NO 2 is an oxidizing gas, which is considered to be the most dangerous and most toxic gas
that should be controlled. Because of the advantages of high sensitivity, selectivity, stability …

Due to its explosive, colorless and volatile nature, detection of ethanol is critical in daily life,
industrial production and medical treatment. Metal oxide semiconductors (MOS) gas sensors …

Hepatitis E virus (HEV) causes an acute, self-limiting hepatitis. The disease takes a severe
form in pregnant women, leading to around 30% mortality. Zinc is an essential micronutrient …

Low-operating temperature gas sensor is of great significance in a range of environmental
and health safety. Here, we present the operation and performance of hexagonal prismatic …

It is desirable but challenging to sense toxic nitrogen dioxide (NO 2) for it has become one of
the most prominent air pollutants. Zinc oxide-based gas sensors are known to detect NO 2 …

Understanding the intricate relationship among the gas sensing data produced from different
ZnO morphologies is crucial for optimizing electronic nose (e-nose) performance. In the …

In this work, a novel ZnO NWs based e-nose has been developed and demonstrated
successfully for its ability to discriminate H 2 S and NO 2 test gases. For this, a MS was …

This work has presented gas sensors based on indium tin oxide (ITO) for the detection of
SO2 and NO2. The ITO gas-sensing material was deposited by radio frequency (RF) …

The prevalence of nitrogen dioxide (NO 2) in the atmosphere is causing a steady increase in
air pollution. As such, there is an urgent need to create a sensitive and energy-efficient NO 2 …

Controlling the morphology of W 18 O 49 nanostructures is an effective way to achieve high
NO 2-sensing performance. Herein, we describe the synthesis of W 18 O 49 nanostructures …
