Studies on Emulsification. II.

Phase Inversion Emulsification

Phase inversion refers to a phenomenon that occurs when agitated oil in water emulsion, reverts to a water in oil and vice versa. Emulsification via phase inversion is widely used in fabrication of cosmetic products, pharmaceutical products (e.g., vesicles for drug delivery), foodstuff and detergents. Emulsification process is strongly affected by preparation method; very different droplet size...

Dynamics of spontaneous emulsification

We present a model for spontaneous emulsification resulting from a transiently negative interfacial tension between water and oil regions, which may be achieved under conditions of strong adsorption of surfactant molecules to the interface. While our approach builds on a linear stability analysis, it addresses the essential non-linear coupling of surface growth to the diffusion flux of surfacta...

Studies on Echinococcosis : Ii. Echinococcosis in Japan

Further Studies on Bacterial Hypersusceptibility. Ii

When filtered alkaline extracts of pulverized bacteria of several varieties are precipitated with acid in the cold, boiled with acid, and all materials thrown down by these procedures removed, there remains a small amount of an alcohol-precipitable material which no longer gives any of the ordinary chemical reactions for proteins, such as the biuret, Hopkins-Cole, Millon, and sulfosalicylic aci...

Studies on erythropoietic action of angiotensin II.

S INCE THE ESTABLISHMENT of a concept that erythropoiesis is controlled by erythropoietin (Ep), search for the production site of Ep has been one of the major projects. From the results obtained from both clinical and experimental research carried out so far, the kidney has been regarded as the organ playing an important role in the production of Ep. However, the mechanism of the production is ...
