New class of substances for REDOX chemistry
The compounds known as ‘pyrazinacenes’ are simple, stable compounds that consist of a series of connected nitrogen-containing carbon rings. They are suitable for applications in electrochemistry or synthesis, as the researchers describe in the science journal Communications Chemistry. They were first designed, synthesized and chemically characterized in solution by the Hill team and carefully investigated by Scanning Tunneling Microscopy and Surface Chemical Analysis. The compounds have been shown to reversibly release and accept electrons and arrange themselves differently depending on the oxidation state. Interestingly, the oxidation and reduction reactions of the pyrazinacenes are not only affected by a chemical impulse, but can also be stimulated by light so they can be considered photo-redox active.
Safely stored for a million years
Switzerland plans to construct a deep repository for its radioactive waste. There are three potential locations, and data obtained by PSI researchers can aid in selection of the best one.
HERCULES SCHOOL 2021 AT PSI
During the week of March 15 – 19, we had the pleasure to welcome 20 international PhD students, PostDocs and assistant professors at PSI, taking part in the first virtual HERCULES SCHOOL on Neutrons & Synchrotron Radiation.
Insights into the world’s oldest pile carpet
High-resolution XRF imaging of the specific metal distribution within wool fibers at the PHOENIX beamline gives insights into traditional oriental dyeing procedures.
Forschung zu Covid-19 am Paul Scherrer Institut
Während viele Bereiche des Lebens eingeschränkt sind, bleiben wichtige Forschungsanlagen am PSI in Betrieb.
Watching receptor proteins changing shape
In our bodies, G protein-coupled receptors mediate countless processes. PSI researcher Ramon Guixà talks about how he brings those receptor molecules to life on the computer screen.
New blueprint for more stable quantum computers
PSI researchers have shown how faster and better defined quantum bits can be created. The central elements are magnetic atoms from the class of so-called rare-earth metals, selectively implanted into the crystal lattice of a material.
Clocking the movement of electrons inside an atom
Scientists pioneer an approach called self-referenced streaking, clocking Auger electrons with sub-femtosecond resolution. The breakthrough will unlock the broader potential for attosecond time resolution at X-ray free-electron lasers
PSI equips the Swiss Light Source SLS for the future
Green light for SLS 2.0: The planned upgrade of the Swiss Light Source SLS can proceed; the funding is provided for within the framework of the ERI Dispatch for 2021-2024, which has been approved.
