Spectroscopic Investigations of Pattern Formation and Chemically Heterogeneous Surfaces using Sum Frequency Generation Imaging Microscopy

化学系化学结构、动力学和机制项目A （CSDM-A）支持休斯顿大学的Steven Baldelli教授的一个项目，该项目将使用一种技术在分子水平上提供液体和固体之间边界的图像，帮助我们了解液体是如何湿润表面的。虽然液体润湿表面的研究已经进行了很多年，但这个过程还没有在分子水平上得到理解。这种新型成像技术的使用将为了解液固边界提供基础，这将影响催化、材料化学、粘附和基础表面科学等领域。除了大学研究人员外，该项目还将包括高中生。本研究将使用表面和频率生成（SFG）成像来提供非均质表面液体润湿的空间和光谱信息。这些研究的目标是揭示依赖于界面性质的过程的分子基础。

With this new award, the Chemical Structure, Dynamics and Mechanisms Program A (CSDM-A) of the Division of Chemistry supports Professor Steven Baldelli of University of Houston in a project that will use a technique to provide images of the boundaries between liquids and solids at the molecular level, helping us to learn how liquids wet surfaces. Although wetting of surfaces by liquids has been studied for many years, the process is not understood at the molecular level. The use of this novel imaging technique will provide the basis for a fundamental understanding of liquid-solid boundaries that will impact areas including catalysis, materials chemistry, adhesion, and basic surface science. In addition to university researchers, the project will include high school students.This research will use surface sum frequency generation (SFG) imaging to provide spatial and spectroscopic information on liquid wetting of a heterogeneous surface. The goal of these investigations is to uncover the molecular basis of processes that rely on interfacial properties.
