Nanoionics – Fundamentals and Applications

Instructors:

Schedule

Sunday, 18 June; 13:35 - 15:25 in Room A5, Hall 7 of "Padova Fiere"

Tutorial Description

In many systems of interest the impact of interfaces is so large or the distance of neighboring interfaces so small that usual bulk considerations are not sufficient. This causes severe property changes that can be exploited as a powerful adjusting screw for materials research and application. This exciting subfield of solid state ionics has been termed “nanoionics”. After a short introduction into bulk charge carrier chemistry, concentration and mobility effects are discussed occurring at interfaces and in confined systems where the interfacial spacing may even give rise to mesoscopic phenomena. The last part of the tutorial deals explicitly with the application potential in terms of batteries, fuel cells, sensors and memristors.

Duration: 2 hours.

Registration: 150 Euros.

Tutorial Topics:

Joachim Maier studied chemistry at the University of Saarbrücken, received his doctorate there in 1982 and completed his habilitation at the University of Tübingen in 1988. He had or has been lecturing at Tübingen, at the MIT as foreign faculty member, at the University of Graz as visiting Professor and at the University of Stuttgart as Honorary Professor. As a director of the physical chemistry department (since 1991) of the Max-Planck-Institute for Solid State Research his main interest lies in the conceptual understanding of chemical and electrochemical phenomena involving solids as well as in the purposeful exploitation in terms of materials science.

Rotraut Merkle studied chemistry in Stuttgart. After a Diploma thesis in Theoretical Chemistry she received her PhD in Physical Chemistry. In 1998 she joined the department of Physical Chemistry at the Max-Planck Institute for Solid State Research in Stuttgart. Her research interests range from fundamental aspects of point defect formation and transport in ionic solids to detailed investigations of reaction kinetics at oxide surfaces (applying preferentially in situ methods), and extend also to solid oxide fuel cells, gas sensors and heterogeneous catalysis.
