Scientists and Users The direct access for scientists, researchers and the users of our large facilities

Nickelate superconductors are intrinsically magnetic

Waves of magnetic excitation sweep through this new material whether in superconducting mode or not – another clue to the mystery of loss-less electric currents.

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.

Athos just got even better

An ambitious upgrade at the soft X-ray beamline of the free electron laser SwissFEL opens up new experimental capabilities.

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.
