Scope

Aims, scope and focus

Gels is published by MDPI and is in Zone 2 of Chemistry in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Hydrogels: synthesis, properties, applications, 3D Printing in Biomedical Research and Electrospun Nanofibers in Biomedical Applications, together about 31.2% of its articles. (generated from OpenAlex topic counts and CAS ranking data)

AimsThe journal Gels (ISSN 2310-2861) is an international, open access journal on physical (supramolecular) and chemical gel-based materials. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the maximum length of the papers, and full experimental details must be provided so that the results can be reproduced. Short communications, full research papers and review papers are accepted formats for the preparation of the manuscripts.Gels aims to serve as a reference journal with a focus on gel materials for researchers working in both academia and industry. Therefore, papers demonstrating practical applications of these materials are particularly welcome. Occasionally, invited contributions (i.e., original research and review articles) on emerging issues and high-tech applications of gels are published as special issues.ScopeGeneral subject areas include: Organogels, hydrogels and ionic gels made either from low molecular weight compounds and/or polymers (i.e., physical (supramolecular) and chemical gels); Composite and hybrid materials where a metal is by some means incorporated into the gel network (i.e., metallogels); Dried-gels; Colloidal gels; Gels made in mixtures of solvents; Computational modeling of these materials in order to provide a better understanding of gelation mechanism; Synthesis, characterization and applications of the above-mentioned materials Gels as raw materials for the synthesis of non-gel functional materials MDPI Publication Ethics Statement MDPI is a member of the Committee on Publication Ethics (COPE). MDPI takes the responsibility to enforce a rigorous peer-review together with strict ethical policies and standards to ensure to add high quality scientific works to the field of scholarly publication. Unfortunately, cases of plagiarism, data falsification, inappropriate authorship credit, and the like, do arise. MDPI takes such publishing ethics issues very seriously and our editors are trained to proceed in such cases with a zero tolerance policy. To verify the originality of content submitted to our journals, we use iThenticate to check submissions against previous publications.Book ReviewsAuthors and publishers are encouraged to send review copies of their recent related books to the following address. Received books will be listed as Books Received within the journal's News & Announcements section. MDPI Grosspeteranlage 5
