In this study, we have reported the green synthesis magnesium ferrite using tragacanth gel by the sol-gel method without using any organic chemicals. The sample was characterized by powder X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM) and scanning electron microscopy (SEM). The X-ray powder diffraction (XRD) analysis revealed the fo...
Bio-inspired silver nanoparticles were synthesized with the aid of a novel method, using leaves of the plant Nigella sativa. After drying the leaves in air, they were first sweltered in boiling distilled water and the liquid was filtered subsequently. The result was the brothused to reduce solutions including various concentrations of silver nitrate in a proper amount of pH. The displayed UV&nd...
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 study, synthesis of silicon nitride by mechanical alloying and the effects of important parameters of milling time and heat treatment temperature, time and rate are presented. Silicon micro powder and nitrogen gas were used as precursor materials. Synthesized phases, morphology and particle size were investigated by X-ray diffraction pattern (XRD) and Field emission scanning electron mi...
introduction individual x-ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the x-ray diffraction patterns resulting from coherent scattering. the goal of this study was to introduce an optimized method for obt...
