摘要：The key to develop high specific energy rechargeable batteries is development of new electrode *** existing electrode materials still have many problems:the shuttle effect and poor conductivity of the sulfur cathode,the inevitable volume expansion of the silicon anode and the lithium dendrite of the lithium metal anode that cause short circuits,***,as active electrical materials,conductive additives and electrode bodies,can play multiple roles in electrode *** interestingly,nanofibers can be functionalized to obtain better controllable properties(i.e.,electrolyte affinity,pore size distribution and surface electronic structure),thereby further enhancing electrochemical *** this article,the latest research progress in electrode design based on nanofibers is reviewed,including processing methods,structure,morphology and electrochemical *** key problems affecting the electrochemical performance of the electrode are also discussed,such as the preparation process,atomic structure,electrical conductivity,surface area and pore distribution of nanofibers,to provide reference points for nanofibers in excellent electrode design.

摘要：提出了通过综合习题帮助学生高效学习、系统总结以及综合运用自由基聚合知识,提高学生知识综合运用能力、知识探究能力、知识建构能力、知识迁移能力、提出问题的能力、解决问题能力,以及提高批判性思维及查阅文献意识的想法。基于该想法,设计了一道涵盖自由基聚合各主要问题的综合习题,并将其设计成小组作业,运用于高分子化学教学实践。创新了高分子化学习题形式,拓展了高分子化学作业功能,开拓了学生思路,取得了良好效果。

摘要：当今国际间竞争相当于科学技术、创新人才和国民科学素质的竞争。提高大学生科学思维能力,是提高我国公众科学素质的整体水平的关键,直接影响到我国未来的科技发展水平和实力。为了加强科学思维能力的培养,本文以大学热分析实验教学为例,通过提出问题、引导学生寻求解决方案并自主设计实验条件自由探索科学问题,经过独立思考和集体讨论得出相关结论,在此过程中培养学生的科学思维能力。
