  • Mechanism Deciphered: How Organic Acids Are Formed in the Atmosphere

    The acidity of the atmosphere is increasingly determined by carbon dioxide and organic acids such as formic acid. The second of these contribute to the formation of aerosol particles as a precursor of raindrops and therefore impact the growth of clouds and pH of rainwater. In previous atmospheric ch more

  • Particulates are more dangerous than previously thought

    Researchers at the Paul Scherrer Institute PSI have for the first time observed photochemical processes inside the smallest particles in the air. In doing so, they discovered that additional oxygen radicals that can be harmful to human health are formed in these aerosols under everyday conditions. I more

  • Flowers of St. John's Wort serve as green catalyst

    An interdisciplinary team of scientists from the School of Science at TU Dresden has for the first time used dried flowers of St. John's Wort (genus Hypericum) as an active catalyst in various photochemical reactions. This conceptually new and sustainable process was registered as a German patent an more
