Gas Sensors: Materials and Design

Dear Colleagues,

Pollution, including air contamination, is one of the major issues currently faced by the humankind. The main cause of air pollution is the release of domestic and industrial pollutants which are harmful to human health and the planet. Therefore, efficient sensors are needed to detect pollutants. The research and development in the field of gas sensors started a long time ago, and various materials have been explored for sensing toxic gases and pollutants. Today, the sensors are in the market, developed by academic institutions and industries. However, there is plenty of space to develop and fabricate efficient gas sensors that are likely to be utilized for indoor to outdoor air quality monitoring. These sensors could be used for various fields such as breath analysis, household and industrial safety, detection of toxicants, explosives and weapons, and many more. Moreover, for the early detection of diseases, it could be a time-saving diagnostic tool, and for the Internet of Things, it could smell as well as humans do.   

As an expert in the sensing field, you are invited to submit your contributions in the field of gas sensors covering basic principles, sensing phenomena, development of sensor materials, sensing strategies and fabrication of sensors. Contributions from industries would also be appreciated. This Special Issue is open for all materials used to sense various gases including O₂, H₂, COx, NOx, NH₃, LPG, H₂S, CH₄, SO_x, organic contaminations, etc.

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. Micromachines 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 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.
