Continuous human activity is to blame for releasing nitrogen dioxide (NO 2), an unhealthy
gas with an acidic nature and a pungent smell, into the atmosphere. The conventional …

NO 2 is one of the recognized six major pollutants worldwide. Its monitoring and forewarning
are indispensable for human health. Thus, a practical sensor with rapid response and high …

Grafted structures between SnO 2 and ZnO nanowires were realized in a two-step process
of growth. First, the rootstocks of SnO 2 or ZnO nanowires were synthesized by thermal …

Tellurium (Te), the most metallic semiconductor, has been widely explored in recent
decades owing to its fantastic properties such as a tunable bandgap, high carrier mobility …

Gas detection and discrimination have been, until recently, sensors-specific, with different
sensors and techniques used for each of the gases. In this work, we describe a novel …

Gas sensing at low temperatures remains a notable challenge at present. Owing to their
strong catalytic activity, oxygen defects, and unique size, pyrochlore-based oxides have …

Specific surface area and oxygen vacancies are considered to be essential factors to
enhance the gas sensitivity properties of sensing materials. Herein, we first synthesized …

The focus of gas sensor research has been on improving the response of individual sensors.
However, in order to integrate sensors with CMOS circuits, a sensing system composed of …

WSe2 has been widely used in NO2 gas sensors in recent years, but it still suffers from low
responsiveness and slow reaction kinetics. Herein, we used the chemical vapor deposition …

Most NO gas sensors are evaluated using continuous NO gas, making it difficult to
accurately recognize discontinuous gas flow. Here, to reveal the response characteristics in …
