专题:Thermal Expansion and Ionic Conductivity

This cluster of papers focuses on the phenomenon of negative thermal expansion in various materials, including perovskites, framework compounds, and antiperovskite compounds. It explores the mechanisms, controllability, and technological applications of negative thermal expansion, as well as its correlation with superconductivity and magnetic properties. Additionally, it discusses the development of sodium-beta alumina batteries and the associated challenges and perspectives.
