Description
Summary:A model water-filled porous medium is investigated using NMR techniques, and the results of these measurements are interpreted theoretically. A rigorous theoretical description of the near-surface layer, qualitatively introduced when interpreting the NMR data for porous materials, is formulated. Our results indicate that the thickness of the near-surface layer exceeds that quoted in the literature by several orders of magnitude. This result allows to obtain valuable information about the processes at the liquid-solid interface.
