Liquid-liquid phase separation (LLPS) phenomenon are widely recognized to be of vital importance for physics, materials science, and biology. It is highly desired develop powerful tools study the LLPS behavior related physical mechanisms. For this purpose, a phase-field method was developed here which combines Cahn-Hilliard diffusion equation Navier-Stokes equation. The morphological evolution ...

The authors solved a microscopic model that describes mixtures of a saturated phospholipid, an unsaturated phospholipid, and cholesterol. The method employed was the self-consistent field approximation. The model was capable of producing several classes of phase diagram, but only one of them showed a liquid-liquid coexistence region. The phospholipids in the cholesterol-rich liquid are more ord...

Xanthan gum is a high molecular weight substance with potential in improving emulsions properties. The formulation composition was selected on Tween 80 ternary phase diagram and was modified by the addition of xanthan gum at different concentrations (0.0% – 1.0%). The main objective of this study was to determine the effect of xanthan gum on physicochemical and rheological properties of rice br...

We have characterized the phase behavior of mixtures of the cationic surfactant cetyltrimethylammonium bromide (CTAB) and the organic salt 3-sodium-2-hydroxy naphthoate (SHN) over a wide range of surfactant concentrations using polarizing optical microscopy and X-ray diffraction. A variety of liquid crystalline phases, such as hexagonal, lamellar with and without curvature defects, and nematic,...

The interaction of methotrexate (MTX) with beta-cyclodextrin (β-CD) in the presence of triethanolamine (TEA) was investigated with the aim to elucidate the mechanism whereby self-assembly cyclodextrin systems work in association with this third component. Solubility diagram studies showed synergic increment of the MTX solubility to be about thirty-fold. Experiments using 2D ROESY and molecular ...

The Bi-Sn-Zn system has not been studied, till present, in all its extension; at least it was not done a complete optimization and assessment of the phase diagram. D. Malakhov et al. [1], as well as N. Moelans et al. [2], have only optimized and assessed the liquid phase of the ternary system due to the lack of data for the thermodynamic properties of terminal solid solutions as well as on thei...
