To predict double-emulsion formation in a capillary microfluidic device, a ternary diffuse-interface model is presented. The formation of double emulsions involves complex interfacial phenomena of a three-phase fluid system, where each component can have different physical properties. We use the Navier-Stokes/Cahn-Hilliard model for a general ternary system, where the hydrodynamics is coupled w...

Non-alcoholic fatty liver disease (NAFLD) is emerging as a common medical problem. Nonalcoholic steatohepatitis (NASH) is the critical turning point at which NAFLD progresses to more advanced stages such as hepatic fibrosis, cirrhosis and even hepatocellular carcinoma. However, the study of the pathogenic or therapeutic factors involved in NASH has been hampered by the absence of a suitable exp...

there are numerous problems for using essential oil due to its low solubility in water, high vapor pressure and chemical and physical instability. use of nano-emulsions is a good idea for decreasing side effect of the essential oils and enhance their efficiency as well as delivery to hot spot. in addition, nano-emulsion system make smaller size particles and increase stability and shelf-life of...

The chemicals used for the NPs synthesis are TetraEthylOrthoSilicate (TEOS), l-Arginine, chloride acid 0.1M and ethanol. They were supplied by Aldrich and used as received. High-purity deionized water (18.2 M.cm) was produced using Millipore Milli-Q Gradient system. The synthesis follows the same protocol as in our previous work [1]. It is performed in a 2000 ml reactor thermostated with hot wa...

The angular distributions of scattering of 10 and 14Mev neutrons by deuterons have been investigated using photographic emulsions. 1540 deuteron recoils entering the emulsion from a thin target of heavy wax placed in contact with its surface were measured. The results are shown to be in good agreement with the recent theoretical curves of Buckingham, Hubbard and 1VIassey. The errors to which th...

The evolution of double-emulsion droplets is of great importance for the application of microdroplets and microparticles. We study the driving force of the dewetting process, the equilibrium configuration and the dewetting time of double-emulsion droplets. Through energy analysis, we find that the equilibrium configuration of a partial engulfed droplet depends on a dimensionless interfacial ten...

Acknowledgements We would like to express our gratitude to everyone who advised and assisted with our research throughout our time at ENSIC. We sincerely appreciate their time and efforts. Abstract The goal of this project was to investigate the properties of alginate stabilized emulsions and their potential role for drug delivery. The polymer acts as a barrier between phases in oil-in-water em...

Characterization of rheological behavior of alkali-surfactant-polymer (ASP) solution and oil emulsion is difficult, due to the complex chemical components and various physiochemical reactions with oil during chemical flooding. Through rheological experiments of ASP and crude oil emulsion, this paper presents the studies on influencing factors of rheological behavior, including interfacial tensi...
