CIN­SaT Au­tumn Col­loquium 2019

This year’s CINSaT Autumn Colloquium continues to thrill and attracts many professors, academic staff and students to the lecture hall.


On Wednesday, 16th of October 2019, the annual autumn colloquium of the CINSaT took place in lecture hall 282 at the Heinrich-Plett-Straße of the University of Kassel. Numerous professors, doctoral students, as well as undergraduate and graduate students from various disciplines waited excitedly for the lectures of the guest speakers. The autumn colloquium, which is open to all who are interested, offers not only the opportunity to listen to interesting topics on current nanotechnology research, but also to inform themselves about the current research contents of the CINSaT during the poster session.

The colloquium started with a warm welcome speech of Prof. Dr. Johann Peter Reithmaier, head of the CINSaT, who led into the first part of the lecture series that was opened by Prof. Dr. Peter Felfer from the University of Erlangen. In his lecture " Atomic Scale Analysis of Material using Atom Probe Tomography" he explained how to obtain a 3D reconstruction of the composition of a specimen with atomic resolution. Following this, Prof. Dr. Piet O. Schmidt from the PTB Braunschweig captivated the audience with his exciting lecture "Optical Clocks" in which he addressed the usage of unconventional optical clocks for the test of fundamental physics and quantum logic spectroscopy of Ar13+ ions.

After a half-hour coffee break, which was used not only to get to know each other, but also for the first review of the posters, the second part of the lecture series followed. Dr. Claudia Geisler from the Laser-Laboratorium Göttingen e.V. presented her lecture entitled "Optical Nanoscopy: Imaging beyond the Diffraction Limit" in which she talked about STED microscopy, for instance.

The last talk of the session, entitled “True optical sectioning for 3D microscopy: Three-dimensional specimens in light sheet-based fluorescence microscopy (LSFM)”, was given by Prof. Dr. Ernst H.K. Stelzer from the Universität Frankfurt. In his application-oriented talk he demonstrated not only a short history of different microscopy types he developed, but also about multi-dimensional data collection.

The poster session following the lectures achieved a new record with 64 posters. The foyer in front of lecture hall 282 offered not only enough space for the numerous poster contributions, but also for extensive scientific discussions and the exchange of information on current research content within the CINSaT. The catering of the Studentenwerk of the University of Kassel provided again for the well-being during the event. The interdisciplinary cooperation within the CINSaT has been pronounced through cross-working-group poster contributions or related posters of the LOEWE SMolBits Project.

The conclusion of the event was the presentation of the poster prizes awarded by this year's jury - consisting of CINSaT members Prof. Dr. Thomas Giesen, Prof. Dr. Monika Stengel, Prof. Dr. Ulrich Siemeling and apl. Prof. Dr. Thomas Fuhrmann-Lieker - for the three best poster contributions was awarded (1st prize tablet, 2nd prize retro gaming console, 3rd prize external SSD). The jury emphasized the high scientific quality of the posters.

This year, the first price was given to the poster "Optical and morphological characterization of lanthanide complexes" by Miriam Gerstel from the Nano Optics Group (PD Dr. Mohamed Benyoucef). The second and third prize were given to Tanja Finke (Nano Materials Group, Prof. Dr. J.P. Reithmaier) with her poster entitled "GaAs based quantum dot structures for VECSEL and MIXSEL applications" and Pablo Rojas (Theory of Ultrafast Phenomena, Prof. Dr. M. Garcia) for his presentation about “Diffusion-based minimal oscillators in transcriptional networks”, respectively. Due to the high number of participants, both in the audience as well as the poster contributions, and the thematically balanced lectures of the guest speakers, the CINSaT Autumn Colloquium was again a complete success.
