Top-Emitting Organic Light-Emitting Devices Based on Silicon Substrate with High Luminance and Low Turn-on Voltage

We have fabricated a top-emitting organic light-emitting device on silicon substrate with high yellow luminance based on 5,6,11,12-tetraphenylnaphthacene sub-monolayer. It consists of a thin layer of highly conductive silver as the semitransparent cathode and surfaced-modified Ag as the anode. The device turns on at 3 V with the luminance of 8.4 cd/m^2. The maximum current efficiency is 1.3 cd/A at 6 V and the luminance reaches 14790 cd/m^2 at 14 V. The performance of the device is excellent in top-emitting organic light-emitting devices according to our knowledge.

HL-2A装置偏滤器位形下氢和碳的粒子通量比

等离子体-壁相互作用通过各种机制释放粒子，主等离子体中杂质的数量限制了装置的性能。要深入认识杂质释放的机制，测量和分析粒子通量非常重要。文献[1]中详细描述了用光谱方法测量托卡马克等离子体中来自局部表面的向内的杂质通量，文献[2]报道了用这种方法测定ASDEX装置ICRF加热条件下向内的铬的通量。

One—dimesional Infinite Chain Organotin Compounds： Synthesis and structural Characterization of Triphenyltin Thiazole—2—carboxylate and Triphenyltin 3—Pyridinylcarboxylate

Triphenyitin thiazole-2-carboxylate(1) and triphenyltin 3-pyridinylcar boxylate(2) were synthesized by the reaction of sodium thiazole-2-carboxylate or sodium 3-pyridinylcarboxylate with the triphenyltin chloride and their crystal structures were determined by single crystal X-ray diffraction analysis.In the structure of 1, the tin atom is five-coordinated in a distorted trigonal bipyramidal structure.Due to the presence of a close intermolecular Sn…S interaction distance of 0.3666nm,the structre can be described as a weakly-bridged on-dimensional chain compound.In the structure of 2,the tin atom is five-coordinated with bridging 3-pyridinylcarboxylate ligands N atom and resulting structure is one-dimensional chain compound.     

Synthesis, Spectroscopic Properties and Crystal Structures of Dibenzyltin（IV） Dithiobenzoate and Chlorodibenzyltin（IV） Thiobenzoate

Two dibenzyltin(IV) complexes with thiobenzoate ligand, (PhCH2)2Sn(SOCPh)2 (1) and (PhCH2)2Sn(C1)SOCPh (2), have been synthesized by the reaction of dibenzyltin(IV) dichloride with thiobenzoic acid in the presence of organic base Et3N and characterized by IR, ^1H NMR spectroscopy and elemental analysis. Their crystal structures were determined by X-ray single crystal diffraction analysis. In the crystals of 1, the tin atom is six-coordinated in a distorted octahedron configuration. In the crystals of 2, the molecular packing in unit cell reveals that the two adjacent molecules are symmetrically linked to each other to form a dimer with intermolecular Sn…C1 distances of 0.3591 (2) nm and the tin atom is five-coordinated in a distorted trigonal bipyramid configuration.

微量元素、抗氧化剂与湿热证的相关性的研究

建立了温病湿热证动物模型，研究了清香散对大鼠微旦元素锌（Zn）、硒（Se)、铜（Cu)和维生素E代谢水平，一氧化氮（NO）含量以及谷胱甘肽过氧化物酶（GSH－Px)活力变化的影响，并将正常对照组、湿热模型组、清香散治疗组进行两两比较。结果表明，湿热证模型大鼠血清Zn、Se、维生素E、NO含量显著下降，Cu含量显著升高，GSH－Px活力明显降低，经清热祛湿的经验方清香散治疗后，大鼠血清Zn、Se、维生素E、NO含量及GSH－Px活力明显升高，Cu含量明显下降。抗氧化能力下降是湿热证的本质之一，微量元素锌（Zn)、硒（Se)、铜（Cu)在机体内的含量反映了抗氧化酶活性的高低，清香散能显著提高大鼠血液Zn、Ee、维生素E、NO含量及GSH－Px活力，降低Cu含量，恢复其抗氧化能力。     

W51A的谱线与连续谱研究——CO,NH3谱线与3mm连续谱

以研究星系旋臂上大质量星形成区为目的，对W51 IRS1为中心的5′×4′(约等于11pc×9pc)天区的3.4mm的连续谱和CO(J=1.0)线作观测，并对NH₃(1,1),(2,2),(3,3)和(4,4)四反演线作同时观测.氨分子的谱形分析和辐射转移统计平衡计算结果表明,在波长3.4mm连续谱的W51 IRS1,IRS2以及(e1/e2)源中心方向的NH₃反演线谱有来自HⅡ区前的氨分子的相对发射线红移的吸收特征；由东部边缘区向中心,有密度3～10倍的递增趋势,进一步显示了光学不可见的分子云核的塌缩现象.在以IRS1为中心40″为半径的圆内的各个射电、近(远)红外、UCHⅡ源所形成的外场辐射对区内分子(例如NH₃)的激发产生不可忽略的影响.CO(J=1.0)的谱形在此圆区内由东到西发生由不对称的双峰(约等于60,68km·s^-1)转化为三峰,即与致密电离氢区G49.4-0.3成协的约等于53 km·s^-1分量亦在谱线上呈现.可见40″圆区内有明显的大质量星形成的各种活动迹象.
