Spinodal decomposition in microemulsions

Parallel Spinodal Decomposition

Spinodal decomposition encompasses the ordering dynamics of thermodynamically unstable phases. An example of spinodal decomposition is the separation of the metals in a binary alloy. Because physicists have been unable to develop a fully coherent, consistent , and calculable theory on spinodal decomposition, computational studies have served as valuable sources of information. However, since th...

Quantum spinodal decomposition.

We study the process of spinodal decomposition in a scalar quantum field theory that is quenched from an equilibrium disordered initial state at Ti > Tf to a final state at Tf ≈ 0. The process of formation and growth of correlated domains is studied in a Hartree approximation. We find an approximate scaling law for the size of the domains ξD(t) ≈ √ tξ0 at long times for weakly coupled theories,...

Isotropic-nematic spinodal decomposition kinetics.

The initial stage of isotropic-nematic spinodal demixing kinetics of suspensions of very long and thin, stiff, repulsive rods is analyzed on the basis of the N-particle Smoluchowski equation. Equations of motion for the reduced probability density function of the position and orientation of a rod are expanded up to second order in spatial gradients and leading order in orientational order param...

NONLINEAR KINETICS OF SPINODAL DECOMPOSITION, AND DISSOLUTION OF INHOMOGENElTIES FORMED BY SPINODAL DECOMPOSITION IN POLYMER BLENDS

Nonlinear kinetics of both spinodal decomposition at early stages, and the dissolution of homogeneities formed during spinodal decomposition,is studied. Variation of the scattering intensity during a complete cycle consisting of a step temperature change from T i in the one-phase. region to T2 in the two-phase region, a period of spinodal decomposition followed by a temperature drop from T2 bac...
