This release is available in German. Ions—charged atoms or molecules—play an important role in nature, in our bodies as well as for science and technology. It is often necessary to trap, remove, mask, ...

A large issue with de-icers is that they temporarily protect the ground during the winter, but then also due to the nature of their chemical solution, cause problems for the ground throughout the rest ...

Many bacteria and unicellular algae have light-driven pumps in their cell membranes: proteins that change shape when exposed to photons such that they can transport charged atoms in or out of the cell ...
