21.11.2012 - VISIT TO UNIVERSITY OF MINNESOTA, MINNEAPOLIS, USA
From 5th to 10th of November 2012, Dr. Ilija Stefanović has visited University of Minnesota, Department of Mechanical Engineering. During his stay he visited labs of Prof. U. Kortshagen (Si nanoparticle formation form low pressure, low temperature plasma), Prof. S. Girshik (nanoparticle formation form high pressure plasmas), Prof. D. Pui (aerosol production, filtration and separation) and Prof. P. McMurry (theoretical and experimental studies of aerosol systems and aerosol instrumentation).
He also reported about research on nanoparticle polymerization in low temperature RF plasmas in Research Department “Plasmas with Complex Interactions”. The future collaboration on nanoparticle sampling form atmospheric pressure microplasma has been discussed.
The Department of Mechanical Engineering of University of Minnesota is the world top institute for aerosol sampling and instrumentation. Beside of that, there is several plasma techniques developed for production, processing and handling of nanoparticles for industrial applications.

01.10.2012 - VISIT OF DANIEL SCHRÖDER AT THE YORK PLASMA INSTITUTE
From September 23rd to September 26th, 2012, PhD-student Daniel Schröder from project A1 visited the group of Professor Timo Gans at the University of York. His group is investigating the physics of low temperature plasmas at low and high pressures and is resident at the York Plasma Institute.
Within the already well-established cooperation, common experiments in the field of high pressure micro-plasmas for bio-medical applications have been planned. Complementary laser-based diagnostics together with optical emission spectroscopy are used to develop a deeper understanding of the production of reactive species in jet-like discharges and their interaction with biological materials. A return visit is planned for spring 2013.

24.09.2012 - DR. VOLKER-SCHULZ VON DER GATHEN AN DER GREMI / ORLÉANS
Dr. Volker Schulz-von der Gathen war vom 9. bis 21. September 2012 an der GREMI (Groupe de Recherches sur l'Energetique des Millieux Ionises) der Université d'Orléans, Frankreich. Er hat dort im Rahmen des PROCOPE-DAAD-Austauschprogramms gemeinsam mit Dr. Remi Dussart und Mukesh Kumar Kulsreshath gearbeitet.
Belgrade
18.06.2012 - VISIT AT CENTRE FOR NON EQUILIBRIUM PROCESSES IN BELGRADE
From May 3rd to 12th, 2012, Dr. Ilija Stefanovic and PhD student Thomas Kuschel visited their cooperation partners Dr. Dragana Maric and Prof. Zoran Lj. Petrovic at the Centre for Non Equilibrium Processes in Belgrade (Serbia). During this time, the team focused on a model which was developed by Phelps and Petrovic for standard size parallel plate dc discharges (discharge gap d = 1 cm) and modified it for the micro discharges. The model and the experimental results (measured in Bochum) agree very well as shown in the figure.

16.05.2012 - SARA GALLIAN VISITED PROF. HITCHON AND PROF. KUSHNER
During the last week of April, Sara Gallian, research assistant at TET Institute working in the SFB-TR 87 framework, has visited Prof. Hitchon and Prof. Kushner to discuss on the simulation of the HPPMS process. Nick Hitchon is a Professor at the University of Wisconsin-Madison and an expert in the field of kinetic plasma simulations. He is cooperating with the TET group on the phenomenological modeling of the recently observed rotating instability during the HPPMS operation. Mark Kushner is a Professor at the University of Michigan and is head of the Computational Plasma Science and Engineering Group (CPSEG) in the Department of Electrical and Computer Engineering. Prof. Kushner is a well known expert in the field of Hybrid Modelling and the main developer of the Hybrid Plasma Equipment Model (HPEM). HPEM is a comprehensive modeling platform for low pressure plasma processing reactors, capable of addressing Magnetron sputter and Ionized Metal Physical Vapor Deposition (IMPVD). During the visit, it was discussed the possibility use HPEM in the preliminary simulation of the HPPMS discharge.

10.04.2012 - JENNIFER STEPANEK IN MICHIGAN
Doktorandin Jennifer Stepanek aus der Nachwuchsgruppe Mikrobielle Antibiotikaforschung von Jun.-Prof. Julia Bandow ist vom 28.01. bis zum 27.04.2012 zu Gast bei Prof. Jakob im Department of Molecular, Cellular, and Developmental Biology der University of Michigan. Im Rahmen der Forschung für das Research Department „Plasmas with Complex Interactions“ untersuchte sie im Jakob Lab die Wirkung von Plasma auf das Protein Hsp33. Dabei zeigte sich eine Induktion der Chaperon-Aktivität von Hsp33 durch die Plasmabehandlung.

08.03.2012 - RÜDIGER REUTER AN DER PAUL-SABATIER UNIVERSITÄT IN TOULOUSE
Vom 6.2. bis 2.3.2012 war Doktorand Rüdiger Reuter zu Gast an der Paul-Sabatier Universität in Toulouse (Frankreich). Am Laboratorie Plasma & Conversion d’Energie (Laplace) untersuchte er in der Gruppe von Nicolas Gherardi die Abscheidung dünner Siliziumoxid Schichten durch eine DBD Entladung. Eine Beschichtung Monolage für Monolage, wie sie auch in an der Ruhr-Universität in den Arbeitsgruppen Gekoppelte Plasma-Festkörpersysteme und Reaktiver Plasmen in der DFG Forschergruppe 1123 durchgeführt wird, wurde auf eine DBD Entladung übertragen und erfolgreich zum Abscheiden kohlenstofffreier Schichten angewendet.
