Abstract: In(OH)(3) nanostructures with controllable shapes were successfully synthesized using indium nitrate as an indium source by one-step electrodeposition process. The influences of the reaction temperature, time, indium nitrate concentration, and the applied potential on the morphology of the obtained products were discussed in detail. The results revealed that the growth behavior of In(OH)(3) was mainly determined by the indium nitrate concentration and applied potential, and well-defined ellipsoids, cubes, and rods could be prepared under suitable conditions. Their possible growth mechanisms as well as photocatalytic applications were addressed. Furthermore, In(2)O(3) nanostructures were obtained from In(OH)(3) upon heating, while size and morphology can be maintained during this process.

Abstract: Vertically aligned ZnO nanotubes were prepared by etching ZnO rod arrays in aqueous solution, which were previously developed by chemical bath deposition method. The morphological, structural, photoluminescence, as well as photocatalytic properties of the ZnO nanotubes were examined with respect to the pH values of chemical bath solution. The morphology of the products was found to be sensitive to the pH values and chemical bath temperatures. The nanotubes synthesized at a low pH value (5.82) exhibited a strong UV emission and a weak defect-related visible emission. The highest photocatalytic efficiency was also observed at pH = 5.82. The possible mechanism for the difference of photocatalytic efficiency was discussed.

Abstract: This paper reports the use of high performance size exclusion chromatography (HPSEC) as a tool to assess NOM removal by coagulation. Quantitative information such as percentage removal can be determined after "peak-fitting" the HPSEC molecular weight profile of the source water. A peak-fitting approach was developed based on the molecular weight profile of dissolved organic matter from surface water. A sequential jar testing procedure with five treatment steps was used to characterize organics and to confirm that several NOM components were recalcitrant to coagulation with alum. Despite differences found in both the concentration and character of NOM in three surface waters studied, the final concentrations and characteristics (e.g., molecular weight profile) were very similar after five treatment stages. The molecular weight profiles of the recalcitrant organics were subsequently used to build a peak-fitting technique for NOM removal. The approach was validated by further jar test results of several other water sources, such as ground and river waters, including one found to be very difficult to treat in terms of NOM removal by alum treatment. Predictions of removable and nonremovable organic fractions by coagulation using this peak fitting technique were found to be within 10% of actual values.
