Clean biogas - universally measurable

03-Dec-2025 - Researchers at the Paul Scherrer Institute PSI have developed a new analysis method that detects even the smallest amounts of critical impurities in biogas. Even small biogas plants can use the method without major investment - this promotes the energy transition. The market for biogas is ...

How machine learning can help predict the spectral properties of materials

07-Jan-2025 - Many techniques in computational materials science require scientists to identify the right set of parameters that capture the physics of the specific material they are studying. Calculating these parameters from scratch is sometimes possible but costs a lot of time and computational power. ...

Light amplification accelerates chemical reactions in aerosols

Temporal sequence of photochemical reaction in individual aerosol particles observed with high resolution

21-Apr-2022 - Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid ...

From photosynthesis to new compounds for eye diseases

03-Jan-2017 - Researchers supported by the Swiss National Science Foundation have succeeded in using X-rays to minutely observe a photosynthesis reaction and produce a movie of the event. The findings will aid understanding of similar processes in the human eye. Thanks to the new SwissFEL particle accelerator ...

Advanced imaging for bone research and materials science

High-resolution method for computed nano-tomography developed

30-Sep-2010 - A novel nano-tomography method developed by a team of researchers from the Technische Universität München (TUM), the Paul Scherrer Institute (PSI) and the ETH Zurich opens the door to computed tomography examinations of minute structures at nanometer resolutions. The new method makes possible, ...

How small is the proton?

International team of researchers observes unexpectedly small proton radius in a precision laser experiment with exotic hydrogen atoms

12-Jul-2010 - The proton - one of the universal building-blocks of all matter - is even smaller than had previously been assumed. This is the result obtained at the Paul-Scherrer-Institut (PSI) in Villigen (Switzerland) by an international research team, including scientists from the Max Planck Institute of ...

EMBL scientists develop first fully automated pipeline for multiprotein complex production

06-May-2009 - Most cellular processes are carried out by molecular machines that consist of many interacting proteins. These protein complexes lie at the heart of life science research, but they are notoriously hard to study. Their abundance is often too low to extract them directly from cells and generating ...

Molecules in the spotlight

New technique allows real-time observation of molecules during chemical reactions

16-Dec-2008 - A novel x-ray technique allowing the observation of molecular motion on a time scale never reached before has been developed by a team of researchers from Ecole Polytechnique Fédérale de Lausanne (EPFL) and the Paul Scherrer Institute (PSI) in Switzerland. Results of the research led by Professor ...
