Cherned up to the maximum
In topological materials, electrons can display behaviour that is fundamentally different from that in ‘conventional’ matter, and the magnitude of many such ‘exotic’ phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached — and controlled — in a real material.
Analytical Research Infrastructures as key resources for the five Horizon Europe Missions
Moon-shot missions, such as those of Horizon Europe, require exceptional solutions, and the world-leading Analytical Research Infrastructures of Europe (ARIEs) are one of the key places those solutions can be sought. The ARIE Joint Position Paper highlighting how the common, complementary approach will help address the societal challenges of the Horizon Europe Missions framework programme was presented today.
To the sun and beyond
PSI takes part in space research projects. This not only expands knowledge about our astronomical home, but also reinforces Switzerland's reputation as a reliable developer of sophisticated space equipment.
Grosser Rat bewilligt 2,4 Millionen für Technologiezentrum Anaxam
Der Kanton Aargau unterstützt das Technologietransferzentrum Anaxam in Villigen für die Dauer von vier Jahren mit insgesamt 2,4 Millionen Franken. Der Grosse Rat hat am Dienstag in Spreitenbach den entsprechenden Kredit mit 124 zu 3 Stimmen bewilligt.
Elucidating the mechanism of a light-driven sodium pump
Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in recording a light-driven sodium pump from bacterial cells in action. The findings promise progress in developing new methods in neurobiology. The researchers used the new X-ray free-electron laser SwissFEL for their investigations.
First MX results of the priority COVID-19 call
The Dikic group at the Goethe University in Frankfurt am Main, Germany has published the first results following the opening of the "PRIORITY COVID-19 Call” at SLS.
Operando X-ray diffraction during laser 3D printing
Ultra-fast operando X-ray diffraction experiments reveal the temporal evolution of low and high temperature phases and the formation of residual stresses during laser 3D printing of a Ti-6Al-4V alloy. The profound influence of the length of the laser-scanning vector on the evolving microstructure is revealed and elucidated.
Long-lived pionic helium: Exotic matter experimentally verified for the first time
Exotic atoms, in which electrons are replaced by other particles, allow deep insights into the quantum world. After eight years, an international group of scientists have succeeded in a challenging experiment conducted at PSI’s pion source: they created an artificial atom called “pionic helium”.
In search of the lighting material of the future
At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). This new understanding at the atomic level will help to develop new lighting materials that have higher light output and also are cost-efficient to manufacture.
