NSF Young Investigator/Molecular Surface Analysis

这个国家科学基金青年研究员项目是在分析和表面化学的一般领域和表面分析的子领域。在这个为期五年的奖项的任期内，Levis教授和他的学生将开发质谱仪方法来研究吸附在表面上的复杂分子，并在这些薄膜中发现。主要涉及两个方面：(1)使用高温（1-10 eV）原子促进复杂吸附物从表面的非解离解吸，用于随后的质谱分析；(2)研究使用激光汽化生物分子用于高速DNA测序实验。该项目目标的成功实现将带来用于分子水平表面表征的新的质谱技术，快速DNA测序的新方法，以及薄膜分子固体异质外延沉积的新方法。此外，该NSF青年研究者奖应显著协助Levis教授建立一个重要的和富有成效的研究和研究培训计划。

This National Science Foundation Young Investigator project is in the general area of analytical and surface chemistry and in the subfield of surface analysis. During the tenure of this five-year award, Professor Levis and his students will develop mass spectroscopic methods for studying complex molecules adsorbed on surfaces and found in this films. Two primary thrusts are involved: (1) the use of hyperthermal (1-10 eV) atoms to promote nondissociative desorption of complex adsorbates from surfaces for subsequent mass spectroscopic analysis and (2) investigation of the use of laser vaporization of biological molecules for use in high speed DNA sequencing experiments. %%% The successful attainment of the goals of this project should give rise to new mass spectroscopic techniques for molecular-level surface characterization, novel approaches to rapid DNA sequencing, and new approaches to heteroepitaxial deposition of thin-film molecular solids. Additionally, this NSF Young Investigator Award should significantly assist Professor Levis in his establishing a vital and productive program of research and research training.
