First coffee machine with integrated laser interferometer - April, April ;-)

Scientists at the Institute of Process Measurement and Sensor Technology and the NanoFab Research Training Group have demonstrated the integration of a laser interferometer into a coffee machine for the first time.

This means that the filling of coffee cups can now be dosed much more precisely than before. The interferometer can also be used to determine the spectrum of the coffee during filling by means of Fourier spectroscopy. This enables a highly accurate qualitative and quantitative analysis of the caffeine. Further research work is now to follow, using machine learning methods to evaluate the spectroscopic data in such a way as to intervene directly in the dosing process and directly influence the quality of the brewed coffee and tailor it to the taste of the coffee drinker.

New management of the GRK NanoFab

On 24.03.21, Prof. Steffen Strehle was elected as the new director and Prof. Thomas Fröhlich as the deputy director of the DFG Research Training Group NanoFab. They succeed Prof. Eberhard Manske and Prof. René Theska, who have led the Research Training Group in a proven manner over the past years. The election took place as scheduled in a subproject leader meeting, of course via video conference. Prof. Strehle heads the microsystems technology subproject and Prof. Fröhlich heads the process measurement technology subproject. In this constellation, the Research Training Group is well positioned to master the scientific challenges of the next 5 years. During this time, 26 doctoral students are expected to successfully complete their doctorates in three years on the basis of funding from the German Research Foundation. Research will focus on the development of new AFM tip and laser based 2D and 3D nanofabrication techniques based on high precision nanopositioning and nanomessing machines. The official handover of office will take place on 01.04.21.

Virtual RTG on-site inspection

The application for the continuation of the RTG 2182 NanoFab was sent to the DFG at the end of September 2020. To decide, whether the duration of the RTG will be extended, the DFG will carry out a virtual on-site inspection on the 13.01.2021. The inspection will be carried out by 6 international appraisers and 3 representatives of the DFG. During the inspection, the appraisers will interview the project leaders as well as the PhDs of the first and second generation via a Webex conference. Based on these interviews and the application documents, the appraiser group will render their judgement and decide about the RTG extension in summer/fall 2021. We are looking forward to the appraisal and hope for a positive verdict.

Continuation application for the second funding phase

The RTG's first funding period ends on schedule on 30.09.21. In order to be able to continue the scientific work in a third generation of doctoral students, the 13 sub-project leaders, together with the administration of the RTG, have prepared a continuation proposal (more than 300 pages in total) in the recent weeks. There, the updated research priorities, solution approaches and the general research environment are presented. The proposal was sent to the DFG in time, and all those involved are hoping for a positive decision after the review process at the beginning of next year.
