氧化还原功能纤维的研究 Ⅷ．含正丙胺基吸附剂与Au~（3＋）的氧化还原反应机理

通过元素分析、红外光谱分析、光电子能谱分析以及扫描电子显微镜分析等手段，证实含正丙胺基吸附剂与Ａｕ３＋的氧化还原反应过程中，氮原子邻近的羟基碳或Ｃ－Ｈ键被氧化，而氮原子并未参与氧化还原反应；吸附态Ａｕ（３＋）最终部分被还原成单质金；在非水介质中吸附在吸附剂上的金聚集成颗粒状。

4，4＇－二苯醚二甲酸改性PET的热性能研究

采用示差扫描量热和热重分析的方法对合成的不同４，４＇－二苯醚二甲酸（ＯＢＢＡ）含量的共聚酯的热性能进行了研究。结果发现共聚酯的熔点和热结晶温度与ＰＥＴ相比有所降低；而冷结晶温度则升高。随着ＯＢＢＡ添加量的增加，在恒温热重分析中热失重速率常数减小；在升温热重分析中，热失重活化能则增加。所有的实验结果皆表明，芳族醚键的引入对提高共聚酯的热性能有重要作用。     

An antiphishing strategy based on visual similarity assessment

The authors' proposed antiphishing strategy uses visual characteristics to identify potential phishing sites and measure suspicious pages similarity to actual sites registered with the system. The first of two sequential processes in the SiteWatcher system runs on local email servers and monitors emails for keywords and suspicious URLs. The second process then compares the potential phishing pages against actual pages and assesses visual similarities between them in terms of key regions, page layouts, and overall styles. The approach is designed to be part of an enterprise antiphishing solution.

Growth and optical property of zinc oxide thornballs

A new microstructure, thornball, of zinc oxide (ZnO) was synthesized by a very simple solid vapor deposition process under lead oxide (PbO) atmosphere. The microthornballs consist of numerous needles, which extend outwards in all directions symmetrically. They have dimensions of 120 μm in diameter, while the average diameter of the needles is about 100-200 nm. The needles on the balls grow along the 〈0 0 0 1〉 orientation and have gradient compositions along radial. Control experiments proved that PbO played an important role in the growth. Additionally, photoluminescence property was observed and provided the evidence that PbO did not deteriorate the optical properties of ZnO thornballs. This kind of microstructures has potential applications in the field of photochemical catalysis.
