On Thursday 10th October 2019 the annual NanoDay of the Laboratory of Nano and Quantum Engineering took place in Hannover/Germany. In eight lectures and a poster session the latest research results from the interdisciplinary working groups in the field of nanotechnology were presented. This year there were 65 posters - record! The poster prizes sponsored by the Leibniz Universitätsgesellschaft e. V. were awarded this year:
