We are very happy that we had the chance to be part of the inauguration of the United Nations University Hub at the Technische Universität Hamburg. It was a great honor to show Tshilidzi Marwala, the Rector of the United Nations (UN) University and UN Under-Secretary-General, and his delegation our showcase of a prismatic spouted bed and to explain how fluidized bed technology can support the university's mission "Engineering to face climate change". We are very much looking forward to continuing our work in this important research field.
