BMBF NanoMatFutur Networking Event, Berlin 14.02.-15.02.2024

In recent years, it has not been possible to organise a network meeting for the group leaders of the BMBF NanoMatFutur and BattFutur junior research groups due to the coronavirus pandemic. This year the time had finally come and we were able to present our projects to each other, exchange ideas and network and get to know the PtJ and VDI staff in person. The event took place at the Federal Ministry of Education and Research (BMBF) not far from the Chancellery in Berlin.
