At the biennial international meeting on MIcroscopy of Building Materials (EMABM- Euroseminar on Microscopy Applied to Building Materials), Mr. Arend and Dr. Wetzel presented results of the current DFG project "In-situ Microscopy for Additive-Particle Interactions". For the first time, the Euroseminar organized by Prof. Karl Peterson took place outside Europe. In Toronto, Kassel was selected as the venue for the 2023 meeting. We are already looking forward to hosting the meeting in four years and welcoming scientists from Europe and beyond to Kassel.
