Description: The study focuses on the degradation of fulvic acid by nano-structured TiO"2 in a submerged membrane photocatalysis reactor (SMPR). It has been demonstrated that the composite TiO"2 photocatalyst could be automatically settled due to its gravity and then be easily separated by MF membrane. In addition, it was more efficient to maintain high flux of membranes than that of commercial TiO"2 P25. The paper describes the effects of operational parameters on the photocatalytic degradation of fulvic acid in SMPR. It was found that the photocatalyst at 0.5g/L and airflow at 0.06m^3/h were the optimal condition for the removal of fulvic acid (FA) and the FA degradation rate was higher at acidic condition than that at alkalinous media. In order to compare the effects of different filtration duration on permeate flux rate of MF, P25 powder and nano-structured TiO"2 were employed. According to the experiments, the permeate flux rate of MF is improved and thus the membrane fouling phenomenon is reduced with the addition of nano-structured TiO"2 catalyst. Therefore, the submerged membrane photocatalysis reactor can be potentially applied in photocatalytic oxidation process during drinking water treatment. .

Physics and Chemistry of Nano-structured Materials
The development of nanostructured materials represents a new and fast evolving application of recent research in physics and chemistry. Novel experimental tools coupled with new theory have made this possible. Topics covered in this book include nanocrystals, semiconductor heterostructures, nanotubes, nanowires, and manipulation and fabrication techniques. The core of the book consists of ten lectures by five distinguished researchers, Paul Alivisatos, D.D. Awschalom, Sumio Iijima, Charles Lieber and Phaedon Avouris, presented at an Advanced Study Institute in Hong Kong in January 1999. It should interest materials physicists and chemists as well as materials scientists with an interest in the growth and characterisation of sophisticated materials..

Studies on electrochemical behaviors of acyclovir and its voltammetric determination with nano-structured film electrode [An article from: Analytica Chimica Acta]
This digital document is a journal article from Analytica Chimica Acta, published by Elsevier in 2006. The article is delivered in HTML format and is available in your Amazon.com Media Library immediately after purchase. You can view it with any web browser. Description: A multi-wall carbon nanotubes (MWNTs)-dihexadecyl hydrogen phosphate (DHP) film-coated glassy carbon electrode (GCE) was fabricated, and the electrochemical behaviors of acyclovir on the MWNTs-DHP film-coated GCE were investigated by using cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS) and chronocoulometry (CC). The oxidation peak current of acyclovir increased significantly and the peak potential shifted negatively at the MWNTs-DHP film-modified GCE, compared with that at a bare GCE. The results showed that this nano-structured film electrode exhibited excellent enhancement effects on the electrochemical oxidation of acyclovir. Consequently, a simple and sensitive electroanalytical method was developed for the determination of acyclovir. The oxidation peak current was proportional to the concentration of acyclovir from 8.0x10^-^8 to 1.0x10^-^5mol/L. The detection limit was about 3.0x10^-^8mol/L for 60s accumulation at 0.00V. The proposed method was demonstrated by using acyclovir tablets and the result was satisfying. .
