The main areas of research at PSI
Recent highlights from our research
Important funding for muon research
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.

Low-frequency electrochemical pulsing to manage flooding and salt precipitation in zero-gap CO2-to-ethylene electrolyzers
The electrochemical conversion of CO2 to ethylene offers a promising approach to expand manufacturing of commodity chemicals and fuels. Specifically, ethylene is a critical precursor for polyethylene a $240B industry. Expanding productivity ...
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....
