Lithium sulfur(Li-S)battery is a kind of burgeoning energy storage system with high energy ***,the electrolyte-soluble intermediate lithium polysulfides(Li PSs)undergo notorious shuttle effect,which seriously hinders the commercialization of Li-S ***,a unique VSe_(2)/V_(2)C heterostructure with local built-in electric field was rationally engineered from V_(2)C parent via a facile thermal selenization *** exquisitely synergizes the strong affinity of V_(2)C with the effective electrocatalytic activity of VSe_(2).More importantly,the local built-in electric field at the heterointerface can sufficiently promote the electron/ion transport ability and eventually boost the conversion kinetics of sulfur *** Li-S battery equipped with VSe_(2)/V_(2)C-CNTs-PP separator achieved an outstanding initial specific capacity of 1439.1 m A h g^(-1)with a high capacity retention of 73%after 100 cycles at0.1 *** impressively,a wonderful capacity of 571.6 ma h g^(-1)was effectively maintained after 600cycles at 2 C with a capacity decay rate of 0.07%.Even under a sulfur loading of 4.8 mg cm^(-2),areal capacity still can be up to 5.6 m A h cm^(-2).In-situ Raman tests explicitly illustrate the effectiveness of VSe_(2)/V_(2)C-CNTs modifier in restricting Li PSs *** with density functional theory calculations,the underlying mechanism of VSe_(2)/V_(2)C heterostructure for remedying Li PSs shuttling and conversion kinetics was *** strategy of constructing VSe_(2)/V_(2)C heterocatalyst in this work proposes a universal protocol to design metal selenide-based separator modifier for Li-S ***,it opens an efficient avenue for the separator engineering of Li-S batteries.

塞缪尔.亨廷顿的"文明冲突论"、弗朗西斯.福山的"历史终结论",以及约瑟夫.奈的"软实(权)力说"等均对冷战后美国对中东战略的确立、实施和调整产生了影响,他们学术思想中的政策相关性更构成布什政府对中东战略的重要学理依据。其中,亨廷顿与福山等人的学术理念对"布什主义"影响甚深;约瑟夫.奈则对布什政府修复"美国形象"、后布什政府重振国家实力等积极建言。在美国对中东战略陷入困境之际,亨廷顿等人的学术观念亦遇到现实的严峻挑战,且政府与学界都出现了调整与反思的迹象。探究这些重要的学理因素,旨在深度体认并预判美国对中东战略及其走势,反思美国的国际关系理论对中国学界强化研究"思维的主体性"所产生的销蚀力,为构建"和谐世界"提供坚实的学理支撑。

起步于欧卡兹集市和克尔白神庙的阿拉伯商人,遵奉《古兰经》和圣训的经济理念,在每年的朝觐商贸与海外贸易的实践中逐步形成了阿拉伯民族'经商、信教'的特有文化传统;清真寺和集市的空间并存,折射出集市上的经济活动要受到清真寺伊玛目所宣传的伊斯兰经济思想的规范和制约的现实存在;目前的伊斯兰经济文化也面临着如何生存与怎样才能更好发展等切实挑战。我们可借助伊斯兰教法创制的自我更新机制,从以下几个方面作努力,推动伊斯兰经济文化的进一步发展:探究利息理论在现实操作中的变通策略及实施办法、寻求寺院经济融入国家经济乃至全球经济一体化的实现路径并调动清真寺在伊斯兰经济文化发展中的积极作用。

全球化背景下的阿-伊世界面临身份危机,对其进行文化身份认同,既是为了应对和抵制西方文化霸权,也是为了增强阿-伊世界的凝聚力。在和平、发展与和谐共处等认同中尽快融入全球化的主流。在正视美国为主的西方霸权主义对全球认同的侵蚀、伊斯兰激进主义排他暴力对阿-伊文化认同的干扰的前提下,对阿-伊文化身份进行辨证、前瞻、多元和务实性重构是必要的。
