Electrostriction, ion solvation, and solvent release on ion pairing

Article Abstract:

The theoretical mean molar electrostriction volume of electrolyte solvents, deltaV(sub el)(Solvent) is calculated from their properties, the relative pressure derivatives of the density (compressibility) and permittivity and their second pressure derivatives. The molar electrostriction caused by an ion at infinite dilution is taken to be expressed by the elctrostrictive volume decrease that is by the differences of its standard partial molar volume in the solution and its intrinsic volume.

Calorimetric studies of solvates of C60 and C70 with aromatic solvents

Article Abstract:

A study was conducted to analyze the solution characteristics of C60 and C70 in aromatic solvents by examining their binary systems. Trends associated with the solubility characteristics of fullerenes were discussed against the thermodynamics of solution and solvate formation. Results indicated that the formation-incongruent melting of solid solvates results in a maxima in the temperature-solubility curves of fullerenes in aromatic solvents.

Solubility of C60 fullerene

Article Abstract:

The solubility of the C60 fullerene is determined by subjecting the most recent and comprehensive set of solubility data of C60 fullerene in various solvents at 298 and 303 K to multivariate stepwise linear regression applied as linear solvation energy approach. It was seen that the molar volume and solvent polarity decreased the solubility and the electron pair donation ability and polarizability enhanced solubility.
