[Show abstract][Hide abstract] ABSTRACT: The nanocrystalline CuO powders were prepared by precipitation method using Cu(NO3)2 as copper raw material, water and ethanol as dispersants, and NaOH and ammonia solution as precipitates. The structure, particle
size and morphology of resulting CuO powders were characterized by X-ray diffraction (XRD), field-emission scanning electron
microscopy (SEM) and transmission electron microscopy (TEM). The mechanism of CuO formation was discussed.

[Show abstract][Hide abstract] ABSTRACT: Delicate double tower-like ZnO have been fabricated through the decomposition of the zinc nitrate hexahydrate (Zn(NO3)26H2O). The phase transformation and morphology evolution of the products were carefully studied and investigated with X-ray diffraction,
scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and Raman spectra. The resultant
results indicated that the obtained double tower-like ZnO materials possess pure wurtzite hexagonal phase, growing along the
 direction. A reasonable formation mechanism was also presented in this paper.

[Show abstract][Hide abstract] ABSTRACT: Synthesis of flower-shaped ZnO nanostructures composed of ZnO nanosticks was achieved by the solution process using zinc acetate
dihydrate, sodium hydroxide and polyethylene glycol-20000 (PEG-20000) at 180°C for 4 h. The diameter of individual nanosticks
was about 100 nm. Detailed structure characterizations demonstrate that the synthesized products are wurtzite hexagonal phase,
grown along the  direction. The infrared (IR) spectrum shows the standard peak of zinc oxide at 571 cm−1. Raman scattering exhibits a sharp and strong E
2 mode at 441 cm−1 which further confirms the good crystal and wurtzite hexagonal phase of the grown nanostructures.
