TL;DR: Membrane separations of interest here are not to be confused with barrier separations employed in the uranium enrichment plant at Oak Ridge, Tennessee as discussed by the authors, where isotopes of uranium hexafluoride were separated by the free-molecular or Knudsen flow of the gas mixture through the pores and orifices created within a porous nickel media which was sometimes referred as a membrane.
Abstract: Membrane separations of interest here are not to be confused with barrier separations of the type employed in the uranium enrichment plant at Oak Ridge, Tennessee There isotopes of uranium hexafluoride were separated by the free-molecular or Knudsen flow of the gas mixture through the pores and orifices created within a porous nickel media which was sometimes referred to as a membrane In barrier separation, an enrichment of gases of differing molecular weights is accomplished by the differing gaseous diffusion rates within the porous media By contrast the membranes of interest here are thin, dense, continuous films, typically formed from polymers The separation of species is accomplished by the dissolution of the gases in the polymer and their diffusion across the solid film thickness under a concentration gradient according to Fick's law This process is commonly referred to as membrane permeation

TL;DR: In this article, a heterogeneous reaction model is developed to represent the gas-solid reaction consisting of two-step reactions: formation of a solid intermediate on the core of unreacted solid and consumption of the solid intermediate.

TL;DR: In this article, a method for measuring the self-diffusion coefficient of a vapor by observing with a mass spectrometer the rate at which material enriched in one isotope diffuses into normal material in an apparatus of known geometry was reported.
Abstract: A method is reported for measuring the self-diffusion coefficient of a vapor by observing with a mass spectrometer the rate at which material enriched in one isotope diffuses into normal material in an apparatus of known geometry. A value of $\ensuremath{\rho}D$ (where $\ensuremath{\rho}$ is the density and $D$ the diffusion constant) was obtained for uranium hexafluoride at 30\ifmmode^\circ\else\textdegree\fi{}C. Knowledge of the viscosity together with the constants reported here allow calculation of the molecular force law.

TL;DR: For example, animals, not men, are the common experimental subjects in research designed to predict the behavior of radioactive nuclides in man as mentioned in this paper.This is true for uranium quite as much as for other nuclide; witness the abundance of experimental animal data contained in the preceding chapter relative to the amount of information available for presentation in the following pages.
