Asymmetric membrane structures as a result of phase separation phenomena

Phase Separation Phenomena During the Formation of Asymmetric Membranes

The formation of membranes from two systems has been studied. In the system polyurethanedimethylformamide-water, the mechanism for the formation of the sponge-like structure proves to be a liquid-liquid phase separation with nucleation and growth of the diluted phase. This mechanism has been confirmed for the system modified polystyrene-polyisoprene-polystyrene/ o-dichlorobenzene/(methanol-wate...

Phase-separation transitions in asymmetric lipid bilayers

Morphological transitions of phase separation associated with the asymmetry of lipid composition were investigated using micrometer-sized vesicles of lipid bilayers made from a lipid mixture. The complete macro-phase-separated morphology undergoes a transition to a micro-phase-separation-like morphology via a lorate morphology as a metastable state. The transition leads to the emergence of mono...

Phase transition phenomena in random discrete structures

A random discrete structure is a combinatorial object, which emerges as a result of a series of random experiments; equivalently, it can be viewed as a probability space whose elements are combinatorial structures as graphs, hypergraphs, permutations etc. In many of random discrete structures a small change of parameters of the model can greatly affect its (typical) behaviour. One of the semina...
