Evaluation of stability ratio in oil-in-water emulsions

In this experimental investigation of rapid Brownian coagulation in dilute oil-in-water emulsions, the absence of deformation influence on droplet interaction and drainage is established. The result is in agreement with the theory of Brownian coagulation in miniemulsions proposed by the Borwankar-Ivanov group. As a first approximation the applicability of Smoluchowski theory to rapid coagulation in emulsions is established. Observing the weak influence of droplet deformation on rapid coagulation and taking into account Borwankar-Ivanov theory that the transition to charged droplets and lower electrolyte concentrations decreases the droplet deformation, we conclude that both slow coagulation and the reversible one cannot be influenced by droplet deformation in miniemulsions. A droplet surface is homogenous in contrast to solid particle surfaces. Thus emulsions can be used as a

Surface conductivity of counter ions on protein-adsorbed lipid liposomes

Ionic surface diffusitivity is important parameter for the electrostatic interaction between colloid particles and hence its measurement is a new important factor for the surface characterization of colloid particles. If the adsorbed ion mobility is small the approximation of the interaction at constant charge can be valid,but in opposite case the charge regulation occurs during their interaction. The large surface diffusitivities of polyvalent ions adsorbed on negatively charged liposomes are found combining measurements of conductivity and electrophoresis. At a rather low surface charge and high adsorbability of polyvalent cations, the diffuse-layer charge can be very small in comparison with the Stern-layer charge, which can predominate in surface conductivity and provide information about the diffusitivity of adsorbed ions if it is not small. An efficient and simple method for the discrimination between small and large surface diffusitivities of adsorbed ions based on the determination of bot...
