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 ...
