This session will focus on dissolution and degradation of glass and glass-ceramics in aqueous environments, including both longer time frame aspects of glass dissolution and the more immediate role of interfacial reactions between aqueous environments and glass (including hydrolysis reactions, cation inter-diffusion, and incorporation of water into the glass matrix). Studies which focus on glass surface and water reaction mechanisms, interfacial structures, and transport behaviors using either computational or experimental methodologies are particularly encouraged.

Elucidation of mechanisms and kinetics of glass degradation in studies conducted under various conditions are also welcome, for example those which investigate influence of solution composition, temperature, glass composition, reactive surface area, gel layers, secondary phases, environmental materials, and radiation on glass dissolution.
