"Hoist the sails, full speed ahead" was the motto again this year, when 41 PhD students from the Chair of Chemical Process Engineering (AVT.CVT) and DWI Leibniz-Institut für interaktive Materialien left the safe ground and set sails. The event known as the "Rursee Seminar" took place this year under the new name "SEAminar" on the IJsselmeer. On board of course, the enthusiastic sailor and scientific director Professor Möller. In a unique setting, the participants of the two institutes were able to exchange ideas intensively and interdisciplinary. Whether in discussions about the progress of their research after the scientific talk of each participant, preparing lunch in teams or in teamwork during sailing, communication was key to success.
