摘要:

The volume-dependence of the structure factors of the one component plasma (OCP) and of the hard sphere fluid (HSF) are calculated from data derived from computer experiments. In the OCP case the results are in essential agreement with the predictions of a simple formula due to Egelstaffet al.which the latter writers have shown to apply to rubidium. This provides further evidence that the OCP is a suitable reference system for the liquid alkalis. The results for the HSF, as expected, do not obey the formula of Egelstaffet al.and presumably are more representative of polyvalent liquid metal behaviour.

摘要:

It has been shown thatV1(T, p, x1) =V10(T, p- π1) and thatV2(T, p, x2) =V20(T, p- π2), where π1is the osmotic pressure of the solvent in a binary solution and π2is the osmotic pressure of the solution solute. An increase in pressure applied to the solution, the pure solvent and pure solute fromptop+ Δpcompresses the solution solvent and pure solvent by equal fractions

摘要:

Excess volumes on mixing for binary mixtures of trichloroethylene with aliphatic ketones and alicyclic ketones have been determined dilatometrically. TheVEdata are reported over the complete mole fraction range at 303.15K amd 313.15K. Aliphatic ketones include methylethylketone, methylpropylketone, diethylketone and alicyclic ketones are cyclopentanone and cyclohexanone The measuredVEvalues are negative over the entire composition range. Temperature effect is also studied for all the binary systems. The observed values are interpreted in terms of (i) formation of hydrogen bond and (ii) dipole-induced dipole interactions between the dipole of the ketone and trichloroethylene.

摘要:

The dielectric measurements on the mixtures of benzaldehyde with phenol and cresols as well as of acetophenone withn-butylalcohol and phenol in carbontetrachloride have been made in the temperature range (290–318)K. The relaxation time of the complexed species have been calculated using Higasiet al., method. With the help of the equation proposed previously in one of our earlier papers, the equilibrium constants along with thermodynamical parameters for association process have been evaluated using different values of constantsAandB.The fairly good agreement between the calculated values of equilibrium constant (K) and its literature values shows the applicability and reliability of the proposed equation and also the importance of the need for a detailed study in this direction.

摘要:

The bubble-point data were collected on a Swietoslawski type ebulliometer for the title systems each at 200 and 700 mm Hg. Calculated VLE data along with the activity coefficients and excess gibbs free energy values through the use of the Wilson equation are reported. The data are analysed for the nonideal behaviour of the systems. The pure-component Vapour-Pressure-temperature relationships are also presented.

摘要:

The Gaskell approximation for Structure Factors is calculated in the low wave vector region for liquid Aluminium, Lead and Rubidium using the standard pseudopotential formalism of Asheroft together with Vashishta-Singwi screening. The Gaskell approximation is found to produce only a small change to the random phase approximation in all cases studied.

摘要:

The temperature dependence of the enthalpy of the Te-rich eutectic Ge-Te alloy was measured by drop calorimetry in the crystalline, amorphous and liquid states using a high temperature Calvet calorimeter. This dependence leads to a second order transition which takes place around the eutectic temperature. Such a behaviour is explained by the destruction of the short range order in the liquid phase by heating.

摘要:

A first-principles nonlocal pseudopotential formalism is used to calculate the effective ion-ion pair potentialU(r)for liquid cesium at the melting point (28.4°C). The potentialU(r)is then used in a Monte Carlo simulation to obtain the pair correlation functiong(r).The static structure factorS(q)is calculated using the Fourier transformation ofg(r)forq> 0.6(a.u.)−1and Fowler's formula forq> 0.6(a.u.)−1and compared with X-ray and neutron scattering data. Good overall agreement is found between the calculatedS(q)and the experimental X-ray curve. In addition, the isothermal compressibility limit is satisfied at lowq.The first-principles pseudopotential form factor andS(q)are used self-consistently in Ziman's theory to calculate the electrical resistivity,p, and thermoelectric powerQ.Althoughpdiffers by a factor 2 with experimental data at 30°C, theQagrees with experiment in magnitude as well as sign. A possible explanation is given for the discrepancy inp.
