Osmotic mass transfer in the yeast Saccharomyces cerevisiae.
P Gervais,L Beney +1 more
TL;DR: The use of ultra-rapid mixing systems allowed us to show that yeast cells respond to osmotic upshifts within a few milliseconds and to determine a very high hydraulic permeability for yeast membrane, which suggested that yeast membrane may contain facilitators for water transfers between intra and extracellular media.
Reverse Osmosis Process Membranes Modeling – A Historical Overview
TL;DR: An overview of the state-of-the-art area of mathematical modeling for reverse osmosis (RO) process is given in this paper, where the authors present an overview of RO membrane modification.
Journal ArticleDOI
Hydrostatic pressures developed by osmotically swelling vesicles bound to planar membranes.
TL;DR: The steady-state delta P, from the equations of irreversible thermodynamics governing water and solute flows, is calculated, for two general methods of osmotic swelling, where delta P approaches the theoretical limit set by the concentration of the impermeant solute.

Mechanisms of Transport through Reverse Osmosis Membranes
TL;DR: A review of reverse osmosis membrane transport mechanisms can be found in this article, where a quantitative description of penetrant solution and diffusion in microheterogeneous media as described by the dual sorption theory and a mechanism based on irreversible thermodynamics are also discussed.

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.
