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.

Full-field X-ray absorption tomography reveals the chemical structure of defects in metal-organic frameworks
Cryo-full-field XANES computed tomography was used to visualize the presence and distribution of a second coordination polymer of reduced copper coordination within defect-engineered HKUST-1 MOF crystals. Observations encourage a revisitation of the structure-property relationships of defect-engineered MOFs.
How catalysts age
Catalysts used in industry change their material structure over the years. Using a new method, PSI researchers have now studied this on the nanoscale.
Look Inside a Chemical Reactor
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.
