Temperature-induced liquid crystal microdroplet formation in a partially miscible liquid mixture

Dissolution of a liquid microdroplet in a nonideal liquid-liquid mixture far from thermodynamic equilibrium.

A droplet placed in a liquid-liquid solution is expected to grow, or shrink, in time as approximately t;{1/2}. In this Letter, we report experimental evidence that when the composition in the interface is far from thermodynamic equilibrium due to the nonideality of the mixture, a droplet shrinks as approximately t. This scaling is due to the coupling between mass and momentum transfer known as ...

Molecular-dynamics simulation of the effect of ions on a liquid-liquid interface for a partially miscible mixture.

Molecular-dynamics simulations were performed to model the effect of added salt ions on the liquid-liquid interface in a partially miscible system. Simulations of the interface between saturated phases of a model 1-hexanol+water system show a bilayer structure of 1-hexanol molecules at the interface with -OH heads of the first layer directed into the water phase and the opposite orientation for...

Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

A density functional study of liquid–liquid interfaces in partially miscible systems

Liquid–liquid interfaces and nucleation in partially miscible Lennard–Jones ~LJ! mixtures are considered using density functional theory. We present phase diagrams, interfacial liquid–vapor and liquid–liquid profiles, and gas–liquid as well as liquid–liquid surface tensions for two types of mixtures having different mixing rules for the LJ energy parameter. A simple local density approximation ...
