The new director of the Paul Scherrer Institute has taken up office today. Christian Rüegg aims to further reinforce the leading role of PSI's large research facilities, and thus promote Switzerland as a location for research.
Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. With its help, they disproved an established doctrine: that molecules in aerosols undergo no further chemical transformations because they are enclosed in other particulate matter.
At the ultracold neutron source at PSI, researchers have measured a property of the neutron more precisely than ever before: its electric dipole moment. That's because the search is still on for an explanation of why, after the Big Bang, there was more matter than antimatter.
Using a newly developed imaging method, researchers were able to visualise the magnetic structure inside a material with nanoscale resolution. They succeeded in creating a short "film" consisting of seven movie frames that shows, for the first time in 3D, how tiny vortices of the magnetisation deep within a material change over time.
On 27 November 2019, at the recommendation of the ETH Board, the Federal Council has appointed Christian Rüegg as the new director of the Paul Scherrer Institute PSI. The 43-year-old will take over from Thierry Strässle, who has headed the institute on an interim basis since the beginning of the year. Mr Rüegg is currently head of the Neutrons and Muons Division at the PSI. He will take up his new position on 1 April 2020.
Researchers at the Paul Scherrer Institute PSI have developed a new process with which fibre-reinforced composite materials can be precisely X-rayed. This could help to develop better materials with novel properties.
It is reminiscent of a paper bird made with the help of the Japanese folding art origami: a microrobot that uses the force of magnetic fields to move. In the future, such small machines could be used, for example, in medical operations.
Three researchers share this year's Nobel Prize in Chemistry. They are being honoured for their respective contributions to the development of lithium-ion batteries. Petr Novák of PSI likewise works in this area of research and has known the three laureates personally for decades. In an interview, he tells about sitting directly across from one of them at the crucial moment.
Researchers at the Paul Scherrer Institute PSI, together with colleagues from the pharmaceutical company F. Hoffmann-La Roche AG, have taken an important step towards the development of an active substance against the metastasis of certain cancers. Using the Swiss Light Source SLS, they deciphered the structure of a receptor that plays a crucial role in the migration of cancer cells.
For the first time, PSI researchers have used neutrons to visualise very strong magnetic fields that are up to one million times stronger than Earth's magnetic field. This now makes it possible to study magnets that are already installed in devices such as magnetic resonance tomography systems or alternators.
