A novel tri(8-hydroxyquioline) aluminum (AlQ3) nanostructure was prepared on large scale at low cost by low-temperature physical vapor deposition (PVD). The morphologies, the chemical bondings, and photoluminescence of the AlQ3 nanostructure were investigated by environmental scanning electronic microscopy (ESEM), Fourier transform infrared spectrum (FT-IR), and photoluminescence (PL) spectra, respectively. The AlQ3 nanostructure was composed of micro-sphere with nanowire-cluster growing on the surface. The diameter of micro-sphere and nanowire were about 5 microm and 80 nm, respectively. FT-IR results indicated that the AlQ3 molecule had a strong thermal stability under research conditions. The growth mechanism of the novel nanostructure was discussed. The novel organic nanostructure would be believed to attractive building field-emission devices and other optical devices.

Simple chemical deposition was used to prepare three types of amoxicillin nanostructures. Their morphology and size were characterized by scanning electron microscopy, and their chemical bonds were examined by Fourier transform infrared spectrum. Our results show that amoxicillin nanobelts, nanofibers, nanoparticles, and microparticles can be obtained by changing the pH in solutions of amoxicillin sodium. To some degree the controllable growth of amoxicillin can be realized.

Ternary alloys of CdS xSe1− x nanorods have been synthesized by the thermal treatment of Cd2+ dispersed polyethylene glycol 2000 gel (PEG2000) with ethylenediamine solution of sulfur and selenium in a sealed system at 180 °C for 24 h, during which the proportion between S and Se in the nanorods was controlled by the ratios of every starting material to each other. The alloyed ternary CdS xSe1− x nanorods are highly crystalline without any other phase. The optical property these nanorods could be manipulated by modulating the composition of S and Se.

Abstract: Various α-MnO2 nanostructures have been successfully synthesized by a simple hydrothermal method based on the redox reactions between the MnO4 − and H2O in mixture containing KMnO4 and HNO3. The effect of varying the hydrothermal time to synthesize MnO2 nanostructures and the forming mechanism of α-MnO2 nanorods were investigated by using XRD, SEM and TEM. The results revealed an evolvement of morphologies ranging from brushy spherical morphology to nanorods depending upon the hydrothermal time. The surface area of the synthesized nanomaterials varied from 89 to 119m2/g. Electrochemical properties of the products were evaluated using cyclic voltammetry and galvanostatic charge–discharge studies, and the sample obtained by hydrothermal reaction for 6h at 120°C showed maximum capacitance with a value of 152F/g. In addition, long cycle life and excellent stability of the material were also demonstrated. [Copyright &y& Elsevier]

Abstract: A novel multilayer comb-like Zinc oxide nanostructure has been successfully synthesized via pure Zn chemical vapor deposition on anodic aluminum oxide substrate at 950°C. X-ray diffraction and selected area electron diffraction indicate that the nanocombs are of wurtzite structure and single crystalline. The morphology and the microstructure of the nanocombs are investigated by the scanning electron microscopy. Transmission electron microscopy shows the growth direction, and energy-dispersive X-ray spectroscopy reveals the atomic composition ratio of Zn/O. The growth mechanism of such interesting and unique morphologies is briefly discussed. [Copyright &y& Elsevier]
