项目摘要
The Chair program focuses on understanding and designing atomic and electronic structures of embedded nano-structures, which are confined at dislocations and interfaces in crystalline solids, in order to enhance material performance beyond that of the idealized solid. In the proposed research program, Dr. Zhu plans to study formation dynamics and performance characteristics of embedded nano-structures by advancing in-situ electron microscopy techniques and further exploring her recent findings on reconstructed gold-oxide interfaces and dislocation-based nano-structures in magnesium. Research will be untaken in three themes. Theme1 will expand beyond the visualization capability of Dr. Zhu's current in-situ, electron microscope-based thermo-mechanical testing platform by adding new function such as monitoring crystallographic evolutions and estimating mechanical properties in a way that is comparable to macroscopic testing. Dr. Zhu will make use of the technique developed in Theme1 to overcome the characterization difficulties of embedded nano-structures and study linear (Theme2) and planar (Theme3) embedded nano-structures during formation, migration, and deformation processes. Theme2 will identify formation dynamics and deformation physics of dislocation-based nano-structures to develop advanced magnesium alloys. Theme3 will tune gold-rutile interfaces and interface-mediated mass migration processes to assemble high quality rutile nanowires. The outputs of the proposed research include: i). new characterization techniques that can resolve embedded nano-structures and their surrounding lattices; ii) the development of high-strength and high-ductile magnesium alloys and advanced oxide nanowires for biomolecule detection; iii) a theoretical framework that is capable of predicting defect-enhanced nano-structures and the corresponding material behaviors that they can produce. The results will be of great value to the key industries involved in aerospace, automotive, renewable energy industry. Students and researchers will be trained with the unique skillset, particularly reconfiguring electron microscopes and characterizing new nano-structures, for their further academic and career development.
椅子程序侧重于理解和设计嵌入式纳米结构的原子和电子结构,这些结构被限制在晶体固体中的位错和界面,以提高材料性能超越理想化固体。在拟议的研究计划中,朱博士计划通过推进原位电子显微镜技术研究嵌入式纳米结构的形成动力学和性能特征,并进一步探索她最近在镁中重建金氧化物界面和基于位错的纳米结构方面的发现。将在三个主题中进行研究。Theme 1将通过增加新功能,如监测晶体学演变和以与宏观测试相当的方式估计机械性能,扩展朱博士目前基于电子显微镜的原位热机械测试平台的可视化功能。朱博士将利用主题1中开发的技术来克服嵌入式纳米结构的表征困难,并研究线性(主题2)和平面(主题3)嵌入式纳米结构在形成,迁移和变形过程中的特性。主题2将确定位错为基础的纳米结构的形成动力学和变形物理,以开发先进的镁合金。主题3将调整金-金红石界面和界面介导的质量迁移过程,以组装高质量的金红石纳米线。拟议研究的产出包括:i)。新的表征技术,可以解决嵌入式纳米结构及其周围的晶格; ii)高强度和高韧性镁合金和先进的氧化物纳米线的生物分子检测的发展; iii)一个理论框架,能够预测缺陷增强纳米结构和相应的材料行为,他们可以产生。研究结果将对涉及航空航天、汽车、可再生能源等重点行业具有重要价值。学生和研究人员将接受独特技能的培训,特别是重新配置电子显微镜和表征新的纳米结构,以促进他们的进一步学术和职业发展。
