The 19th Edition of the International Symposium on Intercalation Compounds (ISIC19) will focus on the peculiar properties of intercalation materials. These solids have experienced a great development in recent years and represent now an established specific domain of solid-state research and materials sciences. The design and the characterization of intercalation compounds with advanced functional properties needs of interdisciplinary competences such as chemistry, solid-state physics and biology. This Symposium offers a unique opportunity for the Intercalation Compounds Community to bring together information, results and ideas that will stimulate further exploration in the filed of the intercalation compounds.
