本交叉學科期刊致力于固體的物理、化學和材料科學的擴散、質量傳輸和反應性。每期的主要部分是關于下列各項的文章:固體缺陷的物理和化學;固體內部和對固體的反應，例如插入、腐蝕、氧化、燒結;離子輸運測量、機理和理論;(四)固態電化學;(v)離子-電子混合導電固體。還包括了相關的技術應用，只要用基本的固態特性來解釋它們的特性。歡迎提交檢討文件及有關的研討會記錄。

This interdisciplinary journal is devoted to the physics, chemistry and materials science of diffusion, mass transport, and reactivity of solids. The major part of each issue is devoted to articles on:(i) physics and chemistry of defects in solids;(ii) reactions in and on solids, e.g. intercalation, corrosion, oxidation, sintering;(iii) ion transport measurements, mechanisms and theory;(iv) solid state electrochemistry;(v) ionically-electronically mixed conducting solids.Related technological applications are also included, provided their characteristics are interpreted in terms of the basic solid state properties.Review papers and relevant symposium proceedings are welcome.
