Lithium-sulfur(Li–S) batteries are regarded as potential alternatives to lithium-ion batteries due to their extremely high theoretical energy density. Nevertheless, Li–S batteries still suffer from low coulombic efficiency,low sulfur utilization, and poor cycling life, which hinder their further applications. To obtain ideal Li–S cells,intensive work has been dedicated to improve the conductivity of the electrode, inhibiting the shuttle of lithium polysulfides, and promoting the redox of sulfur. Two-dimensional transition metal carbides, nitrides or carbonitrides, also known as MXenes, attracting significant research interest in Li–S batteries due to their high conductivity, abundant active sites, layered structure and adjustable surface chemistry. In this review, we summarize the partial etching methods of MXenes with different surface terminations, the role of MXenes in Li–S batteries and MXene-based composites designed for Li–S batteries based on interfacial chemistry and interlayer structure. In the end, we also propose the perspectives of MXenes for Li–S batteries.

Development of cheap,abundant and noblemetal-free materials as high efficient oxygen reduction electrocatalysts is crucial for future energy storage system. Here,one-dimensional（1D） MnO N-doped carbon nanofibers（MnO-NCNFs） were successfully developed by electrospinning combined with high temperature pyrolysis. The MnO-NCNFs exhibit promising electrochemical performance,methanol tolerance,and durability in alkaline medium. The outstanding electrocatalytic activity is mainly attributed to several *** of all,the uniform 1D fiber structure and the conductive network could facilitate the electron transport. Besides,the introduction of Mn into the precursor can catalyze the transformation of amorphous carbon to graphite carbon,while the improved graphitization means better conductivity,beneficial for the enhancement of catalytic activity for oxygen reduction reaction（ORR）. Furthermore,the porous structure and high surface area can effectively decrease the mass transport resistance and increase the exposed ORR active sites,thus improve utilization efficiency and raise the quantity of exposed ORR active sites. The synergistic effect of MnO and NCNFs matrix,which enhances charge transfer,adsorbent transport,and delivers efficiency in the electrolyte solution,ensures the high ORR performance of MnO-NCNFs.

针对当前中文语义依存分析中耗时长、准确率低的问题,提出了一种基于语句压缩进行中文语义依存分析的方法。在此方案中,首先通过开源工具CRF++训练得到特定的序列化标签压缩模型,通过此模型得到任意输入句子的主干信息,并为下一步提供候选集;其次,选取原句和压缩后句子中的词性、上下文等特征,使用条件随机场对其中的语义依存关系进行识别;最后进行谓语消歧和句子回溯。实验以Co NLL 2009公开任务中的公有语料作为数据集,与传统的直接使用基于图的语义依存分析方法相比,本方案的处理时间缩短了80%,精确率提高了3.48%,综合指标提高了2.11%。
