Award

Prof. Uwe Czarnetzki awarded International Fellow of the Japan Society of Applied Physics

Prof. Uwe Czarnetzki from project A1/A2 of the CRC 1316 was awarded international fellow of the Japan Society of Applied Physics. The award ceremony will be held September 18th, 2019 during the Japan Society of Applied Physics autumn meeting. During the ceremony, the honored fellows are invited to present their scientific contribution. The status of international fellows of the Japan Society of Applied Physics is an honor awarded to scientists who support the progress of the Japan Society of Applied Physics in recognition of their achievements. Congratulations!

Conference organization

Successful Frontiers conference in Bad Honnef

Between May 12th and May 16th, 2019, the 13th Frontiers in Low-Temperature in Plasma Diagnostics and 1st Frontiers in Low-Temperature Plasma Simulations was held in the Physikzentrum in Bad Honnef.

The conference was organized by the Research Department Plasmas with Complex Interactions and chaired by Prof. Czarnetzki from the SFB 1316. In total, 103 participants joined the diagnostics and simulation meeting.

Scientists from both collaborative research centers, SFB TR 87 and SFB 1316, attended the meeting and presented five poster and four oral contributions. Julian Held, PhD student in project A5 of the SFB-TR 87, was awarded the prize for the best oral presentation with his contribution Velocity distribution function of atoms and ionsin HiPIMS by Doppler broadening of optical emission lines during the conference. Congratulations to him!

Public relations

Teenagers enjoy plasma physics 

During the Easter holidays the Schülerprojektwoche for 14 and 15 year old pupils took place at the Ruhr-University Bochum. The Schülerprojektwoche is an established part of public relations for pupils and is, belong others, financed by both SFBs. 

For one week 60 girls and boys did experiments in four different workshops, namely “astronomy”, “plasma physics”, “energy efficient house building” and “physics in medicine”. 

In the plasma project, which was supervised by PhD and Master students of both SFBs, the pupils deposited thin gold layers on glass substrate using a plasma coater. Additionally, they characterized different samples regarding thickness, optical transmission and conductivity in dependence of the plasma deposition time.

Besides the workshops, the girls and boys experienced university life. They attended a lecture, visited “real” physics laboratories and watched a show at the planetarium in Bochum.  At the end of the 4 days, they created posters and presented their results of the workshops to the other pupils during a poster session. 

The Schülerprojektwoche was successfully finished with a quiz duel about the learned physics between the four workshop groups. Here, the plasma physics group won and was awarded with a cup. 

Press releases

New class of catalysts for energy conversion

© RUB, Marquard

The research group of Prof. Ludwig and his colleagues recently published their new results in the catalyst production. “At our department, we have unique methods at our disposal to manufacture these complex materials from five source elements in different compositions in form of thin film or nanoparticle libraries,” explains Professor Alfred Ludwig from the Chair of Materials for Microtechnology at RUB. The atoms of the source elements blend in plasma and form nanoparticles in a substrate of ionic liquid. If the nanoparticles are located in the vicinity of the respective atom source, the percentage of atoms from that source is higher in the respective particle. “Very limited research has as yet been conducted into the usage of such materials in electrocatalysis,” says Ludwig.

Lab visit

Dr. habil. Sedina Tsikata visits plasma labs in Bochum

Within the frame of the physics collquium at Ruhr University in Bochum, Dr. habil. Sedina Tsikata from CNRS Orléans, France was invited to present her reserach topic. Her presentation had the title "With plasmas into space - physics of Hall thrusters". The visit was also used to discuss recent research topics with the groups of Prof. A. von Keudell and Prof. U. Czarnetzki.

Language course

PhD students enhance their English skills

In February, 8 PhD students of both SFBs, SFB-TR87 and SFB 1316, attended a language school in London for one week. The focus of this week was "presenting in English".  In small groups of 4 PhD students with one teacher each they learned a lot about structuring a successful presentation and delivering arguments clearly and convincingly. Besides studying English phrases for presentations and leading discussions, they also discussed rhetoric and body language. By giving many prepared and spontaneous talks in the class, they applied directly what they have learned. 

During the week they deepened their knowledge not only in presentation skills, but also in British culture and literature by reading common novel paragraphs such as Oscar Wilde.  


Besides the English workshop the group enjoyed the stay in London and went for example to the musical Alladin and visited the British museum and the Tate modern. All in all, it was a successful week and the Phd sstudents from Bochum, Aachen, Cottbus, and Paderborn are grateful for the opportunity and support by the SBFs for this workshop.

MERCATOR FELLOWS

New Mercator fellow of the SFB 1316 - Prof. Dr. Satoshi Hamaguchi, University of Osaka

Prof. Satoshi Hamaguchis research focus on plasma-material interactions in general, including their industrial applications. The aim of research is to understand fundamental mechanics of plasma-material interactions under various conditions. To achieve this, we combine plasma/beam experiments with numerical simulation/modeling. More specifically our current research topics include 1) etching, deposition, and surface modification processes for micro/nano electronics device manufacturing, 2) surface modification and functionalization of biomaterials by plasmas, 3) processing of water and biological systems by atmospheric-pressure plasmas mainly for applications in plasma medicine and plasma agriculture, and 4) dynamics and chemical reactions in plasmas under various conditions, including atmospheric-pressure plasmas.

Prof. Hamaguchi is also coordinator of the JSPS core-to-core program "Establishment of the Center for Collaborative Research in Data-Driven Plasma Science " that connects Osaka university with Ruhr University Bochum, and the universities in Bologna, Aix-Marseille, and York. In the framework of this program the sending side covers international airfare and the receiving side covers maintenance and the domestic travel costs. The hosting side covers the cost of holding the seminars.

Lab visit

Visit to the GREMI (Université d‘Orléans, France)

Sylvain Iseni, Volker Schulz-von der Gathen and Simon Kreuznacht laser safe at the experiment

From 18. to 28.02.2019 Simon Kreuznacht and Dr. Volker Schulz-von der Gathen visited Dr. Sylvain Iseni within the long term cooperation with the group of Remi Dussart at the GREMI – a CNRS instute located at the University of Orléans. During that stay they prepared a laser diagnostic measurment of the gas temperature very close to the surface of a DC driven micro-cavity discharge array.
