Transfer of neutral organic solutes during desalination by electrodialysis : influence of the salt composition
TL;DR: In this article, the authors investigated the transfer of neutral organic solutes (acetic acid, phenol, glucose) through ion exchange membranes, focusing on the influence of the salt (NaCl, MgCl2, Na2SO4).

Overview of theories for water and solute transport in9 UF/RO membranes
TL;DR: In this paper, the applicability of various models for the transport of water and solute in UF/RO membranes is briefly outlined and the selectivity of various solutes in ultrafiltration and reverse osmosis is further discussed.

Temperature dependence of mature mouse oocyte membrane permeabilities in the presence of cryoprotectant.
TL;DR: Values generated for Lp and associated Ea were similar to those found for mouse oocytes in the absence of cryoprotectant, while omega and its Eawere similar toThose found for oocytes of other species.
Journal ArticleDOI
Plasma membrane water permeabilities of human oocytes: the temperature dependence of water movement in individual cells.
TL;DR: It is apparent that pre‐ovulatory human oocytes express a range of biological diversity in terms of membrane water transport, and this fact needs to be considered when attempting to formulate cryopreservation protocols for storage of these oocytes.

Analysis of lymphatic protein flux data: II. Effect of capillary heteroporosity on estimates of reflection coefficients and PS products
TL;DR: The method for estimating the capillary membrane reflection coefficient and permeability-surface area product for the plasma proteins using various lymph protein flux states is applied to data generated with a two-pore computer model where the pores have unequal reflection coefficients.

Filtration, diffusion and molecular sieving through peripheral capillary membranes; a contribution to the pore theory of capillary permeability.
TL;DR: Theoretical and experimental studies on the sieving of molecules by ultrafiltration through porous membranes indicate that an effective pore diameter of at least IOO A would be required to explain permeability of this magnitude.

Passage of Molecules Through Capillary Walls
TL;DR: A wealth of evidence supports the view that the exchange of materials through the walls of living capillaries takes place by physical processes which involve no expenditure of energy on the part of the capillary endothelial cells themselves.
