Permselectivity of the glomerular wall examined with iron compound tracer [PDF]

open access: yes, 1977
Rat kidney endothelial cell morphology was examined after introducing iron colloid particles of positive or negative charge to investigate the relationship between the electric charge and permeation through the glomerular capillary.

Permselectivity in thin membrane nephropathy. [PDF]

open access: yesJournal of Clinical Investigation, 1994
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.

Synthesis and properties of a new AB-cross-linked copolymer membrane system [PDF]

open access: yes, 1993
The alcohol permeability and permselectivity properties as well as the morphology of membranes made of a newly developed AB-cross-linked copolymer system composed of elastomeric and glassy components were investigated.

Microemulsion breakdown by pervaporation technique: Effect of the alkyl chain length of n-alkanol, a cosurfactant of the microemulsion [PDF]

open access: yes, 2007
Two sets of microemulsions, cyclohexane- and water-rich ones, were prepared with the following n-alkanols as cosurfactants: n-propanol, n-butanol, n-pentanol, and n-hexanol.

Reverse electrodialysis – Multi effect distillation heat engine fed by lithium chloride solutions [PDF]

open access: yes, 2019
Salinity Gradient Heat Engines (SG-HEs) have been proposed as a promising technology for converting low-temperature heat into electricity. The SG-HE includes two different processes: (i) a salinity gradient process where the salinity gradient between two

Optimization of net power density in Reverse Electrodialysis [PDF]

open access: yes, 2019
Reverse Electrodialysis (RED) extracts electrical energy from the salinity difference between two solutions using selective ion exchange membranes. In RED, conditions yielding a large net power density (NPD) are generally desired, due to the still large ...

Scalable and highly selective graphene-based ion-exchange membranes with tunable permselectivity

open access: yesnpj 2D Materials and Applications, 2023
Graphene oxide (GO) membranes have been proved to be ion-selective thanks to their oxidized functional groups, which are naturally present on its surface. This ion selectivity, together with good mechanical strength, low cost, and simple synthesis, makes
