In his opening remarks, CZM Board Spokesperson Prof. Wolfgang Maus-Friedrichs emphasized the importance of academic exchange: “I am delighted that so many representatives from various disciplines have come together.” More than 60 researchers presented the latest developments in the field of materials science research.
Dr. Sebastian Levin, from the Institute of Materials Science and Engineering (Clausthal University of Technology), delivered a keynote lecture on the degradation—that is, the breakdown of the body and cellular structures—of cold-water coral skeletons. The result of changing conditions in the world’s oceans is a deterioration in mechanical and technological properties, which, due to structural instability, poses a threat to coral habitats. Since a healthy coral skeleton possesses the strength of concrete, there is great potential to use such materials as sustainable construction materials and to produce them via bioprinting.
On the second day of the symposium, Dr. Hagen Poddig of H.C. Starck Tungsten delivered a keynote presentation on a new process in the recycling chain for the production of tungsten chemicals. Essentially, this involves concentration during the production of ammonium metatungstate, the key starting material for the production of pure tungsten or tungsten carbide. Unlike standard thermal concentration, the newly developed reverse osmosis process saves 90 percent of the energy originally required.
Physicist known from an ARD program gives an evening lecture
In his evening lecture titled “A Ray of Hope Instead of a Blackout,” physicist Vince Ebert—known from the ARD program “Wissen vor Acht”—delivered a humorous appeal. He called for an open-minded approach to solving the current challenges of climate change and the energy transition. At the evening reception that followed, the symposium’s topics were reviewed and discussed over food and drinks provided by the research brewery.
Three presentations by doctoral candidates were recognized for their outstanding rhetorical and substantive qualities: Alexander Koch (TU Dortmund) on the topic “Bonding mechanisms of directly recycled aluminum chips for new semi-finished products,” Sebastian Kaiser (Federal Institute for Materials Research and Testing) on “Welding in the operation of hydrogen transmission pipelines,” and Sascha Zimmermann (TU Clausthal) on the “Design of manufacturing environments for oxygen-free production.”
Conference Proceedings on Increasing Visibility
Many of the papers will be published in English, following peer review, in the printed conference proceedings and digitally as open-access publications. The goal is to increase the visibility of all the papers in particular and of the symposium in general. “We would like to extend our sincere thanks to all the participating reviewers. The feedback shows that we are on the right track,” summarized CZM Managing Director Dr. Henning Wiche.
