Applications of Gels in Energy Materials and Devices (2nd Edition)

Dear Colleagues,

Gels are solid three-dimensional networks that entrap a liquid medium through surface tension. Different types of gels range from soft and weak to hard and robust. Some gels form when two or more substances are mixed during heating, while others form when a liquid is cooled down to a certain temperature. Their unique properties, such as their ability to hold large quantities of a liquid in a concentrated form and their stability and inertness, have led to their use in various products, from food to cosmetics. Gels are prevalent in pharmaceuticals and environmental and bio-related fields and highly desirable for use in materials and devices that generate, convert, and store energy.

Energy is the lifeblood of industry and drives the wheels of progress in modern society. It is also essential for our daily lives, powering our homes and businesses and providing essential services such as transportation, communications, and health care. Without access to energy, we would be unable to live as we do today. There has been a global surge in interest in energy conversion and storage, driven by the need to reduce our carbon emissions and the demand for renewable energy sources. Companies are investing heavily in researching and developing new technologies, such as batteries, fuel cells, and renewable energy sources.

Notably, gels exhibit impressive properties at the electronic, optoelectronic, and electrochemical levels. They can provide a high surface area while being flexible and lightweight. Gels can also store and release energy when exposed to heat and pressure. These properties make them suitable for use in various applications, such as energy storage, sensors, optoelectronic devices, and fuel cells. The quantity of research in this area is rising, providing an ideal opportunity for a Special Issue focused on these new applications (in electronics and energy capturing, storage, and harvesting) for gels.

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.
