highly crystalline bi3+-doped cadmium oxide (cdo) sub-micron structures were synthesized by calcination the obtained precursor from a sol-gel reaction. the reaction was carried out with cadmium nitrate (cd(no3)2.4h2o), bismuth nitrate (bi(no3)3.5h2o) and ethylene glycol (c2h6o2) reactants without any additives at 80°c for 2h. resulting gel was calcined at 900 °c with increasing temperature rate...

nano structured materials have wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. copper oxide nano materials are of interest on account of their potential uses in many technological fields. in this study  cuo nanoparticles were synthesized via simple sol gel method using basic cuso4 as we...

stoichiometric tetragonal bal-xsrxtio3 (x = 0.23) nanopowders were prepared by stearic acid gel(sag) method using barium stearate, strontium stearate, tetrabutyl titanate as ba, sr, ti sourcesand stearic acid as complexing reagent. thermal analysis including differential thermogravimetric(dtg) and tg, fourier transform infrared spectrometry (ftir), x-ray diffraction (xrd) andtransmission electr...

zinc oxide (zno) nanopowders were synthesized by the sol–gel method from an ethanol solution of zinc sulfate heptahydrate in the presence of diethylene glycol surfactant. detailed structural and microstructural investigations were carried out using x-ray diffraction (xrd), high-resolution transmission electron microscopy (hrtem), field emission scanning electron microscopy (fe-sem), fourier tra...

mntio3-zeolite-y nanocomposites were synthesized with 5-10-20% (w/w) of mntio3 by stearic acid gel method. then, the gels were calcined at 900 °c for 4 hours and the resulted spectra were investigated at 20% (w/w) concentration. also, the presence of rhombohedral phase of mntio3 in zeolite-y matrix was confirmed by xrd, sem, edx and bet. the vsm results showed the antiferromagnetic properties f...

highly sinterable alumina nano-powders have been synthesized by a sol-gel combustion method with glycine asfuel. the preparation involved the thermal decomposition of a chelating agent (fuel)-nitrate gel and theformation of amorphous precursors. the nanopowders calcined at 1100°c were characterized by x-ray powderdiffraction (xrd) and scanning electron microscopy (sem). it was found that the ch...

nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a ba:fe molar ratio of 1:10. the effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. the results revealed that the formation of barium hexaferritefine particles is influenced by mo...
