Abstract submission:


Solid State Ionics is the field devoted to the study of ion transport and reactivity in the solid state. It has a long and illustrious history, which started with the studies of Michael Faraday and which was set on a firm foundation by the fundamental work of Nernst, Frenkel, Schottky and Wagner. Since those beginnings, interest in the subject has increased continuously, with a focus on materials for solid oxide fuel cells, lithium batteries and sensors. In the last twenty years or so, there have been several surprising developments in the field, not only in terms of the materials systems that are attracting attention, and in terms of possible applications, but also in terms of new and improved methods of investigation, both experimental and computational. This Bunsen colloquium will provide a forum to discuss the latest developments in the field of Solid State Ionics and to examine the prospects for the future. In addition, the convergence of solid state ionics and solid state electronics will be discussed. The Colloquium will also include an extended Poster Session. We look forward to contributions from national and international participants.
