All-safe liquid-state lithium-ion batteries(ASLS-LIBs) is of great interest as they can potentially combine the safety of all-solid-state batteries with the high performance and low manufacturing cost of traditional liquid-state LIBs. However, the practical success of ASLS-LIBs is bottlenecked by the lack of advanced separator technology that can simultaneously realize high performances in puncturing-tolerability,fire-resistance, and importantly, wetting-capability with non-flammable liquid-electrolytes. Here, we propose a concept of inorganic in-situ separator(IISS) by hybrid-sol physical crosslinking directly onto the electrode surface to address the above challenges. Particularly, the hybrid-sol is designed with silica nanoparticles as the building block and poly(vinylidene difluoride) nanoparticles as the crosslinking agent. The critical factors for controlling the IISS microstructures and properties have been systematically investigated. The advantages of the IISS have been confirmed by its fast wetting with various fireresistant liquid-electrolytes, customizable thickness and porous structures, robust interface with planar or three-dimensional(3D)-structured electrodes, and importantly, unexpected self-adaptability against puncturing. Enabled by the above merits, a fire-resistant ASLS-LIB is successfully assembled and demonstrated with stable electrochemical performance. This sol-crosslinked IISS may open an avenue for the studies on the next-generation separator technology, cell assembling, solid electrolyte processing as well as non-flammable secondary batteries.

Qutrit is the natural extension of qubit in quantum information processing and has quite a few advantages that outperform qubit. In this paper, we investigate the feasibility of teleportation of an unknown qubit state, as well as an unknown qutrit state using a two-qutrit entangled pair. We show that by carefully constructing the measurement bases, both the qubit and the qutrit can be faithfully teleported from Alice to Bob with a two-qutrit maximally entangled state.

大学生返乡创业是推进乡村振兴战略、缓解大学生就业压力的重要途径。基于大学生返乡创业政策文本,通过构建政策工具、发展阶段、利益相关主体的三维框架进行政策评估。研究发现,大学生返乡创业已经吸引了政府的持续关注和高度重视,环境型和供给型政策工具使用过度,而需求型政策工具使用不足;政策措施主要关注初创阶段和成长阶段,较少涉及成熟阶段;政策注意力主要集中在返乡创业者、返乡创业企业等核心利益主体上,较少关注金融机构、高校等次要利益主体。基于此,建议深度优化政策工具整体结构,增加需求型政策供给;强化政策措施与返乡创业生命周期匹配度,加大成熟期政策支持力度;协调兼顾各个参与主体的利益,推动金融机构、高校等利益相关主体为大学生返乡创业提供支持。

With increasing awareness of sustainability, demands on optimized design of building shapes with a view to maximize its thermal performance have become stronger. Current research focuses more on building envelopes than shapes, and thermal comfort of building occupants has not been considered in maximizing thermal performance in building shape optimization. This paper attempts to develop an innovative ANN (artificial neural network)-exhaustive-listing method to optimize the building shapes and envelope physical properties in achieving maximum thermal performance as measured by both thermal load and comfort hour. After verified, the developed method is applied to four different building shapes in five different climate zones in China. It is found that the building shape needs to be treated separately to achieve sufficient accuracy of prediction of thermal performance and that the ANN is an accurate technique to develop models of discomfort hour with errors of less than 1.5%. It is also found that the optimal solutions favor the smallest window-to-external surface area with triple-layer low-E windows and insulation thickness of greater than 90 mm. The merit of the developed method is that it can rapidly reach the optimal solutions for most types of building shapes with more than two objective functions and large number of design variables.

Energy-efficient communication is an important requirement for mobile relay networks due to the limited battery power of user terminals. This paper considers energy-efficient relaying schemes through selection of mobile relays in cooperative cellular systems with asymmetric traffic. The total energy consumption per information bit of the battery-powered terminals,i.e.,the mobile station （MS） and the relay,is derived in theory. In the joint uplink and downlink relay selection （JUDRS） scheme we proposed,the relay which minimizes the total energy consumption is selected. Additionally,the energy-efficient cooperation regions are investigated,and the optimal relay location is found for cooperative cellular systems with asymmetric traffic. The results reveal that the MS-relay and the relay-base station （BS） channels have different influence over relay selection decisions for optimal energy-efficiency. Information theoretic analysis of the diversity-multiplexing tradeoff （DMT） demonstrates that the proposed scheme achieves full spatial diversity in the quantity of cooperating terminals in this network. Finally,numerical results further confirm a significant energy efficiency gain of the proposed algorithm comparing to the previous best worse channel selection and best harmonic mean selection algorithms.

为探索真空热处理与谷蛋白对肌原纤维蛋白(Myofibrillar Protein,MP)凝胶性能的影响,实验以罗非鱼MP为原料,以质构、持水、分子间作用力等为指标研究了真空热处理与谷蛋白添加对罗非鱼MP凝胶的影响。结果表明,在水浴条件下,加入0.7%的谷蛋白显著提高了MP的硬度、凝胶强度。微观结构结果表明谷蛋白使MP凝胶网络趋于平整,孔洞减小,有利于凝胶的形成。与水浴加热相比,经过一段式真空热处理1 h后,MP凝胶的内聚性、弹性、凝胶强度显著提高,真空热处理2 h后,MP凝胶的内聚性与凝胶强度进一步提高。另外,真空热处理和谷蛋白添加改善了MP凝胶的水分状态,T22固定水的含量下降,同时T22固定水与T23自由水的迁移受到限制,使凝胶内水分趋于稳定。分子间作用力结果显示,离子键与疏水相互作用增强,促进了MP的凝胶化。综上所述,真空加工和谷蛋白添加促使MP结构伸展,形成更加致密的三维凝胶网络。
