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 ...

How to find anti-cancer agents

"By combining the three fragments into one molecule, we hoped to enhance the effect, since the new molecule fills the binding pocket better"

14-Apr-2022

Researchers at the Paul Scherrer Institute PSI and the Italian Institute of Technology IIT have developed a novel substance that disables a protein in the cell skeleton, leading to cell death. In this way, substances of this type can prevent, for example, the growth of tumours. To accomplish ...

A look into the magnetic future

Researchers at PSI and ETH Zurich have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes

06-Apr-2022

This view into processes that take place within so-​called artificial spin ice could play an important role in the development of novel high-​performance computers. When water freezes to form ice, the water molecules, with their hydrogen and oxygen atoms, arrange themselves in a complex ...

Novel X-ray lens facilitates glimpse into the nanoworld

Together with spin-off XRnanotech, PSI plans to market the new lens

16-Mar-2022

PSI scientists have developed a ground-breaking achromatic lens for X-rays. This allows the X-ray beams to be accurately focused on a single point even if they have different wavelengths. The new lens will make it much easier to study nanostructures using X-rays, according to a paper just ...

New rapid test could detect coronavirus and flu simultaneously

It could also detect other diseases and different coronavirus variants

26-Jan-2022

Researchers from the University of Basel and the Paul Scherrer Institute PSI have developed a rapid test for Covid-19 with a novel functional principle. Although it requires further testing and improvements, the initial results are promising: As well as determining whether a Covid-19 infection is ...

Uniquely sharp X-ray view

For the first time, it is possible to look inside materials with a resolution down to individual atoms

26-Apr-2021

Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The experiment at PSI is a milestone in observing processes in the world of atoms. The structures on ...

Molecular energy machine as a movie star

09-Jul-2019

Researchers at the Paul Scherrer Institute PSI have used the Swiss Light Source SLS to record a molecular energy machine in action and thus to reveal how energy production at cell membranes works. For this purpose they developed a new investigative method that could make the analysis of cellular ...

Bringing information into the cell

30-Apr-2019

Researchers at the Paul Scherrer Institute PSI have elucidated an important part of a siganalling pathway that transmits information through the cell membrane into the interior of a cell. This siganalling pathway is of great significance for all mammals, since it is involved in various important ...

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 ...
