With a rising emphasis on public safety and quality of life, there is an urgent need to ensure
optimal air quality, both indoors and outdoors. Detecting toxic gaseous compounds plays a …

Low-cost and high-performance UV photodetector (PD) based on anatase titanium dioxide
(TiO 2) and nitrogen-doped graphene quantum dots (N-GQDs) bilayer heterojunction were …

The urgency of early lung cancer (LC) diagnosis and treatment has been more and more
significant. Exhaled breath analysis using gas sensors is a promising way to find out if …

Here, we demonstrate an improvement in sensitivity toward the NO2 analyte by varying the
width ratio of adjacent graphene oxide (GO) and reduced graphene oxide (rGO) layers using …

Assembling a heterojunction-based composite nanomaterial to simultaneously achieve
higher response and superior selectivity towards NO 2 under room-temperature conditions …

In this paper, the SnO 2 and Ce/SnO 2 nanomaterials are synthesized through a simple
hydrothermal route and used for detecting NO 2 gas. The SnO 2 materials exhibit a good …

Chemiresistive gas sensing has attracted extensive research attention in recent years, and
the facile low-cost synthesis of sensitive materials is important for realizing practical use …

Herein, we report a simple, low-temperature, ecofriendly synthesis of graphene oxide
nanosheets (GONs). Graphite powder was treated with KMnO 4 and a concentrated H 2 SO …

The increasing demand to mitigate the alarming effects of the emission of ammonia (NH3)
on human health and the environment has highlighted the growing attention to the design of …
