MARC VAN DER SCHANS
Marc van der Schans from the Department of Applied Physics, Elementary Processes in Gas discharges (EPG) at the TU Eindhoven (Netherlands) is visiting PhD student Patrick Böhm (Experimental Physics V) during the week of July 27-31, 2015. The goal of the collaboration includes the application of the electric field measurement technique, which will be further developed by Patrick Böhm in the context of his PhD thesis at Ruhr-Universität, to a plasma bullet discharge, which will be further developed and extensively analyzed by Marc van der Schans, also in the context of his PhD thesis. In case of positive results, the results will even lead to the construction of a corresponding setup at the TU Eindhoven, whereby the rarely represented electric field measurement technique, also known as "E-CARS", would find another application site.

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.

PROF. DR. YURI LITVINENKO
Prof. Dr. Yuri Litvinenko from the University of Waikato, Hamilton, New Zealand will be visiting the Chair of Space and Astrophysics (Theoretical Physics IV) from 01.12.2015 to 26.02.2016. His stay is funded by the Research School PLUS in the program "Visiting Research Professor" (VIP) through an award applied for by Prof. Dr. Reinhard Schlickeiser and PD Dr. Horst Fichtner. This support will also be used for further longer visits in the period until November 2017.

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!
