On permeability of corrugated pore membranes

open access: yesAIP Advances, 2020
Ceramic membranes have great potential for water treatment and filtering applications. However, one of the drawbacks of ceramic membrane filtration is its low permeability due to small functioning nanometer pore size. Increasing the membrane permeability

Pore size engineering of cost-effective all-nanoporous multilayer membranes for propane/propylene separation

open access: yesScientific Reports, 2023
In this study, a new multi-layer hybrid nanocomposite membrane named MFI/GO/ZIF-8 has been synthesized. This membrane combines three nanoporous materials with different morphologies in one membrane without using polymer materials. This allows access to a

Permeability-Selectivity Analysis of Microfiltration and Ultrafiltration Membranes: Effect of Pore Size and Shape Distribution and Membrane Stretching

open access: yesMembranes, 2016
We present a modeling approach to determine the permeability-selectivity tradeoff for microfiltration and ultrafiltration membranes with a distribution of pore sizes and pore shapes. Using the formulated permeability-selectivity model, the effect of pore

Role of the fast kinetics of pyroglutamate-modified amyloid-β oligomers in membrane binding and membrane permeability. [PDF]

open access: yes, 2014
Membrane permeability to ions and small molecules is believed to be a critical step in the pathology of Alzheimer's disease (AD). Interactions of oligomers formed by amyloid-β (Aβ) peptides with the plasma cell membrane are believed to play a fundamental

Sterilization of heparinized Cuprophan hemodialysis membranes [PDF]

open access: yes, 1996
The effects of sterilization of dry heparinized Cuprophan hemodialysis membranes by means of ethylene oxide (EtO) exposure, gamma irradiation, or steam on the anticoagulant activity and chemical characteristics of immobilized heparin and the permeability

High membrane permeability for melatonin [PDF]

open access: yesJournal of General Physiology, 2015
The pineal gland, an endocrine organ in the brain, synthesizes and secretes the circulating night hormone melatonin throughout the night. The literature states that this hormone is secreted by simple diffusion across the pinealocyte plasma membrane, but a direct quantitative measurement of membrane permeability has not been made.
