Metal oxide charge transport materials are preferable for realizing long-term stable and potentially low-cost perovskite solar cells(PSCs).However,due to some technical difficulties(e.g.,intricate fabrication protocols,high-temperature heating process,incompatible solvents,etc.),it is still challenging to achieve efficient and reliable all-metal-oxide-based ***,we developed efficient inverted PSCs(IPSCs)based on solution-processed nickel oxide(NiO_(x))and tin oxide(SnO_(2))nanoparticles,working as hole and electron transport materials respectively,enabling a fast and balanced charge transfer for photogenerated charge *** further understanding and optimizing the perovskite/metal oxide interfaces,we have realized an outstanding power conversion efficiency(PCE)of 23.5%(the bandgap of the perovskite is 1.62 eV),which is the highest efficiency among IPSCs based on all-metal-oxide charge transport *** to these stable metal oxides and improved interface properties,ambient stability(retaining 95%of initial PCE after 1 month),thermal stability(retaining 80%of initial PCE after 2 weeks)and light stability(retaining 90%of initial PCE after 1000 hours aging)of resultant devices are enhanced *** addition,owing to the low-temperature fabrication procedures of the entire device,we have obtained a PCE of over 21%for flexible IPSCs with enhanced operational stability.

中国山水画中所蕴含的空间意识不仅是中国传统绘画艺术所秉承的时空观的直接体现,也是中国哲学的自然观在艺术领域中的直观体现。山水画把作为造化的自然和具有创造性的心灵结合在一起,通过水墨的方式构造一种虚境,而且使得空间节奏化、音乐化了。山水画为达到这种表现而使用的方法是“以大观小”“三远法”和空间的诗化。但是近代以来,传统山水画的价值及空间技法受到了挑战。傅抱石对于传统山水画既有继承又有创新,但他把写实主义作为山水画的基础,并且用近代的透视法和比例关系来解释传统技法,尚存在诸多商榷之处。

COF-based quasi-solid polymer electrolytes for high-performance zinc-ion batteries

中国化学会第十届全国无机化学学术会议

The precisely controlled polymerization of diene and styrene by using rare-earth metal catalysts will be reported. The pincer-type ligands stabilized rare-earth metal complexes catalyse the polymerizations of dienes to give highly cis-1,4 regulated rubber materials, while those attached by CGC-type of ligands provide 3,4-regularity for isoprene polymerization. The polymerization of styrene with extremely high syndioselectivity and catalytic activity have been achieved by using with almost the whole period of rare-earth metals based catalysts. The DFT simulation reveals that the ligand contributes to lower the LUMO energy of the active species, thus the activation energy is reduced and the catalytic activity increases. The electron donating side arm of the ligand, on the other hand, may increase the electron density of the active species, therefore, increase its durability to the polar monomers such as methoxyl and methysilyl styrenes, leading to, for the first time, highly active and syndioselective polymerization of these polar styrenes, to give functional polystyrenes. Based on this, the copolymerization of ethylene with polar styrenes are achieved. The position of the substituted polar group influence the coordination mode of the polar styrene to the active metal center, and further the reaction ratios of the polar and nonpolar styrenes, to afford different microstructure copolymer products.

绘画形式要素若要获得自身的表现,必须依托秩序化的平面,并透过单纯简约、平面整体的秩序去感知独特的形式“意味”,从而增强了绘画艺术中的平面秩序美。平面秩序离不开概括、凝炼、简化的形式手段,这些都有待于对客观物象的整体把握和概括的能力,即在客观物象的自然形态关系上组织构建成新的主观平面视觉形象。

提出了一种基于改进决策树的导航系统故障诊断方法。该方法首先将导航数据的初始属性按照信息增益率进行排序,然后利用神经网络对初始属性进行裁剪处理,最后用裁剪后的属性建立最小决策树,并建立分类规则。与传统的决策树分类算法相比,此方法通过利用信息增益筛选属性,直接生成最小规模决策树,避免了决策树的剪枝处理过程。实验表明,此方法与传统决策树算法相比,时间开销更小,诊断精度也有所提高。
