| Research Abstract |
We developed a NMR system equipped with a high-pressure cell for measuring water properties confined in nanoporous materials such as silica beads and bentonite clays. The NMR relaxation times and diffusion coefficients of the confined water molecules were examined. From these results, we found that the molecular motions of the confined water were inhibited compared with bulk water, and that their motions depended strongly on the pressures. Moreover, a novel NMR probe, which can examine the effects on ions for the confined water, was constructed.
