Flow-Enabled Ordered Nanocrystal Assemblies

1332780LIN这个项目的目标是开发一种简单但健壮的流动使能自组装(FESA)方法，通过使用带有固定上平板和移动下衬底的两个平行板几何结构，在由功能纳米晶体(即量子点和量子棒)和两嵌段共聚物组成的大面积上重复地创建高度有序的结构。将合成尺寸、形状和表面特征精确可控的发光纳米晶。随后，通过微观尺度上的FESA和纳米尺度上的自发自组装的协同作用，将获得大面积由纳米晶体组成的层次化有序结构。将开发该过程的理论模型，并将其用作优化该过程的指导。在这个项目中产生的知识可能导致有趣的纳米设备和材料的创造和发展，用于微电子学、光电子学、传感器和生物技术。除了为本科生和研究生提供研究培训外，该项目还将为高中教师提供暑期研究机会。

1332780LinThe objective of this project is to develop a simple, yet robust, flow-enabled self-assembly (FESA) method through the use of two-parallel-plate geometry with a fixed upper plate and a moving lower substrate to reproducibly create highly ordered structures over large areas composed of functional nanocrystals (i.e., quantum dots and quantum rods) and diblock copolymers. Luminescent nanocrystals with precisely controllable size, shape, and surface characteristics will be synthesized. Subsequently, hierarchically ordered structures composed of nanocrystals over large areas will be obtained via the synergy between FESA at the microscopic scale and spontaneous self-assembly at the nanoscale. A theoretical model of the process will be developed and used as a guide for optimizing the process. Knowledge generated in this project may lead to the creation and development of intriguing nanodevices and materials for use in microelectronics, optoelectronics, sensors, and biotechnology. The project will also offer summer research opportunities for high school teachers in addition to providing research training to undergraduate and graduate students.
