Environmentally-safe anion exchange membranes of PVA/PDDA/SiO2composite for reverse electrodialysis
Anion Exchange Membranes (AEMs) are positively charged polymer membrane used in many applications. In RED systems, AEMs could be used to separate ions to produce energy, and on the other hands remove unwanted molecules in wastewater.

Advanced Development of Molecularly Imprinted Membranes for Selective Separation
Molecularly imprinted membranes (MIMs), the incorporation of a given target molecule into a membrane, are generally used for separating and purifying the effective constituents of various natural products. They have been in use since 1990.

The Glomerular Endothelium Restricts Albumin Filtration
Inflammatory activation and/or dysfunction of the glomerular endothelium triggers proteinuria in many systemic and localized vascular disorders. Among them are the thrombotic microangiopathies, many forms of glomerulonephritis, and acute inflammatory ...

Permselectivity in thin membrane nephropathy. [PDF]
The glomerular permselectivity to polydisperse neutral dextrans was compared in 6 patients with thin membrane nephropathy (TMN) and 10 healthy controls. Despite having normal renal hemodynamics and minimal proteinuria, the patients with TMN had significantly increased fractional clearance of neutral molecules with Stokes radius > 42 A.

Large molecules pass the biological membranes through accessory elements, either carriers (ionophores) and/or water channels. Ionophores shield the charge of the target ion, enabling it to cross the membrane to be released on the other side.
