1Photocatalytic degradation of methyl orange using ZnO/TiO_(2) composites显示文摘ZnO/TiO_(2)composites were synthesized by using the solvothermal method and ultrasonic precipitation followed by heat treatment in order to investigate their photocatalytic degradation of methyl orange(MO)in aqueous suspension under UV irradiation.The composition and surface structure of the catalyst were characterized by X-ray diffraction(XRD),field emission scanning electron microscope(FE-SEM),and transmission electron microscopy(TEM).The degradation efficiencies of MO at various pH values were obtained.The highest degradation efficiencies were obtained before 30 min and after 60 min at pH 11.0 and pH 2.0,respectively.A sample analysis was conducted using liquid chromatography coupled with electrospray ionization ion-trap mass spectrometry.Six intermediates were found during the photocatalytic degradation process of quinonoid MO.The degradation pathway of quinonoid MO was also proposed.Ming GE Changsheng GUO Xingwang ZHU Lili MA Zhenan HAN Wei HU Yuqiu WANG 2009Frontiers of Environmental Science & Engineering2009,3,3:3

4Establishment of an animal model of extra-vertebral foramen cervical nerve entrapment by local electrical stimulation and selection of suitable stimulation parameters显示文摘A rat model of extra-vertebral foramen cervical nerve entrapment was established according to the following parameters:stimulation intensity 20 V;frequency 50 Hz;pulse width 200 μs;duration 333 ms/s for a total of 8 hours.After the electrical stimulation,rats exhibited mild muscle fiber atrophy,mild inflammatory exudates,connective tissue local fibrosis and chondrocyte metaplasia.Mean muscle fiber cross-sectional area was reduced.The nerve myelin sheath continuity was partially demyelinated.The microstructure of nerve cells was disrupted and these symptoms worsened with prolongation of the stimulation.The shoulder,neck and upper extremity muscles on the tested side demonstrated positive sharp waves and fibrillations.The severity increased with continuation of the stimulation.High amplitude and polyphasic motor unit potentials gradually appeared.Similar findings were seen in the contralateral side,but at a less severe level.Jinwu Wang Juliet Hou Qi Li Jian Tang Biyu Rui Shangchun Guo Haitao Jiang Cunyi Fan You Wang Zhenan Zhu Kerong Dai Guang H Yue 2011Neural Regeneration Research2011,6,29:0
