| 1 | Preparation of photoanode and its application to flexible dye-sensitized solar cells显示文摘A TiO2 slurry was prepared by hydrothermal treating mixture of commercial TiO2 (P25),ethanol and distilled water in an autoclave.A flexible photoanode and dye-sensitized solar cell (DSSC) was fabricated on an ITO-coated poly (ethylene naphthalate) sheet (ITO/PEN) substrate by a doctor-blade technique.The sample was characterized with SEM,UV-vis,FTIR,and the photoelectric properties of the DSSC were measured.The influence of preparation conditions on the properties of the flexible DSSC was investigated.It is found that the TiO2 slurry hydrothermally treated in 185°C for 12 h has good stability and uniformity.Based on the slurry,a flexible DSSC with light-to-electric conversion efficiencies of 3.4% is achieved under irradiation with a simulate solar light intensity of 100 mW/cm2. | XIAO YaoMing,WU JiHuai,LI QingHua,XIE GuiXiang,YUE GenTian,YE HaiFeng,LAN Zhang,HUANG MiaoLiang & LIN JianMing Englineering Research Center of Environment-Friendly Functional Materials,Minsitry of Education,China The Key Laboratory for Functional Materials of Fujian Higher Education,Institute of Materials Physical Chemistry,Huaqiao University,Quanzhou 362021,China | 2010 | Chinese Science Bulletin2010，55，10： | 10 |
| 2 | Application of upconversion luminescence in dye-sensitized solar cells显示文摘An upconversion luminescence powder TiO2:(Er3+,Yb3+) is prepared by a hydrothermal method and used to fabricate dye-sensitized solar cell (DSSC).The TiO2:(Er3+,Yb3+) powder undergoes upconversion luminescence,converting infrared light which the dye can not absorb into visible light with wavelengths of 510-700 nm which the dye can absorb,increasing the photocurrent of the DSSC.TiO2:(Er3+,Yb3+) also acts as a p-type dopant,heightening the Fermi level of the oxide film,which increases the photovoltage of the DSSC.The best performance of the DSSC is found when the ratio of TiO2/luminescence powder is 1/3 in the luminescence layer.Under simulated solar irradiation of 100 mW cm-2 (AM 1.5),the DSSC containing TiO2:(Er3+,Yb3+) doping achieves a light-to-electricity energy conversion efficiency of 7.28% compared with 6.41% for the undoped DSSC. | XIE GuiXiang LIN JianMing WU JiHuai LAN Zhang LI QingHua XIAO YaoMing YUE GenTian YUE HaiFeng HUANG MiaoLiang | 2011 | Chinese Science Bulletin2011，56，1： | 6 |
| 3 | Astrocytic effect of low molecular weight heparin-superoxide dismutase conjugate in interleukin-6 overexpressing mice following local cerebral ischemia显示文摘BACKGROUND:Studies have shown that low molecular weight heparin-superoxide dismutase conjugate exhibits a remarkable neuroprotective effect. OBJECTIVE:To investigate the effect of low molecular weight heparin-superoxide dismutase conjugate on astrocytes in an interleukin-6(IL-6) overexpressing mice following local cerebral ischemia. DESIGN,TIME AND SETTING:Randomized,cytological,controlled,animal study was performed in the Department of Physiology and Neuroscience,Neurology and Biochemistry and Molecular Biology,Medical University of South Carolina from January 2005 to March 2005. MATERIALS:Nine IL-6 transgenic mice,irrespective of gender,were randomly divided into three groups:sham-operated,model,and treatment,with three mice in each group.With exception of the sham-operated group,right middle cerebral artery occlusion was induced in the mice. Expression of glial fibrillary acidic protein,an astrocyte marker,was determined by immunohistochemistry.Low molecular weight heparin-superoxide dismutase conjugate was purchased from Biochemistry and Biotechnique Institute,Shandong University. METHODS:Two minutes prior to ischemia induction,0.5 mL/kg saline or 20 000 U/kg low molecular weight heparin-superoxide dismutase conjugate were administrated via the femoral artery in the model group and treatment group,respectively.The sham-operated group underwent the same protocols,with the exception of occlusion and treatment. MAIN OUTCOME MEASURES:The number of glial fibrillary acidic protein-positive cells was quantified under light microscopy(x200). RESULTS:In the sham-operated group,there were a large number of astrocytes in the IL-6 transgenic mice.However,the cell bodies were small,and the branches were few and thin.The number of astrocytes in the model group was remarkably less than the sham-operated group. Compared to the model and sham-operated groups,the number of astrocytes significantly increased,and the cell body became larger,following treatment with low molecular weight heparin-superoxide dismutase conjugate.Astrocytes exhibited hypertrophy and hyperplasia,and the processes became longer and thicker. CONCLUSION:The low molecular weight heparin-superoxide dismutase conjugate may provide neuroprotection through astrocytic activation at the super-early stage of cerebral ischemia and reperfusion. | Yizhao Li Guixiang Cui Qingde Wang Hongxia Liu Xiaoxia Zhang Fengshan Wang Keqin Xie | 2009 | Neural Regeneration Research2009，4，2： | 1 |
