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.


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 cooperation between project B7 and the Forschungszentrum Jülich  

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.

GEC conference 2022 in Japan

After two years of social distancing and online meetings, 2022 will be known as the year that gave rebirth to on-site conferences. Since the beginning of the year, many conferences have returned, and so has the GEC (gaseous electronics conference). From Monday (Oct 3rd) to Friday (Oct 7th), the international low-temperature plasma community met in Sendai, Japan. As the organizers would not get tired of emphasizing, they were hyped about finally realizing an in-person event again. The community shared this enthusiasm.

Almost six hundred papers were presented to five-hundred-fifty participants- the third most papers within the last ten years- and an attendance comparable to online events. Another notable statistic of the conference is the high count of students. Half of the participants were students, which included Ph.D. students as well as undergrads. With thirty-three contributions, a large group from Bochum and the SFBs attended GEC. Similar to the conference, this group had a dominant share of Ph.D. and undergrad students.

At least four parallel sessions were conducted to fit the numerous contributions into the five days available. Scientific highlights of the conference were the workshops conducted on Monday and the price talks; given on Wednesday. Professor Toshiaki Makabe received the "Will Allis Prize'' to acknowledge his life's work in plasma science, and Professor Masaru Hori received the "Reactive Plasma Award'' for his research. In terms of success, the SFBs, SFB-TR87 and CRC1316, did not fall too short in comparison. Andrew Gibson, Lars Schücke and Jan Trieschmann (former two CRC 1316, latter SFB-TR87) were invited to present their research. Julian Schulze (PI in both CRCs) chaired and organized the GEC, and five people from the consortia were chosen as session chairs.

Moreover, two outstanding performances have to be mentioned. The respective committees priced the oral presentation of Tobias Gergs and the poster presentation of Arisa Bodnar. Tobias Gergs is a member of the SFb-TR87 and got awarded the "Student's Excellence Award". Arisa Bodnar presented her Bachelor thesis, which she did in the frame of the CRC 1316, and received the "Student Poster Price". All in all, the large share of people and their valuable contributions caused the SFBs to impact the conference meaningfully.

The wholesome and successful experience is reflected in the happy faces in the picture above.


CRC 1316 members joining the International Plasma School

A large group of ten people from the SFB 1316 consortium participated in the 25th International School on Low-Temperature Plasma Physics. To deepen their knowledge of plasma science and technology, the PhD students from Bochum and Ulm attended the plasma school for one week. In addition to lectures, the school's program also included workshops and poster sessions.


Large CRC1316 participation in the International Plasma School

The 25th edition of the International Plasma School on Low-Temperature Plasmas took place from 1th to 5th October at the Physics Centre in Bad Honnef. Afterwards, the two-day Master Class on electric propulsion has been held. 76 participants from sixteen nations joined this yearly event. The international chair of the Plasma School was in the hands of Prof. Dr. Holger Kersten and Prof. Dr. Jan Benedikt from CAU Kiel.

The extensive program offered various topics to the students: from theory to applied plasma technologies. The lectures (23 from eight nations) were accompanied by a social program that allowed for intensive discussion with the teachers. Every evening there was a question and answer session with the teachers of the day, where an exciting exchange had been held. Hands-on workshops also provided practical experience in the field of spectroscopy.

Moreover, a large number of PhD students from the CRC 1316 and accompanying projects were part of the event this year.
