MAE MOURNS LOSS OF PROFESSOR WALTER LEMPERT
The Research Department Plasma is deeply saddened by the passing of Prof. Walter Lempert on April 11, 2015. He collaborated closely for many years with Prof. Uwe Czarnetzki and his group at EP5. He will be greatly missed.
"The department was deeply saddened by the passing of Walter Lempert on April 11, 2015.
Lempert was a faculty member in the Department of Mechanical and Aerospace Engineering and co-director of the Non-Equilibrium Thermodynamics Laboratory (NETL), a major research laboratory containing state-of-the-art computational and experimental facilities among the most advanced at any U.S. university.
The NETL thrust area is energy, fluid and thermal systems, studying effective fuel use, reduced emissions, improved performance and cost effectiveness – critically important industrial and societal goals. Lempert and his colleagues led research and education focused on analytical, computational and experimental techniques for achieving these goals.
Lempert’s primary research was on the application of atomic and molecular spectroscopy to problems of engineering interest, inherently interdisciplinary, combining such diverse subjects as nonlinear optics, fluid mechanics, plasma physics and energy transfer. He is a notable author of numerous publications, papers and presentations helping to enhance the department’s reputation in energy, fluid and thermal systems.
Lempert left an indelible mark at Ohio State and a legacy of dedicated excellence in education and research. His cheerful personality, friendliness and warmth among faculty, staff and students will be greatly missed."

INTERNATIONAL CONFERENCE ON METALLURGICAL COATINGS AND THIN FILMS (ICMCTF)
The International Conference on Metallurgical Coatings and Thin Films (ICMCTF) is internationally recognized as the premier international conference focused on thin-film deposition, characterization, and advanced surface engineering. It brings together scientists, engineers, and technologists from academia, government laboratories, and industry, thereby merging cutting-edge research with real-world applications. The conference consistently draws more than 700 attendees each year within 37 oral technical sessions and a well-attended poster session.
It took part in San Diego from April 20th-24th, 2015. Postdoc Dr. Ante Hecimovic (Experimental Physics II) gave a presentation entitled "Plasma oscillations and ion transport in DC and HiPIMS magnetron discharges". He was also a session chair on a topical symposia "Plasma diagnostic and modelling". At the end, he has organised a round table disccusion on "Plasma diagnostic and modelling techniques for improved understanding of deposition process".
Prof. Dr. Peter Awakowicz and his PhD student Stefan Ries participated at ICMCTF as well.

ÉCOLE DE PHYSIQUE DES HOUCHES: FUNDAMENTALS OF AERODYNAMIC FLOW AND COMBUSTION CONTROL BY PLAMAS
Dr. Volker Schulz-von der Gathen (EP2, RUB) gives a talk about "Dynamics of the discharge evolution of micro discharge arrays" at the École de Physique des Houches in France (from April 12, 2015 to April 17, 2015).
This conference is the fifth of a cycle of conferences dedicated to the fundamental issues in the scientific disciplines relevant to aeronautics and space development. The previous editions of this workshop were held in Villa Monastero, Italy (2007), Les Houches (2009 & 2011) and Aussois (2013). The program will feature twenty invited lectures. Presentations will again address fundamental issues, experimental challenges, measurement methods and advanced numerical simulation.
The conference is managed by a team from the Paris region, with Svetlana Starikovskaia (Chairperson, Laboratoire de Physique des Plasmas, Ecole Polytechnique), Christophe Laux (vice-Chair, Ecole Centrale de Paris), Jean-Pierre Taran (local organisation, Onera) and a Steering Committee composed of leading scientists in the field.
The program of invited lectures can be found here.

MOHAMED MOKHTAR HEFNY AND JUN.-PROF. DR. JAN BENEDIKT VISIT TO INSTITUTE OF PLASMA PHYSICS (IPP) IN CZECH REPUBLIC
PhD student Mohamed Mok
htar Hefny went to Prague from March 02, 2015 to March 20, 2015 with his supervisor Jun.-Prof. Dr. Jan Benedikt. He visited the group of Dr. Petr Lukes, Institute of Plasma Physics (IPP) in Czech Republic. This scientific mission was within the COST action "TD1208 Electrical discharges with liquids for future applications" and STSM Topic was "Chemical analysis of the reactive species produced in water treated by plasma produced radicals or VUV photons" and its Reference Number is "COST-STSM-ECOST-STSM-TD1208-020315-056481". They used the microscale atmospheric pressure plasma jet in treating water and analyzed the reactive species after treatment using ion and liquid chromatography and spectrophotometric. they used the micro-APPJ to generate a remote cold plasma at atmospheric pressure above the treated liquid in a He controlled atmosphere, they designed for that a small reactor with putting 3 ml of the prospective treated water inside it and making the plasma 4 mm above it. Treatment of water have done by many gas mixtures like He, He with O2 and He with N2 with and without water vapor. During the STSM they focused on the study of aqueous-phase chemistry of reactive oxygen species (ROS) and reactive nitrogen species (RNS) generated by plasma jet in the treated water. they made a lot of studies of H2O2, NO2-, NO3- synthesize in the treated water, they also studied the reaction pathways of phenol degradation induced by plasma in deionized water and used the phenol as a chemical probe.

TET
PROF. DR. JULIAN SCHULZE
From March 23 to 27, Prof. Julian Schulze from West Virginia University, USA, visited the Chair of Theoretical Electrical Engineering at Ruhr-Universität Bochum. The focus was on the scientific exchange with the chairs AEPT and TET as well as the work with Sebastian Wilczek, PhD student, on the common research topic. The research cooperation between the two universities in the field of plasma technology will be further expanded and consolidated in the future. Prof. Schulze studied, received his doctorate and habilitated at the Ruhr-Universität Bochum. As a promising young scientist in the field of low-temperature plasma physics, he was already awarded the Hans Werner Osthoff Plasma Physics Prize in 2012.
The scope and outstanding quality of his work in the few years from physics diploma to doctorate to habilitand at the Institute of Experimental Physics V of the RUB was impressive. His experiments have significantly advanced the understanding of the physics of high-frequency discharges. After a short period as a post-doc at the Hungarian Academy of Sciences, he is now Assistant Professor at West Virginia University and is considered a world-renowned expert in the field of RF plasmas. Together with Sebastian Wilczek, Prof. Schulze studies the heating/dynamics of electrons in low pressure capacitive discharges. This heating mechanism has a crucial influence on the plasma composition and needs to be understood in order to control industrial coating and etching processes much better. Based on previous collaborations, an article on the confinement quality of high-energy beam electrons was published in March 2015. The collaboration will continue in the future. In the summer semester, Prof. Schulze offers a block seminar over five days for students and interested parties. With his visit to the RUB, further interesting topics in plasma technology were discussed and investigated. Joint publications are planned.
