Special Issue Information

Dear Colleagues,

In recent decades, gas sensors have triggered the attention of many researchers and scientists, owing to their widespread application in different fields, for example, environmental monitoring, automotive production, chemical and pharmaceutical industries, medical diagnosis, etc. They are well-known by their small size, low cost, easy manufacture and a wide spectrum of detectable gases. With the emergence of nanotechnologies, nanomaterials (compounds with at least one external dimension between 1 nm and 100 nm) have become suitable candidates for gas sensing applications. They possess unique physical and chemical properties (such as high surface-to-volume ratio, quantum confinement effects, etc.) that promote sensor performances (stability, sensitivity, selectivity). Among these nanomaterials, we can cite metal oxide nanomaterials, which are characterized by their reliability in detecting various toxic gases with enough sensitivity and good reproducibility. However, they also suffer from some drawbacks that influence their usability, such as lack of selectivity and high working temperature. These shortcomings have opened various pathways of innovative research—e.g., metal/metal oxides functionalization, nanocomposites and so forth. Transition metal dichalcogenide (TMD) nanomaterials have also sparked the interest of scientists in the field of gas sensors, especially in the development of high-performance room-temperature sensors for detection of toxic gases at very low levels. They consist of metal atomic layers (such as Mo, W, Hf, Ti, Zr, V, Nb, Ta, Re, etc.) between two chalcogen atomic layers (S, Se or Te), and then these multiple trilayers are stacked on top of one another by van der Waals interactions. They have a direct band gap and large specific surface area due to sheet-like structures, thus bestowing the sensors with improved sensitivity, selectivity and low power consumption. This Special Issue will highlight the recent developments in gas sensors based either on metal oxides or transition metal dichalcogenides nanomaterials that show promising results in terms of sensitivity, selectivity, humidity cross sensitivity and low temperature detection.

Manuscripts can be submitted until the deadline. All papers will be 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. Sensors 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 2200 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.
