Scientific Highlights
European map of aerosol pollution can help improve human health
Researchers have measured and determined the sources of aerosol pollution at 22 locations in Europe.
Power-to-gas system for energy independence
New technology provides synthetic natural gas for domestic heating
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.
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.
Rescuing Earth’s icy memory
An international research team with PSI participation is rushing to preserve glacier ice for posterity.
Scientists map Arctic aerosols to better understand regional warming
In order to better understand climate change in the Arctic and design effective mitigation measures, scientists at EPFL and PSI have studied the aerosols in a region spanning from Russia to Canada.
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.
Asthma: diagnosis in a single breath
PSI is involved in the development of a breath test that can be used to diagnose asthma. Imad El Haddad explains why such a test could be extremely useful – especially for children.
