Upcoming Conference: 25th ICXOM

The 25th ICXOM - International Conference on X-ray Optics and Microanalysis will be held from 5 - 9 August 2019 at The Westin Lombard Yorktown Center, Lombard IL, USA

25th International Congress on X-ray Optics and Microanalysis

The 25th International Conference on X-ray Optics and Microanalysis (ICXOM) was held at the Westin Lombard, IL, USA from August 5th to August 8th 2019.

New X-ray Laboratory Spectrometer

A new 100 W laboratory XAFS spectrometer was successfully commissioned in the Fittschen lab. On May the second the easyXES100-extended was installed in the Material-analysis group at the IAAC. It is one of seven (e.g. MPI-CEC, PSI, HIU Ulm) now installed all over the world. It allows to study elemental species in materials with poor crystallinity in the laboratory; which was previously an exclusive Synchrotron capacity. First of our measurements revealed species information on Vanadium oxidation state in Vanadium Redoxflow Batteries electrolyte. We will extend our studies to determine V species in the solid state components of the battery i.e. the ion exchange membrane and the electrodes.
