项目摘要

AbstractCHE-0413611Maciel/Colorado StateWith the support of the Analytical and Surface Chemistry Program, Professors Maciel, Grainger, and Parkinson at Colorado State University are collaborating to develop the use of solid state NMR methods to provide detailed NMR spectroscopic information about highly ordered, low surface area single crystal surface science samples. This research project is developing the Magic Angle Hopping probe for solid state NMR studies developed by Maciel to studies of the surface chemistry of stacked thin film silica or gold wafer sample substrates. A combination of instrument method development, and examination of important questions in molecular self assembly at surfaces, is the focus of this research. The collaboration brings together expertise in solid state NMR, self-assembled monolayers, and scanning probe microscopic characterization of surfaces to attack this important problem.The ability to carry out high resolution NMR studies of surface chemical processes on well characterized substrates would revolutionize surface science studies. The work of this collaborative project at the University of Colorado focuses on the design and implementation of state of the art solid state NMR methods to probe low surface area highly ordered samples. Drawing on expertise in solid state NMR methods, surface chemistry of self-assembled monolayers, and surface characterization by scanned probe microscopy, the collaborators are developing new approaches to bridge the information gap between surface science and high surface area materials characterization.

Maciel/科罗拉多州在分析和表面化学项目的支持下，科罗拉多州立大学的Maciel、Grainger和Parkinson教授正在合作开发固态NMR方法的应用，以提供有关高度有序、低表面积单晶表面科学样品的详细NMR光谱信息。该研究项目正在开发由Maciel开发的用于固态NMR研究的Magic Angle Hopping探针，用于研究堆叠薄膜二氧化硅或金晶片样品基底的表面化学。结合仪器方法的发展，并检查在表面的分子自组装的重要问题，是本研究的重点。此次合作汇集了固体核磁共振、自组装单分子膜和扫描探针表面微观表征方面的专业知识，以解决这一重要问题。在表征良好的基质上进行表面化学过程的高分辨率核磁共振研究的能力将彻底改变表面科学研究。这个合作项目在科罗拉多大学的工作重点是设计和实施最先进的固态NMR方法来探测低表面积高度有序的样品。利用固态NMR方法，自组装单分子层的表面化学和扫描探针显微镜的表面表征方面的专业知识，合作者正在开发新的方法来弥合表面科学和高表面积材料表征之间的信息差距。
