From 1.3. to 3.3. the CRC 316 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.
We are happy to announce the second workshop on research data management in Plasma Science. NP, CAU and RUB are now organizing the 2nd Workshop on FAIR Data in Plasma Science, which will take place from May 3-4, 2023 at the Event Center at Ruhr-Universität Bochum, see also https://www.plasma-mds.org/ws-fair-data-plasma-science-2.html.
The workshop is aimed at researchers at different stages for exchange on the topic of data management. Topics of the workshop are electronic lab journals, practical questions in the daily handling of research data management systems as well as the presentation of already established solutions. In addition, an interactive part is planned, which will deal with the question of how to get standards into the laboratory. Here, all participants are invited to contribute their ideas and your practical expertise.
Prof. Dr. Martin Muhler was awarded the Alwin Mittasch Prize 2023 for his "fundamental contributions to the cross-scale understanding of the mode of action of catalyst materials in chemical reactions for future-oriented technologies". This award is given to researchers for outstanding achievements in the field of catalyst research by German Society for Catalysis. The award will be handed over in Weimar on March 16, 2023.
Prof. Dr. Martin Muhler holds the Chair of Technical Chemistry at Ruhr-Universität and is a board member of SFB 1316, PI in project A7 "Plasma catalysis for conversion of volatile organic compounds (VOC)", as well as a member of the MGK.
The lecture "Introduction to plasma physics II" and Bachelor, Master and PhD students of the chair EP2 and the group Plasma Interface Physics visited the company Plasmatreat in Steinhagen near Bielefeld. The company excels in the production of atmospheric pressure plasma jets for polymer functionalization.
On Saturday, 11.02.2023, the kick-off event of the Science Year 2023 "Our Universe" took place. The SFB 1316 was represented with a booth at the Zeiss Planetarium Bochum.
Besides live experiments, there was a varied program with a plasma quiz, coloring pictures and slide show. As live experiments, the plasma sphere and plasma mass were presented as hands-on experiments, and the plasma speaker and COST jet were shown for demonstration. Here, the new portable COST-Jet could be used for the first time outside the university. Thanks to its construction on a plate with gas supply, generator and holders for optical fibre and spectrometer, another experiment and authentic diagnostics from the laboratory can now be shown at events.
A big thank you to the many helping hands and all interested people who visited us!
Congratulations to Henrik van Impel, who won the student award of Ruhr University Bochum with his bachelor thesis "Diagnostics of atomic oxygen in a micro-cavity plasma reactor". He received his certificate during the yearly celebration of the University hosted by the Rector of the University.
In his bachelor thesis, Mr. van Impel used actinometry to investigate the formation of atomic oxygen in a plasma array reactor. With his finding, he made an important contribution to project A6 in CRC 1316.
The DAAD exchange program (part of a PROCOPE project) between Prof. Judith Golda from Ruhr University Bochum and Prof. Claire Douat from GREMI allowed several exchange visits between both groups.The exchange focuses on the study of the role of CO in the treatment of biological substrates.
Cold atmospheric pressure plasmas could provide a well-controlled local source of small-dose CO that can be directly guided to the treatment zone. The aim of the project is to investigate the production pathways and the role of the CO molecule during the plasma treatment of biological material. Possible synergism of CO and plasma produced species such as electric fields, ions and electrons, photons and other neutral radicals are analysed.
In detail, several exchange visits from both labs were realized. In July, Jun.-Prof. Judith Golda, Dr. Laura Chauvet and Daniel Henze from the CRC 1316 were guests in the laboratory of Prof. Claire Douat at the GREMI in Orléans. In a joint measurement campaign, two different atmospheric pressure plasma jets were being tested. They measured the production of CO at different operating conditions with a gas analyser.
In October, directly after the Plasma School in Bad Honneff, Eloise Mestre visited the PIP group. The second measurement campaign focused on the measurement of plasma produced CO in a kHz jet source using mass spectrometry.
Finally, Jun.-Prof. Judith Golda and Dr. Sebastian Burhenn stayed in the laboratory of Prof. Claire Douat at the GREMI in Orléans for a joint research campaign in November again. This time, the work was focused on the measurement of plasma-produced carbon monoxide affecting human hemoglobin.

Achim von Keudell gave a lecture on "Plamas for renewable energies" in the popular lecture series "Saturday morning physics" of the faculty for physics and astronomy on the 10th December 2022. He highlighted the various research topics of the CRC 1316.
Bachelor's student Arisa Bodnar from the Ruhr University won the Student Poster Award at this year's APS Gaseous Electronics Conference in Sendai, Japan, with her contribution "Improving the decomposition of polluted air streams using additional metal plates in a dielectric double-surface discharge system with multiple electrodes." In this poster contribution, Arisa investigates surface dielectric barrier discharges (sDBD) that are used to decompose volatile organic compounds (VOCs) from industrial exhaust gases (e.g., chemical plants).
Furthermore, PhD student Tobias Gergs from the Ruhr University Bochum won the GEC Student Award for Excellence at the GEC in Sendai, Japan, with his contribution "Dynamic surface surrogate model trained on atomistic data of AlN sputter depositions".

Pulsed plasmas in liquids are intensively investigated in project B7 of the CRC 1316. One possible application of these plasmas is the generation of nanoparticles directly in the liquid. These particles are deposited from the electrode material during the plasma ignition and thus particles of different sizes are generated. Now cooperation with the Forschungszentrum Jülich, a method is to be developed to to produce composite nanoparticles during plasma operation in liquids. For this purpose, the researchers Dr. Katharina Laake and Elia Jüngling from project B7 have travelled to Forschungszentrum Jülich to produce the first prototypes for electrode tips, which will which can later be used to produce composite nanoparticles.

The Physics and Astronomy Department's Faculty Celebration is held annually. Here the graduates of the last year are honored. The ceremony if organized by the different chairs of the department. This year, the chair of Experimental Physics II with the Plasma Interface Physics group had the privilege of hosting the event. The celebration was on October 21st 2022 in the large lecture hall of the Department of Physics. This is a good opportunity to introduce the research field and to present the current research topics.
The event was moderated by Maike Kai and Philipp Maaß. Prof. Dr. Achim von Keudell and Prof. Judith Golda presented their research and some plasma physics experiments.
As a highlight, Dr. Katharina Laake (born Grosse) from the B7 project of the CRC 1316 gave a very descriptive and target group-oriented lecture (as award lecture for receiving the dissertation prize of the Wilhelm and Else Heraeus Foundation) on the topic "Temporal Evolution of Nanosecond Pulsed Plasmas in Water". The award was presented to her during the event by the Dean of Studies of the Faculty, Prof. Dr. Heiko Krabbe.
Afterwards, the lecturers of the faculty were honored. Here, Prof. Dr. Judith Golda received the lecturer award of the student council. The award is given to the most popular lecturer of the last year among the students.
Finally, PD Dr. Tsanko Tsankov from project A2 of CRC 1316 received his habilitation certificate. He accepted his habilitation entitled "Kinetics of Non-Equilibrium Plasmas" at the faculty on November 21st. Congratulations to all!
