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...

X-ray diffraction analysis is one of powerful tools on the dislocation and this method can be applied reasonably for many metals with isotropic crystal structure such as bcc fcc. In study, modified Williamson-Hall was martensitic steels containing 0.006 – 0.26 mass% carbon proved that value density increases increasing content. However, solute have bct characterized by different lattice constan...

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...

Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...

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...

In this research, calcium titanate nanoparticles have been synthesized via mechanical alloying (MA). By changing the parameters of mechanical alloying, optimal conditions for synthesis of this compound was determined. For synthesis of this compound, a mixture of calcium hydroxide and titanium dioxide, rotation speed of 250 rpm and differnet ball to powder weight ratio was used. Phase investigat...

Mn doped ZnO nanocrystals were prepared by co-precipitation route sintered at 450 °C temperature. XRD results indicate that the samples having hexagonal (wurtzite) structure. From X-ray data it is found that the lattice parameters increase with increasing Mn concentration. The X-ray density decreases with increasing Mn concentration of Zn 1-x Mnx O nanocrystals. It indicates that the Mn...

If a Williamson matrix of order 4w exists and a special type of design, a set of Baumert-Hall units of order 4t, exists, then there exists a Hadamard matrix of order 4tw. A number of special Baumert-Hall sets of units, including an infinite class, are constructed here; these give the densest known classes of Hadamard matrices. The constructions relate to various topics such as pulse compression...
