Gas sensors allow the monitoring of the chemical environment of humans, which is often
crucial for their wellbeing or even survival. Miniaturization, reversibility, and selectivity are …

Heating plays a vital role in science, engineering, mining, and space, where heating can be
achieved via electrical, induction, infrared, or microwave radiation. For fast switching and …

Hollow In2O3@ TiO2 double-layer nanospheres were prepared via a facile water bath
method using the sacrifice template of carbon nanospheres. It is shown that the size of the …

Abstract Electrochemical Impedance Spectroscopy (EIS) in the past few years has been
used to design gas sensors. EIS based gas sensing has been considered as an ultra …

Two-dimensional nanomaterials (2DNMs) have attracted significant research interest due to
their outstanding structural properties, which include unique electrical nanostructures, large …

Facile hydrothermal route was employed to prepare MoS 2 nanoparticles (NPs) on the glass
substrates at low temperature. MoS 2 NPs were crystallized into hexagonal lattice. The MoS …

In this study, we prepared Rb-doped ZnO/In 2 O 3 nn nano-heterojunction, which functioned
as highly responsive gas sensors for NO 2 at room temperature. The experiments …

Approaches are being developed to create composite materials with a fractal-percolation
structure based on intercalated porous matrices to increase the sensitivity of adsorption gas …

In this study, zinc oxide nanoparticles (ZnO NPs) were synthesized using an aqueous extract
of the Ocimum lamifolium (O. lamifolium) plant. The I-optimal coordinate exchange …

Nanoscale heterostructured zinc oxide/reduced graphene oxide (ZnO/rGO) materials with p–
n heterojunctions exhibit excellent low temperature NO2 gas sensing performance, but their …
