Deep learning to avoid weather disappointments
Saharan dust storms played havoc with weather predictions. Invertible neural networks to retrieve aerosol properties from light scattering data may help.
Light amplification accelerates chemical reactions in aerosols
Together with colleagues at ETH Zürich, Peter Alpert and Markus Ammann have directly imaged where light was amplified and where it was not inside photochemically active particles using X-ray spectromicroscopy.
Sauvegarder la mémoire de la glace
Une équipe internationale de recherche, à laquelle participe le PSI, se hâte de conserver des carottes de glace pour la postérité.
Réchauffement climatique: une cartographie des aérosols en Arctique
Pour mieux comprendre l’évolution du climat et développer des mesures efficaces contre la pollution, des chercheurs de l’EPFL et du PSI ont étudié les aérosols présents de la Russie au Canada.
New Head of Laboratory for Energy Systems Analysis (LEA)
As of February 1st 2022, Russell McKenna joins the Paul Scherrer Institute’s Laboratory for Energy Systems Analysis (LEA) as head of the Laboratory. The position at PSI and the full professorship at ETHZ will enable him to combine his research with teaching activities. This optimally reinforces the cooperation between ETH Zurich and the two energy sectors, ENE and NES, of the PSI.
Optimization of catalyst performance to increase efficiency of methanol production
Many types of catalysts have been well known for decades, but the fundamental understanding as to why they work so well is still not quite clear. Without this understanding, an even more efficient catalyst cannot be developed, which is needed to reduce the global energy demand. Copper-zinc-alumina (CZA) is a popular catalyst and has been used for about 100 years, as it facilitates the production of the important chemical building block methanol, a molecule that enables the storage of hydrogen in a manner that minimizes negative impact on the carbon-dioxide footprint. Until 2021, scientists debated over the reason why the catalyst works so well. Understanding the reason behind this is vital in order to further develop even better ones. The copper-zinc-alumina (CZA) catalyst is assessed at the Laboratory for catalysis and sustainable chemistry (LSK) of the Paul Scherrer Institute.

Andrea Baccarini, a former PhD student at the Laboratory of Atmospheric Chemistry, has been awarded the ETH Medal for his thesis investigating aerosol formation in the Arctic and Antarctic and the role aerosols play in climate change.
Diagnostiquer l’asthme dans un souffle
Le PSI participe au développement d’un test respiratoire, grâce auquel il devrait être possible de diagnostiquer l’asthme. Une interview avec Imad El Haddad.
E-fuels and electrification as complementary approaches to achieve climate target
Sustainable, synthetic fuels, so-called e-fuels, can help reduce CO₂ emissions. For their production, electricity from renewable sources is required in order to allow for a close to CO₂-neutral balance. The availability of electricity from renewable sources, which ensures the climate benefits of e-fuels, is currently still limited. “Especially in order to produce on a larger scale, a lot of renewable electricity is needed,” explains Christian Bauer, researcher at the Laboratory for Energy Systems Analysis (LEA) at PSI.
