The scientific exchange among the CRC members and the group of Early Career Researcher occurred continuously during the three yearly project meetings and in the workshops organized by the CRC 1316 since it starting in 01/2018. However, it is very important that the ECR have also a platform to interact in a conference setting without the impact of their adviser to stimulate the discussions among the ECR. Instead, the CRC 1316 decided to organize an MGK Colloquium on its own by inviting the ECR from the CRC 1316 and from the SFB-TR 87. This meeting was organized by the ECRs J. Kuhfeld and P. Preissing in a virtual format on 21/04/2021. Prominent invited speakers at this event were Prof. A. Bogaerts (university Antwerp), Dr. S. Iseni (GREMI, Orléans) and Dr. T.L. Chng (LPP Paris). Beside presentations within a zoom meeting, virtual poster sessions were performed, enhancing the interaction between the ECR.
Honour of research of project A5
Project A5 on the Inside Front Cover of Plasma Processes and Polymers
The current issue (April 2021) of Plasma Processes and Polymers features work from project A5 of the CRC 1316 on the topic of "positive and negative streamer propagation in volume dielectric barrier discharges with planar and porous electrodes" on its inside front cover.
The scientists have found that the discharge characteristics of negative surface streamers differ significantly from those of positive surface streamers. While negative streamers develop along the dielectric surface, allowing them to propagate into much smaller dielectric pores, positive streamers floatingly develop above the dielectric.
The article on the research findings and the Inside Front Cover are freely accessible online.

One research center “Future energy materials and systems” will support the plasma science at RUB in the area of synthetic plasma chemistry. Plasma chemistry is a key subject in the CRC 1316 and will be strengthend by this measure in the upcoming years. (Image (c) hagenvontroja)
Plasma Trial Day - What is plasma and where does it find application in technology & research?
Interested high school students are invited to participate in the Plasma Trial Day on Jan. 28, 2020 from 10 a.m. to 3 p.m. online. The chairs of the Ruhr-Universität Bochum will introduce themselves.
Technical plasmas find their application in many areas of everyday life and enable many achievements of our engineered world, such as in microelectronics, optics or mechanical engineering. But also in areas like air purification, sterilization and medicine plasmas can be used effectively in innovative concepts.
The fundamentals of technical applications are our field of research. We work interdisciplinary with partners from research and industry to develop innovative concepts and systems. And we would like to explain to you the largely unknown concept of physical plasma and introduce you to how we use and research the "fourth state of matter". Furthermore, we would like to show you how you might become part of a research team in the future!
Project meeting 16./17.11.2020
Fall meeting of the consortium
The annual fall meeting of the CRC took place online to discuss the recent progress within the projects and their collaborations. Due to the online format it was easy to integrate the Mercator fellows into these discussions. The meeting was complemented by a small workshop on communication aspects related to gender issues.
Thomas Mussenbrock appointed at RUB
Since November 1, 2020, Prof. Dr. Thomas Mussenbrock has held the professorship for plasma technology at the Faculty of Electrical Engineering and Information Technology.
He conducts research on low temperature plasmas as well as on nanoelectronic and nanoionic components. His team develops analytical and numerical methods for modeling and simulation and applies them in interaction with experiments. "At the Ruhr-University Bochum, I find the ideal conditions for this," explains Thomas Mussenbrock. "Here, these experiments run right next door. I can follow them live and draw conclusions for our simulations, which in turn have a positive effect on the next experiments. In concrete terms, it is often a question of getting energy into a plasma efficiently and in a targeted manner. "Our goal is to excite only very specific particles." For Thomas Mussenbrock, much of his work revolves around the transport of energy and matter. "We want to understand the macroscopic behavior of the systems on the basis of the microscopic dynamics of the atoms, molecules, electrons and photons involved," the researcher explains.
In detail, plasmas play a decisive role in the manufacture of microelectronic components and circuits, for example. "More than 70 percent of all manufacturing steps are plasma-assisted," says Thomas Mussenbrock. "It is not for nothing that they say: No plasma, no iPad.
The chair of plasma technology is involved in two collaborative research centers among others. This research centers are the collaborative research center transregional SFB-TR 87 "Pulsed High-Power Plasmas for the Synthesis of Nanostructured Functional Layers," and the CRC 1316 "Transient Atmospheric Pressure Plasmas - from Plasma to Liquids to Solids,". Morevoer, Thomas Mussenbrock is also involved in the research group of the German Research Foundation FOR 2093 "Memristive Components for Neural Systems".
New in the team
Judith Golda appointed as assistant professor for plasma physics at interfaces
The members of the plasma research groups on campus welcome its newest member Jun. Prof. Dr. Judith Golda, who will take over the group "Plasma Physics at Interfaces" from 01.11.2020. Dr. Golda studied and received her doctorate in Bochum.
After several stays abroad, she was last employed as group leader at the Christian-Albrechts-University of Kiel. In her research, she focuses on the investigation of non-equilibrium plasmas and their interaction with surrounding media such as solids or liquids by means of numerous spectroscopic techniques. These topics are seamlessly embedded in the current SFB 1316.
Successful Plasma Summer School in 2020 in an online format
Due to the current situation, this year's summer school did not take place at the usual location of the physics center in Bad Honnef, but online. The regular programme consisting of basic plasma physics lectures combined with a master class on special topics could not take place as usual. Nevertheless, all teachers have agreed to deliver their basic lectures via an online video format. The summer school was extended to two weeks with two lectures per day. This year more people were able to tune in, because the online format is much easier to reach from regions with limited travel possibilities.
The lectures were technically flawless and the feedback from students and teachers was very positive. Many discussions and interactions could be made possible due to the high commitment of all teachers. Two practical workshops were also held by L. L. Alves on solving the Boltzmann equation and by N. Braithwaite on analyzing the Paschen curve.
We hope for another summer school in 2021, then again in the facilities of the physics center in Bad Honnef. The latest information on the planning for 2021 will be published at the summer school homepage in March 2021.
Great colloquium planned for April 2021
As MGK activity of the CRC 1316 for all PhD students as well as PostDocs of the collaborative research center, a colloquium taking place in a conference center is organized. The program is planned for two days in a conference center. The colloquium is in the frame of an informal format, so that intense discussion and questions can arise.
Associated PhD students or PostDocs from the SFB-TR 87 as well as collaborating institutes are welcome.
The colloquium is planned for 21/04/21 until 22/04/21 2021 in Maria in der Aue in Wermelskirchen.
Further information and the registration are realized via a separate page: MGK colloquium.
The organization is done by two Phd students from the CRC 1316, Jan Kuhfeld and Patrick Preissing. For questions, both can be contacted directly or via sfb1316(at)rub.de.
Successful collaboration with INP Greifswald
Research data management as central aspect within the collaborative research centres
Research data is a central output of science. They expand the scientific knowledge and are the basis for future research projects. The documentation of research data should follow subject-specific standards. The long-term archiving of research data is important for the quality assurance of any scientific work, but is also a fundamental prerequisite to allow the reusability of research results.
Researcher from the INP Greifswald enrolled a BMBF funded project with the title Quality assurance and networking of research data in plasma technology - QPTDat. This project aims to develop and test processes and methods for a quality assured and interdisciplinary reuse of research data from plasma technology.
A collaboration between INP and the CRC 1316 started in 2018 and now the Research Department Plasmas with Complex Interactions, and also the SFB-TR 87 join the activities on research data management. A workshop organized by INP Greifswald in January 2020 was the starting point for further active implementations in the field of research data management in the plasma community in the CRCs as well as in the Research Department.
First measures at EP2
As a first measure, an initiative at the research group EP2 at RUB results in an improved data storage on the local server of the institute. The storage volume has a regular backup and granting access to the complete group or to individual persons is possible. Beside measurement data, all further analysis steps are documented including meta data from all process steps. The members of the research group used a file name scheme, so that files can be found easily by other researchers.
Research data repository
Finally, published research data can be stored and published for the open public on the repository at
The idea of such a repository is the full documentation of measurement conditions (measurement data in a readable file format including meta data). First research groups from the CRCs have access to this repository and upload research data of published papers.
The concept of the repository is based on a multi-level system for publishing records. Users can put data online for review, which are then published by group moderators. The standards for publishing records must be defined by the group. In addition, meta data standards are currently being developed within the CRCs and together with INP Greifswald, so that data entry will be clearer and more uniform in future.
Recently, the Research Department Plasmas with Complex Interactions has started to join the collaboration of different scientific institutions within the so-called NFDI4Phys consortium. It aims to create structures and tools to simplify and unify the exchange of (mainly) numerical factual data in all areas of physics, with related disciplines and with the industry. The consortium is applying to the DFG for funding within the National Research Data Infrastructure (NFDI) project.
Within the framework of the NFDI4Phys consortium, the CRCs developing meta data standards for research questions in plasma science. Further goals are to contribute to the definition of basic and interdisciplinary standards and to develop methods to make research data from different sources generally accessible and interpretable.
Japanese core-to-core program
Two PhD students profit from research stay at Hamaguchi Lab, Center for Atomic and Molecular Technologies, Osaka University, Osaka
From October to December 2019, I was able to join the lab of Prof. Satoshi Hamaguchi at the Center for Atomic and Molecular Technologies in Osaka, Japan.
My field of research is applied microbiology and my focus is on biocatalytic reactions with non-thermal plasmas.
Using numerical simulations, I studied the propagation of plasma-induced reactive species in liquids to gain an insight on the depth of penetration and concentration of these species. This knowledge will help to understand the interaction between plasmas and enzymes that are studied in project B8 of the CRC 1316, specifically to protect the enzymes from inactivation and to drive biocatalysis.
The research stay in Japan was very helpful to deepen my knowledge for my main research question.
Abdulkadir Yayci, project B8 of the CRC 1316
I have visited Hamaguchi Laboratories at Osaka University in Japan for 3 months. The lab exchange was funded partially by the CRC-1316 and the JSPS core-to-core program. The group of Prof. Satoshi Hamaguchi developed a reaction-diffusion-convection simulation for the generation and transport of chemical species in water, introduced by atmospheric-pressure plasma. During my stay, I worked on a multiphase fluid model. The typical flow field of a turbulent atmospheric-pressure plasma jet in direct vicinity of a liquid was modelled by solving a k-epsilon turbulence model. A Volume-of-Fluid (VOF) method was applied for the coupled flow of gaseous and liquid phase. The simulations agree very well with experimental results in the literature. The results from the fluid flow simulations were integrated into the reaction-diffusion-convection equations to evaluate the influence of different flow regimes on the generation and transport of chemical species in the liquid.
At Bochum University, I am working as a PhD student within project B5 of the CRC 1316: 2D-plasma-liquid-solid interfaces – plasma electrolytic oxidation. The generated results can be useful for this project in regards of chemical species generation inside of liquids. In addition, the fluid flow model is interesting for other groups working with atmospheric-pressure plasmas (e.g. project B2: Self-organization of sub-µm surface structures stimulated by microplasma generated reactive species and short-pulsed laser irradiation).
Summarizing I can say, that I had a very pleasant stay in Osaka, that I personally enjoyed a lot. The cooperation with the Hamaguchi Laboratories were very fruitful and everyone was very kind during my stay.
