TLDR
In this paper, a new equation of state for rigid spheres has been developed from an analysis of the reduced virial series, which possesses superior ability to describe rigid-sphere behavior compared with existing equations.Abstract:
A new equation of state for rigid spheres has been developed from an analysis of the reduced virial series. Comparisons with existing equations show that the new formula possesses superior ability to describe rigid‐sphere behavior.read more

Association and Surface Properties of a Cyclic Block Copolymer of Ethylene Oxide and Butylene Oxide (Cyclo-B8E42) in Water
TL;DR: In this article, a cyclic copolymer of ethylene oxide and 1,2-butylene oxide (cyclo-B8E42) was prepared by cyclization of triblock copolymers, and its self-association and surface properties were studied by dynamic and static light scattering and surface tension.

Theory of phase equilibria and closed‐loop liquid–liquid immiscibility for model aqueous solutions of associating chain molecules: Water +alkanol mixtures
Daron G. Green,George Jackson +1 more
TL;DR: In this article, a simple perturbation theory is used to develop an augmented van der Waals equation of state which treats the asymmetry in the attraction which arise because of the directional hydrogen bonding sites, and the asymmetric in the repulsions caused by the molecular shape of the chains.

Electrolyte-moderated interactions in water/oil microemulsions
Brian Bedwell,Erdogan Gulari +1 more
TL;DR: Calje et al. as mentioned in this paper found that the effect of added electrolyte in W O microemulsions is opposite to that which is observed in aqueous micellar solutions and water-in-oil (W O ) microemulsion, here the addition of electrolyte decreases attractive interactions rather than increasing them.

Dynamics in an oil-continuous droplet microemulsion as seen by quasielastic scattering techniques
TL;DR: In this article, the bending elasticity of the surfactant film in an oil-continuous microemulsion was determined by means of neutron spin-echo spectroscopy and dynamic light scattering.

Comparison between different explicit expressions of the effective hard sphere diameter of Lennard-Jones fluid : Application to self-diffusion coefficients
TL;DR: In this paper, a comparison between different expressions of the effective hard sphere diameter (EHSD) method has been carried out and suggestions are given following the comparison, and it is found that the temperature-dependent Boltzmann EHSD and both temperature- and density-dependent Lado modified Weeks-Chandler-Andersen EHSd give the best results.

Analysis of Classical Statistical Mechanics by Means of Collective Coordinates
TL;DR: In this paper, the three-dimensional classical many-body system is approximated by the use of collective coordinates, through the assumed knowledge of two-body correlation functions, and a self-consistent formulation is available for determining the correlation function.

Statistical Mechanics of Rigid Spheres
TL;DR: In this article, an equilibrium theory of rigid sphere fluids is developed based on the properties of a new distribution function G(r) which measures the density of rigid spheres molecules in contact with a rigid sphere solute of arbitrary size.

Equation of State for Hard Spheres
TL;DR: In this paper, simple and exact expressions for the compressibility and pressure equations of state predicted by the Percus-Yevick equation for hard spheres were found for Wainwright and Alder.

Studies in Molecular Dynamics. II. Behavior of a Small Number of Elastic Spheres
B. J. Alder,T. E. Wainwright +1 more
TL;DR: In this article, the equation of state and the collision rate for systems ranging in size from four to 500 particles are described, and the dependence of the results on the number of particles is qualitatively discussed and insight is gained as to what is required of more accurate analytical theories.

Fifth and Sixth Virial Coefficients for Hard Spheres and Hard Disks
Francis H. Ree,William G. Hoover +1 more
TL;DR: In this paper, the modified stars contain both Mayer f functions and f functions (f≡f+1) and it is shown that the number of topologically distinguishable graphs occurring in the new expressions is about half the number required in previous expressions.
