Recent Progress on Sensors and Smart Systems for In-Situ Gas Monitoring

Dear Colleagues,

The recognized impacts of air pollution on the environment and on human health  prompted extensive research to determine safe limits for the emission and exposure to known airborne hazardous substances. As a result, the number of applications needing in situ and real-time detection of a wide range of gases has increased dramatically.

The research and development of sensors and smart systems are critical for the reliable monitoring of gases, meeting the requirements of high sensitivity, precise discrimination at a variety of testing conditions, and long-term stability. The advances in this research field include the study of new functional materials, well-suited design and miniaturization of sensing devices and systems, innovative methods for activating the receptor unit, such as UV–visible light, chemometrics, and so on. Moreover, new experimental approaches, both in situ and operando, investigate the interaction between the analytes and the sensing units to uncover the mechanism of detection for the fine tuning of sensor properties for specific applications.

This Special Issue seeks original research papers as well as review articles, with an emphasis on theoretical and experimental studies regarding sensors and systems for reliable in situ and continuous gas monitoring. The themes covered include, but are not limited to, the following:

• Nanostructured 1D, 2D and 3D materials for gas sensors;
• Metal-oxides and MOF-based gas sensors;
• Photoactivated gas sensing materials;
• Sensors arrays;
• Miniaturized gas sensors and olfactory systems;
• Simulation of gas sensing and smart systems;
• Sensors application for IoT;
• Chemometrics;
• In situ and operando characterizations of gas sensors.

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. Chemosensors 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 2700 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.
