NiO nanoparticles and their nanohybrid with flat rGO sheets: As an ideal electroactive material for hybrid capacitor applications

Sabeera Rafiq et al.

Summary: Extensive research has shown that the performance of electrochemical capacitors (ECC) is largely controlled by the nature, structure, surface area, and conductivity of the electrode material. In this study, NiO nanoparticles were prepared using a surfactant-assisted wet-chemical technique and mixed with 2% and 4% rGO for ECC applications. The NiO@rGO nanohybrid exhibited improved surface area, conductivity, and specific capacity, making it suitable for ECC applications. The nanohybrid electrode with 4% graphene content showed high specific capacity and superior rate capability, as well as outstanding cyclic stability. The excellent electrochemical performance was attributed to the good conductivity, large number of active sites, and facile electrolyte diffusion enabled by the well-organized nanostructured constituents.

Comparative investigation of physicochemical properties of cadmium oxide nanoparticles

Alaa Munshi et al.

Summary: CdO nanoparticles were synthesized using urea-assisted auto-combustion and microwave combustion methods, and their properties were investigated after heat treatment at 350 degrees C. The study found that the annealing process and synthesis method significantly affected the phase, crystallite size, and energy band gaps of CdO NPs. The surface morphology and thermal characteristics of the annealed CdO NPs were also examined using SEM and TG-DTA, respectively.

Murraya koenigii mediated synthesis of cobalt doped NiO nanoparticles: Evaluation of structural, optical properties and anti-bacterial activity

Nuha Y. Elamin et al.

Summary: Recently, there has been a global focus on the synthesis of nanoparticles using phytoextracts which have reduced chemical toxicity. In this study, NiO and Co-doped NiO nanoparticles were successfully prepared using Murraya Koenigii leaf extracts as a replacement for synthetic bactericides. The prepared samples were characterized using various analytical techniques and exhibited crystalline cubic structure. The Co-doped NiO nanoparticles showed enhanced antibacterial activity against both gram negative and gram positive bacterial strains.

Electrical resistivity and magnetic susceptibility of substoichiometric CdO and In doped CdO films

M. A. Awad et al.

Summary: Undoped and In-doped substoichiometric CdO nanostructured films were prepared via vapor transport method, with undoped CdO sample showing net-like assemblies of nanowires and In-doped CdO sample displaying a regular morphology of equally shaped grains. The room temperature electrical resistivity values were found to be 1.56 x 10(2) and 2.31 x 10(-2) omega cm for undoped and In-doped CdO films, respectively. Temperature dependent resistivity measurements revealed semiconducting behavior for undoped CdO films and a semiconductor-metal transition around 367 K for In-doped CdO film, while magnetic susceptibility showed paramagnetic-antiferromagnetic transitions with Néel temperatures of 266 and 308 K for undoped and In-doped CdO samples, respectively.
