Phase Separation of Viscous Ternary Liquid Mixtures
In this work we study the demixing of ternary liquid mixtures. Our theoretical model follows the standard diffuse interface model, where convection and diffusion are coupled via a body force, expressing the tendency of the mixture to minimize its free energy. This driving force induces a material flux which, in most cases, is much larger than that due to pure molecular diffusion. Here we model ...
متن کاملTailoring of high-order multiple emulsions by the liquid-liquid phase separation of ternary mixtures.
Multiple emulsions with an "onion" topology are useful vehicles for drug delivery, biochemical assays, and templating materials. They can be assembled by ternary liquid phase separation by microfluidics, but the control over their design is limited because the mechanism for their creation is unknown. Herein we show that phase separation occurs through self-similar cycles of mass transfer, spino...
متن کاملPhase-separation transition in liquid mixtures near curved charged objects.
We study the thermodynamic behavior of nonpolar liquid mixtures in the vicinity of curved charged objects, such as electrodes or charged colloids. There is a critical value of charge (or potential), above which a phase-separation transition occurs, and the interface between high- and low-dielectric constant components becomes sharp. Analytical and numerical composition profiles are given, and t...
متن کاملSeparation of liquid phases in giant vesicles of ternary mixtures of phospholipids and cholesterol.
We use fluorescence microscopy to directly observe liquid phases in giant unilamellar vesicles. We find that a long list of ternary mixtures of high melting temperature (saturated) lipids, low melting temperature (usually unsaturated) lipids, and cholesterol produce liquid domains. For one model mixture in particular, DPPC/DOPC/Chol, we have mapped phase boundaries for the full ternary system. ...
متن کاملMechanical properties of ternary lipid membranes near a liquid-liquid phase separation boundary.
We study the mechanical properties of ternary lipid bilayers assembled in giant vesicles, formed from a saturated and an unsaturated phosphocholine (in equal proportions) and cholesterol. As a function of temperature, these systems can undergo in-plane phase separation. Using image analysis we identify the vesicle contour, and quantify the vesicle shape and the amplitude of membrane thermal flu...
