采用化学气相沉积法(CVD)在多孔活性碳基体上制备掺硼金刚石涂层多孔电极。用扫描电子显微镜(SEM)法表征了金刚石膜的表面微观结构,采用循环伏安法和交流阻抗法研究了电极的电化学性质。结果表明,金刚石表面形态为球形,金刚石膜电极具有很宽的电势窗口,在酸性、中性和碱性3种介质中分别为4.4V、4.0V和3.0V。在铁氰化钾电解液中,金刚石膜电极表面在反应过程中始终保持良好的活性,在表面进行的电化学反应具有良好的准可逆性。     

河北兴隆中元古代硫化物黑烟囱金矿化的发现及其意义

现代海底黑烟囱具有金矿化的潜力,对于重新认识陆上硫化物的金成矿具有重要意义。本文对河北兴隆中元古代黑烟囱及烟囱内部金矿化进行了系统的研究,提供了喷流作用与金矿化关系的直接证据,矿石微区金最高含量达4560 μg/g。碳酸盐、石英和闪锌矿中流体包裹体的均一温度集中在100～200 ℃之间,代表黑烟囱形成的温度下限,也限定了金沉淀富集的温度范围,烟囱不同矿物和不同结构黄铁矿中含金量存在明显差异,金主要富集于后期形成的自形-半自形黄铁矿中,初步推测该区硫化物中金矿化发生于喷流作用后期,热液在烟囱及丘体内部持续活动,促进金的富集。

Highly stretchable,sensitive and wide linear responsive fabric-based strain sensors with a self-segregated carbon nanotube (CNT)/Polydimethylsiloxane (PDMS) coating

Flexible strain sensors have received increasing attention with the development of wearable electronic devices. However, integrating wide strain detection range, high sensitivity while maintaining relatively wide linear response range for such sensor system still remain a challenge. A fabric based flexible sensor (S-CNT/PDMS-F) was designed and fabricated, and the sensor can simultaneously achieve high sensitivity, wide linear response and strain detection range by combining self-segregated carbon nanotube (CNT)/polydimethylsiloxane (PDMS) composites and elastic medical bandage. It has been observed that this new sensor system can achieve a high sensitivity with a gauge factor of 615, a large linear responsive range of 0–100% strain (R² ?= ?0.993) and a wide strain detection range of ～ 200%, which is superior to almost all the reported CNT/PDMS flexible strain sensors. Compared to the similar fabric based strain sensor system deploying non self-segregated structure (C-CNT/PDMS-F), our S-CNT/PDMS-F demonstrates higher electrical conductivity and lower electrical percolation threshold and response time of 55 ?ms, as well as more stable and repeatable performance under cyclic loading conditions. The capability of the sensors in monitoring physiological activities and weight distribution has also been demonstrated.     

碳交易市场的利益博弈问题研究 ——基于层次分析法和夏普利值法视角

Through establishing Carbon Trading Platform (Carbon Trading Alliance) in the Carbon Trading Market, each participant can benefit more from the cooperation. But, the distributing mechanism of earnings of the market nowadays has a great influence on the development of Carbon Trading Platform. Based on that, the paper firstly utilize the traditional shapley value method to distribute the cooperative earnings of the Carbon Trading Market. Then, the risking factors taken by alliance members were brought in, and the weights of risks obtained trough the method of AHP, and risking coefficient was received. At last the existing results were corrected and the final distribution results were obtained. Finally, an example is used to verify the theory above. The research results show that the allocation system, taking risking factors into account, can improve the members'' enthusiasm to participate in the Carbon Trading Platform and promote the development and improvement of the Carbon Trading Platform and the market. Therefore, the results of this paper can provide a reference for policymakers of Carbon Trading Market.
