Enhanced magnetic properties of NiO powders by the mechanical activation of aluminothermic reduction of NiO prepared by a ball milling process

NiO–Ti nanocomposites for contact electrification and energy harvesting: experimental and DFT+U studies

“…2(d). 30 The clustered and nonuniform morphology was the collective effect of the structural deformations, increased heating due to exothermic mechanochemical processing, and rich Ni phase formation due to the solid-state reaction. Compositional analysis (Fig.…”

“…The i-FFT pattern in Fig.2(c) shows an interplanar spacing of 0.2443 nm, equivalent to the interplanar spacing of the Ni (111) plane, indicating the abundance of Ni in the NiO-Ni-TiO 2 nanocomposite. A clustered particle morphology could be observed in the FESEM images of the nanocomposite, as presented in Fig.2(d) 30. The clustered and nonuniform morphology was the collective effect of the structural deformations, increased heating due to exothermic mechanochemical processing, and rich Ni phase formation due to the solidstate reaction.…”

Facile synthesis and characterization of metal ions (Ce, Cu, Gd, Mn and Y) doped Nickel Oxide nanostructures for spintronic and photodiode applications

“…Indeed, the magnetic properties shows a high dependency to the amendment of size and surface morphology. The good control of the nanoparticles form and shape remains so far a challenging task for researchers [12,13]. Earlier, an attempt has been made to eradicate this challenging task, NiO nanoparticles converted into multiphase nanocomposites with varied valent impurities.…”
