In the research field “Geosciences”, 143 highly cited researchers were appointed worldwide this year, 7 of them from Switzerland, 2 of them from the Paul Scherrer Institute.
The Laboratory of Atmospheric Chemistry has initiated innovative data-science-based modelling approaches to discover the most important pollution sources for human health
PhD student Martin Heinrich of the Molecular Nanoscience group won the best poster award at the Nano-BW 2021 symposium at Bad Herrenalb (Germany), October 6-7. The symposium is held annually within the research network “Functional Nanostructures” of Baden-Württemberg.
Martin introduced his project in the form of a poster titled “Local Manipulation of Spin Domains in a Multiferroic Rashba Semiconductor”. His project started in July 2021 and is funded by the Swiss Nanoscience Institute (SNI) Basel. The poster award was selected by the vote of all attendees.
The CLOUD experiment at CERN will be recreating particle formation in key regions of the globe to understand the effects of these particles on regional climates
Fluoroethylene-carbonate is often referred to as a film-forming electrolyte additive for Li-ion batteries, resulting in high quality Solid–Electrolyte-Interphase on negative electrode, however, the underlying mechanism, even if thought to be known, has been only clarified due to our targeted experimental design, combining systematic electrochemical, chemical and microscopy characterization techniques. We have shown that first the formation of inorganic LiF-rich particles appear and only later the carbonate-rich film is actually formed.
Emergence of spin-orbit coupled ferromagnetic surface state derived from Zak phase in a nonmagnetic insulator FeSi
FeSi is a nonmagnetic narrow-gap insulator, exhibiting peculiar charge and spin dynamics beyond a simple band structure picture. Those unusual features have been attracting renewed attention from topological aspects. Although the surface conduction was demonstrated according to size-dependent resistivity in bulk crystals, its topological characteristics and consequent electromagnetic responses remain elusive. Here, we demonstrate ...
Unconventional Pressure Dependence of the Superfluid Density in the Nodeless Topological Superconductor α-PdBi2
We investigated the superconducting properties of the topological superconductor α-PdBi2 at ambient and external pressures up to 1.77 GPa using muon spin rotation experiments. The ambient pressure measurements evince a fully gapped s-wave superconducting state in the bulk of the specimen. Alternating current magnetic susceptibility and muon spin rotation measurements manifest a continuous suppression of Tc with increasing pressure.
In a study published in Science, ambient-pressure X-ray photoelectron spectroscopy reveals spontaneous redox chemistry at solvating particle surfaces.
PUBLISHED IN SCIENCE: A surface-promoted redox reaction occurs spontaneously on solvating inorganic aerosol surfaces
Ammonium sulfate has been used as a probe for aerosol particles and investigated in situ by means of ambient pressure X-ray photoelectron spectroscopy. Unexpectedly, when the particles start to absorb water, a spontaneous redox reaction leading to nitrogen and elemental sulfur takes place.
Hard X-ray cryo-tomography scanning of retina from healthy and inherited blindness specimen paves the way for correlative analysis after imaging at the cSAXS beamline.
