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 ...

Neutron radiography analysis of water management in a passive proton-exchange membrane fuel cell with superhydrophobic catalyst layers

Water transport in proton-exchange membrane fuel cells (PEMFCs) with superhydrophobic catalyst layers (CLs) has been studied with neutron radiography. Superhydrophobic CLs were deposited by electrospray on the membrane to be tested on the cathode and anode sides of the cells. The cells are operated under ...

300

The CNM center hosts 300 members of staff, in addition 40 PhD students perform their thesis work within CNM

5+1

The center is organized in 5 laboratories and 1 staff group.

3/30

CNM operates 3 of the 5 large scale user facilities: the Swiss spallation neutron source SINQ, the Swiss Muon Source SμS and the facilities for particle physics CHIRSP with approximately 30 experimental stations open for users.

1700

The facilities in the CNM center are open to international access — with approximately 1700 annual user visits the associated user program is a key activity for the center and for PSI as a whole.
