Characterization of H2S gas sensor based on CuFe2O4nanoparticles
( Elsevier Ltd , 2017 , Article)Copper ferrite (CuFe2O4) nanoparticles were prepared by the sol-gel auto-combustion method and used to construct a conductometric gas sensor in this work. The as-prepared CuFe2O4 nanoparticles were annealed at 500 °C and ... -
Effect of Zn and Ni substitution on structural, morphological and magnetic properties of tin oxide nanoparticles
( Elsevier , 2016 , Article)Structural, morphological, optical and magnetic properties of Zn and Zn–Ni co-doped tin oxide (SnO2) nanoparticles synthesized by sol-gel method. The influence of doping concentration on phase and particle size of the ... -
Fabrication of H2S gas sensors using ZnxCu1-xFe2O4 nanoparticles
( Springer , 2020 , Article)Spinel ferrite nanoparticles can be easily retrieved and utilized for multiple cycles due to their magnetic properties. In this work, nanoparticles of a ZnxCu1-xFe2O4 composition were synthesized by employing a sol–gel ... -
Selective H2S sensor based on CuO nanoparticles embedded in organic membranes
( Elsevier B.V. , 2016 , Article)We report on H2S gas sensors based on CuO nanoparticles that are embedded within polymer membranes of poly-vinyl-alcohol (PVA) and glycerol ionic liquid (IL). The nanoparticles were fabricated by the colloid microwave ... -
Simulation of natural convective heat transfer and entropy generation of nanoparticles around two spheres in horizontal arrangement
( Elsevier , 2021 , Article)Herein, laminar convective heat transfer from two horizontally arranged spheres has been evaluated by using numerical models inside water-based fluids incorporated with alumina (Al2O3), copper oxide (CuO), and copper (Cu) ...
