Special Issue Information
Dear Colleagues,
Silica aerogel is a highly porous and lightweight material known for its exceptional thermal insulation and unique properties. The synthesis of silica aerogel typically involves sol-gel techniques, where silica particles are formed in a liquid solution and subsequently transformed into a gel state. This gel undergoes supercritical drying to remove the liquid component without collapsing the structure, resulting in an aerogel.
The properties of silica aerogel include low density, high specific surface area, and low thermal conductivity, making it an ideal candidate for various applications, ranging from insulation in buildings and aerospace to drug delivery systems and environmental remediation. The characterization of silica aerogel involves various techniques such as scanning electron microscopy (SEM) and nitrogen adsorption-desorption isotherms, which help in understanding its microstructure and porosity.
Overall, silica aerogel is a versatile material that is continuously being explored for innovative uses in numerous fields due to its unique combination of properties and performance characteristics. As research progresses, advancements in synthesis methods and material formulations are likely to enhance its applicability and functionality in real-world applications. I am thrilled to invite you, as renowned experts in the field, to contribute to this Special Issue and the development of the scientific study of silica aerogel.

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.
