Special Issue Information
Dear Colleagues,
Polyethylene glycol (PEG) is an industrial chemical produced at about 500,000 tons per annum, mainly as an ingredient in personal hygiene and healthcare products. In contrast, this Special Issue focuses on research and development where PEG is the major component of the system, motivated by its non-toxicity, biodegradability, low vapor pressure, as well as its solvent characteristics. Areas of interest include a) PEG as a green chemical solvent for chemical synthesis including mixed solvent systems such as deep eutectic solvents (DEP) or PEG co-solvent mixtures; b) applications where PEG is the main component of the system such as, for example, in heat transfer fluids or in gas absorption applications; c) research and development of PEGylated chemicals such as PEGylated ionic liquids or PEG-related nonionic surfactants that are used as chemical solvents or as the main component in practical applications; and d) fundamental theoretical and experimental research towards a better understanding of PEG at the molecular level and its resulting structure-property relationships. The goal of this Special Issue is to showcase the importance of PEG in a variety of developing research directions and, by doing so, promote seminal research involving PEG through new collaborative efforts of researchers across divergent fields. Submissions of original research articles as well as review articles are welcome.

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. 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.
