摘要:

Within the framework of MSA exact solution for charged hard spheres with equal diameters found by Waisman and Lebowitz for Coulomb part of free energy and Mansooriet al., approximation for hard sphere contribution characteristics of evaporation phase transitions in terms of the equation of state have been estimated. The phase diagram has been evaluated and the behaviour of thermodynamic properties studied in a wide range of temperature and pressure for the example close to KF system. The position of the critical point is in accordance with the earlier determination of Telo da Gama, Evans and Sluckin using generalised MSA. Numerical values of the coefficients in the expansion of the relative deviation in pressure in powers of temperature and order parameter have been simply estimated near the critical region. Temperature and pressure dependencies of entropy and isothermal compressibility are typical enough for fluid systems, notwithstanding the collective nature of ionic interactions. In addition, the known Kauzman entropy paradox arises at low temperatures.

摘要:

We consider the uniform motion of a drop of one fluid moving in another immiscible, unbounded, fluid. We examine the condition of normal stress balance across the interface. Consistent application of this condition to linear order in the velocity requires the introduction of a new parameter, Δ, which takes into account deformations of the drop from a spherical shape. Imposing a condition for the critical size of these deformations allows us to predict the maximum size of the drop for a given terminal velocity. For the case of raindrops this gives a maximum size of approximately 2 millimeters.

摘要:

The structural modifications induced in a model of molten CuCl by quenching the chlorine component into a microporous disordered matrix are evaluated using the hypernetted-chain closure in Ornstein-Zernike relations for the pair distribution functions in random systems. Aside from obvious changes in the behaviour of long-wavelength density fluctuations, the main effect of partial quenching is an enhanced delocalization of the Cu+ions. The model suggests that the ionic mobility in a superionic glass is enhanced relative to the melt at the same temperature and density. Only very minor quantitative differences are found in the structural functions when the replica Onstein-Zernike relations derived by Given and Stell for a partly quenched system are simplified to those given earlier by Madden and Glandt.

摘要:

Ultrasonic velocity, denisty and viscosity of the quarternary systems consisting of water, glycerol and carbonato-bis-(ethylene diamine) cobalt (III) chloride are measured at 303.15 K for different proportions of the component to evaluate various acoustic parameters. Apparent molal volume studies have also been made for the solutions of the complex at the same temperature. The results are discussed here in terms of ion-solvent, ion-ion interaction and of structural effects on the solvent in solution.

摘要:

The aggregation kinetics of a lattice model of aligned dipoles is examined as a simple model for electrorheological or magnetorheological fluids. We have found that the mechanism of cluster growth depends on time. Initial growth of clusters is dominated by monomer field-induced migration, but subsequent growth of the clusters at later stages is strongly dependent on monomer depletion and anisotropic diffusion of the aligned clusters.

摘要:

The conductometric, viscometric and ultrasonic velocity measurements of the solutions of terbium laurate in benzene-methanol mixture (7:3 v/v) were carried out at 40 ± 0.05°C. The conductivity results showed that the soap behaves as a weak electrolyte in dilute solutions. The viscosity results were explained on the basis of equations proposed by Einstein, Vand, Moulik and Jones-Dole and the values of molar volume evaluated by using Einstein's and Vand's equations were in close agreement. The ultrasonic velocity measurements were used to evaluate various acoustic parameters. The results showed that the soap-soap interactions are weaker than soap-solvent interactions in dilute solutions and the soap molecules do not aggregate below the critical micelle concentration in dilute solutions.
