Novel Membranes and Membrane Materials
2018In this chapter, the state-of-the-art membrane materials used for forward osmosis (FO) and pressure-retarded osmosis (PRO) processes are presented. Conventional polymeric membranes, such as cellulose triacetate and thin-film composite membranes, are briefly introduced.

The disk membrane as model for an excitable membrane
Neurochemistry International, 1980Excitable membranes appear to be biochemically characterized by the presence of a highly specific receptor protein, which undergoes conformational changes upon stimulation and returns to its original conformation for renewed excitability. Our present knowledge of the disk membrane and its receptor protein rhodopsin is reviewed in the light of this ...

Mechanics of membrane–membrane adhesion
Mathematics and Mechanics of Solids, 2011Curvature elasticity is used to derive the equilibrium conditions that govern the mechanics of membrane–membrane adhesion. These include the Euler–Lagrange equations and the interface conditions which are derived here for the most general class of strain energies permissible for fluid surfaces.

Advanced Drug Delivery Reviews, 1999
Although catalyzed by different proteins, the energy barriers for lipid bilayer fusion in exocytosis, viral fusion, and trafficking seem to be the same as those for the fusion of protein-free phospholipid membranes. To minimize this energy, fusion will proceed through a minimal number of lipid molecules, probably localized in bent non-bilayer ...

From membranes to membrane machines
2008On the micrometer scale, the behavior of membranes and vesicles can be understood, to a large extent, in terms of a few parameters. Two of these parameters, which are crucial for the membrane morphology, are the vesicle volume and the preferred or ‘spontaneous’ curvature of the membrane.1 The volume is primarily determined by the osmotic conditions, i ...

Lipid Membranes for Membrane Proteins
2014The molecular dynamics (MD) simulation of membrane proteins requires the setup of an accurate representation of lipid bilayers. This chapter describes the setup of a lipid bilayer system from scratch using generally available tools, starting with a definition of the lipid molecule POPE, generation of a lipid bilayer, energy minimization, MD simulation,

Membrane-membrane interactions: parallel membranes or patterned discrete contacts
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1990Theoretical and experimental studies of thin liquid films show that, under certain conditions, the film thickness can undergo a sudden transition which gives a stable narrower film or ends in film rupture at spatially periodic points. Theoretical analysis have also indicated that similar transitions might arise in the thin aqueous layer separating ...

MEMBRANES FOR IMPROVED MEMBRANE DISTILLATION AND MEMBRANE CRYSTALLIZATION
2020Symmetric PVDF porous membranes with Graphene flakes have been prepared by phase inversion technique and used to equip membrane distillation devices. Very high water flux and total salt rejection have been obtained with long-term stability and resistance to fouling.
