Chapter Two – Diffusion in Nanoporous Host Systems

摘要: Abstract Diffusion is one of the key parameters controlling progress various processes occurring in porous materials. For fluids confined to mesoporous solids, diffusion, addition complex structure these materials, found be further diversified by their rich phase behaviour, giving rise a strong coupling between state and internal dynamics. By applying NMR as non-perturbing experimental technique, results systematic studies fluid microscopic macroscopic dynamics solids are reviewed. In particular, correlations diffusive details gas–liquid solid–liquid coexistences explored. Selected examples concerning dynamic behaviour accompanying other types transitions presented.
