The present review concerns thin film field effect transistor (TFT)-based gas sensors with
special emphasis on material synthesis, electrical characterizations and sensing properties …

In this paper, we present H2 gas sensors based on hollow and filled, well-aligned
electrospun SnO2 nanofibers, operating at a low temperature of 150° C. SnO2 nanofibers …

A highly sensitive and selective gas-sensing material based on gold (Au)-functionalized
tungsten oxide (WO 3) composite nanofibers (NFs) has been fabricated under mild …

Single crystalline WO 3 nanowires were directly grown on FTO substrates by a hydrothermal
approach. After calcination at 400° C, the nanowires assumed an orthorhombic structure …

We report on ethanol (C2H5OH) vapour sensing devices based on nanostructured cupric
oxide (CuO) and cuprous oxide (Cu2O) thin films, which are deposited using RF sputtering …

A tungsten disulfide/tungsten trioxide (WS 2/WO 3) based ethanol sensor was fabricated by
layer-by-layer self-assembly technique, which was deposited on a substrate with interdigital …

Theophylline (TP) is a methylxanthine derivative, which serves as a valuable compound in
treating respiratory disorders and acts as a bronchodilator agent. However, TP has a limited …

Attributing to their distinct thickness and surface dependent physicochemical properties, two
dimensional (2D) nanostructures have become an area of increasing interest for interfacial …

Alignment of nanowires over a large area of flat and patterned substrates is a prerequisite to
use their collective properties in devices such as gas sensors. In this work, uniform single …

This paper reports the development of nanoporous tungsten trioxide (WO3) Schottky diode-
based gas sensors. Nanoporous WO3 films were prepared by anodic oxidation of tungsten …
