    Notes: Abstract The microemulsions formed in the 4-component system water-potassium oleate-hexanol-dodecane have been investigated by time-average light scattering and small angle neutron scattering. A constant volume fraction ratio water: potassium oleate of 1.44 was used and at this constant composition, which gave a pseudo 3-component system, a wide region of the microemulsion domain was examined. In order to interpret the scattering data at finite volume fractions of the dispersed phase, water, allowance had to be made for interactions between the water-in-oil microemulsion droplets. This was carried out using a hard sphere model for the interaction. It is shown that using this model self-consistent results are obtained by light scattering and neutron scattering and an estimate can be made of the size of the particles in concentrated colloidal dispersions.

    Small angle neutron scattering studies on non-aqueous dispersions of calcium carbonate (1984)
    Springer
    Colloid & polymer science 262 (1984), S. 648-656

    Notes: Abstract Colloidal dispersions of calcium carbonate in toluene, with the particles stabilised by an alkyl aryl sulphonic acid, have been examined by small angle neutron scattering. On the basis of the assumption that the adsorbed layer of stabilising surface active agent formed a concentric shell around a spherical calcium carbonate core particle, a method was developed to determine both the radius of the core particle and the thickness of the adsorbed layer. For the two series of particles examined the calcium carbonate core particles were found to have radii of 22 and 67 å respectively and in both cases the adsorbed layer thickness was found to be 19.0±1 å. The method provides a means of obtaining adsorbed layer thicknesses under conditions where particle and layer cannot be separated.

    Notes: Abstract Small angle neutron scattering studies have been made on solutions of dodecylhexaoxyethylene glycol in D2O above the critical micelle concentration and as a function of temperature. It was possible to fit the experimental data at low values of scattering vector using a cylindrical model for the micelle shape.

    Small angle and quasi-elastic neutron scattering studies on polymethylmethacrylate latices in nonpolar media (1983)
    Springer
    Colloid & polymer science 261 (1983), S. 555-564

    Notes: Abstract Poly(methylmethacrylate) particles stabilised by poly(12-hydroxystearic acid) in a hydrocarbon medium provide, as a polymer latex, a useful system for investigating the properties of a sterically stabilised concentrated dispersion. In the present work these latices were investigated by small angle coherent neutron scattering and by quasielastic incoherent scattering. The former technique was used to probe the dimensions of the surface layer of poly(12-hydroxystearic acid) and to determine the diameter of the core particle of poly(methylmethacrylate) using dilute dispersions. In concentrated dispersions it was used to determine the structure factor. The latter was compared with that expected for an interacting system of hard spheres and reasonable agreement obtained. The quasielastic technique was used to probe the translational diffusion of the poly(12-hydroxystearic acid) molecules on the surface and the diffusion of the total particles in the concentrated systems.
