We report computer simulations of semi-permeable membranes used to study electrolyte solutions undergoing osmosis, reverse osmosis, and electro-osmosis. The semi-permeable membrane, which is atomistic in nature, has been modeled using a novel technique developed by us recently. Our results show a rather significant role played by solvation forces, which cause the formation of large molecular clusters...
Many papers have been published which are generalizations or refinements of the basic theoretical analyses of Kirkwood and Frőhlich. Several theories often fit a more or less limited range of experimental results so that one feels that agreement with experimental dielectric constant values alone is not a very conclusive check on the basic assumptions of these theories. Multiplicity of theories rather...
No fundamental changes in dielectric theory have occurred during the past year although certain advances in detail and generalization have been made. An investigation of the influence of molecular shape (1) on the dielectric constant of polar liquids has led to a modification of Onsager's equation. Dipole moment values deduced from the new equation agree rather better with the gas values. The remaining...
The paper gives a calculation of the static dielectric constant of ice using Frőhlich's general theory of the static dielectric constant and a recent generalization of it for anisotropic materials2. The calculation is made with the principal assumption that an ice crystal containing N molecules can take up any of (3/2)N configurations, each with equal probability, in the manner proposed by Pauling...
