Dr. Patrick Larpent and Dr. Masashi Nakahama visited the group of Rob Ameloot in KU Leuven in Belgium to carry out the JSPS-FWO collaboration research project. Patrick and Hammer enjoyed the work in a clean room and the nice discussion with the group members of Rob, in particular with the former MC2 visiting students Ivo and Sofie, over nice Belgian cuisine (plus of course beers)!! Thanks Rob for welcoming them.
