[Photoluminescence of Silicon Nitride-Based ZnO Thin Film Developed with RF Magnetron Sputtering].

Owing to its merits of high corrosion resistance, high temperature stability as well as good mechanical strength etc., silicon nitride membrane (SiN) has been widely used as the experimental carrier of transmission electron microscope (TEM), scanning electron microscopy (SEM), atomic force microscope (AFM), X-ray photoelectron spectroscopy (XPS), energy dispersive X-Ray spectroscopy (EDX) and other characterization. In particular, SiN can be used as a low disturbing background for SEM observation.

[Study on Photocatalytic Performance of LaPO4 Nanorods with Different Crystal Phases].

Rare earth phosphate has a wide application in optical materials, laser materials and many fields with great development prospects. In this paper, LaPO4 nanorods with different crystalline phases are prepared with hydrothermal method, its photocatalytic performance are discussed, as well as the structure and UV diffuse reflectance spectroscopy. The research indicates that the hydrothermal temperature plays a key role in the crystal phase, while it is hexagonal at 120 ℃, monoclinic at 180 ℃ and the mixed phase at 160 ℃.

[Standard sample preparation method for quick determination of trace elements in plastic].

Reference sample was prepared by masterbatch method, containing heavy metals with known concentration of electronic information products (plastic), the repeatability and precision were determined, and reference sample preparation procedures were established. X-Ray fluorescence spectroscopy (XRF) analysis method was used to determine the repeatability and uncertainty in the analysis of the sample of heavy metals and bromine element. The working curve and the metrical methods for the reference sample were carried out.

[The research on IR and TEM of polybutylcyanoacrylate nanoparticles].

Through latex polymerization with stabilizer (Dextran, low fraction), we prepared polybutylcyanoacrylate nanoparticles with a size of approximately 200 nm. The nanoparticle diameter decreases with decreasing stabilizer concentration. Using TEM and IR we studied the combination state and the mechanism between polybutylcyanoacrylate and Dextran.

[Raman spectrum research on structure and performance of nanometer TiO2 film photocatalyst supported on stainless steel netweb].

Crystal structure, particle size and thickness of film titania as photocatalyst on stainless steel netweb synthesized by sol-gel was studied by Raman spectroscopy. It was showed that diffusion of Fe in the base was banned when certain thickness of the film was obtained; when the film was calcined at 400 degrees C, it was anatase, and when the calcining temperature exceeded 400 degrees C, rutile came up in the film. The characteristic Raman peak of anatase shifted, which showed that the particle size of the film was changing, and from calculating, the size was about 10.

Chemiluminescence determination of chlorinated volatile organic compounds by conversion on nanometer TiO2.

A novel method based on conversion of chlorinated volatile organic compounds (CVOCs) to chlorine using a new type of column packed with nanometer TiO2 coupled with chemiluminescence (CL) has been developed for determination of them in workplace air. CVOCs are converted to chlorine by nanometer TiO2 at 220 degrees C. The Cl2 that is produced is selectively enriched on the column and subsequently released from the column at 600 degrees C.
