| 1 | Relationships of surface oxygen vacancies with photoluminescence and photocatalytic performance of ZnO nanoparticles显示文摘The ZnO nanoparticles are prepared by a precipitation process, and also are char- acterized by means of the modern testing techniques such as XPS, ESR, SPS and PL. The ac- tivity of the as-prepared ZnO is evaluated in the photocatalytic oxidation of gas phase n-C7H16. The relationships of surface oxygen vacancies (SOV) with photoluminescence (PL) and photo- catalytic performance are discussed in details. The results show that the smaller the particle size, the larger the SOV content, the stronger the PL signal, the higher the photocatalytic activity, in- dicating that the SOV, PL and photocatalytic activity have inherent relationships. This was be- cause of the reasons that the PL signal is attributed to the free and binding excitons resulting from the SOV, while the SOV is favorable for a photocatalytic oxidation reaction since the SOV can easily capture the photoinduced electrons, and the captured electrons had strong interac- tions with the adsorbed oxygen. In addition, the surface states of ZnO nanoparticles, arising from the SOV and oxygen species, are very abundant. | JING Liqiang YUAN Fulong HOU Haige XIN Baifu CAI Weimin FU Honggang | 2005 | Science China Chemistry2005，48，1： | 3 |
| 2 | An Inverse Kinematic Analysis Modeling on a 6-PSS Compliant Parallel Platform for Optoelectronic Packaging显示文摘Multiple degree of freedom motion platform is always one of the important components in optoelectronic packaging systems,its characteristics have a vital impact on the performances of optoelectronic packaging.This paper presents a 6-Prismatic-Spherical-Spherical compliant parallel platform for optoelectronic packaging.This platform is a kind of parallel layout structure,which uses the piezoelectric motors as active joints and the large-stroke flexure hinges are employed as passive joints.An inverse kinematic modeling based on elastokinematic analysis is analyzed and deduced.The elastokinematic analysis considers the elastic deformation of the large-stroke flexure hinges in movement process,and improves the positioning accuracy of the compliant parallel platform in applications.The finite element analysis model and the prototype of the compliant parallel platform are developed,and the validity of the proposed method is finally verified.This paper provides a theoretical reference and experimental data for the inverse kinematic analysis of six degrees of freedom motion compliant parallel platforms with large-stroke flexure hinges. | Fulong Hou Meizhu Luo Zijiao Zhang | 2019 | CES Transactions on Electrical Machines and Systems2019，3，1： | 0 |
