TL;DR: In this paper, the phase equilibrium and interfacial properties of CO2+n-decane binary system were studied under different pressures, and it was shown that the adsorption of CO 2 is stronger than the diffusion of ndecane, which is beneficial for displacing CO2 from the pore surface.

TL;DR: In this article, the authors compared four methods to adjust the difference between the heat capacities of the gaseous and condensed phases to the reference temperature 298.15 K. The agreement among the four methods suggests that they will be reliable for other metal containing complexes for which limited thermodynamic data are available.
