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.

Atmospheric globe-trotters

The CLOUD experiment reveals a new mechanism by which atmospheric particles form. The particles rapidly travel the world, globally impacting cloud formation and climate.

Spin keeps electrons in line in iron-based superconductor

Electronic nematicity, thought to be an ingredient in high temperature superconductivity, is primarily spin driven in FeSe finds a study in Nature Physics.

Things run smoother without lubricants

At the particle accelerators of PSI, the components have to withstand harsh conditions. This is why a special ball bearing that does not require grease as a lubricant has been in use since last year.

Welcome to the PSI Science Portal. On this site you find information on PSI's different research activities and on the experimental opportunities at PSI's large scale research infrastructures.
