The group of Prof. Björn Corzilius invited Selina Eckel for a talk in their physical chemistry seminar at the University of Rostock last week. She presented her recent results on the development of a broadband on-chip transmission-based EPR spectrometer. The group gave Selina an interesting lab tour which included their benchtop EPR spectrometer and 400 MHz/263 GHz DNP system, and they discussed possible collaborations.
