Special Issue Information
Dear Colleagues,
Gas sensors are applied as an important cornerstone of the digital sensing layer for the Internet of Things, and the innovation of sensitive materials, sensing devices, and sensing mechanisms is of great scientific value in improving gas sensing performance. For the development of novel gas sensing materials, several key scientific issues should be addressed: the structure–activity relationship between gas adsorption/desorption at the gas–solid interface, charge separation and transportation, and gas sensing performance are unclear, and the active sites and gas sensing mechanisms should also be clarified. In recent years, there have been several new strategies to improve the gas sensing performance of nanomaterials, such as reversible tautomerism of the covalent organic framework, the confinement effect of the core-shell nanostructure, micro/nanostructure regulation, hetero-nanostructure construction, the quantum effect for quantum dots/single atom-based gas sensing, defect engineering of the nanostructure, and so on. In addition, in situ characterization techniques and theoretical modeling also provide new insights into gas sensing mechanisms, which have clarified the basic principles of intrinsic gas sensing processes. This research topic collection solicits the latest advances in gas sensing, from fundamentals to application. All studies should put forward new insights into the dynamic process of gas sensing.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.
