With its globally unique research infrastructure, PSI offers unrivalled opportunities for cutting-edge national and international research.
The main areas of research at PSI
Recent highlights from our research
Muons receive funding from the Swiss National Science Foundation
PSI gets an NCCR: The Muoniverse project will further expand research on the beamlines for elementary particles called muons – at the world’s leading facility for muon beams.
Identifying the sources of Sarajevo’s smog
Fumes from wood and coal burning as well as from cooking are the main sources of the heavy smog in the capital of Bosnia and Herzegovina. That’s the finding of a comprehensive mobile measurement campaign by PSI researchers.
A comprehensive energy system model for Switzerland
Energy systems face complicated, long-term challenges with a high degree of uncertainty. To explore these challenges and support decision-making, the STEM energy systems model from the Energy Economics Group at PSI has become a key tool.

Driving forces of mineral recrystallization in aqueous solutions derived from...
Curti et al., 2026
Recrystallization in aqueous solutions is a ubiquitous process susceptible to control the entrapment and release of toxic contaminants in the subsurface. However, unraveling the underlying mechanisms and driving forces has proven to be elusive, as recrystallization frequently follows different kinetic pathways even for the same mineral, depending on its initial state and pre-treatment. To obtain a better insight, a large body of experimental data from isotope tracer experiments carried out....
Swelling of Na-montmorillonite in the presence....
Owusu et al., 2026
Various dissolved gases, such as CO, H, and CH, may be present in the near-field geological repository due to metal corrosion or the degradation of organic waste. However, the influence of dissolved gases on the swelling behavior of bentonites, commonly used as backfill material, is still poorly understood. In this study, classical molecular dynamics simulations are conducted to....
Examining the pH dependence of Fe behavior in.....
Ban et al., 2026
Hydrotalcite-group layered double hydroxide (LDH) phases are important in many technical and geological contexts, and in applications ranging from environmental processes to catalysts to cements. This study systematically investigates the roles of Fe in LDH structures across varying....
