Organic molecules are attractive electrode materials for rechargeable batteries owing to their sustainability,low cost,and light weight.In this work,we report a new organic anode,a perimidin derivative 1,3,5-tri(1 H-perimidin-2-yl)-benzene (TPB),for lithium-ion batteries.The TPB structure contains multiple redox centers including π-conjugated benzene ring,C=N,and -NH groups and delivers a high reversible specific capacity of 300 mAh/g at 50 mA/g under a six-electron redox reaction.Moreover,TPB exhibits excellent rate capability and long-term cyclability with 98.1％ capacity retention over 1500 cycles at 1000 mA/g.The results may open new opportunities for the development of low-cost and long-lifespan lithium-ion batteries.

数据中心的供配电系统作为保障通信服务系统运行工作的基础,是建设数据中心的重点关注问题。高压直流供电系统在通信领域的应用逐渐广泛,但产业链及供电系统各环节技术设备还不成熟,存在安全可靠性、节能环保性方面的缺陷,论文讨论了新技术与直流供电系统结合的可行方案,并针对相关问题进行了具体解决方案的设计。在讨论高压直流供电技术性能优势和可行性的基础上,详细阐述了数据中心高压直流供电系统的各组成环节及系统工作原
禾本科植物(小麦,水稻等)是当今世界上种植面积最广泛、总产量最高的农作物,有着极其重要的经济地位。随着世界人口的膨胀,人们对植物产量的要求也在不断提高。生物技术和农业科学的发展,催生了许多优良品种。但是植物的高产量(伴随高茎秆)与植物茎秆的抵抗倒伏性能始终是一对矛盾。而植物茎秆的屈曲是其倒伏的主要力学表现。本文以中空植物茎秆为研究对象,利用正交各向异性力学理论,建立纵向加肋多层圆柱壳模型,应用AB
