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 ...
"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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
09-Jun-2016
Researchers at the Paul Scherrer Institute's Swiss Light Source in Villigen, Switzerland, have developed a new design for X-ray spectrometers that eschews a commonly utilized component to lowers overall production costs and increase the efficiency of x-ray flux, which may lead to faster ...
