摘要：锂硫电池是极具应用潜力的下一代高能量密度电池体系之一。然而,其充放电中间产物多硫化锂的“穿梭效应”不仅消耗大量电解液,还导致硫活性物质利用率低、循环寿命短,是锂硫电池产业化进程中的主要瓶颈之一。引入催化剂加速硫活性物质转化速率,减少多硫化锂在电解液中的累积浓度,是抑制穿梭效应的有效解决策略。高效的催化剂应具备丰富的催化活性位点,以确保高效吸附多硫化锂并加速其向不溶的充放电产物转化。本文制备出硫掺杂石墨烯表面原位负载的双金属硫化物NiCo_(2)S_(4)(NCS@SG)并将其作为催化剂应用于锂硫电池的中间层。相比于单金属硫化物(CoS),NiCo_(2)S_(4)催化剂具有多活性中心催化位点,可以更好地吸附多硫化锂并促进其向放电产物快速转化。应用上述中间层后,电池的充放电比容量、库仑效率和循环稳定性得到了明显提升。当硫的负载达到15.3 ***^(-2)时,经过50次循环后,具有NCS@SG中间层的电池获得了高达93.9%的容量保持率。上述结果表明,设计双金属基催化剂是优化锂硫电池催化剂活性和反应效率的重要方向。

摘要：the Information-Centric Networking(ICN) paradigm is proved to have the advantages of decreasing data delivery latency, enhancing user mobility, etc. However, current implementations of ICN require changing the infrastructure of Internet, which hinders its deployment and development. Meanwhile, Software Defined Networking(SDN) emerges as a viable solution to facilitate the deployment of new network paradigm without disrupting production traffic by decoupling the control plane from data forwarding plane. In this paper, the essential properties which reflect ICN working principles are summarized, and a framework called SDICN is designed in accordance to the SDN philosophy. The algorithmic frameworks of SDICN which can satisfy the essential properties are designed based on the programmability and virtualization functions of SDN. Based on Open Flow and data center technology, a prototype of SDICN is implemented. By comparing the performance with the CCNx, the SDICN is proved to be feasibility and availability.

摘要：A high detection efficiency calorimeter which is used to detect γ-rays with energies from 1 MeV up to 10 MeV as well as light charged particles has been proposed. Design of the geometry, results of the crystal tests and Monte Carlo simulations are presented in this paper. The simulation results confirm that the calorimeter can obtain high detection efficiency and good energy resolution with the current designed geometry. And the calorimeter is competent for the future External Target Facility （ETF） experiments.

摘要：正在研制的全海深载人舱及可调压载水舱等其他耐压壳体将采用马氏体镍钢材料制造。其中,18Ni(250)和18Ni(350)是两种备选的马氏体镍钢。在设计过程中,必须依据材料特性对耐压舱的寿命进行合理预报,以确保载人潜水器的使用安全。文中给出了18Ni(250)和18Ni(350)这两种材料的系列裂纹扩展率试验数据,并依据其中某一载荷比条件下的一组试验数据确定了用于寿命预报的统一裂纹扩展率模型参数。根据这些参数,对其他载荷比下的裂纹扩展率曲线进行了预报,并与试验结果进行了对比。对比结果表明了该模型及其参数预报方法对这两种材料的适用性。该项研究可为基于断裂力学的全海深载人舱和可调压载水舱的寿命预报提供基础。

摘要：Three "double-cable" conjugated polymers with thienopyrroledione-based backbone and perylene bisimide as side units were designed as electron acceptor for polymer-polymer solar cells. The polymers show broad absorption spectra and low-lying frontier energy levels due to both aromatic backbone and side units. The new double-cable polymers can be used as electron acceptor to combine with several electron donors, in which power conversion efficiencies above 3% could be achieved.
