Structural Order in the Hydration Shell of Nonpolar Groups versus that in Bulk Water

G Graziano - ChemPhysChem, 2024 - Wiley Online Library
The poor solubility of nonpolar compounds in water around room temperature is governed

How far is “bulk water” from interfaces? Depends on the nature of the surface and what we measure

VR Hande, S Chakrabarty - The Journal of Physical Chemistry B, 2022 - ACS Publications
Using systematic molecular dynamics (MD) simulations, we revisit the question: At what
distance from an interface do the properties of “bulk water” get recovered? We have …

How do water-mediated interactions and osmotic second virial coefficients vary with particle size?

H Naito, T Sumi, K Koga - Faraday Discussions, 2024 - pubs.rsc.org
We examine quantitatively the solute-size dependences of the effective interactions between
nonpolar solutes in water and in a simple liquid. The potential w (r) of mean force and the …

Remarks on the hydration entropy of polar and nonpolar species

A Bologna, G Graziano - Journal of Molecular Liquids, 2023 - Elsevier
Around room temperature, experimental hydration entropy values are large negative,
