Gaseous diffusion in liquids
… molecular weights of the respective liquids. Diffusion of gases into nonpolar liquids have previously been measured by two techniques: (1) a pseudo-steady state technique developed by Hildebrand with diffusion through multiple capillaries and (2) a method by Walkley with diffusion through an …

The fundamentals of the separation of a mixture of hydrogen and carbon dioxide by gaseous diffusion
A gaseous diffusion column was designed, constructed, and its operation tested with a system of electrolytic hydrogen and carbon dioxide. The column contained one diffusion unit with two 6-inch diameter barrier areas. In the preliminary tests the flow rates of the hydrogen-carbon dioxide mixture …

Separation of fission products from irradiated uranium by peroxide precipitation
… has been utilized for relatively pure fuel from gaseous diffusion plants or in purifying column extraction products from salvage processes. A search of the unclassified literature had rendered no information upon the feasibility of separating fission products and fuel cladding materials by …

SIMULATION OF COMPLEX MULTIPHASE, MULTI-COMPONENT, REACTING FLOWS IN POROUS MEDIA
… a porous medium. Chemical reactions, adsorption, gaseous diffusion and changes in porosity and permeability are important in one or both of these problems. These matters are discussed in general in the first few chapters of the thesis. Several models for the spontaneous combustion of coal that …

The chemical work of Thomas Graham
… that there was a partial analogy between gaseous and liquid diffusion; both processes depended ultimately on inherent molecular motions. The chemical affinity of water for different substances connected his studies of acids and salts with the liquid state. His first chemical investigations …

Optimization and analysis of the laser isotope separation technique SILEX and ensuing proliferation ramifications
… greater proliferation risk than centrifuge or gaseous diffusion technology, to claims by scientists that it is not possible to use the technology to produce greater than 50% enriched U-235. A rigorous and holistic view of the technology will better inform policy by improving the accuracy of …
