TL;DR: In this article, a semi-empirical equation of Gibbs free energy of mixing ΔG for the system polystyrene in methylcyclohexane has been determined based on the Flory−Huggins equation by using a series of coexistence curve data.
Abstract: A semiempirical equation of Gibbs free energy of mixing ΔG for the system polystyrene in methylcyclohexane has been determined based on the Flory−Huggins equation by using a series of coexistence curve data. The functional form of the interaction parameter g with respect to chain length of the polymer was determined so as to express the critical universality. The resultant equation of ΔG was used to prepare microcapsules of controlled size distribution by means of coacervation in the spinodal region.

TL;DR: In this article, an empirical method of determination of the activity coefficients and activities was applied to the binary H2O-H2SO4 system, which gave thermodynamically consistent definitions and satisfy the Gibbs-Duhem equation under the entire concentration range, unlike most molality-based and ionic interaction models.
Abstract: An empirical method of determination of the activity coefficients and activities was applied to the binary H2O–H2SO4 system. This component-based treatment was shown to give thermodynamically consistent definitions and satisfy the Gibbs–Duhem equation under the entire concentration range, unlike most molality-based and ionic interaction models. The selection of the reference state is important, and any derivations from the experimental data must follow thermodynamic rules. The empirical functions are extendable to the whole concentration range, including areas where water is not a solvent.
