The Analytical and Surface Chemistry (ASC) program will support the research project of Prof. Steven Sibener of the Department of Chemistry at the University of Chicago. Prof. Sibener and his students will elucidate how the reactivity of adsorbed species on a surface is influenced by the local structure and ensemble configuration of adsorbates. Prof. Sibener and his students will couple variable-temperature UHV-STM instruments that have been developed in the Sibener laboratory with supersonic and hypersonic molecular beams in order to systematically explore heterogeneous reaction mechanisms at the molecular level. This ambitious program will significantly advance our understanding of interfacial and molecular reactivity, generating fundamental knowledge for refining our understanding of mechanistic chemistry. The project will provide excellent training opportunities to undergraduate students, graduate students and postdoctoral fellows who wish to develop greater understanding of heterogeneous chemical systems. Prof. Sibener and his students will promote the understanding of fundamental chemistry in K-12 students and focus their efforts on students from under represented groups.

分析和表面化学（ASC）计划将支持芝加哥大学化学系Steven Sibener教授的研究项目。Sibener教授和他的学生将阐明表面上吸附物种的反应性如何受到吸附物的局部结构和系综构型的影响。Sibener教授和他的学生将把Sibener实验室开发的变温UHV-STM仪器与超音速和高超音速分子束相结合，以便系统地探索分子水平上的非均相反应机制。这个雄心勃勃的计划将大大提高我们对界面和分子反应性的理解，为完善我们对机械化学的理解提供基础知识。该项目将提供良好的培训机会，本科生，研究生和博士后研究员谁希望发展更多的了解非均相化学系统。Sibener教授和他的学生将促进K-12学生对基础化学的理解，并将精力集中在来自代表性不足的群体的学生身上。
