In-situ neutron tomography study of a dehydrating and hydrating packed bed for thermochemical heat storage
To study the heat and water vapor transport and reaction kinetics in a packed bed of thermo-chemical material on both reactor and tablet level, an in-situ neutron imaging study of a dehydrating and subsequently hydrating packed bed consisting of cylindrical K2 CO3 tablets was performed at the Paul Scherrer Institute ...
Field-Induced Magnon Decay, Magnon Shadows, and Rotonlike Excitations in the Honeycomb Antiferromagnet YbBr3
The search for new quantum many-body phenomena in magnetic materials has a strong focus on highly frustrated systems and the resulting quantum spin-liquid state. However, even unfrustrated magnetic materials show a multitude of unconventional features in their spin excitation spectra. By using the synergy of ...
Generating structured foam via flowing through a wire array
Efficient manufacturing methods could unlock foams with tailored, anisotropic properties. Conventional foam production methods rely on the self-arrangement of bubbles, typically leading to isotropic materials, or involve intricate additive layering processes. This study presents a simple, passive technique to modify the foam structure. A set of thin parallel wires ...
PSI electronics apprentices once again perform very successfully at the SwissSkills Championships 2025
At the biennial SwissSkills Championships for young professionals, which took place in Bern from 17 to 21 September 2025, four of our former and current electronics apprentices demonstrated their exceptionally strong skills with great success in two different competition categories.
