microXAS - X05LA: Environmental & Materials Sciences
Two additional features make the microXAS beamline a rather exceptional and exclusive X-ray microprobe facility. First, the microXAS beamline permits the investigation of radioactive materials and corresponds to the world-wide solely microprobe facility being able to analyze radioactive sample with 1µm spatial resolution. Second and definitely going beyond any existing X-ray microprobe instrumentation, the FEMTO project is an integral part of the microXAS beamline project. Ultrafast time-resolved X-ray studies with a resolution of picoseconds down to ~100 femtoseconds are ‘routinely’ carried out at the microXAS beam line.

Lithium ion batteries (LIB) are essential in modern everyday life, with increasing interest in enhancing their performance and lifetime. Secondary particles of Li-rich cathode material were examined with correlated ptychographic X-ray tomography and diffraction microscopy at different stages of cycling to probe the aging mechanism.
Moving Atoms by Photodoping
Understanding how and how fast we can drive atoms to create a structural phase transition is of fundamental interest as it directly relates to many processes in nature. Here we show that a photoexcitation can drive a purely structural phase transition before the energy is relaxed in the material that corresponds to a “warmer” equilibrated state.
