Spinodal Decomposition in Liquid-Quenched Co-Cu Alloys

Spinodal decomposition in liquid crystalline materials

The theory of phase separation m a liquid crystal by spinodal decompoSit1on is developed The time evolution of two coupled parameters, the volume concentration (or mole fraction), and the orientational order parameter is calculated The conditions for penodic fluctuations are gJven and the structure factor for spinodal decomposition is studied

Spinodal phase separation in liquid films with quenched disorder.

We study spinodal phase separation in unstable thin liquid films on chemically disordered substrates via simulations of the thin-film equation. The disorder is characterized by immobile patches of varying size and Hamaker constant. The effect of disorder is pronounced in the early stages (amplification of fluctuations), remains during the intermediate stages and vanishes in the late stages (dom...

Colloid-in-liquid crystal gels formed via spinodal decomposition.

We report that colloid-in-liquid crystal (CLC) gels can be formed via a two-step process that involves spinodal decomposition of a dispersion of colloidal particles in an isotropic phase of mesogens followed by nucleation of nematic domains within the colloidal network defined by the spinodal process. This pathway contrasts to previously reported routes leading to the formation of CLC gels, whi...

Liquid-liquid phase separation in concentrated solutions of non-crystallizable polymers by spinodal decomposition

In the past, investigations of phase separation in concentrated polymer solutions centered first of all on the crystallization kinetics (1) and morphology (2) of polymer crystals growing from solutions and, secondly, on the equilibrium thermodynamic properties of liquid-liquid phase separation phenomena (3). Papkov and Yefimova (4) have recently given a classification of different types of phas...
