The latest developments and applications of hollow fiber membrane contactors (HFMCs) were discussed in this recent published book. Membrane contactor provides gas–liquid or liquid–liquid contact without dispersion one phase another, which gives a higher mass transfer coefficient compared to the conventional contactors. Using microporous hydrophobic hydrophilic membrane, fluids is immobilized po...

Nowadays, membrane processes are widely used for high purity Nitrogen production. Separation of air by membranes is a flexible process in which the investment and operational costs are lower than for example adsorption or cryogenic processes. Such processes are based on relative permeability of air components which are transported by the pressure difference between two sides of the membrane. M...

A hybrid-fiber nanogenerator comprising a ZnO nanowire array, PVDF polymer and two electrodes is presented. Depending on the bending or spreading action of the human arm, at an angle of ∼90°, the hybrid fiber reaches electrical outputs of ∼0.1 V and ∼10 nA cm(-2) . The unique structure of the hybrid fiber may inspire future research in wearable energy-harvesting technology.

High safety and rate capability of lithium-ion batteries (LIBs) remain challenging. In this study, sandwich-structured poly(vinylidene fluoride)/poly(vinylidene fluoride-co-hexafluoropropylene)/poly(vinylidene fluoride) (PVDF/PVDF-HFP/PVDF) membranes with thermal shut-down function were successfully prepared through electrospinning. The effects different weight ratios PVDF PVDF-HFP in a composi...

A single-use electrochemical sensor using ionic liquid mediated hollow fiber-graphite working electrode was fabricated for the first time. The screening tool was developed by coupling this electrode with differential pulse voltammetry (DPV) for in-situ pre-concentration and determination of Zn(II) and Cu(II). In our plot, porous polypropylene hollow fiber membrane divided into pieces of 2 cm, t...

Zeolitic imidazolate framework-93 (ZIF-93) continuous membranes were synthesized on the inner side of P84 co-polyimide hollow fiber supports by microfluidics. MOFs and polymers showed high compatibility and the membrane exhibited H2-CH4 and CO2-CH4 separation selectivities of 97 (100 °C) and 17 (35 °C), respectively.

The surface properties of TiO2-PVDF nanocomposite membranes were investigated by incorporating different chemically modified TiO2 nanoparticles into the poly (vinylidene fluoride) (PVDF) matrix. The nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. The membrane surface morphologies were investigated by using SEM and AFM and related...

An attempt to reduce the number of steps and hence the overall costs involved in the preparation of hydrophilic flat sheet poly(vinylidene fluoride) (PVDF) membranes was made by adding PVDF polymer powders directly to an amphiphilic copolymer mixture containing PVDF grafted with poly(ethylene glycol) methyl ether methacrylate (PEGMA) (PVDF-g-PEGMA), solvent and unreacted PEGMA from the atom tra...

In the Introduction section of this Research Article, description on membrane geometry was incorrect. The first sentence fourth paragraph in section, “Herein we prepared high-silica CHA zeolite membranes ceramic hollow fiber substrates for Kr/Xe separation.” should be revised to read disk This change does not affect interpretation data and conclusions, but guarantees a consistent with other sec...
