Since the retirement of Prof. Dr.-Ing. Thomas Sattelmayer at the end of September 2021, the Chair of Thermodynamics has been temporarily headed by Prof. Wolfgang Polifke. With Prof. Dongsheng Wen taking up his post in mid-May, the transitional period has come to an end. The photos were taken during a "meet and greet" meeting for informal exchange with the new head of the chair. We wish Prof. Dongsheng Wen much success in leading the Chair of Thermodynamics into a bright future!
