Plasma membranes of cells are asymmetric in both lipid and protein composition. The mechanism by which proteins on both sides of the membrane colocalize during signaling events is unknown but may be due to the induction of inner leaflet domains by the outer leaflet. Here we show that liquid domains form in asymmetric Montal-Mueller planar bilayers in which one leaflet's composition would phase-...

Biocatalytic membrane reactors (BMR) combining reaction and separation within the same unit have many advantages over conventional reactor designs. Ceramic membranes are an attractive alternative to polymeric membranes in membrane biotechnology due to their high chemical, thermal and mechanical resistance. Another important use is their potential application in a biphasic membrane system, where...

The phase separation behavior of bisphenol-A-polycarbonate (PC), dissolved in N-methyl-2-pyrrolidone and dichloromethane solvents in coagulant water, was studied by the cloud point method. The respective cloud point data were determined by titration against water at room temperature and the characteristic binodal curves for the ternary systems were plotted. Further, the physical properties such...

This paper describes the preparation of asymmetric cell-sized lipid vesicles from a planar lipid bilayer by using pulsed jet flow. First, the cell-sized vesicles (diameter of 5 μm in over 1 day) were stably formed using an improved double-well device wherein a separator with a small hole was mounted between the wells (Fig.1). Moreover, asymmetric vesicles of phosphatidylserine lipids were succe...

the asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. the rigid disk is assumed to be in frictionless contact with the elastic half-space. by virtue of appropriate green's functions, the mixed boundary value problem is written as a dual integral equation. employing further mathematica...
