Front Cover: Development of a Core–Shell Heterojunction TiO ₂ /SrTiO ₃ Electrolyte with Improved Ionic Conductivity (ChemPhysChem 11/2022)

The Front Cover shows the built-in electric field created by the semiconductor heterostructure that confines the proton transport on the surface layer of the nanocomposite core–shell heterostructure imparting faster ion transport and lower activation energy.
