Gas sensors based on SnO 2 nanostructures have been extensively investigated in recent
years. Many recent investigations have focused on synthesizing 0D, 1D, 2D and 3D SnO 2 …

Highly sensitive semiconductor gas sensors hold great potential for applications in trace gas
detection. Reliable detection of ppb-level NO2 is crucial for environmental monitoring, which …

In this work, pure and 2% rare earth elements RE (RE= Y and Gd) doped NiO nanoparticles,
capped with polyvinyl alcohol PVA, were prepared by coprecipitation technique. X-ray …

The effect of Radio Frequency (RF) power on the properties of magnetron sputtered Al
doped ZnO thin films and the related sensor properties are investigated. A series of 2 wt% Al …

A new biopolymer based ZnO-PVP nanocomposite was successfully synthesized by single
step in situ precipitation method using chitosan as biosurfactant, zinc chloride as a source …

Zinc oxide (ZnO) is one of the most promising semiconducting metal oxides, particularly for
gas sensing applications. Impurity doped ZnO has offered much improved sensing …

Abstract Hematite (α-Fe 2 O 3) nanorods with an average diameter of 40 nm were prepared
using a template-free sol–gel method. These nanorods then mixed with polyvinyl alcohol …

This paper describes the fabrication of a four element gas sensor array for monitoring air
pollutants, namely CO, CO 2, NO 2, and SO 2. The four micro-heaters share a single …

Un-doped and Y doped ZnO thin films were deposited successfully by sol–gel spin coating
method with different Y concentrations. The X-ray diffraction spectra revealed that all the …

In the present study, zinc oxide doped nickel thin films (ZnO: Ni) at different percentage (1–
3%) were deposited on glass substrates using a chemical spray technique. The effect of Ni …
