Two-Phase Systems: New Trends and Applications

Dear colleagues,

Two-phase systems are a technique for liquid–liquid fractionation, comprising aqueous two-phase systems, and recently have included systems with low or no water content in coexisting phases. These systems are initially formed from a pair of polymers dissolved in water above a critical concentration, and previously have also used salts, organic solvents, ionic liquids, and deep eutectic solvents as constituents. Nowadays, systems formed from low concentrations of water (alcohols + salts + water) or no water (ionic liquids + polymers + ethanol) have also been reported in the literature. Normally, biphasic systems are used in the bath process at a normal scale; however, continuous and intensifying processes are in development. This Special Issue presents a set of high-quality research focused on new trends in, and applications of, two-phase systems, such as the following: the use of new constituents and the construction of new phase diagrams for aqueous two-phase systems, as well as biphasic systems with no or low water content; new applications for obtaining biomolecules of interest for the cosmetics, pharmaceuticals and chemicals industries, in addition to potential use in analytical protocols. This issue also focuses on new reactor designs, continuous systems, and intensification procedures.

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.
