Excess enthalpies and Gibbs free energies for nitrogen + methane at temperatures below the critical point of nitrogen
TLDR
In this paper, mixing calorimetry has been used to determine the excess enthalpy HE as a function of composition for liquid mixtures of nitrogen + methane at 91.5 and 105.0 K. Good agreement is found between the present results and a number of other recent studies.About:

A geochemical model of non-ideal solutions in the methane–ethane–propane–nitrogen–acetylene system on Titan
TL;DR: In this paper, the van Laar model was used to calculate the solubilities of gases and solids in liquid hydrocarbons at cryogenic temperatures, which can be extended to any number of components while maintaining thermodynamic consistency.

Determination of Activity Coefficients from total pressure measurements
TL;DR: In this paper, a method of least squares is described for calculating activity coefficients from results of total vapour pressure measurements, and a method for computing activity coefficients is proposed for calculating the activity coefficient from the results of a single measurement.
