Efficient humidity-sensitive electrical response of annealed lithium substituted nickel ferrite (Li–NiFe2O4) nanoparticles under ideal, real and corrosive environments

Role of Ruthenium in the Dielectric, Magnetic Properties of Nickel Ferrite (Ru–NiFe2O4) Nanoparticles and Their Application in Hydrogen Sensors

“…At higher annealing temperatures, iron ions could distribute evenly with secondary phases, warranting the formation of the Ru–NiFe 2 O 4 . The grain sizes were estimated on the (311) diffraction peak using the Scherrer equation . On air-annealing, the grain-size increases from 3 to −48 nm, suggesting stimulation of the nucleation and growth, which eventually increases the size .…”

“…28 The grain sizes were estimated on the (311) diffraction peak using the Scherrer equation. 29 On air-annealing, the grain-size increases from 3 to −48 nm, suggesting stimulation of the nucleation and growth, which eventually increases the size. 30 The concerned XRD parameters are listed in Table 1.…”

A reliable chemiresistive sensor of nickel-doped tin oxide (Ni-SnO2) for sensing carbon dioxide gas and humidity

“…These results suggest that nickel ions can be doped into the tin lattice without structural deviation. 34,35 Fig. 5a-c display the FTIR transmittance spectra of Ni-SnO 2 NPs containing different concentrations of nickel.…”

Facile Fabrication of Au Nanoparticles/Tin Oxide/Reduced Graphene Oxide Ternary Nanocomposite and Its High-Performance SF6 Decomposition Components Sensing

“…When the sensor was in contact with the incoming gas, the change in resistance throughout the process was recorded by the electrochemical workstation. Due to the corrosive nature of the SF 6 decomposition components, there may be some changes in sensor parameters after prolonged exposure to these gases (Petrila et al, 2016; Bansode et al, 2017; Manikandan et al, 2018); however, the effects of such variations will not be discussed in this study. The gas flow rate was controlled to 500 ml/min.…”
