Heterogeneous Catalysis and Plasma Catalysis
On 8.11.2023, Leon Leffers (Univ. Twente) provided a crash course on heterogeneous catalysis and the prospect and principles of plasma catalysis. ECRs and PIs from the various disciplines of the CRC attended this crash course and discussed the details of connecting plasma phenomena to catalytic surface processes.
MGK Colloquium 2023 in Ulm
From 1.3. to 3.3. the MGK Colloquium meeting took place in Ulm. Besides the scientific exchange about transient atmospheric pressure plasma, an electrochemistry workshop was held at the University of Ulm. In addition, experts from other fields were invited.
Thanks to Angela Bayler from centrotherm international AG, Luca Vialetto from Christian-Albrechts-Universität zu Kiel, and Peter Hartmann from Wigner Research Centre for Physics in Budapest.
Virtual MGK colloqium 2022
With the start of the second funding period, all PhD students of the projects within the CRC 1316 were invited to participate in the annually MGK colloquium. The colloquium was held online at 7th and 8th of March 2022 and was organized by Maximilian Klich (project A8) and David Schulenberg (project A4).
The colloquium served as an introduction of the many new PhDs joining the CRC 1316 in its second funding period. Without the participation of project leaders it achieved a casual atmosphere for sharing scientific knowledge and interests between the PhD students. Here, they could introduce themselves and their projects as well as give a short summary about their projects achievements and future plans through talks or a poster presentation. Leading the talks regarding the different research topics modelling, DBD/RF discharges and plasma in liquids were the invited speakers which generated a well rounded experience.
The new funding period also required a few elections, namely the position of the PhD speaker formerly held by Maximilian Klich, as well as a position in the CRC 1316 gender board held by Lars Schücke (project A7) and Katharina Grosse (project B7). The newly elected PhD speaker is David Schulenberg and Stefanie Bogenrieder (project B4) as well as Lukas Forschner (project B12) are the new gender board representative.

Virtual MGK Colloquium
The scientific exchange among the CRC members and the group of Early Career Researcher occurred continuously during the three yearly project meetings and in the workshops organized by the CRC 1316 since it starting in 01/2018. However, it is very important that the ECR have also a platform to interact in a conference setting without the impact of their adviser to stimulate the discussions among the ECR. Instead, the CRC 1316 decided to organize an MGK Colloquium on its own by inviting the ECR from the CRC 1316 and from the SFB-TR 87. This meeting was organized by the ECRs J. Kuhfeld and P. Preissing in a virtual format on 21/04/2021. Prominent invited speakers at this event were Prof. A. Bogaerts (university Antwerp), Dr. S. Iseni (GREMI, Orléans) and Dr. T.L. Chng (LPP Paris). Beside presentations within a zoom meeting, virtual poster sessions were performed, enhancing the interaction between the ECR.
JSPS Core-to-core program
Patrick Hermanns visit research group in Osaka
I have visited Hamaguchi Laboratories at Osaka University in Japan for 3 months. The lab exchange was funded partially by the CRC-1316 and the JSPS Core-to-core program. The group of Prof. Satoshi Hamaguchi developed a reaction-diffusion-convection simulation for the generation and transport of chemical species in water, introduced by atmospheric-pressure plasma.
During my stay I worked on a multiphase fluid model. The typical flow field of a turbulent atmospheric-pressure plasma jet in direct vicinity of a liquid was modelled by solving a k-epsilon turbulence model. A Volume-of-Fluid (VOF) method was applied for the coupled flow of gaseous and liquid phase. The simulations agree very well with experimental results in the literature. The results from the fluid flow simulations were integrated into the reaction-diffusion-convection equations to evaluate the influence of different flow regimes on the generation and transport of chemical species in the liquid.
In Bochum University, I am working as a PhD-Student within project “B5: 2D-plasma-liquid-solid interfaces – plasma electrolytic oxidation“. The results generated can be useful for this project in regards of chemical species generation inside of liquids. In addition, the fluid flow model is interesting for other groups working with atmospheric-pressure plasmas (e.g. B2: “Self-organization of sub-µm surface structures stimulated by microplasma generated reactive species and short-pulsed laser irradiation“). Summarizing I can say, that I had a very pleasant stay in Osaka, that I personally enjoyed a lot. The cooperation with Hamaguchi Laboratories were very fruitful and everyone was very kind during my stay.
