Laboratory for Synchrotron Radiation and Femtochemistry
Mission
We develop and apply x-ray-based tools to solve scientific and technological questions in chemical research and related fields. Our world-leading instruments allow us to extract electronic and structural information from complex systems and to follow chemical processes from the initial electronic excitation to reaction mechanisms under operando conditions. We collaborate with Swiss and international scientists to advance academic and industrial research.
Scientific Highlights
PSI researcher Patrick Hemberger honored in the Rising Stars special issue in Energy & Fuels
To celebrate contributions of highly influential early and mid-career researchers in energy research, the journal Energy & Fuels established an annual recognition of Energy and Fuels Rising Stars.
Finding Ketenes in the Methanol to Olefins Process
How are the first olefins formed in the early stages of the methanol-to-olefins process? Detection of two reactive ketene species solves this long-standing puzzle.
The chemical complex that regulates body zinc storage
Zinc deficiency compromises the immune system and is a global public health problem. Through experiments at the Swiss Light Source SLS and BESSYII, researchers gained new insights into zinc storage, with implications for understanding COVID-19 severity.
Reaction insights help make sustainable liquid fuels
Methanol made from CO2 in the air can be transformed into carbon neutral fuels. New mechanistic understanding aids development of this sustainable alternative.
New SwissFEL soft X-ray endstation welcomes first users
Maloja is go. First user experiments mark a double first, not only for the Maloja endstation but also for the second beamline of SwissFEL, Athos.
Hercules School 2022
PSI hosted again the Hercules School in March 2022. We had the pleasure to welcome 20 international PhD students, PostDocs and scientists to demonstrate our state-of-the-art techniques and methodologies at our large scale facilities, the Swiss Light Source (SLS), the Swiss Spallation Neutron Source (SINQ) and our free electron laser SwissFEL.
Simulation soll bei Aufräumarbeiten in Fukushima helfen
Eine neue Simulation der gefährlichsten radioaktiven Trümmer des Kernkraftwerks Fukushima soll bei Aufräumarbeiten helfen.
Watch them growing: New mechanistic insights into catalytic methane coupling
Methane valorization is a promising technology to utilize this platform compound to produce aromatics and hydrocarbons. Researchers from PSI and ETH Zürich unveiled this reaction mechanism and observed the molecular growth from the ground up. Besides stepwise CH3 addition, novel routes involving the dimerization of resonantly stabilized propargyl (C3H3) radicals to benzene (C6H6) were identified. These mechanistic insights will aid the development of valorisation strategies.
Geheimnis der Stradivari-Geigen enthüllt
Wie ein internationales Team von Forschenden herausfand, griffen die alten italienischen Meister Stradivari und Guarneri beim Geigenbau zu unerwarteten chemischen Hilfsmitteln.
