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

有了这个新的奖项，化学系的化学结构、动力学和机制计划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的边界图像，帮助我们了解液体如何润湿表面。尽管液体润湿表面的研究已经进行了很多年，但在分子水平上还不了解这一过程。这种新的成像技术的使用将为从根本上理解液-固界面提供基础，这些界面将影响催化、材料化学、附着力和基础表面科学等领域。除了大学研究人员，该项目还将包括高中生。这项研究将使用表面和频率产生(SFG)成像来提供关于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属性的过程的分子基础。

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.
