Spinodal decomposition in two-component smectics
نویسندگان
چکیده
-A two-component smectic undergoing a demixing tran~ition to two coexisting smectic pha~es exhibits a novel spinodal pattern as observed by light ~cattering and optical microscopy. We show that this ~pinodal, characterized by a prescribed angle between the mo~t intense wavevectors and the layer normal, is the result of the instability of the baroclinic mode of two-cojnponent smectic hydrodynamics.

Formation of Poly(vinylidene fluoride) Nanofibers Part II: the elaboration of incompatibility in the electrospinning of its solutions
Poly(vinylidene fluoride) (PVDF) fibers with two molecular weights were prepared via electrospinning process. In this process, the concentration of spinning depended drastically on the gelation process. Also, it was experimentally smaller than obtained concentration in the solution entanglement number approach (SENA). Proof of this incompatibility was explained by the properties of PVDF a...

متن کاملSpinodal decomposition of a binary magnetic fluid confined to a surface.
In our previous work [J. Chem. Phys. 136, 024502 (2012)], we reported a demixing phase transition of a quasi-two-dimensional, binary Heisenberg fluid mixture driven by the ferromagnetic interactions of the magnetic species. Here, we present a theoretical study for the time-dependent coarsening occurring within the two-phase region in the density-concentration plane, also known as spinodal decom...
