Our forth colloquium is taking place online during our annual general meeting 2025 featuring an insightful talk by Prof. Dr. Matthias Arenz of University of Bern, Switzerland - a valued collaboration partner of several PIs. Dr. Arenz presented research on the Electrochemical Synthesis of High Entropy Nanoparticles and Their Applications in Electrocatalysis. Prof. Arenz showed how application-focused basic research in electrocatalytic energy conversion can more directly translate into devices for the future, highlighting the impact of innovative synthesis methods of High Entropy Nanoparctiles. The talk sparked engaging discussions, reinforcing the importance of electrochemical research.
