Plasma Physics for high school students
The project week for high school students is an educational program of the CRC 1316, the Faculty of Physics and Astronomy at the RUB and of zdi (Zukunft durch Innovation; Future through innovation). Which takes place twice a year.
From April 3-6 , the project week was hosted for 60 female students in grades 8 to 10. The girls chose be- between four workshops: plasma physics, astronomy, physics in medicine and sustainable house design. The project “From Plasma to Gold Layers” allows the students to gain an insight into the generation and applications of plasmas. Using the sputter coater and professional laboratory equipment, the students could deposit and examine gold layers themselves. During the project week, the students attended a lecture by Prof. Dr Judith Golda on “hands-on plas- mas – between material science and medicine“, and visited laboratories and the Planetarium Bochum. On the closing day, the results of the students’ research were presented in a poster session, followed by a quiz and lunch. The next project week in Autumn for female and male students in grades 8 and 9 will take place from October 9-13 .
The Faculty of Physics enables students to complete a school internship in Physics. From March 27-31, we welcomed two interns from grade 9. After a short introduction to plasma physics, the students worked on the sputter coater. They examined the coated samples. For this purpose, they determined the transmission with a spectrometer, the layer thickness with the profilometer and the conductivity. The interns also gained experience in handling data and in data evaluation. The goal of the internship is also to give an impression of laboratory work and current research. Therefore, doctoral students, bachelor’s and master’s students guided the interns through the labs and presented their experiments. The interns also visited the NRW state competition “Jugend forscht”, which took place at the Ruhr University Bochum March 27-29 .
The “mobile plasma workshop” took place for the first time on June 5, and visited an 11th-grade physics class in Essen. In the beginning, the students watched a short movie and received basic knowledge about plasmas and their applications. After a short quiz, they worked on the experiments in smaller groups. The students examined the light emitted by plasmas with an optical spectrometer and observed how electric and magnetic fields can influence plasmas. Information on the experiments on the students' tablets guided the workshop. The workshop was a success, and the students showed great interest. Through the students’ feedback, we have gained insights on how to improve our workshop going forward. 
DAAD Exchange
Scientific results of DAAD exchange presented at ISPC 25
Prof. Judith Golda from RUB and Prof. Claire Douat from GREMI in Orléans have arranged several exchange visits between the groups with measurement cam- paigns in the respective laboratories within the frame- work of a DAAD exchange program (part of a PROCOPE project) and have already partially carried them out. The focus of the exchange is on the investigation of the role of CO in the treatment of biological substrates.
At the end of April, the French delegation consisting of Prof. Claire Douat, Eloise Mestre and Dr. Inna Orel was again in Bochum to measure rotational temperatures on the kHz-jet from Orléans. Here, with the support of Dr. Laura Chauvet as well as Daniel Henze in the labora- tory of Prof. Judith Golda, experimental results could again be obtained. In the end, several successful meas- urement campaigns were carried out over the last few visits. Therefore, the revisit was used to lay the foundation for a cooperative publication of the two groups, which will be submitted soon. Finally, Eloïse Mestre presented their results at the ISPC 25 conference in Kyoto, Japan.

ISPC25 with the best oral presentation prize winner from RUB
The biennial international symposium on plasma chemistry was held in Kyoto, Japan at the end of May. A large delegation of Bochum plasma physicists and plas engineers attended the conference.
The conference covered most aspects of plasma from different fields: plasma medicine, plasma-based gas conversion, plasma in liquid, plasma process and material engineering, plasma spectroscopy and diagnostics, etc. The symposium provided a great opportunity to make new contacts and maintain relationships. The poster session was also very informative and provided a great opportunity to learn about the latest developments in plasma chemistry.
Overall, the 25th Symposium on Plasma Chemistry in Kyoto was a great success.
Congratulations to Simon Kreuznacht (EP2, RUB) for winning an award at the ISPC25 in Kyoto for his oral presentation on “Space resolved temperature measurements in an argon methane microwave plasma used for hydrogen production”. The Oral Presentation Awards are assigned to the best oral presentations provided by students.
Heraeus Seminar "Non thermal plasmas for sustainable chemistry"
The CRC 1316 was involved in the organization of the 785 WE Heraeus Seminar "Non thermal plasmas for sustainable chemistry" that was held in Bad Honnef 22.4.-27.4.2023. The meeting was organized by Yiguang Yu (Princeton), Tomo Nozaki (Tokyo Tech), Annemie Bogaerts (U Antwerp), and A. von Keudell (RUB, SFB 1316). The SFB 1316 contributed with two invited presentations and 6 posters. The seminar with 80 attendees provided a broad overview on the field and critical discusssions about the challenges and potential of plasma methods for sustainable chemistry.
