Nonscaling calculation of the effective diffusion coefficient in periodic channels

The Journal of Chemical Physics, 2017
An algorithm calculating the effective diffusion coefficient D(x) in 2D and 3D channels with periodically varying cross section along the longitudinal coordinate x is presented. Unlike other methods, it is not based on scaling of the transverse coordinates, or the smallness of the width of the channel. The result is expressed as an integral of specific

Effective diffusion coefficient of sucrose in calcium alginate gel

Enzyme and Microbial Technology, 1990
The effective diffusion coefficient of sucrose in 5% calcium alginate gel containing 41.6 g.d.c. l-1. Saccharomyces cerevisiae was investigated. Both free and immobilized S. cerevisiae in 0.175 cm and 0.3 cm diameter particles were used and the reactions were achieved in a medium containing 100 g l-1 sucrose and 0.05 M CaCl2.

?Uphill? hydrogen diffusion effects and hydrogen diffusion coefficients in palladium

International Journal of Hydrogen Energy, 1997
Information concerning measurements of hydrogen diffusion coefficients over α- and β-phase ranges of hydrogen content in the palladium/hydrogen system is summarized. The utilization of palladium as a hydrogen purification membrane has constituted a background for observations of “uphill” hydrogen diffusion effects.

Effect of electrolytes on the self-diffusion coefficient of water

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1976
The self-diffusion coefficient of water in aqueous solutions of various electrolytes at a concentration of 0.1 mol dm–3 has been measured at 25°C by using the diaphragm cell technique with deuterium as tracer. The data are correlated with the viscosity B-coefficients and the entropies of hydration.
