Lithium metal is one of the most promising anodes for lithium batteries because of their high theoretical specific capacity and the low electrochemical potential. However, the commercialization of lithium metal anodes(LMAs) is facing significant obstacles, such as uncontrolled lithium dendrite growth and unstable solid electrolyte interface, leading to inferior Coulombic efficiency, unsatisfactory cycling stability and even serious safety issues. Introducing low-cost natural clay-based materials(NCBMs) in LMAs is deemed as one of the most effective methods to solve aforementioned issues. These NCBMs have received considerable attention for stabilizing LMAs due to their unique structure, large specific surface areas, abundant surface groups, high mechanical strength, excellent thermal stability, and environmental friendliness. Considering the rapidly growing research enthusiasm for this topic in the last several years, here, we review the recent progress on the application of NCBMs in stable and dendrite-free *** different structures and modification methods of natural clays are first summarized. In addition, the relationship between their modification methods and nano/microstructures, as well as their impact on the electrochemical properties of LMAs are systematically discussed. Finally, the current challenges and opportunities for application of NCBMs in stable LMAs are also proposed to facilitate their further development.

运用政策范式的理论框架,以政策文本分析为基础,梳理建国以来高等教育质量保障政策的话语谱系后发现:高等教育质量保障政策话语在不同历史阶段有明显的变化,历经数次政策范式转变。根据重大历史事件发生的时间及政策权威理念的演变,可将建国以来我国高等教育质量保障政策大致划分为四种范式:建制-规范化(1949-1984年)、改革-平衡化(1985-2000年)、项目-集成化(2001-2014年)和卓越-国际化即高等教育强国战略(2015年至今)。当下我国高等教育质量保障政策正呈现出政策问题趋于宏大、艰巨,政策目标走向统合、贡献趋附,政策工具寻求多元、组合的发展态势。相关方面有必要在提升政策调研水平、细化政策问题基础上促成政策目标可测评以及在现代化治理体系视野下选用更为强大的政策工具,从而使高等教育强国战略的政策范式落地。

鲜切蔬菜易受到食源致病菌的污染,然而传统的高温杀菌技术在鲜切蔬菜中的应用受到很大限制。通过研究热超声技术和茶多酚联合处理对鲜切冬瓜在不同温度储藏过程中沙门氏菌菌落数量的影响,以及自适应神经模糊推理系统(adaptive neuro-fuzzy inference system,ANFIS),构建了沙门氏菌菌落数量的预测模型。热超声和茶多酚联合处理显著减少了鲜切冬瓜中沙门氏菌的数量约2.20 lg CFU/g(P<0.05);在25、10和4℃温度下储藏时,不同温度下菌落数量变化趋势不同,但处理组的菌落数量均显著低于对照组(P<0.05),表明热超声和茶多酚联合处理是一种具有较大应用潜力的鲜切蔬菜保鲜技术。研究所建立的ANFIS模型,每个输入变量采用2个隶属函数,生成8个因果规则;采用gaussmf隶属函数的ANFIS模型对储藏过程中菌落数量的预测结果最好,其R^2大于0.99,均方根误差小于0.2。

针对正交补空间匹配追踪算法时间开销大、重构成功概率低的问题,提出了改进的正交补空间匹配追踪算法。该算法采用模糊阈值的方法进行支撑集原子选择,每次迭代自适应地选择观测矩阵中与当前重构残差相关性最大的若干个原子,减少重构迭代次数,加快了收敛速度;采用回溯法进行原子的二次筛选,将支撑集中错误选择的原子剔除,保证支撑集中原子的准确性。仿真实验结果表明,相比于正交补空间匹配追踪算法,改进算法成功重构所需时间更短,且重构成功概率更高。
