Advanced Materials for Gas Sensors: Performance and Application

Dear Colleagues,

Gas sensors, despite being the subject of research for many years, are still attracting significant attention from the scientific community due to their numerous applications. Indeed, they have become essential in several fields, including environmental monitoring and worker safety, medical care, food quality tracking and industrial processes. Furthermore, gas sensors could play an important role in the Internet of Things (IoT) field, not only from the perspective of smart cities, industries, or homes, but also in wearable health monitoring devices.

For all these applications, market requests are becoming increasingly demanding, especially in terms of detection limit, response and recovery time and sensitivity to low ppm concentration among interfering gases, not to mention cost and energy consumption.

One strategy to address these requirements is the search for new suitable materials, as well as novel functionalization strategies and innovative fabrication processes, which can enhance the sensor performance.

Therefore, the goal of the present Special Issue is to present novel and promising experimental and theoretical approaches in gas sensor and sensor array development exploiting advanced materials. The latest advances in science and technology will be highlighted, including novel high-performance materials with enhanced sensing properties, innovative functionalization techniques and cutting-edge fabrication and processing methods. Works investigating the sensing mechanisms through innovative techniques and from a theoretical point of view are also welcome.

Original research articles (full papers or communications) and reviews are all welcome.

I look forward to receiving your contributions.

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. Materials 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 2600 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.
