We are proud to announce our 2ndonline-workshop on data quality assessment at the 26th of November at 9:00am CEST on Zoom.

We are proud to announce our cooperation with Dr. rer.nat. habil. Horst Borrmann from the Max-Planck Institute for Chemical Physics of Solids, Dresden, on systematic errors in diffraction experiments. The focus is on exposing, describing and removing certain types of frequently occuring errors and on methodological improvements.

We are proud to announce our online-workshop on data quality assessment at the 9th of October at 9:00am CEST on Zoom.

We are proud that we have been part of the IUCr 2021 in Prague. We have organized a workshop on data quality assessment at the 14th of August 2021 in Prague. The workshop was held in a hybrid version, which means there were some real participants and some virtual.
Thank you, it was an awesome experience!

We are proud to announce that we are supported through the EXIST Program by the Federal Ministry for Economic Affairs and Energy together with the European Social Fund for Germany. Our special Thanks goes to the PtJ Jülich.

First official statement from University of Bayreuth. Thank you for being or cooperation partner. Specially we want to thank Prof. Dr. Rodrigo Isidor our Mentor! Another big “Thank you” goes to Christian Teringl and Petra Hammon for helping us with all our needs and concerns.
