用四异丙醇钛镀膜在光催化下处理苯酚溶液

研究了用四异丙醇钛镀膜在光催化下对苯酚溶液进行转化。试验证明，镀膜厚度、源物质、镀膜条件均对苯酚溶液的转化率有影响。为实际处理苯酚废水提供了理论依据。     

Preparation of porous nanoparticle TiO_2 films for flexible dye-sensitized solar cells

A TiO2 paste was prepared by mixing commercial TiO2 (P25), ethanol, distilled water and a small amount of Ti (IV) tetrai-sopropoxide (TTIP), following by a hydrothermal treatment. Before hydrothermal treatment, a stirring for 48 h can prevent cracking TiO2 films. TTIP significantly promote the chemical connection between TiO2 particles and its adherence to the substrate, the TTIP amount of 6 mol% is suitable. UV irradiation can remove some impurities and water from the TiO2 film with an optimal time of 2 h....

UV irradiation can remove some impurities and water from the TiO2 film with an optimal time of 2 h. Transmission electron microscopy, X-ray diffraction, scanning electron microscopy and photovoltaic tests are charac- terized and measured. Shortcircuit current density, open-circuit voltage, fill factor and photoelectric conversion efficiencies for the fabricated flexible dye-sensitized solar cell are 7.20 mA cm-2, 0.769 V, 0.686 and 3.84%, respectively, under irradiation with a simulated solar light of 100 mW cm-2.     

国际知识产权执法制度发展及中国的应对

面对国际知识产权执法标准不断提高的趋势,对国际知识产权执法制度的发展过程进行了具体描绘。认为国际知识产权执法高标准的趋势将不可避免,但仍会留有例外条款等弹性空间。中国应提高自主创新能力,并同时对国际知识产权制度变化对我国企业可能产生的影响进行分析,为参与谈判建立数据基础。
