Nanostructured gas sensors in smart manufacturing
(2021-01-01)
Gas sensors are used for measuring the concentration of pressure of gases around their vicinity. These sensors are equipped with highly sensitive sensing elements of nanostructured materials. They find extensive application ...
Gas sensor for ammonia detection based on poly(vinyl alcohol) and polyaniline electrospun
(Wiley-Blackwell, 2019-04-05)
In this article, the results of the process and fabrication of ammonia gas sensors are obtained through the production of poly(vinyl alcohol) and polyaniline (PVA/PANI) nanofibers in different concentrations deposited on ...
Gas sensor properties of zno nanorods grown by chemical bath deposition
(2014)
The present work shows a study about the growing of ZnO nanorods by chemical bath deposition (CBD) and its application as gas sensor. It was prepared ZnO nanorods and Au decorated ZnO nanorods and the samples were characterized ...
The role of hierarchical morphologies in the superior gas sensing performance of CuO-based chemiresistors
(2013-04-12)
The development of gas sensors with innovative designs and advanced functional materials has attracted considerable scientific interest given their potential for addressing important technological challenges. This work ...
Giant Chemo-Resistance of SnO disk-like structures
(2013-07-03)
Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
