Moderate Point: Balanced Entropy and Enthalpy Contributions in Soft Matter
@article{He2015ModeratePB, title={Moderate Point: Balanced Entropy and Enthalpy Contributions in Soft Matter}, author={Baoji He and Yanting Wang}, journal={arXiv: Soft Condensed Matter}, year={2015} }
Various soft materials share some common features, such as significant entropic effect, large fluctuations, sensitivity to thermodynamic conditions, and mesoscopic characteristic spatial and temporal scales. However, no quantitative definitions have yet been provided for soft matter, and the intrinsic mechanisms leading to their common features are unclear. In this work, from the viewpoint of statistical mechanics, we show that soft matter works in the vicinity of a specific thermodynamic state…

This model shows that the most likely behavior to be seen is linear S‐H compensation over a rather limited range of perturbations with a compensation temperature Tc = dΔH/dΔS within 20% of the experimental temperature.

The evidence for severe compensation is found to be weak in light of the large magnitude of and correlation between errors in experimental measurements of entropic and enthalpic contributions to binding, though a limited form of compensation may be common.

It is tentatively concluded that the pattern is real, very common and a consequence of the properties of liquid water as a solvent regardless of the solutes and the solute processes studied, and that liquid water plays a direct role in many protein processes and may be a common participant in the physiological function of proteins.

A general virial expansion is developed to describe the influence of molecular additives on the equilibrium self-assembly of proteins or other supermolecularly assembling species M in solution, which finds the increased stability of the assembled form of M is progressively compensated by attractive interactions that alter the enthalpy of assembly.

The results show that for a correct dissection of the cosolute-induced changes of the free energy into its enthalpic and entropic contributions, the temperature dependence of the heat capacity change needs to be explicitly taken into account.
