This Research Planning Grant project is in the broad area of materials chemistry and in the subfield of nanostructures. During the tenure of this eighteen-month standard grant, Professor Liu and her students at Wayne State University will conduct preliminary experiments designed to establish the feasibility of a research program in the fabrication and characterization of nanoscale materials. Their strategic approach involves the preparation of a variety of nanoparticle structures and patterns including dots, line, and two-dimensional islands with various shapes, followed by the characterization of these structures using force microscopy, particularly scanning tunneling microscopy (STM) and atomic force microscopy (AFM). Nanostructure synthesis will be based on both traditional self-assembly and Langmuir-Blodgett techniques to prepare templates as well as the direct electrosynthesis of nanostructures using the probe tips of the force microscopes. The ability to prepare nanometer-sized materials and to control the size and structures of these particles is of immense fundamental and technological importance. This Research Planning Grant project will lead to a research program in the fabrication and characterization of nanoscale materials with `size tunable` properties of importance to quantum physics and chemistry, new sub- micron electronic devices, and novel optoelectronic materials.

这个研究规划补助金项目是在材料化学的广泛领域和纳米结构的子领域。 在十八个月的标准资助期间，刘教授和她在韦恩州立大学的学生将进行初步实验，旨在建立一个研究计划的可行性，在纳米材料的制造和表征。 他们的战略方法包括制备各种纳米颗粒结构和图案，包括具有各种形状的点、线和二维岛，然后使用力显微镜，特别是扫描隧道显微镜（STM）和原子力显微镜（AFM）表征这些结构。 纳米结构合成将基于传统的自组装和Langmuir-Blodgett技术来制备模板，以及使用力显微镜的探针尖端直接电合成纳米结构。 制备纳米尺寸材料和控制这些颗粒的尺寸和结构的能力具有巨大的基础和技术重要性。 这项研究计划补助金项目将导致一个研究计划，在制造和表征纳米材料的“尺寸可调”的性质的重要性，量子物理和化学，新的亚微米电子器件，和新型光电材料。
