Gels for Removal and Adsorption

Dear Colleagues,

Gels (aerogels, hydrogels, etc.), which are typically constructed in the forms of sponges, membranes, films, rods, fibers, etc., hold huge potential in the adsorption and removal of substances because of their abundant and tunable porous structure, lightweight properties, and programmable surface groups, which are beneficial to specifically and efficiently capture targeted substances.

This Special Issue is focused on the application of gels for adsorption and removal. The targeted substances include but are not limited to gaseous, liquid, and solid states. The gaseous matters can be poisonous gases (e.g., SO_x, NO_x, and CO), greenhouse gases (e.g., CO₂, freon, and CH₄), etc. The liquid matters include wastewaters containing oils, heavy metal ions, radioactive materials, dyes, and antibiotics. The targeted solids are represented by a variety of particulates (e.g., haze, dust, microorganisms). This Special Issue also welcomes research on the adsorption and removal of other special states of matter, such as plasmas, supercritical materials, liquid crystals, and superconductive materials. Therefore, the collected articles should not only focus on the preparation and characterizations of gels, but also their adsorption and removal properties. More importantly, the adsorption and removal mechanisms of gels, especially structure-activity relationships, should also be highlighted. This Special Issue also covers gels for the absorption and controlled release of drugs in postoperative repair dressing and wound healing. For these applications, the gels have to be constructed responsively or intelligently geared towards certain environmental stimulation, such as pH, light, magnetic field, electric field, and temperature for controlled drug release. The publication of original research articles, rapid communications and reviews in this Special Issue will make an important contribution to developing gels for removal and adsorption.

We look forward to the submission of new studies on gel development and application for adsorption and removal. Submissions of experimental and field studies are both welcomed.

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. 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.
