Optimizing organoclay stabilized Pickering emulsions
Journal of Colloid and Interface Science, 2011Oil-in-water emulsions were prepared using montmorillonite clay platelets, pre-treated with quaternary amine surfactants. In previous work, cetyl trimethylammonium bromide (CTAB) has been used. In this study, two more hydrophilic quaternary amine surfactants, Berol R648 and Ethoquad C/12, were used and formed Pickering emulsions, which were more stable

Colloid Surfactants for Emulsion Stabilization
Advanced Materials, 2008Similar concepts of packing should, inprinciple,alsobeapplicabletocolloidalparticles.Ifso,itmightbe possible to control the emulsion drop size and shape withthe same strategy as used for molecular surfactants, providingconsiderable flexibility control to the emulsion.

Emulsion Stability and Stabilization
2004On storage (aging), unexposed and undeveloped silver halide materials tend to change their sensitometric characteristics, especially speed (S), gradient (g), and minimum, and minimum density (Dmin). Usually, speed and gradient decrease, whereas fog increases.

Emulsions stabilized with solid nanoparticles: Pickering emulsions
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2013Pickering emulsions are attractive formulations because they are simple and bear strong similarities with the well-known surfactant-based emulsions. Pickering emulsions have been largely ignored since their early disclosure in 1907 and arouse a renewed interest quite recently.

Conditions for Equilibrium Solid-Stabilized Emulsions
The Journal of Physical Chemistry B, 2010Particular types of solid-stabilized emulsions can be thermodynamically stable as evidenced by their spontaneous formation and monodisperse droplet size, which only depends on system parameters. Here, we investigate the generality of these equilibrium solid-stabilized emulsions with respect to the basic constituents: aqueous phase with ions, oil, and ...
