Special Issue Information

Dear Colleagues,

We are pleased to present this Special Issue of our journal, dedicated to a field that is revolutionizing multiple industries, entitled Gel-Related Materials: Challenges and Opportunities. Gel-based materials have proven essential in areas ranging from biomedicine to tissue engineering, as well as in food science and energy storage technology. However, along with their vast applications come challenges that must be addressed to fully harness their potential.

This Special Issue brings together a selection of articles that explore both the opportunities and challenges inherent in gel-related materials. Through a series of pioneering studies and research, our contributors examine topics such as the optimization of the mechanical properties of hydrogels, the design of ultra-lightweight aerogels for energy applications, and innovations in biocompatible gels for medical use.

We face challenges such as the long-term stability of these materials, their scalability for industrial production, and the need to develop more sustainable synthesis methods. Yet, the opportunities they present are immense. From creating new biomedical devices to developing sustainable solutions for industry, gel-based materials continue to push the boundaries of science and engineering.

We hope this Special Issue serves as a platform to inspire new ideas, foster interdisciplinary collaborations, and open new avenues of research in this fascinating field. Join us on this journey through the challenges and opportunities that define the future of gel-related materials. The submission of both experimental and theoretical studies is 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. Gels is an international peer-reviewed open access monthly 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 2100 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.

Abstract
A set of carrageenans produced in the potassium form and with chemical structures varying from pure iota-carrageenans to nearly pure kappa-carrageenans is submitted to ultrasonication to reduce their molecular masses Mw while maintaining a constant chemical structure and a polydispersity index around 2.

A set of carrageenans produced in the potassium form and with chemical structures varying from pure iota-carrageenans to nearly pure kappa-carrageenans is submitted to ultrasonication to reduce their molecular masses Mw while maintaining a constant chemical structure and a polydispersity index around 2. The kinetics of ultrasound-induced chain scission are found to be slower for polysaccharides richer in kappa-carrageenan disaccharide units. From the elasticity of samples directly gelled in a rheometer at 1 w/v% in 0.1 M potassium chloride, a critical molecular mass Mc is identified as the mass below which no gel can be formed. Mc is found to be smaller for kappa- and kappa-2-carrageenans of the order of 0.13–0.21 MDa. The presence of more sulphated disaccharide units significantly increases Mc up to 0.28 MDa for iota-carrageenan and 0.57 MDa for a highly sulphated hybrid carrageenan. For the set of Mw and carrageenans tested, no plateau in the Mw dependence of the gels’ elasticities is found. Full article
