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...

x-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of fe-10ni-7mn (wt. %) maraging steel. integral peak breadths were analyzed using classical williamson-hall equation taking the elastic anisotropy into account. it was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...

In this study, SnO2 nanoparticles were prepared from cost-low tin chloride (SnCl2.2H2O) and ethanol by adding ammonia solution the sol-gel method, which is one of lowest-cost simplest techniques. The dried in a drying oven at temperature 70°C for 7 hours. After that, it burned an 200°C 24 structure, material, morphological, optical properties synthesized nanoparticle sizes are studied utilizing...

In this study, nano graphene oxide (NGO) was synthesized by modified Hummer's method, the functionalization surface of amino acid (methionine, cysteine) covalent NGO with group using microwave 20% power (140 W) and characterization Fourier transform infrared spectrophotometer (FT-IR), X-ray diffraction spectroscopy (XRD), field emission scanning electronic microscopy (FESEM). The calculated par...

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...
