摘要：生物材料表面的物理性质,如拓扑结构,由于其易于加工和稳定的生物作用而受到广泛关注.虽然已有许多研究报道了材料表面拓扑结构与细胞的相互作用,但由于不同研究中使用的微结构和实验环境的多样性,生物材料表面不同微结构与细胞/组织行为之间的影响关系尚未得到很好的统一评价.在本研究中,我们设计了11种图案(三角形、矩形、圆形等),这些图案包含两种类型的形貌(微坑和微柱),这样一共得到22种表面拓扑结构.我们在体外和体内对这些微结构影响细胞和组织的生物作用进行了评估.我们的研究结果表明,由连续微坑形成的凹槽微结构促进细胞迁移效果相比其他微结构更强.其中,由三角形微坑组成的凹槽在体外对细胞迁移的促进作用最强.在大鼠皮下模型中,这种三角形微坑组成的凹槽结构减少了纤维组织的包封,促进了血管的形成.

摘要：空气稳定有机自由基的发现引起了人们对探究其在分子电子学和自旋电子学中应用的兴趣.这些自由基具有独特的开壳层电子结构,因而表现出特殊的电学特性.由于其较弱的旋轨耦合特性,也使得其成为自旋电子学的重要研究对象.此外,自由基还可以通过二聚、分子识别和机械互锁等分子间相互作用来构筑超分子器件.本文综述了空气稳定有机自由基在电子学及自旋电子学中的应用,通过详述其卓越的电磁性能来拓展启发分子设计的多样性.本综述还概述了超分子自由基的制备方法和相关性质的研究进展,拓宽了单分子研究的范围.此外,自由基介导的单分子反应是一个新兴的研究方向,本文也对该领域的未来发展方向进行了展望.通过阐明空气稳定有机自由基的应用潜力,本文将有望对分子电子学和自旋电子学的研究产生一定的指导意义.

摘要：传统双层材料的弯曲理论主要针对小变形、线弹性材料.这里我们研究了双层条的大变形弯曲,建立了一个描述双层条大变形弯曲的理论.理论中假设双层条由一个主动层和一个被动层组成,只有主动层会产生各向同性体积膨胀.分析表明我们的理论预测与有限元模拟符合较好,而在某些情况下会与传统理论预测有明显的差异.我们理论分析还表明,存在能使双层条得到最大曲率的最佳模量比及厚度比.我们的理论可促进软质双层条带材的设计,可广泛用于多个领域.

摘要：Landscape design for a green community should be favorable for the ambient ecological environment and for enhancement of both the local climate of a residential area and the environmental quality of life. This paper presents optimization methods for plant landscape design that take account of results of comparisons of noise reduction effects, heat island temperature decreases and effects on ventilation. These methods are based on different plant configurations and various luminous environments, such as exterior sunshine and shaded areas after the simulation of exterior luminous, acoustic and thermal environments of a residential area using the analytic software ECOTECT, CADNA/A, and PHEONICS. Three different types of residential buildings are simulated including a faculty apartment in the Xixi Campus of zhejiang University, the Huaqing Villa and the Gangwan Jiayuan faculty apartment of zhejiang University, china, based on green building design theory. In addition, the methods and process flow of landscape design of green residential areas are also described for the improvement of the exterior physical living environment.
