AbstractCHE-0415979Beebe/DelawareThis research project, carried out in collaboration between Professors Beebe and Teplyakov in the Department of Chemistry at the University of Delaware, uses nanopits in graphite surfaces to template the growth of silicon oxide nanostructures. These "molecule corral" templates can be formed in a controlled fashion on the graphite substrate, and are used to controllably synthesize a range of silicon oxide nanoparticles, whose surface modification chemistry is then systematically studied. Information from this work helps to design process chemistries for the synthesis of nanomaterials with promising applications in electronic devices and sensor systems. With the support of the Analytical and Surface Chemistry Program, Professors Beebe and Teplyakov at the University of Delaware are examining methods for controllably synthesizing silicon oxide nanoparticles of various sizes, shapes, and size distributions. Using "molecular corrals" developed in Beebe's laboratory as templates, a wide range of controlled nanomaterials can be produced. The surface chemistry of these silica nanomaterials is then examined in this research.

该研究项目由特拉华大学化学系的Beebe教授和Teplyakov教授合作开展，利用石墨表面的纳米粒子来模板氧化硅纳米结构的生长。这些“分子围栏”模板可以在石墨衬底上以可控的方式形成，并用于可控地合成一系列氧化硅纳米颗粒，然后系统地研究其表面修饰化学。这项工作的信息有助于设计纳米材料合成的过程化学，这些纳米材料在电子设备和传感器系统中有很好的应用。在分析和表面化学项目的支持下，特拉华大学的Beebe教授和Teplyakov教授正在研究可控制地合成各种尺寸、形状和尺寸分布的氧化硅纳米颗粒的方法。使用Beebe实验室开发的“分子围栏”作为模板，可以生产出各种可控的纳米材料。研究了这些二氧化硅纳米材料的表面化学性质。
