Forum on osmosis. IV. More on osmosis and diffusion
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1979A brief summary is presented of the Gibbsian view of chemical drives and of its mechanical interpretation, including a description of the “diffusion force” that arises from an interplay between fluctuations and dissipation. Osmotic flows are shown to be driven by diffusion forces acting at the membrane interface, and not by the effects of Hammel and ...

Quarterly Reviews of Biophysics, 1979
It has virtually become a truism that osmosis, and the inseparable array of related processes comprising ultrafiltration, diffusion, anomalous osmosis, etc., has found its final and lasting exposition to which anything can only be added by way of a few finishing touches. This view, as I shall attempt to show, is quite wrong, if for no other reason than

Two variational principles control isotonic osmosis and reverse osmosis: the principle of least dissipation of energy referring to a definite time integral and the principle of least constraint referring to the stationary (extremum) value of a volume integral.An extended form of the Nernst–Planck equation resulting from the time variation has been ...

Volume 7: Engineering Education
Abstract This paper presents an improved model for the phenomenon of osmosis. It extends the excellent work introduced by J.H. van’t Hoff more than 130 years ago. The van’t Hoff model was a major improvement to the previous 100 years of research and experiments and has served as a solid place holder to support the tremendous advances ...

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.
