...

The human body's exposure to ozone in indoor spaces generates highly reactive hydroxyl (OH), radicals which are largely responsible for the oxidation of most pollutant gases, researchers report. The ...
