Nanostructured GaN and AlGaN/GaN heterostructure for ...

Jul 01, 2019· Inadequate research on the development of catalyst-free room-temperature CO sensing using GaN based structures is the critical reason behind the subjugation of this area. Therefore, in the present article, we aimed the development of GaN & AlGaN/GaN heterostructure based gas sensors for catalyst-free low-temperature CO sensing (at 100 ppm).

Graphene-based CO 2 sensing and its cross-sensitivity with ...

We present graphene-based CO 2 sensing and analyze its cross-sensitivity with humidity. In order to assess the selectivity of graphene-based gas sensing to various gases, measurements are performed in argon (Ar), nitrogen (N 2), oxygen (O 2), carbon dioxide (CO 2), and air by selectively venting the desired gas from compressed gas bottles into an evacuated vacuum chamber.

The CO sensing properties of a micro thermoelectric gas sensor (micro-TGS) with a double AuPtPd/SnO2 and Pt/α-Al2O3 catalyst were investigated. While several nanometer sized Pt and Pd particles were uniformly dispersed on SnO2, the Au particles were aggregated as particles measuring >10 nm in diameter. In situ diffuse reflectance Fourier transform Infrared spectroscopy (DRIFT) …

SnO2/Au multilayer heterostructure for efficient CO sensing

Apr 01, 2020· Apr 01, 2020· The sensing behavior of the samples for CO gas was tested and the variation of the current with time for all 4 samples during sensing is shown in Fig. 6. An increment in the current (decrement in resistance) is observed when the films are exposed to CO gas which reverses as soon as the gas flow to the sample is stopped.

Sparse Sensing With Co-Prime Samplers and Arrays ...

This paper considers the sampling of temporal or spatial wide sense stationary (WSS) signals using a co-prime pair of sparse samplers. Several properties and applications of co-prime samplers are developed. First, for uniform spatial sampling with M and N sensors where M and N are co-prime with appropriate interelement spacings, the difference co-array has O(MN) freedoms which can be exploited ...
