Electronic noses (e-noses) are devices based on combining different gas sensors'
responses to a given sample for identifying specific odor fingerprints. In recent years, this …

Abstract Pristine and Al-doped SnO 2 nanoparticles with different amounts of Al dopant were
synthesized using a conventional hydrothermal process. The existing SnO 2 exhibited …

Hydrogen (H 2) is the cleanest energy but also dangerous, thus the real-time detection of H
2 leakage is crucially important. Herein, we develop ultra-large micro-sized Sn 3 O 4 …

It is important to improve the sensitivities and selectivities of metal oxide semiconductor
(MOS) gas sensors when they are used to monitor the state of hydrogen in aerospace …

We investigated the sensitivity and reactivity of open edge zigzag and armchair graphene
slabs toward CO 2 gas, using density functional theory calculations. Different levels of theory …

This article aims to study how to use gas sensor array detection system to realize the remote
contactless identification of drug-producing chemicals in the external environment. The …

This paper reports a study on the enhanced H2 selectivity of SnO2 gas sensors with SiO2 on
the surface of the sensors obtained via chemical vapor deposition using …

In this paper, an online monitoring system based on a SnO 2 gas chromatographic detector
for power transformer condition assessment is developed. For a quantitative analysis of …

First principles calculations are carried out to investigate the reactivities of pure monolayer
MoS 2 nanosheet doped with non-metal elements X (X= B, P, Cl) in the presence of NO. All …

Al doped tin oxide (Al: SnO2) 1 are fabricated onto silicon substrate by easy spray pyrolysis
route. The room temperature current-voltage (I–V) measurements of Ag/Al: SnO 2/n-Si/Au …
