Aerosol formation in clouds: Studying climate modeling"s last great uncertainty factor
Researchers at the Paul Scherrer Institute PSI have studied for the first time how chemical reactions in clouds can influence the global climate. They found that isoprene, the dominant non-methane organic compound emitted into the atmosphere, can str.....»»
Twitter is exploring the use of Facebook-style emoji reactions
If you’re old enough to remember the outrage that followed Twitter’s decision to replace stars with hearts (aka likes instead of favorites), then you know that Twitter’s user base has strong feelings about how it wants to engage wit.....»»
New class of substances for redox reactions
Redox reactions play an important role in our everyday life. In these reactions, one compound releases electrons and is oxidized, while another accepts electrons and is reduced. Such redox reactions are exploited by living organisms, for example, to.....»»
Researchers gain insight into how solvent molecules impact light-driven reactions
Light-absorbing molecules can transform photons into electricity or fuels by shuttling electrons from one atom to another. In many cases the molecules are surrounded by a solvent—water, in the case of photosynthesis—and studies have shown that th.....»»
