FOAM AND EMULSION FILMS STABILIZED WITH MICROTALC PARTICLES

BslA-stabilized emulsion droplets with designed microstructure

Emulsions are a central component of many modern formulations in food, pharmaceuticals, agrichemicals and personal care products. The droplets in these formulations are limited to being spherical as a consequence of the interfacial tension between the dispersed phase and continuous phase. The ability to control emulsion droplet morphology and stabilize non-spherical droplets would enable the mo...

Unique properties of bubbles and foam films stabilized by HFBII hydrophobin.

The HFBII hydrophobin is an amphiphilic protein that can irreversibly adsorb at the air/water interface. The formed protein monolayers can reach a state of two-dimensional elastic solid that exhibits a high mechanical strength as compared to adsorption layers of typical amphiphilic proteins. Bubbles formed in HFBII solutions preserve the nonspherical shape they had at the moment of solidificati...

Foam films obtained with ionic liquid.

Synthesis of polystyrene-silica composite particles via one-step nanoparticle-stabilized emulsion polymerization.

Polystyrene-silica core-shell composite particles are prepared by one-step emulsion polymerization with a nonionic initiator VA-086, solely stabilized by silica nanoparticles. The silica nanoparticles are successfully incorporated as the shell, likely due to the fact that the nanoparticles are thermodynamically favorable to adsorb and remain at the liquid-liquid interfaces during the emulsion p...

Hydrophobic Forces in the Foam Films Stabilized by Sodium Dodecyl Sulfate: Efect of Electrolyte

Further studies of the hydrophobic force in foam films were carried out, including the effect of added inorganic electrolyte. We used a thin film balance of Scheludko-Exerowa type to obtain the disjoining pressure isotherms of the foam films stabilized by 10-4 M sodium dodecyl sulfate in varying concentrations of sodium chloride. The results were compared with the disjoining pressure isotherms ...
