More sustainable recycling of plastics

Plastics are among the most widely used materials, and they are vital components of all modern technologies. So far, it has been possible to recycle these valuable materials only to a limited extent. In order to offer novel ...

Extreme UV laser shows generation of atmospheric pollutant

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and photochemical smog. The technique, ...

How aerosols are formed

ETH Zurich researchers conducted an experiment to investigate the initial steps in the formation of aerosols. Their findings are now aiding efforts to better understand and model that process—for example, the formation ...

Switching DNA functions on and off with light

DNA is the basis of life on earth. The function of DNA is to store all the genetic information an organism needs to develop, function and reproduce. It is essentially a biological instruction manual found in every cell. Biochemists ...
