气相Lys分子体系捕获双电子单重激发态的特性

采用密度泛函理论（DFT）中的B3LYP方法, 在6-311+G(2df)基组水平上, 对气相赖氨酸（Lys）分子和Lys^2-的基态稳定构型进行优化, 并用含时密度泛函理论（TD DFT)方法考察气相Lys分子和带电离子体系单重激发态的特性. 结果表明： Lys分子体系捕获双电子时, 其体系能量有所增加； S1单重激发态与S0基态能量差值变小； 分子体系的荧光波长增加； S7单重激发态跃迁轨道数减少.     

Influence of Microstructure and Sintering Routes on Transport Properties of Apatite Materials for Fuel Cells

1 Results Oxy-apatite materials are thought as zirconia-substitutes in Solid Oxide Fuel Cells due to their fast ionic conduction. However, the well known difficulties related to their densification prevent them from being used as such. This study presents strategies to obtain oxy-apatite dense materials and the influence of elaboration route on transport properties. Particular emphasis is put on the microstructure effect on ion conduction. By the combined use of freeze-drying and conventional or spark p...

STUDY ON POLYPYRROLE-VISCOSE CONDUCTING FIBER

The conductivity of Polypyrrole-viscose conducting fiber prepared with author's method can be shown up to as high as 2.106x10~(-2) S/cm. The main factors influencing the conductivity are the concentration of FeCl_3 used as dopant and initiator, the treatment time of viscose fiber as base material in FeCl_3 solution, temperature and polymerization time. It is found that the orientation and crystallization degree of viscose fiber keep constant before and after conducting treatment and the mechanical properties of conducting fiber is the same as that of base material. In addition, the distribution of polypyrrole in viscose fiber, and its effect on the conductivity were investigated in details by TEM.
