Several topics ranging from crystalline ionic conductors, glasses, polymeric materials to proton conductors are discussed. Characterization techniques such as NMR and XPS and synthesis techniques such as sol-gel are emphasized. Some coverage of superconductors is also included. The proceedings of such an interdisciplinary conference would not be complete without a discussion on applications. Results based on the fabrication of fuel cells, solid state batteries, sensors and electrochromic displays are therefore presented.
