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 ...

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...

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...

AlMgCu alloy samples with 70 wt.% Al and varying Cu Mg compositions have been fabricated. The fabricated were characterized by x-ray diffraction measurement the patterns obtained. also subjected to hardness tensile tests determine mechanical properties. A study of was done average crystallite size internal strains using Scherrer’s formula Williamson–Hall analysis, assuming uniform deformation m...

in this research, kinetics of carbothermic reduction of molybdenite in the presence of different amounts of sodium carbonate has been studied. mixed powders consisting of molybdenite, graphite and sodium carbonate with three mole-ratios of 1:4:2,1:4:3 and 1:4:4 were mechanically activated for 40 hours. the results of x-ray diffraction on activated samples showed that no reaction occurrs in diff...
