in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
polyvinylpyrrolidone / nickel oxide (pvp/nio) dielectrics were fabricated with sol-gel method using 0.2 g of pvp at different working temperatures of 80, 150 and 200 ºc. structural properties and surface morphology of the hybrid films were investigated by x-ray diffraction (xrd) and scanning electron microscope (sem) respectively. energy dispersive x-ray spectrosc...
In this paper, Bi1.66Pb0.34Sr2Ca2Cu3O superconductor powders have been prepared via sol-gel and solid-state reaction methods. The structural and magnetic properties have been studied by the X-Ray diffraction (Fullprof analysis) and magnetic susceptibility measurements. The superconductivity and structural properties of the samples have been compared with the properties of a commercially availab...
lta zeolite nanoparticles was successfully synthesized from clear solution under controlled conditions using hydrothermal method using tetramethyl ammonium hydroxide as a structural directing agent. the as-synthesized lta zeolite particles were characterized by powder x-ray diffraction (xrd) analysis, scanning electron microscopy (sem), fourier transform infrared (ft-ir) spectroscopy, energy di...
clay minerals are considered the most important components of clastic reservoir rock evaluation studies. the shurijeh gas reservoir formation, represented by shaly sandstones of the late jurassic-early cretaceous age, is the main reservoir rock in the eastern kopet-dagh sedimentary basin, ne iran. in this study, x-ray diffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopic (s...
