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
A star is born
Swiss Light Source SLS reveals complex chemistry inside ‘stellar nurseries’
3,1 Millionen Förderung für neue Forschungsprojekte am PSI
Die beiden PSI-Forschenden Zurab Guguchia und Kirsten Schnorr erhalten vom Schweizerischen Nationalfonds Förderbeiträge von insgesamt 3,1 Millionen CHF für zukunftsweisende Projekte.
Tracking chemical bond changes with element selectivity and in real time
X-ray photoelectron spectroscopy probes the chemical environment in a molecule at a specific atomic site. Now the concept is extended with a site selective trigger to follow chemical bond changes as they occur on the femtosecond time scale.
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.
