New Insights into Thermodynamics of Solutes in Neat and Complex Solvents-Further Progress and Extensions

Dear Colleagues,

The field of the physicochemical characteristics of solute-solvent systems is simultaneously an old and new domain. This branch of physical chemistry covers many theoretical aspects and is fundamental to a plethora of practical applications. The value of solute concentration at the equilibrium state with a multicomponent liquid solution is still unpredictable, despite decades of theoretical disputes and experimental investigations. However, from the general point of view, the conditions of this state are quite clear and are conditioned by fundamental thermodynamic laws. Nevertheless, the existence of many factors affecting real systems means that saturate systems are still an interesting subject worth deeper exploration. This new Special Issue, being the continuation of a previous successful collection entitled "New Insights into Thermodynamics of Solutes in Neat and Complex Solvents", now provides space for further progress and extensions in this field.

Hence, I am happy to invite researchers involved in the field of solid-liquid (SLE) and liquid-liquid (LLE) equilibria to present their high-quality results in this forum, which is freely available for open access and discussion. All theoretical aspects using the current standards in quantum chemistry, chemometrics, deep learning, and other relevant approaches are welcomed. Additionally, methodological advancements in the field of solubility determination, extraction, crystallization, or new forms of drugs are within the scope of this forum. Likewise, reports regarding new biodegradable, nontoxic, and nonflammable biosolvents and other low-cost and greener organic solvents for a variety of processing purposes are greeted with enthusiasm. The application of liquid mixtures in pharmaceutical and analytical sciences and technological advancements are also within the multidisciplinary scope of this Special Issue.

We are looking forward to new, exciting manuscripts addressing the above and related topics and expanding the community of colleagues sharing ideas, achievements, and implementations.

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 250 words) can be sent to the Editorial Office for assessment.

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. Molecules is an international peer-reviewed open access semimonthly 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 2700 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.
