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
Whitlockite in mammary microcalcifications is not associated with breast cancer
Microcalcifications, small deposits of calcium-containing minerals that form in breast tissue, are often, but not always, a warning sign of breast cancer. The relationship between microcalcifications and cancer has not been fully understood thus far. Researchers discovered now that the relationship between microcalcifications and tumors seems to be linked to the presence of a particular mineral called whitlockite, which is rich in magnesium and is found in microcalcifications only in the absence of tumors.
Unveiling the reaction mechanism shines light on the selectivity increase in catalytic processes
Increasing the selectivity of a chemical process through rational catalyst design is the Holy Grail of heterogeneous catalysis. Researchers at PSI and ETH Zürich showcase how revealing hidden steps in reaction pathways can steer processes towards preferred products, as demonstrated in a study focused on biomass valorization.
Tender X-rays show how one of nature’s strongest bonds breaks
Short flashes of an unusual kind of X-ray light at SwissFEL and SLS bring scientists closer to developing better catalysts to transform the greenhouse gas methane into a less harmful chemical.

3,1 millions de subventions pour de nouveaux projets de recherche au PSI
Zurab Guguchia et Kirsten Schnorr, tous deux chercheurs au PSI, reçoivent du Fonds national suisse des subsides de recherche d’un montant total de 3,1 millions de francs pour leurs projets tournés vers l’avenir.
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.
