This National Science Foundation Young Investigator project is in the general area of analytical chemistry, with a specific focus on surface chemistry. During the five-year tenure of this award, Professor Hanley and his students will examine the reactions that occur when a high flux molecular ion beam impinges on a self-assembled monolayer. The fragments from this collision, when analyzed by mass spectrometry, yield valuable information about the structure of the parent ion. The state of the surface before and after the ion-surface collision will be probed using techniques such as x-ray photoelectron spectroscopy, infrared reflection absorption, and thermal desorption, and these experiments will allow the mechanisms of the surface induced dissociation process to be investigated. The use of these molecular ion beams for surface lithography of nanostructures and for plasma polymerization chemistry will also be explored during the course of this research project. This project should provide important insights into the mechanisms of molecular fragmentation occuring when molecular ions collide with a well-characterized surface. This approach, when used in conjunction with mass spectrometric detection, allows structurally similar molecules to be distinguished. Additionally, this award will enable Professor Hanley to further his overall professional development as a researcher and educator at the University of Illinois at Chicago.

这个国家科学基金青年研究员项目是在分析化学的一般领域，特别关注表面化学。在该奖项的五年任期内，Hanley教授和他的学生将研究当高通量分子离子束撞击自组装单层时发生的反应。这次碰撞产生的碎片经质谱分析后，得到了有关母体离子结构的宝贵信息。利用x射线光电子能谱、红外反射吸收和热脱附等技术探测离子表面碰撞前后的表面状态，这些实验将允许对表面诱导解离过程的机制进行研究。这些分子离子束在纳米结构表面光刻和等离子体聚合化学中的应用也将在本研究项目的过程中进行探索。这个项目应该提供重要的见解，分子分裂发生的机制，当分子离子碰撞一个表征良好的表面。这种方法，当与质谱检测结合使用时，可以区分结构相似的分子。此外，该奖项将使Hanley教授能够进一步发展他作为伊利诺伊大学芝加哥分校的研究人员和教育工作者的整体专业发展。
