sphere-like shaped cobalt oxide nanoparticles (co3o4) were synthesized by a simple wet chemical method using cobalt chloride as precursor and cetyl trimethylammonium bromide (ctab) as surfactant. their structural and surface morphologial properties were characterized by high resolution transmission electron microscopy (hrtem), field emission scanning electron microscopy (fesem) and x-ray diffra...

We describe a new technique for the synthesis of ultrahomogeneous nanoparticles of precursor oxalate powder by coprecipitation in the aqueous core of a water-in-oil microemulsion for the preparation of Bi-Pb-Sr-Ca-Cu-0 (2223) oxide superconductor. This process ensures a uniform mixing of metal cations down to a scale of at least 10 nm. This finely dispersed precursor powder results in phase pur...

introduction: the relation between morphine and nitric oxide release has been shown. due to important role of nitric oxide in regulation of skin blood flow, the aim of this study was to investigate the effect of nitric oxide synthase inhibitor (l-name) and nitric oxide synthesis precursor (l-arginine) on skin blood flow of intact and morphine-dependent rats. methods: skin blood flow of hind paw...

Polyimide nanotubes with tunable wall thickness were fabricated by a precursor impregnation method using an AAO template, and carbon nanotubes containing magnetic iron oxide were obtained using ferric chloride-embedded polyimide precursor by a carbonization process.

Nickel oxide nanotubes with great antibacterial activities, electrochemical capacitance, and magnetic properties have been synthesized through a precursor method with dimethylglyoxime as precipitant for the precursor, and the method has been developed for the synthesis of Ni/C nanorods.

Co-Promoted MoS2 model catalyst for fundamental hydrodesulfurization studies can be synthesized from a mixed Co and Mo oxide precursor.

In this study, mononuclear octahedral cobalt(III) Schiff base complex [CoL3], L = (5-bromo-2-hydroxybenzyl-2-furylmethyl)imine, was synthesized from the reaction of Co(NO3)2•6H2O and the Schiff base ligand L in methanol as solvent. It used as a new precursor to prepare spinel type cobalt oxide nanoparticles by a facile solid-state thermal decomposition. Controlling the temperature and time, Co3...

The fabrication of cobalt oxide nanotubes (length 3-4 μm, width 200-400 nm) was achieved by a colloidal templating approach. In this approach, a Co(III)-cysteinato complex [Co(en)2(S-cys)]2(BF4) was employed as the precursor of cobalt oxide. The infiltration behavior of the precursor into polyelectrolyte multilayers was studied with a quartz crystal microbalance which showed that the amount of ...

zinc oxide (zno) nanoparticles were synthesized by spray pyrolysis method using an aqueous solution of zinc acetate at various concentrations from 5 to 25 wt%. the decomposition of precursor solutions was carried out at 800, 1000 and 1200ºc under different atomizing pressures. the crystal structure and morphology of synthesized nanoparticles were characterized by x-ray diffraction (xrd) spectro...
