Dear Colleagues,

The history of solvation thermodynamics is very long. Prior to the 1970s, there were several different definitions of the solvation quantities referred to as standard solution quantities, such as standard Gibbs energy and standard entropy of solution (or hydration, when the solvent is water). It is not clear which of these quantities is truly a measure of the Gibbs energy of interaction between the solute and the solvent.

Traditionally, solvation thermodynamics was studied within the context of thermodynamics. In this context, it could be studied only in the limit of very dilute solutions, i.e., in the concentration range when Henry’s law is obeyed.

In 1978, a new process of solvation was introduced along with the corresponding thermodynamic quantities (Ben-Naim 1978, 1987, 2006). With this new concept, the study of solvation became a powerful tool to probe the extent of interaction between the solute and the solvent, and the effect of the solute on various molecular distribution functions in the solvent.

Any article on new results, either theoretical, experimental or simulated, on solvation thermodynamics will be welcomed.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
