Structural, optical and magnetic properties of Fe3O4 nanoparticles prepared by a facile microwave combustion method

TL;DR: In this article, a facile microwave combustion method was used to synthesize Fe3O4 nanoparticles by using X-ray diffraction and energy dispersive Xray spectroscopy results showed that the as-prepared product was pure Fe 3O4 without any impurity.
Journal ArticleDOI

Green-fuel-mediated synthesis of self-assembled NiO nano-sticks for dual applications—photocatalytic activity on Rose Bengal dye and antimicrobial action on bacterial strains

TL;DR: In this paper, a 100% green-fuel-mediated hot-plate combustion reaction was used to synthesize self-assembled NiO nano-sticks with superior photocatalytic activity on Rose Bengal dye and superior antibacterial potential towards both Grampositive and Gram-negative bacteria.
Journal ArticleDOI

Catalytic studies of NiFe2O4 nanoparticles prepared by conventional and microwave combustion method

TL;DR: A simple and rapid synthesis has been developed to synthesize NiFe2O4 nanoparticles with tunable optical, magnetic and catalytic properties by using Hibiscus rosa sinensis plant extract in the current study as discussed by the authors.
Journal ArticleDOI

Structural, optical and room-temperature ferromagnetic properties of Fe-doped CuO nanostructures

TL;DR: In this article, X-ray diffraction (XRD), high resolution scanning electron microscopy (HR-SEM), diffuse reflectance spectroscopy (DRS), photoluminescence (PL) and vibrating sample magnetometry (VSM) measurements were characterized by XRD patterns refined by the Rietveld method and also confirmed that Fe ions successfully incorporated into CuO crystal lattice by occupying Cu ionic sites.
Journal ArticleDOI

Comparative investigation of NiO nano- and microstructures for structural, optical and magnetic properties

TL;DR: In this paper, the formation of cubic phase NiO nano-and microstructures were confirmed by X-ray powder diffraction (XRD), high resolution scanning electron microscopy (HR-SEM), high-resolution transmission electron microscope (H-TEM), energy dispersive Xray analysis (EDX), diffuse reflectance spectroscopy (DRS), photoluminescence (PL), Brunauer-Emmett-Teller (BET) analysis and vibrating sample magnetometer (VSM) analysis.
