Representation of binary excess enthalpy data

An extensive test of five correlation relations for the concentration dependence of excess enthalpy of non-electrolyte solutions was carried out. The Redlich-Kister, root and reciprocal expansions, the SSF and Wilson equations were used to represent experimental data of 54 systems of different character. For the representation of data of symmetric and slightly asymmetric systems, we recommend the Redlich-Kister polynomial, more asymmetric systems are described excellently by the SSF equation.

Enthalpy Data

A survey of relations making it possible to predict ternary HE,s from binary data and of relations for representation of the concentration dependence of ternary HE,s is presented in this part. Altogether 13 prediction and 26 correlation relations (including some proposed recently) were tested using a thoroughly selected set of nine ternary systems. Relevant recommendations are given on the basis of the results obtained.

Resistivity temperature â€“ dependence and residual resistivity concentration-dependence in pure noble metals(Cu, Ag, Au) have been studied at low temperatures. Dominations of electron â€“ dislocation and impurity, electron-electron, and electron-phonon scattering were analyzed, contribution of these mechanisms to resistivity were discussed, taking into consideration existing theoretical models and available experimental data, where some new results and ideas were investigated.

Surface Tension Isotherms

The experimental study results of the melts concentration dependence of the surface tension of the four-component indium-tin-lead-bismuth system and its constituent binary systems of indium-tin, indium-lead, indium-bismuth, tin-lead, tin-bismuth, lead-bismuth are presented in the paper. It is shown that the concentration dependence of the melts surface tension of the In-Sn-Pb-Bi four-component system can be predicted from the data on ST (surface tension) values of lateral binary systems. Features in the ST isotherms in the form of a minimum are observed only in the indium-tin lateral system from all lateral binaries. A distinctive feature of the detected minimum is that the minimum depth slightly exceeds the experimental error. Therefore, in addition to the fact that the area of average compositions was studied more thoroughly, we carried out the surface tension measurements by two independent methods. The experimental data obtained by both methods coincide within the experimental error and indicate the extremum availability on ST isotherms. Thus, ST experimental studies by two independent methods confirmed the presence of a flat minimum on ST isotherms of the indium-tin binary system increasing the reliability of the obtained data. The obtained outcomes and their comparison with experimental data have shown that the considered models for predicting surface properties based on data due to similar properties of lateral binary systems adequately reflect the experimental dependences. However, the prediction model based on Kohler's method of excess values describes the experimental curves more accurately.
