Computer simulation of osmosis and reverse osmosis in solutions
Chemical Physics Letters, 1994Computer simulation studies using the method of molecular dynamics have been carried out to investigate osmosis and reverse osmosis in solutions separated by semi-permeable membranes. Our results show both osmosis and reverse osmosis, as well as a smooth transition between the two when either the solution concentration is changed, or the density ...

Osmosis and intermolecular force
Journal of Theoretical Biology, 1984A hypothesis concerning the molecular-dynamical basis of osmosis is presented. According to this hypothesis, osmosis results from the attractive force between solute and water molecules, and the exclusion of the solute from the water transport channels of the membrane. Based on this hypothesis, the osmotic process is predicted to involve a large number

Forum on osmosis. II. A criticism of "solvent tension" in osmosis
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1979Concepts about the liquid state that are inconsistent with the facts are noted, and solvent under tension is one of them. Osmosis is not present in a solution: it is a process in the presence of a semipermeable membrane that can be quantified by the operation of applying a hydrostatic pressure.

Osmosis, diffusion, convection
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1978We present a tutorial on the mechanisms of and connections among osmosis, diffusion, and convection. For simplicity, we consider only two-component nonelectrolyte solutions under isothermal conditions. Further, we confine our attention to laminar convection with application to the case of flow through narrow channels, as might occur in membranes ...

PROF. SCHREINEMAKERS has been engaged since 1924 in studies in osmotic phenomena, which have hitherto only been available in Leyden dissertations and the publications of the Amsterdam Academy of Science. In this book he gives a collected account in English of his researches, which will be of great interest to those who are concerned with the transport ...

The van’t Hoff formula for osmotic pressure, which is identical in form to the formula for ideal gas pressure, is a direct outcome of the second law of thermodynamics. The formula is derived by applying a closed cycle reversible and isothermal process, following an argument in Fermi’s book on thermodynamics.

Abstract Building on the results of the previous chapter, this chapter extends the analysis of colligative properties to mixing and osmosis, with an analysis of osmotic pressure and also the important industrial process of reverse osmosis.

They are a type of small parrot with a pink face and a red or black head and are found in Madagascar or Abyssinia. They are said to be “inseparable.” As a symbol of symbiosis and complete union they represent the most extreme form of a certain ideal of love and conjugality. Whatever one does the other does too. If one eats, the other eats.

Molecular mechanisms of osmosis
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1989Osmosis across a semipermeable membrane is usually treated in terms of thermodynamics, but the equations for osmosis can also be derived from kinetic considerations. Since fewer solvent molecules bombard the semipermeable membrane from the solution side, a kinetic pressure difference (osmotic potential) is generated into pore openings.

A fresh view for explaining the process of osmosis and the phenomenon of osmotic pressure is presented. The process of osmosis was identified and modeled more than 100 years ago. Others have unsuccessfully challenged the original model developed by J.H. van’t Hoff.
