Jana Parras won a prize at the „EMRS 2018“ in Strasbourg, France, for her poster presentation
titled „Is ReO3 a mixed ionic-electronic conductor? A DFT study of defect formation and migration in a B VIO3 perovskite-type oxide“.
The front cover of the journal Physical Chemistry Chemical Physics shows current research results from Dr. Julius Koettgen, Dr. Steffen Grieshammer, Philipp Hein and Prof. Dr. Manfred Martin. In the highlighted Perspective article “Understanding the ionic conductivity maximum in doped ceria: trapping and blocking” (DOI: 10.1039/C7CP08535D), ionic conductivity in doped ceria is systematically predicted. For this purpose, only a few migration energies from first-principles DFT calculations are combined with Kinetic Monte Carlo simulations. The resulting ionic conductivity is in agreement with experiments. The effect of dopants on migration barriers is separated in symmetric (blocking) and asymmetric influences (trapping). Blocking determines the dopant fraction where the ionic conductivity exhibits the maximum. Trapping limits the maximum ionic conductivity value.
Dr. Alexandra von der Heiden won a prize at the 21st International Conference on Solid State Ionics in Padua, Italy, for her poster presentation titled „Influence of structure and stoichiometry on oxygen diffusion and conductivity in gallium oxide thin films“.
Priv.-Doz. Dr. Roger A. De Souza was appointed an Extraordinary Professor at RWTH Aachen University on 01.02.17 .

Helmholtz Institute Münster Ionics in Energy Storage
The Helmholtz Institute Münster for Ionics in Energy Storage, IEK-12, was founded in July 2014. It is run as a branch office of Forschungszentrum Jülich together with the University of Münster, WWU, and RWTH Aachen University. IEK-12 is concerned with researching electrolytes as a key component for new battery concepts. The electrolyte is a central part of any battery and is crucial for making the use of renewable energy sources cheap and widely available, thus successfully transforming the German energy sector.
Dr. Roger A. De Souza has been appointed a Visiting Associate Professor at Stanford University in the Department of Materials Science and Engineering, Stanford University.
Durch Europäische Union gefördertes Verbundprojekt "Green-CC" bewilligt
Funded by the European Union under the 7th Framework Programme Collaborative the Project GREEN - CC : " Graded Membranes for Energy Efficient New Generation Carbon Capture Process " dedicates its research on supported thin film ceramic gas separation membranes with complex support microstructure . The aim of the four-year research work is to increase the separation efficiency significantly through the use of extremely thin membrane layers on top of a porous support and the use of catalysts for accelerating surface exchange reactions. Our Institute is part of the research network on oxygen transport modeling of supported thin film membranes. In addition, the stability and performance of oxygen transport membranes is tested in a laboratory scale with model gases containing flue gas components such as CO2 and SO2.
