摘要：Sub-1 nm nanowires(SNWs) can not only be processed like polymers due to their polymer-analogue properties but also show multifunctions owing to their well-manipulated compositions and structures. Rationally designed and engineered multicomponent heterostructure SNWs can further enhance their multifunction performance while it is very challenging to achieve such SNWs at ***, we synthesized Bi_(2)O_(3)-polyoxometalate heterostructure SNWs(PMB SNWs), and fabricated super-aligned PMB SNWs films(S-PMB SNWs films), which can serve as interlayers to efficiently suppress lithium polysulfide(LPS)shuttling, intrinsically promote the redox kinetics of the LPS conversion and substantially protect the Li anode. The lithium-sulfur(Li-S) battery with the S-PMB SNWs film as the interlayer showcases an ultralow capacity decay rate with 0.013% per cycle over 850 cycles. This study demonstrates the potential of heterostructure SNWs to improve the performance of Li-S batteries.

摘要：“实验动物学”是一门重要的基础课程,在医科院校普遍开展,其实践性和应用性兼具,主要培养学生的创新思维和实践能力。当前“实验动物学”实验课多采用验证性、重复性实验,难以达到培养复合型和创新型人才的目的。文章基于疾病动物模型构建的综合创新实验教学设计,探讨其具体实践及应用效果,以期为广大高校开展实验动物学实验课程改革提供借鉴和启发。
