TLDR
The equations derived here have been applied to various permeability measurements found in the literature, such as the penetration of heavy water into animal cells, permeability of blood vessels, threshold concentration of plasmolysis and relaxation experiments with artificial membranes.About:

Experimental study of the osmotic behaviour of reverse osmosis membranes for different NaCl solutions and hydrostatic pressure differences
TL;DR: The osmotic water flux through the membranes was found to increase nonlinearly with respect to the increasing concentration difference over the membrane, leading to non-constant values for apparent water permeability as discussed by the authors.

Elasticity of the Porcine Lens Capsule as Measured by Osmotic Swelling
Tracy A. Powell,Rouzbeh Amini,Alina Oltean,Vincent A. Barnett,Kevin D. Dorfman,Yoav Segal,Victor H. Barocas +6 more
TL;DR: Although limited by being a single measurement on a heterogeneous tissue, osmotic swelling provides a quantitative assessment of the stiffness of the lens capsule without requiring dissection or manipulation of the lenses, the new method could be useful for small animal models.

Derivation and Application of Effective Interface Conditions for Continuum Mechanical Models of Cell Invasion through Thin Membranes
TL;DR: In this article, the authors consider a continuum mechanical model of cell invasion through thin membranes, which consists of a transmission problem for cell volume fraction complemented with continuity of stresses and stability of stresses.
Journal ArticleDOI
Colloid-interface interactions initiate osmotic flow dynamics
TL;DR: In this article, a model that describes the role of colloid-interface interactions in the dynamics of the osmotic flows through a semi-permeable interface is presented.

TL;DR: Comparisons with experimental results from the literature revealed that the DP models predicted coagulation zone sizes that are closer to the experimental values than the SP models, which supports the hypothesis that the SP model is a poor choice for simulating the outcome of saline-infused RFA.

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.
Journal ArticleDOI
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.
