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.

Operando X-ray spectrotomography allows scientists to look inside of functioning chemical reactors. A research team at Karlsruhe Institute of Technology (KIT), at Paul Scherrer Institute PSI and at the European Synchrotron Radiation Facility (ESRF) in France have employed this method successfully.
Ultra-fast operando X-ray diffraction experiments reveal the temporal evolution of low and high temperature phases and the formation of residual stresses during laser 3D printing of a Ti-6Al-4V alloy. The profound influence of the length of the laser-scanning vector on the evolving microstructure is revealed and elucidated.
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.
