探索了由民用大丝束聚乙烯醇纤维(PVAF)试制活性碳纤维(ACF)的可能性,以开辟新的原料路线,降低产品成本。PVAF首先用脱水剂处理,脱水剂浓度为10%(质量),然后在200—300℃进行热处理,处理后的纤维再经预氧化和碳化活化转化为ACF,ACF的收率为37.7%,比表面积为1050m~2/g。此外,还探索了用O_3处理PVAF。用差热、热失重和红外等手段对产物进行了表征,推论了相应的反应机理。结果表明:经适当处理的PVAF可制得具有较好吸附性能的ACF。     

Surface modification of activated carbon fabric with ozone. Part 2: Thermal analysis with TGA-FTIR and DTA

Two samples of activated carbon fabrics (ACF) with very high surface area (>1300 to >1800 m²/g) fully ozonized in the part 1 of this study were analyzed by thermogravimetric analysis (TGA) coupled both with differential thermal analysis (DTA) and FT-IR spectroscopy (TGA-FTIR). The adsorbed water and the amount of oxygenated functional groups were determined. The ozonized ACF shows an exothermal decomposition at about 181–189°C which may be due at least in part to the decomposition of ozonide and/or peroxide groups. The TGA-FTIR has revealed that the main products released from the thermal decomposition are CO₂ followed by CO. Formic acid was detected only in correspondence to the exothermal transition at 181°C and was taken as a proof of the decomposition of secondary ozonides.     

The Power of the Inside Activist: Understanding Policy Change by Empowering the Advocacy Coalition Framework (ACF)

This article contributes to an understanding of policy change. Exploring a local land planning case, it investigates how an environmental advocacy coalition effectively challenged road and housing plans, with the result that an area was instead developed into a nature reserve. In the course of the article, the value and practical effectiveness of the Advocacy Coalition Framework (ACF) is examined and developed with the help of two central concepts—the “value network” and “inside activist”. The outcome of the case is explained by the powerful influence of a value network of ornithologists, with particular inside activists of that network playing important roles in presenting a challenge to development of the area. Instead of trying to build an abstract theory of the ACF, the article argues the need to develop the ACF as a framework, opening it up to insights from policy network and social constructionist research as well as from practical processes.     

活性炭纤维在脉冲放电水处理中的催化作用

为了探索脉冲放电水处理反应器与活性炭纤维联合应用的可行性以及活性炭纤维在脉冲放电过程中的作用,将活性炭纤维加入气液串联放电反应器中对模拟污染物甲基橙进行了联合降解,并对活性炭纤维在脉冲放电过程中表现出的催化作用进行了研究。实验结果表明:脉冲放电和活性炭纤维联合处理,大幅度提高了降解率近24%,说明活性炭纤维与脉冲放电联合具有协同效应;脉冲放电和吸附饱和活性炭纤维联合处理与单独脉冲放电处理相比降解率提高16.7%,活性炭纤维的催化作用显著;加入H2O2对OH的形成具有增强作用,同时提高了UV和O3的利用率而且还有利于活性炭纤维的再生。

Statistical Characterization of Open Failures in the Fine-Pitch COG Interconnection

Chip-on-glass (COG) interconnection using anisotropic conductive film (ACF) is susceptible to open failures. Open failures can be induced by the absence of conductive particles or an insufficient contact. Experimental results as well as statistical approaches were used to understand the conditions for open failures in COG bonding. The binomial distribution was used to predict the probability of the open failure due to the deficiency of conductive particles. The probability of an open failure decreased with increasing bump area and decreasing particle size. The bump height variation was also an important factor that affected the probability of the open failure together with the bump-to-electrode gap and the particle size. The variation in bump height should be minimized to avoid open failures in fine-pitch applications where a smaller particle size is required.
