Plasma-enhanced atomic layer deposition (PEALD) is well-known for fabricating conformal and uniform films with a well-controlled thickness at the atomic level over any type of supporting substrate. We prepared nickel oxide (NiO) thin films via PEALD using bis(ethylcyclopentadienyl)-nickel (Ni(EtCp)2) and O2 plasma. To optimize the PEALD process, th...
A facile template-free synthesis strategy is demonstrated to fabricate nanostructured NiO/N-doped graphene hybrid, in which NiO hollow nanospheres with hierarchically mesoporous structure are tightly anchored on N-doped graphene matrix. The mesoporous shell of NiO can not only provide sufficient electrode/electrolyte contact areas to accelerate io...

Carbon/nickel nanocomposites were prepared using the sol–gel method after the incorporation of nickel oxide (NiO) nanoparticles with different mass ratio between 2 and 10% in organic matrix based on pyrogallol–formaldehyde (PF). The obtained materials (C/Ni) were the subjected of heat treatment under inert atmosphere at 650 °C during 2 h. The X-ray...
L’électrochromisme se définit par la capacité d’un système à modifier ses propriétés optiques en réponse à une tension électrique. Aujourd’hui, les vitrages intelligents sont une des applications phare. Ce manuscrit contribue à une meilleure compréhension du mécanisme responsable de la commutation optique du matériau à coloration anodique NiO. Des ...

Nanostructured nickel oxide (NiO) electrode has been prepared using electrochemical work station operated on galvanostatic mode in supercapacitor application. Crystalline cubic structure and nanoplate-type of morphology of synthesized NiO electrode was confirmed from X-ray diffraction and scanning electron microscopy analysis respectively. The wett...

Nickel oxide (NiO) nanotubes were fabricated by coaxial electrospinning technique combining a calcination process. The nanotubes obtained have diameters of 140–240 nm, and wall thickness of 50–70 nm. The crystallinity, morphology and structure features of the NiO nanotubes were investigated by powder X-ray diffraction, field-emission scanning elect...

Nickel oxide (NiO) nanoparticles were synthesised by nanosecond laser ablation in deionised water. Spherical NiO nanoparticles with sizes ranging from 2 to 21 nm were produced. The optical absorption spectra of the nanoparticles were measured using UV–VIS spectroscopy, and their size distribution was characterised using transmission electron micros...

NiO nanosheets are prepared by calcination of nickel hydroxide nanosheets, obtained by the hydrolysis of trans-bis(acetato-κO)bis(2-aminoethanol-κ2N,O)nickel(II) complex. BET analysis reveals the presence of a high specific surface area of 48 m2g−1 and a pore volume of 0.26 cm3g−1 after calcination at 400 °C. The two-dimensional NiO nanostructure u...

Widespread use of X-band frequency (a part of the super high frequency microwave) in the various workplaces would contribute to occupational exposure with potential of adverse health effects. According to limited study on microwave shielding for the workplace, this study tried to prepare a new microwave shielding for this purpose. We used EI-403 ep...
