Carboxymethyl chitosan/poly（ethylene oxide）（CCTS/PEO） composite is firstly reported as a water soluble binder for the application of 5V LiNi0.5Mn1.5O4 cathode in Li-ion batteries. Both CCTS and PEO show a high electrochemical oxidation potential of above 5.0 V（vs. Li/Li＋）. The electrochemical performances of LiNi0.5Mn1.5O4（LNMO） cathodes with CCTS/PEO composite binders of different mass rates are investigated, it is found that LiNi0.5Mn1.5O4 cathode with an optimized CCTS/PEO（85/15, w/w） composite exhibits a slightly better cycling performance than that of polyvinylidene fluoride（PVDF）, retaining 81.4% capacity as compared with 79.8% for PVDF at 0.5C rate after 200 cycles. LNMO with PEO/CCTS（85/15,w/w） exhibited the better rate capability than that of PVDF. These results demonstrate that CCTS/PEO composite can be potentially used as a water-soluble binder for 5 V LNMO cathode.

材质是观念的载体,观念是人在实践中对事物主观与客观认识系统化的集合体。毋庸置疑,版画艺术的发展从最初就离不开对材质的追求与探索。人们对各版种的分类也正是依据不同版材所特有的物质属性而延展开来的。材质与观念是互为因果辩证关系的,当艺术家的观念指向发生转变时,工具材质与技艺自然也会随之更新与进步。相反,材质与技术的革新对观念的更替也会起到一定程度的推进作用。可见,材质的拓展与延伸对版画艺术发展有着极为重要的作用。在版画艺术的发展历程中,当某版种技术发展到一定程度不能满足艺术家的表现形式时,这种版材就会发生相应的更替,就像铜版雕刻曾取代了木刻.

协同过滤是推荐系统中最经典的方法之一,能够满足人们对个性化推荐任务的需求,但许多协同过滤算法在面对评分数据稀疏性问题时推荐效果不佳。为解决此问题,提出一种结合矩阵补全的宽度协同过滤推荐算法。先使用矩阵补全技术对用户项目评分矩阵进行补全,再利用补全后的矩阵对已评分的用户和项目分别寻找其近邻项,进而构造用户与项目的评分协同向量,最后使用宽度学习系统来构建用户项目与评分之间的复杂的非线性关系。在MovieLens和filmtrust数据集上对所提出算法的有效性进行检验。试验结果表明,与当前最先进的方法相比,该方法能够有效地缓解数据稀疏性问题,具有较低的计算复杂度,在一定程度上提升了推荐系统的性能。
