in the present work, we report the synthesis of binary nano metal oxides such as zinc /copper oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. the synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦c. x...

In this work, copper oxide nanoparticles have been synthesized via extractive Rosmarinus Officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (CH3COO)2Cu+H2O individually as Cu sources. It was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0C. Powder X-ray Diffrac...

Objective(s):Iron oxide nanoparticles have found prevalent applications in various fields including drug delivery, cell separation and as contrast agents. Super paramagnetic iron oxide (SPIO) nanoparticles allow researchers and clinicians to enhance the tissue contrast of an area of interest by increasing the relaxation rate of water. In this study, we evaluate the dependency of hydrodynamic si...

zinc oxide (zno) nanopowders were synthesized by the sol–gel method from an ethanol solution of zinc sulfate heptahydrate in the presence of diethylene glycol surfactant. detailed structural and microstructural investigations were carried out using x-ray diffraction (xrd), high-resolution transmission electron microscopy (hrtem), field emission scanning electron microscopy (fe-sem), fourier tra...

In this paper, synthesis of the flower-like zinc oxide was performed using microwave assisted dicationic ionic liquid [mmp(im)2 ]Br2 . The polycrystalline flower-like zinc oxide nanostructure was obtained when a suitable mole ratio (ionic liquid /zinc acetate) and short duration microwave was used. X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL) spectra w...

a feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. the nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. fourier transform infrared spectroscopy (ft-ir), scanning electron microscopy/energy dispersive x-ray spectrometry (sem/eds) and x-ray d...

OBJECTIVES Recurrent caries was partly ascribed to lack of antibacterial properties in composite resin. Silver and zinc nanoparticles are considered to be broad-spectrum antibacterial agents. The aim of the present study was to evaluate the antibacterial properties of composite resins containing 1% silver and zinc-oxide nanoparticles on Streptococcus mutans and Lactobacillus. MATERIALS AND ME...
