As a result of the convective flow of solutes through porous membranes, membrane chromatography has a higher capture efficiency and a higher productivity than column chromatography and shows most promising industrial applications for the recovery, isolation, and purification of proteins and enzymes. This paper presents a comprehensive review of the methods for preparation of adsorptive membrane...

After the pioneering works by Canham and Helfrich in 70's, increasing researchers have investigated theoretically and experimentally in depth the shape deformation of a homogeneous fluid membrane vesicle by the change of their environments such as temperature, pH and osmotic pressure. Recently, much attention has been paid to two component vesicles because such systems are considered to be idea...

Molecular dynamics (MD) simulations are used to study the interaction of an anionic palmitoyl-oleoyl-phosphatidylglycerol (POPG) bilayer with the cationic antimicrobial peptide bovine lactoferricin (LFCinB) in a 100 mM NaCl solution at 310 K. The interaction of LFCinB with a POPG bilayer is employed as a model system for studying the details of membrane adsorption selectivity of cationic antimi...

• Gas and vapour transport in Poly(vinyl alcohol)/[EMIM][DCA] blend membranes are studied. CO 2 is highly pressure-dependent at low pressure, suggesting facilitated to play a role. Permeability, solubility diffusivity follow-Arrhenius-type temperature dependence. Humidity the gas feed improves /CH 4 mixed separation performance. Membrane technology rapidly emerging as an alternative traditional...

The conductivity of fuel cell membranes as well as their mechanical properties at the nanometer scale were characterized using advanced tapping mode atomic force microscopy (AFM) techniques. AFM produces high-resolution images under continuous current flow of the conductive structure at the membrane surface and provides some insight into the bulk conducting network in Nafion membranes. The corr...

Graphene and other two-dimensional materials offer a new approach to controlling mass transport at the nanoscale. These materials can sustain nanoscale pores in their rigid lattices and due to their minimum possible material thickness, high mechanical strength and chemical robustness, they could be used to address persistent challenges in membrane separations. Here we discuss theoretical and ex...
