Front Cover: The Intrinsic Structural Resistance of a Grain Boundary to Transverse Ionic Conduction (ChemElectroChem 23/2020)

ChemElectroChem, vol. 7, pp. 4690

Abstract

The Front Cover illustrates oxide ions moving from one crystal grain across a grain boundary to an adjacent grain in a polycrystalline oxide-ion conductor. The mobile ions perceive the boundary as an additional resistance, arising from the disruption of the crystal structure at the boundary. The resistance can be tuned by applying high electric fields. More information can be found in the Communication A. R. Genreith-Schriever et al.
