Liquid-liquid immiscibility in lipid monolayers.
Some binary lipid mixtures form coexisting liquid phases when spread at the air/water interface. This work describes the pressure-composition phase diagrams of binary mixtures of four unsaturated phosphatidylcholines with dihydrocholesterol. These four binary mixtures have critical compositions of approximately fifty mole percent, and average critical exponents of 0.25 +/- 0.07. The data can al...

متن کاملNo liquid immiscibility in the system MgSiO3-SiO2 at 5.0 GPa
A b s t r a c t L i q u i d u s phase relationships in the system MgSiO3-SiO2 at 5.0 GPa have been determined using a multianvil apparatus. Compared to phase relationships at 1 atm, the MgSiO3-SiO2 phase diagram at 5.0 GPa is significantly different in two respects. First, the composition of the eutectic between MgSiO3 and SiO2 moves from 65.0 wt% SiO2 at 1 atm/1547°C (protoenstatite-cristobali...
متن کاملLiquid-Liquid Immiscibility in Pure Fluids: Polyamorphism in Simulations of a Network-Forming Fluid.
We report Monte Carlo simulations that show both vapor-liquid and closed-loop liquid-liquid equilibrium in a pure substance, for a model fluid that forms orientation-dependent intermolecular bonds. This is the first time that direct evidence of liquid-liquid immiscibility in a pure fluid has been found using exact methods. Because the model is formulated in terms of a tetrahedrally coordinated ...
