Guest at Experimental Physics II

Sylvain Iséni stays two weeks for electric field measurements on micro cavity plasma arrays

Dr. Sylvain Iséni stayed from October 21st until October 31st, 2019, in the group of Prof. Achim von Keudell. His visit is part of the collaboration with his home institute, GREMI, espacially, Prof. Remi Dussart. Particularly, the focus of the recent visit is are eletric field measurements by optical emission spectroscopy in the project A6 (Dr. Volker Schulz-von der Gathen, Sebastian Dzikowski) of the CRC1316. In the project micro cavity arrays are investigated.
Furthermore, Dr. Iséni used the chance to participate in the online seminar and had a talk with the title "Temperate micro-plasmas for environmental purposes: sources, properties, cross-diagnostics & challenges".

Guests

Emile Carbone visits the research group experimental physics V

On Oktober 25th, 2019, Dr. Emile Carbone from the Max-Planck institute for plasma physics in Garching, Germany, is going to visit the research group of Prof. Czarnetzki. Dr. Carbone is research group leader of the group Plasma for Gas Conversion and is invited to the Ruhr-Universität Bochum in the framework of the CRC 1316. Moreover, he is going to have a seminar talk at experimental physics V about "CO2 dissociation by microwave plasmas: prospects and challenges" at 10:15 in NB 5/158. Everyone who is interested is welcome to join!

Cosmology explained in a television program

Prof. Hildebrandt was guest in a television program and explained cosmology. Moreover, he pointed out the importance of basic research. The full episode of the television program "Planet Wissen" can be found here.

Plathinium conference in Antibes

Several projects from the Coordinated Research Centers CRC 1316 and SFB-TR 87 presented their research at the 1st Plathinium Conference (September 16th until September 20th) in Antibes. This conference is a newly combined meeting of the former French vacuum congress, the French assembly on magnetron sputtering and thin films as well as the French conference on ion beam techniques. The PhD students Sascha Monje-Thiemann, Julian Held and Dennis Engels presented their work on low pressure magnetized plasmas in the poster session. Christian Hoppe gave an oral contribution on defects in SiOx coatings. Achim von Keudell presented a plenary lecture on atmospheric pressure plasma chemistry and contributed with a tutorial on fundamentals of plasmas to a workshop preceding the meeting. Achim von Keudell was also elected to become the chair of the 2nd Plathinium conference in 2021.

ALD conference in Seattle

The 19th Conference on Atomic Layer Deposition took place from 21st until 24th July in Seattle. Two groups from the RD Plasma joined the conference namely Prof. Devi from inorganic materials chemistry as well as researchers from theoretical electrical engineering. With six oral and numerous poster presentations, the conference was a great success for the members of the RD Plasma.

Guests

Prof. Satoshi Hamaguchi visits RUB

Next week, from September 9th on, Prof. Hamaguchi from Osaka university is going to visit the RUB. He is Merator fellow of the SFB 1316 and stays for three weeks until September 27th.

Moreover, Prof. Hamaguchi and his JSPS Core-to-Core program, the exchange between Japanese and German scientists, was approved. This means that following his visit here, more students will go to Osaka university in the near future as well as the RUB will welcome Japanese students within the exchange program.

Guests EP2

Erasmus student joins CRC 1316 project

Between March 25th and July 19th, 2019 the Erasmus student Roel Michiels visits the research group EP2 of Prof. von Keudell at Ruhr University Bochum. He joins project A3 from the CRC 1316 "Excitation transfer between molecules in transient atmospheric pressure plasmas and its impact on plasma chemistry".

Roel Michiels is associated with the group of Annemie Bogaerts from the Department of Chemistry at the University of Antwerp. He finished his Bachelor thesis last year and prepares now for his Master degree. The topic of his Master thesis is micro kinteic modelling of plasma catalysis. The modelling is done via Density functional theory (DFT) and Molecular Dynamics (MD).

Together with Theresa Urbanietz, Christoph Stewig, and Steffen Schüttler he tries to gain experience in experimental work in Bochum. His work here focuses on the measurement as well as on the analysis of FTIR spectra gained in the project.

First (V)UV-double-monochromator calibration measurements at AG Benedikt in Kiel

To achieve a relative intensity calibration of a (V)UV-monochromator, the use of the double monochromator method is common. Two monochromators work in tandem, and the difference in the spectrum from a stable light source of the first monochromator through the second monochromator is utilized to obtain a relative intensity calibration. From July 8th until July 12th, Beatrix Biskup, from project B2 of the SFB-TR 87, stayed at the university in Kiel to achieve the monochromator calibration.
The monochromator from Bochum was transported beforehand to the AG Benedikt at CAU (Christian-Albrechts-University) in Kiel. The technical staff made all the preparations necessary for the monochromators from Bochum and Kiel to work together in tandem. Together with Dr. Judith Golda and Prof. Dr. Jan Benedikt in Kiel, Beatrix Biskup did the first test measurements, which could be accomplished. Further cooperation with the research group will be executed in future.

Plasma barbeque 2019

On Wednesday July 3rd, the annual Plasma barbeque took place at Ruhr-Universität Bochum. Students from the physics faculty as well as from the electrical engineering could meet PhD students from both faculties and inform themselves about plasma studies in a pleasant atmosphere.

ISPC 24 in Naples

Between June 11th and 14th, the 24th International Symposium on Plasma Chemistry took place in Naples, Italy. A group of seven peole from the CRC 1316 as well as from the SFB-TR 87 joined the meeting. An honour was given to Achim von Keudell, who had a plenary talk on High power impulse magnetron sputtering – extreme plasmas for extreme materials. Also, Julia Bandow from project B8 of the CRC1316 had an invited talk on Plasma meets biotechnology – coupling plasma and enzymatic reactions. Further, Marc Böke had a talk on Separated effects of plasma species and post- treatment on the properties of barrier layers on polymers and Patrick Preissing presented his work on NO production in the COST Reference Microplasma Jet and a dielectric barrier discharge measured by means of Laser Induced Fluorescence (LIF).

10th International Workshop on Microplasmas in Kyoto

This year, the 10th edition of the International Workshop on Microplasmas took place in Kyoto. The scope of the workshop are the generation/sources of microplasmas, modelling, and applications (material processing, biomedical material treatments, environmental devices etc.). Around 70 participants from all over the world joined the meeting. A group of nine people from Bochum, especially from the CRC 1316 joined the conference. Finally, two oral presentations and six poster presentations were given by them.

An oral presentation was held by Sebastian Dzikowski from project A6 from the CRC 1316 with the title "Initial ignition behavior of a micro cavity plasma array (MCPA)". Moreover, an invited talk was given by Dr. Volker Schulz-von der Gathen from the CRC with the title "Micro cavity plasma array devices: From first ignition to continuous operation".
