"Core-shell" cathodes for high performance Li-ion batteries
“Li-rich Ni-rich” core-shell particles are engineered as layered cathode materials for high energy Li-Ion batteries, including a controllable outer "Li-rich Mn-rich" shell improving cyclability.
Mechanism For All-Optical Magnetization Switching
X-rays reveal a non-collinear magnetic state as the base for all-optical magnetization switching.
Additive manufacturing of alloys with programmable microstructure and properties
Using laser powder bed fusion (LPBF) technology, we devise special processing strategies to ‘program’ the thermal stability of the as-printed alloy, such that it is possible to decide, a priori, how the material’s microstructure will evolve upon heat treatment
Biffo the fish: BiFeO3 nanoplate wins the Magnetism Art Competition at JEMS 2023 in Madrid
Dr. Tim A. Butcher from the Microspectroscopy group was awarded the first prize in the "Art in Magnetism" competition of the JEMS 2023 conference with his contribution "Biffo", obtained from a ptychography image of a BiFeO3 nanoplate.

A compact gas attenuator for the SwissFEL ATHOS beamline realized using additive manufacturing
Gas attenuators are important devices providing accurate variation of photon intensity for soft X-ray beamlines. In the SwissFEL ATHOS beamline front-end the space is very limited and an innovative approach has been taken to provide attenuation of three orders of magnitude up to an energy of 1200 eV. Additive manufacturing of a differential pumping system vacuum manifold allowed a triple pumping stage to be realized in a space of less than half a meter. Measurements have shown that the response of the device is as expected from theoretical calculations.
