The upper bound of thin-film composite (TFC) polyamide membranes for desalination

Journal of Membrane Science, 2019
Membrane separation properties are constrained by a tradeoff relationship between permeability and selectivity. This tradeoff relationship has been well established for gas separation membranes in the form of the Robeson's upper bound.

Membrane-membrane interactions: parallel membranes or patterned discrete contacts

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1990
Theoretical 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 ...

Mechanics of membrane–membrane adhesion

Mathematics and Mechanics of Solids, 2011
Curvature 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.

Membranous Laryngotracheobronchitis

Pediatrics, 1982
The etiology, clinical presentation, and therapeutic strategies associated with membranous laryngotracheobronchitis are discussed. A case is presented in which a lateral neck radiograph gave the preliminary impression of a tracheal foreign body.

Zwitterionic Nanohydrogel Grafted PVDF Membranes with Comprehensive Antifouling Property and Superior Cycle Stability for Oil‐in‐Water Emulsion Separation

Advanced Functional Materials, 2018
Fouling caused by oil and other pollutants is one of the most serious challenges for membranes used for oil/water separation. Aiming at improving the comprehensive antifouling property of membranes and thus achieving long‐term cyclic stability, it is ...

From membranes to membrane machines

2008
On 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

2014
The 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,
