Relatively small amounts of In-doped Mo(O,S)2(IMS) catalysts(10%, 20%, and 30%) were deposited on cellulose nanofiber(CNF) by cross-linking them with functional groups of siloxane and epoxy to form CNF-IMS hybrid composites. The as-prepared hybrid composites were characterized and tested their performances toward the photo degradations of cationic(MB and Rh B) and anionic(MO) dyes. As indium was doped into Mo(O,S)2lattice to form solid-solution, the charge transfer and photocarrier separation during the catalytic reaction were simultaneously enhanced as probed with electrochemical impedance spectroscopy and photoluminescence measurements, respectively. To ensure the catalyst on CNF was well deposited and recyclable, the hybrid composite was evaluated with a reusability experiment to show the stability performance in degrading organic dyes. It was found the environmentally friendly CNF-IMS hybrid composite was relatively stable during the reusability experiment, indicating no catalyst powder was leached out during the photocatalytic reaction. The photoreaction mechanism was convinced by radical-scavenging experiments to show that hydroxyl and superoxide played essential roles for the organic dye degradations in visible-light illuminated conditions. The cross-linked organic/inorganic hybrid catalyst showed a prospective visible light active material not only to solve the environmental issue due to the leaching of nanoparticles but also to lower the post-treatment/recycling cost of photocatalyst in industrial application.

Effect of Temperature Dependence on Electrical Characterization of <i>p-n</i>GaN Diode Fabricated by RF Magnetron Sputtering

引用

Materials Sciences and Applications 2015年第9期6卷 809-817页

作者： Thi Tran Anh Tuan dong-hau kuo Cheng-Che Li Guan-Zhang Li Department of Materials Science and Engineering National Taiwan University of Science and Technology Taiwan School of Basic Sciences Tra Vinh University Tra Vinh Vietnam

The p-n junction GaN diodes were all fabricated by sputtering technique with cermet targets for p- and n-type GaN and metal targets for electrodes. The interface of these p-n junction GaN diodes examined by high-resolution transition electron microscopy was clear and distinguishable. Lattice images identified the complete dissolution of Mg into the Ga site. At the room temperature, the diode had the turn-on voltage of 2.2 V, the leakage current of 2.2 × 10–7 A, the breakdown voltage of –6 V, the barrier height of 0.56 eV, ideality factor of 5.0 by I (current)-V (voltage) test and 5.2 derived from the Cheungs’ method, and series resistance of 560 Ω. These electrical properties were investigated at different testing temperatures from room temperature to 200°C. The temperature dependence in the I-V characteristics of the p-n diodes can be successfully explained on the basis of thermionic-emission mode.

新型正渗透膜的制备对于推动膜分离技术的创新,解决水资源和环境问题,提高分离过程的效率和可持续性具有重要的意义.本研究以陶瓷膜为载体,采用热浸涂播种法制备了Zr-fum-MOF晶种,二次生长法制备了Zr-fum-MOF金属有机框架膜,进而探究了其在正渗透过程的脱盐性能,即不同运行条件下的水盐分离性能.结果表明,热浸涂法可以在陶瓷膜载体表面播种均匀的晶种层,在晶种液质量分数为0.1%的条件下热浸涂后,继而通过二次生长可以在表面形成共生良好、无晶间缺陷且厚度均匀的金属有机框架膜.以去离子水为进料液,汲取液为2 mol/L氯化钠的条件下,水通量达到9.86 L/(m^(2)·h),同时具有较低的比盐通量(0.43 g/L);相较之下,出现晶种团聚和针孔的Zr-fum-MOF-0.5%膜在相同运行条件下不能实现较好的水盐分离性能.将所制备的Zr-fum-MOF-0.1%膜应用于真实海水淡化也表现出较好的运行和结构稳定性.本研究所制备的陶瓷基金属有机框架膜在正渗透脱盐处理应用中显示出一定的潜力,为脱盐膜分离工艺提供了一定的技术参考和应用前景.

心力衰竭存在高发病率、高病死率的特征,寻求针对心力衰竭的有效治疗策略并进一步提升临床疗效一直是重要的研究方向。炎症失衡已被证明是心力衰竭的重要病理环节之一,与心功能障碍、心肌纤维化等不良事件呈正相关。近些年研究证实NOD样受体热蛋白结构域相关蛋白3(NOD-like receptor thermal protein domain-associated protein 3,NLRP3)炎症小体激活在不同因素诱导心力衰竭的炎症失衡环节中具有共性调控机制,并且部分中药及其有效成分能够显著抑制NLRP3炎症小体激活而改善心力衰竭。该文首先概述了NLRP3炎症小体的基本情况,然后总结了NLRP3炎症小体在不同因素诱导心力衰竭中的调控机制,最后介绍了近年来抑制NLRP3炎症小体而改善心力衰竭的中药及有效成分的研究进展,以期为中西医结合防治心力衰竭的创新药物研究提供参考。

Adjusting Sink Location to Reduce End-to-End Delay in Low-Duty-Cycle Wireless Sensor Networks

引用

Journal of Electronic Science and Technology 2015年第1期13卷 20-26页

作者： Yu-Yuan Lin kuo-Feng Ssu hau-Yu Chiang Institute of Computer and Communication Engineering National Cheng Kung University Department of Electrical Engineering National Cheng Kung University Data Systems Consulting Co. Ltd

Low-duty-cycle mechanisms can reduce the energy consumption significantly in wireless sensor networks（WSNs）. Sensors stay dormant most of the time to save their energy and wake up based on their needs. However, such a technique, while prolonging the network lifetime, sets excessive challenges for reducing the end-to-end（E2E） delay within the network. In this paper, the centralized cluster-based location finding（CCLF） algorithm is proposed to reduce the high latency in low-duty-cycle WSNs by finding a suitable position for the sink. The algorithm is mainly composed of three steps： a） the cluster construction, b） the fast look-up table（FLU-table） construction, and c） the sink location decision. The simulation results show that the performance of the CCLF algorithm is significantly similar to that of the optimal algorithm. Moreover, the CCLF algorithm requires less operation time compared with the optimal algorithm.
