| 2 | Effect of platinum on the photocatalytic degradation of chlorinated organic compound显示文摘TiO 2 nanoparticles, doped with different Pt contents, were prepared by a modified photodeposition method using Degussa P-25 TiO 2 , H 2 PtCl 6 ·6H 2 O and methanol as the solvents. The physicochemical properties of Pt/TiO 2 were investigated by the nitrogen adsorption and desorption isotherm measurement technique, X-ray diffraction analysis and photoluminescence spectra, respectively. Reaction rates from photocatalytic removal of dichloromethane over Degussa P-25 TiO 2 and Pt/TiO 2 were evaluated. The average diameter and BET surface area of the TiO 2 catalyst particles were 300 nm and 50 m 2 /g, respectively. The degradation efficiency was 99.0%, 82.7%, 55.2%, and 57.9% with TiO 2 at inlet concentrations of 50, 100, 200, and 300 ppm, respectively. And the degradation efficiency was 99.3%, 79.7%, 76.5%, and 73.4% with a 0.005 wt.% Pt/TiO 2 at inlet concentrations of 50, 100, 200, and 300 ppm, respectively. In addition, we found that the photoluminescence emission peak intensities decreased with increases in the doping amount of Pt, which indicates that the irradiative recombination was weakened. Furthermore, the results showed that the UV/0.005 wt.% Pt/TiO 2 process was capable of efficiently decomposing gaseous DCM in air. | Chih Ming Ma Ya Wen Lee Gui Bing Hong Te Li Su Je Lueng Shie Chang Tang Chang | 2011 | Journal of Environmental Sciences2011，23，4： | 5 |
| 11 | O-GIcNAc transferase regulates centriole behavior and intraflagellar transport to promote ciliogenesis显示文摘Dear Editor,O-GIcNAcylation is a nutrient sensor that is particularly sensitive to environmental glucose(Hardiville and Hart,2014).Glucose can be converted to UDP-GIcNAc through the hexosamine biosynthetic pathway,providing a substrate for O-GIcNAcylation.Two enzymes participate in this reversible modification,O-GIcNAc transferase(OGT),which adds a single GIcNAc residue to the serine/threonine sites of proteins,and O-GIcNAcase(OGA),which removes the residue(Yang and Qian,2017). | Fan Yu Te Li Yanchao Sui Qingxia Chen Song Yang Jia Yang Renjie Hong Dengwen Li Xiumin Yan Wei Zhao Xueliang Zhu Jun Zhou | 2020 | Protein & Cell2020，11，11： | 0 |
