Environmental monitoring through gas sensors is paramount for the safety and security of
industrial workers and for ecological protection. Graphene is among the most promising …

The term graphene was coined using the prefix “graph” taken from graphite and the suffix “-
ene” for the C= C bond, by Boehm et al. in 1986. The synthesis of graphene can be done …

Sensors, capable of detecting trace amounts of gas molecules or volatile organic
compounds (VOCs), are in great demand for environmental monitoring, food safety, health …

Herein, we report a successful synthesis of supramolecularly assembled polyaniline/silver
oxide/graphene oxide composite (PANI/Ag 2 O/GO) for enhanced NO 2 gas sensing …

Implementing sensitive and fast ppb-level formaldehyde sensing at room temperature is still
in extreme demand for practical indoor air quality monitoring. Herein, we developed a visible …

Formaldehyde (HCHO) is a major indoor pollutant that is extremely harmful to human health
even at ppb-level. Meanwhile, ppb-level HCHO is also a potential disease marker in the …

A novel, highly sensitive gas sensing system that uses a graphene-coated quartz tuning fork
(QTF), based on light-induced thermoelastic spectroscopy (LITES) is developed. Graphene …

The response and recovery of a graphene-based sensor for nitrogen dioxide (NO2) sensing
is improved by a combination of two treatments including rapid thermal annealing (RTA) of …

Herein, we present the gas-dependent electrical properties of a reduced graphene oxide
nanocomposite. The reduced graphene oxide (rGO) was synthesized by reducing GO with …

In this study, we report on the fabrication and evaluation of gas sensing performance for 3× 3
graphene pixel array sensors coated with polymers of intrinsic microporosity (PIM-1 and PIM …
