As an interdisciplinary field, fluorine chemistry touches on many aspects that are relevant to the daily lives of non-chemists as well. Almost everyone has used fluorinated medications at some point, such as flurbiprofen, which is found in throat lozenges. Modern fuel cells, on the other hand—which could play a role in future propulsion systems—cannot function without fluorinated membranes. In addition to these topics, which were primarily discussed at NatLab, fluorine chemistry also featured in Prof. Sebastian Hasenstab-Riedel’s very popular experimental lecture and, of course, in many other conversations between SFB researchers and interested participants at the Long Night.
