Anodization Method

Erbium salt was used as additives for the first time in preparing anodic aluminum oxide (AAO) films to improve its performance. AAO films were prepared from a 15 vol. % sulphuric acid solution containing erbium salt by anodization method; the effects of concentration of erbium on microhardness and thickness of AAO film were researched, respectively. The effect of heat treatment temperature on structure of AAO film was researched. AAO films were characterized by XRD, EDAX and SEM techniques, respectively. The microhardness and thickness of AAO film were 378.5HV and 82μm respectively, which were higher 12.99% and 17.14% than those of the film prepared in electrolyte of nothing addition erbium salt respectively. The aperture of AAO film was more uniform and the surface of AAO film was smoother than those of films prepared in electrolyte of nothing addition erbium salt. The apertures of AAO film were in 25~30nm. There was not erbium in AAO film. AAO films were amorphous when heat treatment temperatures of AAO film were below 800°C, when heat treatment temperature of AAO film were 850°C and 1000°C respectively, and AAO films were γ-Al2O3and α-Al2O3film respectively.

The ambient temperature ultraviolet absorption and the 77 K luminescence spectra of a series of four hydrocarbon derivatives of azulene in sulfuric acid solution are presented and discussed in detail. CNDO/S calculations have been carried out and the calculational results are compared with the experimental results. The phosphorescences of these cationic species are reported for the first time. The present results suggest that an inversion in the order of electronic states is perhaps responsible for the normal emissions of the protonated species and the anomalous emissions of the parent molecules.

AbstractPhotochemical redox reaction tests were corried out where the experimental variables were irradiation rate using a Hg lamp light and molarity of nitric acid containing different reductant reagents such as hydroxylamine(HAN), hydrazine(HDZ) and urea. Based on these tests, we confirmed that the valences of Pu and Np were easily photochemically adjusted to two conditions of Pu(IV,VI)-Np(V) and Pu(IV,VI)-Np(VI), indicating that photochemical valence adjustment for the separation and co-extraction of Pu and Np has excellent potential as an advanced process technology.
