The effect of milling process on TiO2 nanopowders and functional properties of TiO2 coated cotton fabric was investigated. The XRD analysis reveals that the milled TiO2 nanopowders reduce its size in Nano scale when milling time increases. SEM analysis reveals that the milled TiO2 powder shows a seed-like structure. FTIR spectra show the presence of […]
Sol–gel auto-combustion is a unique combination of the combustion and the chemical gelation processes. In this work, nanosize (d) powders with compositions of ZnFe2O4 were synthesized by sol–gel combustion method. The puffy, porous brown powders as-combusted was calcined at the temperature of 750–1000◦C for 4 h. These powders are characterized by X-ray diffraction and scanning […]
CoTiO3-clay nano-composites were synthesized via a conventional sol-gel method; the gel was calcinated at 500 – 800°C for 2 hours. The presence of rhombohedra phase of CoTiO3 in clay matrix was confirmed by XRD, FTIR, SEM. Cobalt titanate-clay nano-composites were prepared with 5-20%(w/w) by sol-gel method. The spectra results were investigated at 20% (w/w) concentration […]
The magnetite (Fe3O4) – agar nanocomposite was prepared by co-precipitation of Fe (III) and Fe (II) ions for the first time. The obtained samples were characterized by x-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscopy and transmission electron microscopy. FT-IR results confirm the formation of Fe3O4 nanoparticles in agar matrix. The XRD results revealed the […]
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 nanoparticles were studied […]
The present investigation evaluates the potential of aqueous seed extract of Abrus precatorius L. for the biosynthesis of silver nanoparticles (AgNPs). The structure of AgNPs was authenticated by the changes in colour as well as the UV-vis spectroscopy, which showed an absorbance maxima peak at 441 nm. The scanning electron microscope (SEM) investigation proved the […]
