| Outline of Final Research Achievements |
Water confined in a nanometer cavity shows unusual behavior that cannot occur in the bulk. Here we have studied the structure and dynamics of water confined in nanocavities of nanocarbon materials by several experimental methods, including nuclear magnetic resonance measurements and molecular dynamics simulations. As for water adsorbed on zeolite-templated carbons, we have observed that the rotational correlation time of nanoconfined water molecules become longer by applying pressure. Furthermore, we have revealed wet-dry transition of water-adsorbed single-walled carbon nanotubes (SWCNTs) and liquid-solid phase transition of confined water inside SWCNTs.
