Atomic path from insulator to metal messier than thought

Researchers have peeked behind the curtain of the ultrafast phase transition of vanadium dioxide and found its atomic theatrics are much more complicated than they thought. It's a material that has fascinated scientists for ...

SwissFEL makes protein structures visible

For the development of new medicinal agents, accurate knowledge of biological processes in the body is a prerequisite. Here proteins play a crucial role. At the Paul Scherrer Institute PSI, the X-ray free-electron laser SwissFEL ...

Extremely small and fast: Laser ignites hot plasma

When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. For fractions of a second, a plasma is created. The electrons ...

First published results from new X-ray laser

With the publication of the first experimental measurements performed at the facility, the European X-ray Free-Electron Laser (EuXFEL) has passed another critical milestone since its launch in September 2017. It is the first ...
