The study describes the antibacterial and anticancer activities of a nanocomposite prepared by mixing zinc oxide and titanium dioxide nanoparticles. The particle mixtures were analyzed by X-ray diffraction, Field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and dynamic light scattering techniques. Thus, analyzed samples were s...
the aluminum oxide materials are widely used in ceramics, refractories and abrasives due to their hardness, chemical inertness, high melting point, non-volatility and resistance to oxidation and corrosion. the paper describes work done on synthesis of α-alumina by using the simple, non-expensive solution combustion method using glycine as fuel.aluminum oxide (al2o3) nanoparticles were synthesiz...
the catalytic oxidation of toluene over copper oxide supported on natural diatomite was investigated. the catalyst was prepared by the wet impregnation method and characterized by using the brunauer emmett teller (bet), field emission scanning electron microscopy (fesem), x-ray diffraction (xrd), x-ray fluorescence (xrf) and temperature-programmed reduction (tpr) analysis. the highest catalytic ...
Nano-composite copper-zinc oxide (NCCZO) was deposited on borosilicate glass using a novel sol-gel/doctor-blade technique. The photocatalyst was prepared from copper acetylacetonate, zinc acetylacetonate, monoethanolamine (MEA) and citric acid monohydrate at 75 oC, aged for 1 d and annealed at 650 oC. The properties of the NCCZO nano-composite were investigated by X-ray diffraction (XRD) and fi...
mesoporous mgo microstructures were synthesized using magnesium acetate tetrahydrate, ammonium oxalate monohydrate and pluronic f127 via heating at 40 °c for 24 h and subsequent calcination. the mesoporous structure of magnesium oxide with the specific surface area of 47m2/g, pore volume 0.30 cm3/g and the average pore size 24 nm is produced. according to xrd stu...
synthesis, identification and thermal behavior studies of nanoparticles cobalt (ii) bromide has been studied in this research. cobalt (ii) bromide was synthesized by planetary high-energy ball mill. the general formula of this compound is cobr2.6h2o. the synthesized nanoparticles were characterized by fourier transform infrared spectroscopy and also size and structure of synthesized nanoparticl...
In the present study, binary oxide (cadmium oxide [CdO])x (zinc oxide [ZnO])1-x nanoparticles (NPs) at different concentrations of precursor in calcination temperature were prepared using thermal treatment technique. Cadmium and zinc nitrates (source of cadmium and zinc) with polyvinylpyrrolidone (capping agent) have been used to prepare (CdO)x (ZnO)1-x NPs samples. The sample was characterized...
Zinc oxide (ZnO) microrods were fabricated on graphene/SiO(2)/Si substrate by a simple hydrothermal route. The obtained products were characterized using X-ray powder diffraction, scanning electron microscopy, energy dispersive X-ray spectrometry, photoluminescence and UV-visible spectrometry. Microrods exhibits hexagonal wurzite structure. Some ZnO clusters and twinned ZnO structures were foun...
Zinc sulfide (ZnS) & zinc oxide (ZnO) nanoparticles was evaluated for their antimicrobial activity against four pathogenic strains. ZnS&ZnO nanoparticles were synthesized by simple aqueous chemical reaction in an aqueous solution. The main advantage of these nanoparticles (size of 10-30 nm) was that simply could be prepared by using cheap precursors in a cost effective and high throughput manne...
This paper has reported on the electrical and nonstructural of polymer-based materials in corporation NiO (Nickel oxide) in concentrations of 0.2%, 0.4% and 0.8% by weight of PVA (polyvinyl alcohol) polymer. Nanocrystallites phases and properties were characterized with using X-ray diffraction (XRD), Fourier transfer infrared radiation (FTIR),Energy distribution X-ray(EDX) techniques and X-Map ...
