DR. QING XIONG
Dr. Qing Xiong, researcher and Assistant Professor from College of Electrical Engineering, Chongqing University, China, gives a talk about "Atmospheric Pressure Micro-plasma Jets and Glow Discharge with Water Electrode". It will be on July 15th, 2015, at 10:15 am at NABF05/694. Anybody interested is welcome to join.
Dr. Qing Xiong will be visiting Prof. Dr. Uwe Czarnetzki at Experimentalphysics V. His research interests mostly focus on advanced spectroscopic diagnostic of cold atmospheric pressure plasmas and plasma interacting with liquids.
Abstract: Non-equilibrium atmospheric pressure micro-plasma jets have recently obtained increasing attention for their unique features such as chamber-less operation and enhanced chemistry without elevated gas temperature. These attractive features make them prospective in several emerging novel applications, such as bio-medicine, material synthesis and surface modification. Characterizations and control of these micro-discharges are important, especially their physics and chemistry, to get insights into mechanisms of plasma treatments. On the other side, plasma interacts with liquid are common in plasma in liquid or in contact with liquid, but interaction processes are very complicated. Until now the fundamentals of interactions between plasma and liquid still remain open with a lot of indistinct issues. Important questions about how the plasma affects the liquid chemistry, and meanwhile how the liquid influences the chemistry of plasma, need to be answered.
These are the main background of my talk, and I will report the characterizations of atmospheric pressure micro-plasma jets, include their physics and chemical features based on plasma diagnostic (OES, LIF, etc). Meanwhile, the presentation will report my recent result of OH radicals production in a glow discharge in contact with water, based on broadband UV absorption spectroscopy measurements. Production mechanism of OH radicals in the discharge above water will be discussed.

SCHÜLERPRAKTIKANT JAKOB RAFFLER
Within the framework of the Austrian Matura (high school diploma), a pre-scientific paper is required. Jakob Raffler, student at the Bundesrealgymnasium GRG 23 Altererlaa, Vienna also supervised by Renate Stingl writes in his thesis about "Research on pulsed high power plasmas at the Ruhr-Universität Bochum". In order to get first-hand information, he is therefore a guest at the SFB-TR87 for one week (6.7.-10.7.2015) and together with Christian Maszl (Project C3, Institute of Experimental Physics II) is working both experimentally and theoretically on plasmas and their applications. In March 2016, he will hand in his work and give a presentation at his school. We wish him a lot of fun in Bochum and success with his work!

SUMMER SCHOOL ON PLASMA CHEMISTRY
From 2 to 4 July 2015, DIFFER hosted 40 students, PhD candidates and post-docs in a summer school on plasma chemistry as part of the 22nd International Symposium on Plasma Chemistry. The summer school programme concentrated on the basics of plasma physics and chemistry and its application. Expert courses and workshops delved into plasma physics, plasma chemistry, plasma sources and applications from thermal to non-equilibrium plasma technology. Prof. Dr. Achim von Keudell and Dr. Volker Schulz-von der Gathen (both from Experimentalphysics II, RUB) gave talks at this school.

DR. MAHDI SHIRAZI
Dr. Mahdi Shirazi from Universiteit Antwerp is a Marie Curie ITN RAPID fellow and gives a presentation during his secondment at the Ruhr-University Bochum on Monday, June 29th, 2015 at 9:15 am, NB 5/158 (Seminarraum EP2). His talk is about Multi-scale modelling of plasma catalysis.
n this research, the interaction of free radical species with a Ni catalyst surface were studied by density functional theory (DFT) calculations, and this information is now being implemented in a kinetic Monte Carlo model, to study the catalytic mechanisms.
He comes from the research group PLASMANT. The research group is part of the chemistry department, and belongs to the center-of-excellence NANO of the University of Antwerp. The group specialized in computer modeling of plasmas and plasma-surface interactions, for applications in material science, the microelectronic, medical and environmental applications (plasma catalysis).
Anybody interested, is welcome to join!
