Structures and Permselectivities of Phase Separated Membranes.

Diatom structures templated by phase-separated fluids.

An experimentally motivated model is proposed for the formation of fluid-phase templates corresponding to the porous silica skeletons of diatoms, single-cell organisms found in marine and freshwater environments. It is shown that phase-separation processes on a planar surface may give rise to a quasi-static mold that could direct the deposition of condensing silica to form complex arrays of por...

SEM, TEM, and AFM Analyses of Phase-Separated Polymer Blend Membranes for Gas Separations

Polymer blends are proving to be important in emerging technologies including as gas separation membranes [1]. The blending of existing polymers offers the distinct advantage of being able to develop new materials with potentially synergistic properties not attainable with the individual polymer components and without the need to synthesize new macromolecules [2]. We recently developed phasesep...

Thermal Stability of Phase-Separated Domains in Multicomponent Lipid Membranes with Local Anesthetics

The functional mechanisms of local anesthetics (LAs) have not yet been fully explained, despite their importance in modern medicine. Recently, an indirect interaction between channel proteins and LAs was proposed as follows: LAs alter the physical properties of lipid membranes, thus affecting the channel proteins. To examine this hypothesis, we investigated changes in thermal stability in lipid...
