Vapor Pressure Measurements

Molar excess free energies of the systems dimethylsulfoxide–water and propylene carbonate–water have been calculated from static vapor pressure measurements at 25 °C. Enthalpies of mixing at low water concentrations have also been determined. Possible association interactions in these systems are discussed.

Radiotracer Study

SummaryA radiotracer study was made of caesium and chloride ion deposition on mild steel, premagnetited mild steel, stainless steel and zircaloy-2 specimens under oxidising conditions at room temperature and oxygenfree conditions at room temperature and 60° C. The results show that under any of the conditions examined uptake on stainless steel and zircaloy is low. With mild steel uptake is only low when the surface is premagnetited, and exposed to deoxygenated water at elevated temperatures. Results for anion deposition are interpreted with reference to the electrode potentials of the surfaces. Cation deposition is unrelated to electrode potentials and appears to be associated with the hydrous character of the oxide film.

Free Energy Of Mixing

Redlich−Kister (R−K) polynomials have been associated with the extended regular associated solution model to predict and explain the thermodynamic properties and structural properties of Al−Fe liquid alloy at 1873 K, 1973 K, 2073 K and  2173 K; 1873 K being its melting temperature. The thermodynamic properties, such as free energy of mixing and activities of free monomers ( and ) and structural properties, such as concentration fluctuation in long wave length limit, chemical short range order parameter and ratio of diffusion coefficients ( have been predicted at above stated temperatures. Renovated Butler model has been employed to predict the surface tension and surface segregation of the alloy at stated temperatures with the help of thermodynamic properties. Theoretical findings prevail that the tendency towards compound formation of the liquid alloy decreases with increase in its temperature beyond melting temperature. Eventually, its surface tension decreases and there is gradual exchange of atoms between the surface and bulk regions to maintain equilibrium at elevated temperatures. The liquid alloy under investigation thus shows ideal behaviours at higher temperatures. BIBECHANA 15 (2018) 60-69
