The application of organic-inorganic nanocomposite membranes allows for a synergy between the desirable thermal and mechanical properties inorganic materials with reactivity, dielectric properties, durability, flexibility, processability polymeric materials. Proton exchange membrane fuel cells (PEMFCs) suffer from some problems including water content management, carbon monoxide poisoning, hydr...

in this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. aqueous solution of 1-methyl-2-pyrrolidine (nmp) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. the morphology of fabricated membranes...

Through dip coating method monodisperse nickel nanoparticles assisted carbon membrane was prepared on porous alumina disc support. The solution by blending of thermally stable polymer polyphenylene oxide (PPO) and labile polyvinylpyrrolidone (PVP) followed addition nanoparticles. Size nanoparticles, surface porosity, average pore size, element composition optical properties the were investigate...

BACKGROUND Extracorporeal carbon dioxide removal has been proposed to achieve protective ventilation in patients at risk for ventilator-induced lung injury. In an acute study, the authors previously described an extracorporeal carbon dioxide removal technique enhanced by regional extracorporeal blood acidification. The current study evaluates efficacy and feasibility of such technology applied ...

The effect of the phospholipid acyl chain carbon number on the activity of the branched-chain amino acid transport system of Lactococcus lactis has been investigated. Major fatty acids identified in a total lipid extract of L. lactis membranes are palmitic acid (16:0), oleic acid (18:1) and the cyclopropane-ring containing lactobacillic acid (19 delta). L. lactis membrane vesicles were fused wi...
