Dye sensitization is a fundamental function for solar cell and silver halide (AgX) microcrystal to increase the optoelectronic conversion efficiency. In this paper, the spectral properties and self-assembled structure of three types of cyanine dyes, adsorbed both on (100) surface of 0.4 μm AgBr cubic crystal and (111) surface of 1.8 μm AgBr tabular crystal, were studied with combination of spectroscopy and atomic force microscopy (AFM) technique. Rectangular aggregation structure is formed on the crystal faces of (100) and (111) for both anionic and cationic dyes, while herringbone-stacking structure is formed by anionic-cationic dye, and a J-band spectrum is correspondingly detected. The photoelectron property of dye-sensitized samples was also investigated with microwave absorption and dielectric spectrum detection technology. After excited by a 355 nm fast-pulse laser, the photoelectron decay process of anionic-cationic dye sensitized sample is the fastest. This indicates that the affection of anionic-cationic dye aggregates to the photoelectron decay is the biggest, and the sensitization is more efficient.

作者： tao weidong Huzhou University

In The Philosophy of Chinese Moral Education:A History,the authors have deftly put together a complete history of a special dimension of Chinese philosophy ranging from the early Zhou dynasty to the end of the Republican period through the lens of moral education.A major merit of this book is that it presents readers with a holistic picture of the Chinese philosophical tradition by emphasizing moral *** in clear,concise language but well referenced and annotated,it is highly readable and informative for people interested in Chinese culture or education.

以生理机制上整体可能身体姿势、整体不可能身体姿势和碎片身体姿势作为材料,系统操纵两个角度差为零的身体姿势偏离其竖直状态的角度,对错误率和反应时进行线性拟合。结果发现:(1)整体可能身体姿势、整体不可能身体姿势的识别错误率和反应时与其偏离直立状态角度之间可以拟合显著的线性关系,而碎片身体姿势的识别错误率和反应时与其偏离直立状态角度之间无法拟合显著的线性关系;(2)整体身体姿势(可能身体姿势和不可能的身体姿势)识别均出现了显著的倒置效应,而碎片身体姿势识别未出现倒置效应。这些结果表明身体姿势识别倒置效应量的延续性依赖于整体布局加工。

近年来,随着微机电系统、显微医疗和组织工程等领域技术水平的快速发展,微操作技术引起了科研界和产业界的广泛关注,其对于未来的微纳技术的小型化、功能化和集成设备的制造有着至关重要的作用。利用飞秒激光双光子聚合技术加工的微结构,其尺寸处于微观尺度,质地较脆、黏着力大、尺度效应显著,且微结构所受到的表面力逐渐取代重力起主导作用,以上因素进一步增加了微操作的难度。因此,一种基于毛细作用的玻璃毛细管吞吐微结构的微操作装置被提出,利用毛细力将微结构拾取和移动,再将不同的微结构装配在一起。该方法不仅能将微型原件进行组装,而且能将不同材料、不同特性的微型器件组装在一起,形成复杂的混合微结构。

Two novel Fe(Ⅱ) diimine complexes have been synthesized. In combination with MAO, they generate active catalytic systems that oligomerize ethylene with both high catalytic activity and high selectivity for a-olefins. The effects of substituents on the aryl ring, reaction temperatures and molar ratios of Al/Fe on catalytic activity and product distribution are studied.
