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.

Outreach

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".

Cooperation

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.
