On Thursday 22 September 2022, the annual NanoDay of the Laboratory of Nano and Quantum Engineering took place in Hannover. The latest research results from the interdisciplinary working groups in the field of nanotechnology were presented in eight lectures and a poster session.

This year there were 64 posters! The poster prizes sponsored by the Leibniz Universitätsgesellschaft e. V. went this year to:

• Tunable Distance of Nanoplatelets in Semiconductor Nanoplatelet/Polymer Hybrid Structures
  Rebecca T. Graf¹, Anja Schlosser¹, Dàniel Zàmbo¹, Jakob Schlenkrich¹, Pascal Rusch¹, Atasi Chatterjee², Herbert Pfnür², Nadja C. Bigall¹
