cobalt oxide (co3o4) nanoparticleshave been synthesized by hydrothermal method using mixture of cobalt(ii)chloride, triton x-100 and koh in an autoclave at 180 °c for 6 h followed by heating at 400 ºc for 3 h in air. the product have been characterized by fourier transform infrared (ft-ir), uv-vis spectroscopy, powder x-ray diffraction (xrd), scanning electron microscopy (sem) and transmission ...

in this paper, we used tetranuclear copper (ii) schiff base complexes, [cu4 (μ-sal2hn) (μ-n3)2(n3)2] (1) and [cu4 (μ-salophen) (μ1, 1-n3)2(n3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of cuo nanoparticles. the crystallinity, purity and morphology of the cuo nanoparticles were characterized by fourier transform infrared (ft-ir), x-ray diffraction (xrd) and s...

[1] The behavior of synthetic-powdered 57Fe-enriched enstatite (Mg0.980Fe0.020(5))(Mg0.760Fe0.240)Si2O6 has been explored by X-ray diffraction (XRD) and nuclear resonant inelastic X-ray scattering (NRIXS). The Pbca-structured enstatite sample was compressed in fine pressure increments for our independent XRD measurements. One structural transition between 10.1 and 12.2 GPa has been identified f...
