The development of metal-oxide semiconductor (MOS) based gas sensor has engrossed
demanding research interest in the last several decades because of their potential for the …

We have investigated the interactions between a 5-aminolevulinic acid (ALA) drug and ZnO
nanostructures including ZnO monolayers and ZnO nanotubes (ZnONTs) using density …

Micro-electromechanical system (MEMS) gas sensors represent a system that is capable of
detecting the existence and concentration of gasses in the atmosphere. These sensors have …

Pure, mixed and doped metal oxides (MOX) have attracted great interest for the
development of electrical and electrochemical sensors since they are cheaper, faster, easier …

With the increasing popularity of battery technology, the safety problems caused by the
thermal runaway of batteries have been paid more attention. Detecting the gases released …

Experimental work has already demonstrated that Al-doped ZnO nanostructures exhibit a
higher response than the pure ZnO sample to CO gas and can detect it at sub-ppm …

Herein, we report the synthesis, characterization, and gas sensing applications of Pt
nanoparticles-decorated SnO 2 nanoneedles synthesized through a facile hydrothermal …

Vertically oriented zinc oxide (ZnO) nanomaterials, such as nanorods (NRs), nanowires
(NWs), nanotubes (NTs), nanoneedles (NNs), and nanosheets (NSs), are highly ordered …
