Cooperation
Continuous exchange between Bochum and GREMI laboratory
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.

Plasmas for renewable energies
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.
Internationalization
GEC in Japan was a success for CRC 1316 students
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".

New concept introduced in the plasma workshop of the project week
The project week for students at Ruhr University Bochum in grade 8 and 9 is a educational offer of the CRC 1316, Faculty of Physics and Astronomy from RUB and is greatly supported by zdi . From 4th to 7th October, the project week took place with four workshops hosting over 60 high school students.
The concept of the plasma workshop “From plasma to gold coating” was adapted accordingly to feedback by students and workshop leaders from the last years. The focus of the topics was shifted from theoretical work towards application based discussions with exercises to practice and apply newly gained knowledge. The focus has been set to enable the students to plan and execute their research as well as analyse the data and present their findings creatively and self-determined. The workshop leaders and material should guide through the workshop, offering the students a democratic say in the concrete design of the week.
To adapt the material to modern standards and the vast digital resources available for student online, the project guide now includes online resources that can be used for better understanding or diving deeper into different topics by using the QR-codes to access articles and videos. In the future, this guide can also be used with and on tablets and as a digital version, enhancing the interactivity and individualisation of the learning process of the students even further.
