Summary: This study assessed and compared the thermodynamic properties of different sorbents and found that carbon-based sorbents and MOFs had lower sorbent-adsorbate interactions and were suitable for adsorption steps with less heat release. NPS and Cr-MIL-101 showed entropic advantages for water recovery/removal. The results highlight the importance of enthalpy and entropy in selecting favorable conditions for adsorption-desorption cycles.

Summary: This paper presents a novel formulation representation of the molar Gibbs free energy for sulfur dioxide (SO2) that relies solely on the experimental values of six molecular constants. In contrast to conventional explicit representations, which require fitting a large amount of experimental spectroscopic or calorimetric data, the proposed formulation eliminates the need for adjustable coefficients. Furthermore, the paper also develops a formulation representation of the molar entropy for SO2 based on the Gibbs free energy representation. The predicted values of reduced molar Gibbs free energy and entropy show low average absolute deviations from the data reported in the National Institute of Standards and Technology database, indicating the practical engineering value of the proposed formulation for SO2.

Summary: This paper presents a novel measurement method based on the finite volume method (FVM) for measuring the concentration-dependent mutual diffusion coefficient D(C) in binary solution. The measurement principle was derived by integrating Fick's second law and establishing discretization equation. The method was validated through experiments and a semi-empirical correlation was built to study the temperature and concentration influences on the diffusion coefficient D.
