In the present study, pure Aluminum powder with 5%wt Titanium Dioxide was mechanically milled at different times. Using phase analysis through X-ray diffraction (XRD), it was found that increasing of the milling times over 10 hours causes the reduction of Titanium by Aluminum and formation of Al2O3 in the structure. Also, it was shown that if the process persists, Aluminum reacts with Titanium ...
In this paper TiB2-TiC/Ni cermet with various Ni (20, 40 and 60 wt %) content were synthesized by mechanically activated self-propagating synthesis (MASHS) and effect of the addition of Ni on synthesis parameters and microstructure of synthesized samples were investigated. First raw materials (B4C, Ti and Ni) milled in Ar atmosphere. Then milling powders analyzed by XRD. In next step powders sy...
In this research, Zn0.97Cu0.03O nanoparticles are prepared by sol-gel method using various stabilizers (Mono, Di, and Tri-ethanolamine). The effect of stabilizers on the structural, morphological and optical properties of the nanoparticles were investigated. Study of X-ray diffraction pattern shows the hexagonal wurtzite structure of samples. The crystallite size, strain, stress, and deformatio...
Pristine Antimony tungstate nanoparticles prepared via a simple hydrothermal process showcase interesting photocatalytic efficiency, degrading Methylene Blue (MB) completely in 180 min under visible light. In this study, the impact on crystalline quality and related optical properties as well efficiency of antimony due to temperature variation during synthesis are explored. While X-ray diffract...
Abstract In this research, structural, magnetic, electrical, and optical properties of Al 3+ substituted Ba 0.6 Sr 0.4 Ti 1-x x O 3 ceramics (where = 0.00 to 0.20) have been investigated discussed. The ceramic samples successfully synthesized by the conventional solid-state reaction method. crystallinity prepared has confirmed x-ray peak broadening techniques such as Williamson Hall (W-H) plot ...

In this study, corrosion behavior of copper that was deformed by Simple Shear Extrusion (SSE) method was investigated in 3%wt NaCl solution. Modified Williamson-Hall method, applied on the X-ray diffraction patterns of the samples, showed that increase in the number of SSE passes led to increasing in the dislocation density in the copper samples. Moreover, such deformed samples exh...
Fall Winter 2012, Vol. 22, Number 1 Page 36 L style theories have been cited as an effective means for helping teachers recognize the incredibly diverse needs students bring into the classroom (Felder & Brent, 2005; Hall & Mosely, 2005; Sternberg, Grigorenko, & Zhang, 2008; Williamson & Watson, 2007). According to Zapalska and Dabb (2002), an understanding of the way students learn improves the...
