Mesoporous WO3•0.33H2O was synthesized by the microwave radiation method using surfactant as the template-directing agent, and the template was removed by Soxhlet extraction. The degree of framework substitution had been monitored by means of powder X-ray diffraction (XRD), nitrogen adsorption, and UV-vis diffuse reflectance (DRUV) spectroscopy techniques. Nitrogen adsorption data and XRD patterns confirmed that, the structure, high surface area, and uniform pore size distribution were maintained in the crystallized samples. The photocatalytic activity for the photo-oxidation of gaseous formaldehyde on the mesoporous WO3•0.33H2O synthesized was improved by NiO loading, the photocatalytic activity was higher than both that of the materials synthesized using calcination in high temperature and commercial Degussa P25 TiO2 under visible light and UV irradiation.

Crosslinked amphoteric starches (CAS) with quaternary ammonium cationic and carboxymethyl anionic groups were prepared by a microwave radiation method. Their adsorption behavior for Cr(VI) was investigated. The results showed that high the degree of substitution (DS) of modified starch was favorable to the synthesis by the microwave heating and crosslinked amphoteric starches prepared with higher the adsorption capacity than by the drying reaction. The adsorption capacity increases with the increasing cationic groups and decreased with increasing degree of substitution of anionic groups. The adsorption capacity was found to follow the Langmuir isotherm.

There is a wide range of experimental results related to dislocations in diamond, group IV, II-VI, III-V semiconducting compounds, but few of these come from isolated, well-characterized individual dislocations. We are here concerned with only those results obtained in a transmission electron microscope so that the dislocations responsible were individually imaged. The luminescence properties of the dislocations were studied by cathodoluminescence performed at low temperatures (~30K) achieved by liquid helium cooling. Both spectra and monochromatic cathodoluminescence images have been obtained, in some cases as a function of temperature.There are two aspects of this work. One is mainly of technological significance. By understanding the luminescence properties of dislocations in epitaxial structures, future non-destructive evaluation will be enhanced. The second aim is to arrive at a good detailed understanding of the basic physics associated with carrier recombination near dislocations as revealed by local luminescence properties.
