Four Ru(Ⅱ)/Ir(Ⅲ) metalloligands have been designed and synthesized from polypyridine and bibenzimidazole (BiBzIm) organic ligands, and show strong visible light absorption via metal-to-ligand charge transfer (MLCT) transitions.Nd/Yb(Ⅲ) lanthanide complexes were further assembled from the Ru(Ⅱ)/Ir(Ⅲ) metalloligands, and Ln(Ⅲ)-centered NIR emissions can be efficiently sensitized by 3MLCT states of the metalloligands in visible-light region.

本文通过机械振动课程中线性振动与非线性振动幅频特性的对比分析，论述了MATLAB在实践教学应用中的便捷性和实用性。在机械振动课程的教学过程中，教师可多鼓励学生将一些课后习题利用MATLAB软件来完成，锻炼学生通过编写小编程来解决机械振动问题的能力，通过计算机的辅助分析，达到提高其力学实践能力与培养科研兴趣的目的。
针对二维无限大轴对称结构，在半径为μm量级(近似点热源)的脉冲激光面热源加热条件下，建立了合金构件的温度场随时间与空间变化的加热理论模型，得到温度场分布的理论解。利用ABAQUS对于对应模型进行二维、三维有限元建模。在一个瞬态脉冲载荷加热下，重点对比分析了理论解与有限元得出的温度场，在构件表面与厚度方向的分布规律及加热点中心处温度随时间变化规律，同时得出了多次脉冲栽荷加热冷却与等效加热的对比结果，
主要研究了块状纳米多孔铜及纳米多孔铜与环氧树脂复合材料的制备及其力学性能，研究了腐蚀温度、合金中铜的原子比、块体宏观尺寸和腐蚀时间对纳米多孔铜的微观形貌的影响，以及间接地对材料的力学性能的影响。块状纳米多孔铜通过常规去合金化腐蚀方法制备而成。有些纳米多孔铜展示出双模式结构，而有些纳米多孔铜展示出单模式结构。力学性能主要通过压缩实验获得。
