His time at TUHH was dedicated to fruitful discussions with researchers across the CRC, focusing on how thermodynamic perspectives can contribute to understanding complex processes and interpreting experimental results in the SMART Reactor development. The visit provided an excellent opportunity to explore collaborative paths and identify interfaces where molecular thermodynamics can bridge theory and application. We truly value Prof. Chapman’s ongoing role as a Mercator Fellow and look forward to continued exchange and joint work in the future.
