in this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. the benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (ch3coo)2cu.h2o individually as cu sources. al...

Diffraction peak profiles were calculated numerically for dislocation ensembles with different spatial arrangements and correlations between the Burgers vector signs. The latter property determines stored elastic energy in crystal width of diffraction peaks. It is shown that within approximation asymptotic line-profile theory relationship breadth magnitude modified Williamson-Hall (mWH) plot li...

Neutron diffraction study of nanostructured magnetite was performed at room temperature. The actual grain-size was determined from evaluation of X-ray diffraction profiles by the modified Williamson-Hall plot. The atomic structure parameters and the sublattice magnetic moments were determined using the Rietveld refinement of the neutron diffraction spectra. The sublattice magnetization at the o...

Nanocrystalline silicon embedded carbide, nc-Si(SiC) thin films were deposited on p-type substrates by using a thermal chemical vapor deposition (CVD) with different process temperatures from 700 to 1000 °C. The SEM images reveal the Si particles are SiC films. estimated crystallite size of was varied 14 28 nm and 40.7 61 respectively Scherrer formula Williamson – Hall formula. Similarly, latti...

ZnO nanoparticles (ZnO-NPs) were prepared by a solegel combustion method from a zinc acetate precursor and acetic acid. The ZnO-NPs were synthesized at calcination temperatures of 650 C and 750 C for 1 h. The synthesized ZnO-NPs were characterized by X-ray diffraction analysis (XRD) and TEM. The XRD results revealed that the sample product was crystalline with a hexagonal wurtzite phase. Highma...

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...
