“…It appears that in the distance regime 6 nm < h < 20 nm a deviation to higher repulsive effects is manifest. An analogous behaviour is reported by Israelachvili and Adams [5] and Pashley [7,8], who point out that in this regime the repulsion data obviously lie between constant surface potential and constant surface charge conditions. The latter corresponds to higher electrical repulsive effects at closer plate separations.…”

“…The deficiency of the DLVO theory concerns the drastic rise of the disjoining force for h < 6 nm which is likewise quoted by Israelachvili and Adams [6] and Pashley [7,8]. These findings support the concept of a muhimolecular hydration layer on the solid surface.…”

“…Particles with high values maintain larger distances than those between particles with lower surface-charge densities. mental measurements of such properties as osmotic pressure (Barclay et al, 1972), disjoining pressure (Peschel and Belouschek, 1977), and freezing point depression of water in clay pastes (Helmy et al, 1979). The distances between particles may be obtained from X-ray diffraction methods (Norrish, 1954), and the average water film thickness, i.e., the average distance between the particles, is in turn available from water content measurements if the specific surface area of the sample is also known.…”
