Structural and gas-sensing properties of CuO–CuxFe3−xO4 nanostructured thin films [PDF]
, 2010 Nanocrystalline CuO–CuxFe3−xO4 thin films were developed using a radio-frequency sputtering method followed by a thermal oxidation process. Thin films were deposited applying two very different conditions by varying the argon pressure and the target-to ...

Photoacoustic-Based Gas Sensing: A Review [PDF]
Sensors, 2020 The use of the photoacoustic effect to gauge the concentration of gases is an attractive alternative in the realm of optical detection methods. Even though the effect has been applied for gas sensing for almost a century, its potential for ultra-sensitive and miniaturized devices is still not fully explored.

Simulation of gas sensing with a triboelectric nanogenerator [PDF]
Beilstein Journal of Nanotechnology, 2021 Safety concerns require the frequently check for leaks in gas pipelines. Also, in coal mines the type gases permeating from the ground need to be monitored. Triboelectric nanogenerators (TENGs) can be applied for gas sensing without external power supply.
