Implementation of Spiegler–Kedem and Steric Hindrance Pore Models for Analyzing Nanofiltration Membrane Performance for Smart Water Production

open access: yesMembranes, 2018
A predictive model correlating the parameters in the mass transfer-based model Spiegler–Kedem to the pure water permeability is presented in this research, which helps to select porous polyamide membranes for enhanced oil recovery (EOR ...

NMR studies of membrane structure and dynamics [PDF]

open access: yes, 1978
Over the past decade, there has been considerable interest in the motional state of the phospholipid bilayer membrane. The motivation underlying these efforts has been the contention that the phospholipid bilayer is the basic matrix in which membrane ...

Alcohol Diffusion in Alkali-Metal-Doped Polymeric Membranes for Using in Alkaline Direct Alcohol Fuel Cells

open access: yesMembranes, 2022
The alcohol permeability of anion exchange membranes is a crucial property when they are used as a solid electrolyte in alkaline direct alcohol fuel cells and electrolyzers.

Experimental study of the effects of hypochlorite on polysulfone membrane properties [PDF]

open access: yes, 2006
Although chemical solutions are widely employed to clean membranes, they can also be responsible for changes in membrane properties. The two major drawbacks are then either the functional properties of the membrane gradually change, so the production can

PERMEABILITY OF MEMBRANES OF DEAD FETUS [PDF]

open access: yesObstetrical & Gynecological Survey, 1971
Membranes of dead fetuses showed a three-fold increase in permeability to the haemoglobin molecule when compared with normal and stored membranes. The friability of some of these membranes was markedly increased and their strength and elasticity diminished.

Effect of montmorillonite on PEBAX® 1074-based mixed matrix membranes to be used in humidifiers in proton exchange membrane fuel cells

open access: yese-Polymers, 2020
To meet the increasing requirements of membrane humidification in proton exchange membrane fuel cells (PEMFCs), a series of montmorillonite (MMT)/PEBAX® 1074 mixed matrix membranes (MMMs) were fabricated ...

Graphene-polyelectrolyte multilayer membranes with tunable structure and internal charge [PDF]

open access: yes, 2020
One great advantage of graphene-polyelectrolyte multilayer (GPM) membranes is their tunable structure and internal charge for improved separation performance. In this study, we synthesized GO-dominant GPM membrane with internal negatively-charged domains,

Electrostatically gated membrane permeability in inorganic protocells [PDF]

open access: yes, 2013
Although several strategies are now available to produce functional microcompartments analogous to primitive cell-like structures, little progress has been made in generating protocell constructs with self-controlled membrane permeability.

Analysis of Antimicrobial-Triggered Membrane Depolarisation Using Voltage Sensitive Dyes

open access: yesFrontiers in Cell and Developmental Biology, 2016
The bacterial cytoplasmic membrane is a major inhibitory target for antimicrobial compounds. Commonly, although not exclusively, these compounds unfold their antimicrobial activity by disrupting the essential barrier function of the cell membrane.

Direct observation of defects and increased ion permeability of a membrane induced by structurally disordered Cu/Zn-superoxide dismutase aggregates. [PDF]

open access: yesPLoS ONE, 2011
Interactions between protein aggregates and a cellular membrane have been strongly implicated in many protein conformational diseases. However, such interactions for the case of Cu/Zn superoxide dismutase (SOD1) protein, which is related to fatal ...
