Dispersion of TiN in aqueous media

Journal of Colloid and Interface Science, 2005
The dispersion of TiN powders in aqueous media was studied through XPS, zeta potential, adsorption, sedimentation, and rheology measurements. XPS showed that there are TiO2, TiN, and TiOxNy sites on the TiN particle surface. In the absence of dispersant, the isoelectric point (pH(IEP)) of the TiN particles was at pH 2.2. Based on the surface properties

Non-Aqueous Dispersions

Journal of Elastoplastics, 1971
Polyvinyl chloride is the most common polymer for organosols Sec ond to PVC are the acrylics Polymer particles of colloidal size required for microgel formation can be formed by standard emulsion polymerization techniques. Effect of the solvent on film formation and the coating is important.

Spontaneous vesiculation of aqueous lipid dispersions

Biochemistry, 1986
The swelling properties of lipid mixtures consisting of phosphatidylcholine and a charged single-chain detergent have been studied. The work presented here is confined to lipid mixtures forming smectic lamellar phases in H2O. These mixtures exhibit continuous swelling with increasing water content, provided the surface charge density exceeds a ...

Rheology of aqueous carbon black dispersions

Journal of Colloid and Interface Science, 2004
The interaction of carbon black with an acrylic resin has been investigated by rheology. Two carbon blacks, with similar particle size and surface characteristics but quite different particle morphologies, have been examined. These are somewhat arbitrarily denoted as "spherical" and "fractal" as shown by small-angle neutron scattering (SANS) and ...

Aqueous polyurethane dispersions

Colloid & Polymer Science, 1996
This review describes basic chemistry, preparation process, and physical properties of aqueous polyurethane disperisons and the derived films, along with the methods of post treatment to modify the properties. Basic way to render a polyurethane water dispersible without external emulsifier has been described.

Dioxygen solubility in aqueous phosphatidylcholine dispersions

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1991
The solubility of molecular oxygen, or dioxygen, in low weight percent (1.5%) sonicated dimyristoylphosphatidylcholine (DMPC) aqueous dispersions saturated with air has been measured as a function of temperature between 10 degrees C and 40 degrees C.
