Advanced Ionic Liquid-Based Mixed Solvent Systems

Dear Colleagues,

Over the past few decades, there has been a dramatic surge in the number of articles published in the literature that focus on (room-temperature) ionic liquids.  Interest in these salts has caused research to soar past the point of being just a curiosity to one of extensive efforts aimed at understanding these materials.  As a result, ionic liquids are arguably among the most studied materials in the physical sciences. The tremendous amount of work by researchers across many disciplines arises from the ever-growing number of applications of ionic liquids in areas such as chemical synthesis, engineering, and fabrication of electrochemical devices, among many others.

It is often the case that applications of ‘new’ materials frequently outpace the development of a detailed, molecular-level understanding.  Therefore, the importance of building a predictive capability becomes necessarily and progressively more important. Appropriately, much of the research published to date (both theoretical and experimental) has focused on neat ionic liquids.  However, as the diversity of applications continues to expand, ionic liquids are being combined with molecular cosolvents to further enhance their utility.

While a significant amount of effort has been made to study molecular-level details concerning the structure, dynamics, and interactions in neat ionic liquids, there is much work to do on cosolvent-modified ionic liquid systems. The chemistry, physics, and engineering of ionic liquid systems requires both experimental and theoretical approaches to achieve the desired understanding of the underpinnings that drive the widening array of ionic liquid-based materials.  To this end, a complete picture will only be achieved when a concerted effort involving all available tools is applied. This Special Issue seeks to highlight new results that discuss the properties and applications of multicomponent ionic liquid-cosolvent systems toward the advancement of a more complete understanding of ionic liquid chemistry and engineering.

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. ChemEngineering 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 1600 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.
