This paper focused on the preparation of pure and Cr-doped tungsten trioxide (WO3) thin
films using the spray pyrolysis method. Different techniques were adopted to analyze these …

A novel electrochemical sensor on ZIF‐8 nanocomposites (Ag/ZnO/ZIF‐8) was developed to
analyze the mercury ions (Hg2+). The ZIF‐8 materials are one of the 3‐dimensional porous …

A room temperature gas sensor with excellent stability and a high response has gotten a lot
of interest, and there is a huge demand for them. Therefore, NH3 identification is crucial for …

Abstract CdO, ZnO, and CdZnO thin films were deposited using the nebulizer spray pyrolysis
method, and their properties were investigated for gas sensing applications. The deposition …

In this contribution, pure, polycrystalline wurtzite crystal structured, spin-coated pristine ZnO
and Ti-doped (1, 2, and 3 wt%) ZnO transparent films were accomplished at 400° C through …

Highly selective, sensitive, and reliable sensing techniques for ammonia gas detection have
been in high demand in recent years. Therefore, NH3 identification is crucial for life-saving …

The current work delivers room-temperature ammonia (NH3) gas-detectable pristine, Nb-
doped TiO2 air-and vacuum-annealed films obtained through the solution-combustion …
