Four research members of the CRC 1316 join the 9th International Conference on Plasma Medicine (ICPM9). Today, Sebastian Burhenn talked about the 'Impact of humidity on the OH distribution in the effluent of the COST-Jet measures by laser induced fluorescence'. Another highlight is the plenary talk of the CRC PI Julia Bandow on 'Plasma-driven biocatalysis: challenges and opportunities'.
The 49th International Conference on Plasma Science (ICOPS) was held in Seattle from May 22 through May 26. It was one of the first conferences since the beginning of the COVID pandemic situation that was organized as a hybrid conference and partly held on site. It was nice to be back at a live conference getting in touch face to face with other researchers. More than 350 on site attendees visited the conference and more than 150 researchers joined the conference virtually. The conference venue was the Sheraton Grand Seattle located in Seattle Downtown. The scientific program reached out to wide varieties in the field of plasma physics covering topics such as basic phenomena in high temperature fusion plasmas or low temperature plasma jets up to the applications of different sources as for example in medicine, agriculture or for environmental purposes.
Beside the scientific program there were lots of things to discover around the area such as strolling at the famous Pike Place Market or going up the Space Needle to get a great view over the city and the 4392m high volcano Mount Rainier, if it does not hide itself in dense clouds. During the conference a spontaneous group event took place, exploring the night life of Seattle together with around 30 other researchers and the conference was eventually closed with a nice banquet.

The participants of the lecture "Plasma Diagnostics" from this and previous semesters visited the company Avantes in Apeldoorn, NL on 3.6.22. The Dutch company is specialized in so called hand-held or USB spectrometers and related accessories. These spectrometers are popular for species identification but also for monitoring plasmas.
During the from the Faculty of Physics and Astronomy supported excursion, insights into the production and new developments were given in addition to further application possibilities. In two small workshops, current plasma-relevant diagnostics could be used live, namely Raman spectroscopy and laser-induced breakdown spectroscopy (LIPS), which directly closed the circle to the lecture.
Students from the Faculty of Physics and Astronomy who are writing their theses as part of CRC 1316 participated in the trip.
The paper: "Propagation of nanosecond plasmas in liquids—Streamer velocities and streamer lengths" Journal of Vacuum Science & Technology A 40, 043003 (2022); had been selected as editors pick.
An Erasmus program enables exchange among university staff. RUB welcomes guests from the University of Oulu.
RUB receives a visit from Finland. The Erasmus+ Staff Mobility Program enables visits of university staff to expand internationalization. From the UNIC partner university Oulu in Finland, researchers from different faculties are visiting RUB to exchange ideas on research data management.
On May 11, 2022, the so-called Data Stewards will be welcomed at an event hosted by RUB, the University of Duisburg Essen (UDE) and the Technical University (TU) Dortmund at the Event Center on campus. The Data Stewards are responsible for the Faculty of Education, Oulu Business School, Faculty of Humanities, Faculty of Technology and Faculty of Science and Biocenter Oulu.
The participating guests are Data Stewards from various collaborative projects, personnel from the libraries and central IT, and interested researchers from the three universities of the University Alliance Ruhr. In addition to the RUB, these include the UDE and TU Dortmund. On May 12, the program for the Finnish guests will also include one-on-one discussions and roundtable discussions in smaller groups. These include, for example, laboratory tours of the Collaborative Research Centers "Extinction Learning" (SFB 1280) and "Transient Atmospheric Pressure Plasmas - from Plasma to Liquids to Solids" (SFB 1316), a discussion round on the topic of Open Science and talks with the University Library, the WORLDFACTORY Start-up Center and the Materials Research Department.

Achim von Keudell became with the beginning of March one of the four Editors in Chief of Plasma Processes and Polymers.
With the start of the second funding period, all PhD students of the projects within the CRC 1316 were invited to participate in the annually MGK colloquium. The colloquium was held online at 7th and 8th of March 2022 and was organized by Maximilian Klich (project A8) and David Schulenberg (project A4).
The colloquium served as an introduction of the many new PhDs joining the CRC 1316 in its second funding period. Without the participation of project leaders it achieved a casual atmosphere for sharing scientific knowledge and interests between the PhD students. Here, they could introduce themselves and their projects as well as give a short summary about their projects achievements and future plans through talks or a poster presentation. Leading the talks regarding the different research topics modelling, DBD/RF discharges and plasma in liquids were the invited speakers which generated a well rounded experience.
The new funding period also required a few elections, namely the position of the PhD speaker formerly held by Maximilian Klich, as well as a position in the CRC 1316 gender board held by Lars Schücke (project A7) and Katharina Grosse (project B7). The newly elected PhD speaker is David Schulenberg and Stefanie Bogenrieder (project B4) as well as Lukas Forschner (project B12) are the new gender board representative.

A team of researchers from the Department of Interfacial Sciences at FHI Berlin has discovered how changes in the structure of copper catalyst particles during electrochemical CO2 reduction affect their catalytic performance. This should lead to the development of new catalysts that convert the greenhouse gas CO2 into useful chemicals. Researchers around CRC member Philipp Grosse from project B1 published their work in the journal Nature communications.
The could show how the initial number of catalysts particles, their size and density on the support electrode surface is not a reliable indicator of the actual number of particles present during reaction. More importantly, Philipp Gosse and colleagues show that by optimizing the design of the pre-catalyst structures, the structural evolution under working conditions is influenced and thus also their selectivity. This is also important for the electron microscopists.
A plasma workshop will take place with a special lecture on electrolysis, focusing on future energy scenarios, by Marcel Fiebrandt from Thyssengas on the 25th of February at 10:00.
The EU's Green Deal and the German Federal Climate Protection Act, adapted in 2021, set the ambitious goal of achieving greenhouse gas neutrality by 2050 and 2045, respectively. The necessary transformation of the world's fourth-largest economy toward climate neutrality requires massive adjustments in all sectors and energy carriers as well as in the energy infrastructure. In the national and European hydrogen strategy, hydrogen in combination with renewable energy sources is assigned a central role for the transformation of the European energy system. This is the case as the properties of hydrogen are able to complement the increasing electrification of the sectors. For example, hydrogen can be stored in large underground caverns, transported in pipelines and used for power generation when renewable energy generation is insufficient, and it provides decarbonization opportunities in applications that cannot or are difficult to decarbonize through direct electrification. As a result, power-to-gas-systems, and especially electrolysers, will play a key role as the interface of electricity and gas infrastructure in the future integrated energy system to couple both energy carriers. In this talk, a brief overview of the future energy system scenarios and their implications on the industrial, mobility, and heating sector will be given. Afterwards, the options of producing hydrogen will be discussed and which requirements they have to fulfil to be integrated effectively and economically in the future energy system. Due to their critical role at the interface of the power and gas grid, special attention is paid to the technical requirements based on the properties and restrictions of the energy grid.
