Thursday was opened by presentations from the Produktionstechnisches Zentrum Hannover (PZH), introducing the institute and the research work being carried out there. Afterwards, via video link, Prof. Frank Mücklich then promoted collaboration on the new edition of Prof. Petzow's etching book classic.

The focus of the meeting was on the evaluation of the joint trial launched last year on the reduction of hazardous substances in etching using electrolytic etching processes. Here, the possibilities are being explored to what extent classical etching processes with higher-concentration hazardous substances can be substituted by electrolytic etching processes with solutions based on low concentrations of hazardous substances. The results will be presented at this year's metallography conference in Saarbrücken.

The evening of the first day was concluded with a convivial meal together.

The next day was used for a tour of the institute. During a tour of the modernly equipped laboratories and pilot plants, the participants gained an intensive insight into the very good opportunities available to students and researchers at the Institute of Materials Science.

All in all, a very successful and welcome event for all participants after a long break!
