VOC has brought a lot of troubles to human life. They are the main factors that cause smog
and photochemical pollution. SnO 2-based gas sensors have many good qualities, such as …

Optimizing materials and associated structures for detecting various environmental gas
pollutant concentrations has been a major challenge in environmental sensing technology …

There is a great demand to develop high-performance hydrogen sulfide (H2S) sensors,
especially at the trace level for environmental protection, human healthcare, and food …

The portable electronic nose (E-nose) systems are suffering from the limited computing
ability of microcontrollers and can only adopt simple pattern recognition algorithms. The …

Pattern recognition is the core component of the electronic nose (E-nose). Traditional
machine learning algorithms highly rely on the feature data selected manually for model …

Formaldehyde is a common atmospheric pollutant produced in industrial production and
daily life. However, the traditional semiconductor formaldehyde gas sensor cannot work at …

This work presents an electronic nose (EN)-based gas identification and concentration
estimation method for the detection of food spoilage. The response data of sensors were …

Abstract Two-dimensional (2D) transition metal dichalcogenides (TMDs) have received
emerging attention due to their rich active sites, layered structure, and suitable electronic …

Abstract Tungsten disulfide (WS 2) nanosheets (NSs) have become a promising room-
