D was found to be in the range 0.17·10 6 to 2.3·10 6 cm 2 /s and could be expressed by an equation of the form D 1 ∝ D ∞ 1 + α· l c 2 where D ∞ is the self-diffusion coefficient of bulk water ( l c = ∞) and α = (2.68 ± 0.14)·10 5 s. The low ...
Self-diffusion of water in ionic and nonionic microemulsionsThe self-diffusion coefficient of water in four microemulsion systems was measured using an NMR-pulsed field gradient technique. The systems studied were two containing ionic surfactants and two with nonionic surfactants. The dielectric relaxation...

The true values of the diffusion coefficients were calculated from the values of D(obs) in the plateau regions by applying a correction for the fraction of water protons present, obtained from the equilibrium water contents of the gels. The true self-diffusion coefficient for water in polyHEMA ...
