Making sense of the muon’s misdemeanours
An exotic atom called muonium could explain why muons won’t stick to the rules, believe researchers using the Swiss Muon Source at Paul Scherrer Institute PSI.
Upgraded pixel detector back in action at CERN
Built at Paul Scherrer Institute, the detector forms the heart of the CMS experiment. It is producing data again following an upgrade during the LHC shutdown.
Dancing molecules
When cycloalkanes are enclosed in a nanometer-sized pore, they adapt their shape - similar to the induced fit concept described in #biochemistry. The molecules do not all behave in the same way and surprisingly start to move when there is a lack of space at 5K.
Perspective on muon-spin rotation/relaxation under hydrostatic pressure LMU
Pressure, together with temperature, electric, and magnetic fields, alters the system and allows for the investigation of the fundamental prop- erties of matter. Under applied pressure, the interatomic distances shrink, which modifies the interactions between atoms and may lead to the appearance of new (sometimes exotic) physical properties, such as pressure-induced phase transitions; quantum critical points; new structural, magnetic, and/or superconducting states; and changes of the temperature evolution and symmetry of the order parameters...

How computer simulations are helping ensuring a safe and efficient transfer of used nuclear fuel from temporary dry storage to its final resting place deep underground.
Automated synapse-level reconstruction of neural circuits in the larval zebrafish brain
Researchers from the Max Planck Institute for Biological Intelligence, Google Inc. and the Paul Scherrer Institute published a new method and data resource that makes connectomic analyses of the entire larval zebrafish brain possible.
How mixing of atmospheric aerosols affects the environment
Peering inside atmospheric particles provides clues to effects on climate and health, finds Paul Scherrer Institute and University of British Columbia study.
On-track for SLS2.0: First magnet series measured
Successful measurement of the first 112 magnets puts the PSI magnet section on-schedule to measure all of the 1000+ magnets needed for SLS2.0 by July 2024.
Li-ion solvation in TFSI and FSI - based ionic liquid electrolytes probed by X-ray photoelectron spectroscopy
We demonstrate the capability of conventional laboratory XPS to determine the anions solvation shell of Li+ cation within 1M of LiTFSI and 1M of LiFSI salts dissolved in (EMIM+-FSI-) and (EMIM+-TFSI-) ionic liquids. The binding energy difference between the N1s components originating from the EMIM+ cation and from TFSI- or FSI- anions, solvating the Li+, confirms that both TFSI- and FSI- contribute simultaneously to the Li+ solvation. Additionally, the degradation of the TFSI and FSI -based electrolytes under X-ray exposure is proved.
