The method of determining the hydroxyl number in polyols and oxo alcohols specified in DIN EN ISO 4629-2 derives its theory from the catalytic acetylation of the hydroxyl group. Once the intermediate ...
Polymeric polyols are prevalent in the production of polyurethanes and other specialized polymers. The hydroxyl number (OH#) measures the concentration of hydroxyl groups within the polyol. The ...
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 ...
Hydroxyl radical footprinting has been widely used for studying the structure of DNA and DNA–protein complexes. The high reactivity and lack of base specificity of the hydroxyl radical makes it an ...

Study uncovers role of hydroxyl radical in greenhouse gas production during soil drying–rewetting
In a new study published in Global Change Biology, Prof. Zhang Yuanming's team from the Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences has unveiled a previously ...
A new analysis of maps of the near and far sides of the moon shows that there are multiple sources of water and hydroxyl in the sunlit rocks and soils, including water-rich rocks excavated by meteor ...
