    Notes: The scaled particle theory for nonadditive hard disks developed by Tenne and Bergmann [J. Chem. Phys. 70, 1952 (1979)] has been studied for binary mixtures of equal size particles with various values of the nonadditivity parameter and mole fraction. Above a certain special density, we find that there are two branches of solutions of the equations determining the thermodynamic properties of the system. An argument is given that one of these branches is unphysical and should be discarded. Nevertheless, it explains a kink in the free energy vs density plot, and other anomalous features of the results of Tenne and Bergmann. We conclude that the existence of a phase transition has not yet been established for this approximation. It is pointed out that the theory does not give scaled particle theory for pure liquids in the limit of zero concentration of one component.

    Notes: The scaled particle theory of nonadditive hard disks or spheres of Tenne and Bergman, studied numerically by us in two previous papers, has been modified by relaxing the requirement that the particle radius scaling respect the nonadditivity out to arbitrarily large radii. The resulting theory is much simpler to implement numerically, while the results are comparable to those of the previous theory. A comparison is made between the predictions of phase separation of the present theory and those of numerical simulations.

    Notes: The scaled particle theory of Tenne and Bergmann [J. Chem. Phys. 70, 1952 (1979)] studied in paper I [J. Chem. Phys. 88, 1235 (1988)] has been examined for fluid–fluid phase equilibria in binary solutions of equal size particles. For a large deviation from additivity, changes in curvature of the Gibbs free energy identify regions of complete miscibility, partial miscibility, and immiscibility. The compositions of coexisting phases are determined using the double tangent construction. The simplicity of the intermolecular potential leads to an inverse relationship between the pressure–mole fraction phase diagram at constant temperature and the temperature–mole fraction phase diagram at constant pressure. The binary solutions are found to possess a lower solution critical pressure at constant temperature and an upper solution critical temperature at constant pressure. The critical exponent β is found numerically to be classical as would be expected from a scaled particle theory. The phase equilibria reported in the present paper differ from those reported by Tenne and Bergmann which appear to result from nonphysical mathematical vagaries of the model already discussed in paper I.

    Notes: The integral equations of the generalized mean spherical approximation (GMSA) are solved for the case of a primitive model fused salt near a wall. In particular, the charge density profile near the wall is determined as a function of the charge on the wall. The input data are the bulk pair correlation functions of the ions determined by the GMSA. The results are presented in graphical form. There are, at the present time, no simulation data or experiments with which to compare the results.

    Notes: The effects of image charges on ions and polar particles near boundaries are calculated for several simple models. These are: dielectric friction of a translating charge and of a rotating dipole, and the electrostatic contribution to the hydration energy of an ion, all near a boundary. Image charge induced changes in dielectric friction and electrostatic free energy are found to be minor for molecular size particles, but appreciable for larger particles, e.g., macromolecules near membranes.

    Notes: Abstract An analysis is made of the motion of a spherical Brownian particle whose surface can diffusely reflect the molecules of an equilibrium host gas. The analysis is based on Newton's second law and a limiting form of Markov's method. It is shown, both for specular and diffuse reflections, that equipartition of energy is a consequence of the dynamics and randomness of the motion. In addition, it is demonstrated that the diffusion coefficient can depend on the temperature of the particle. The entire analysis is restricted to the case for which the Knudsen number of the particle is large compared to unity.
