项目摘要
This research project, supported by the Analytical and Surface Chemistry Program, focuses on the study of fundamentals of reactive collisions and soft-landing of polyatomic ions at surfaces. Professor Cooks and his students at Purdue University will contrast soft-landed ions at self-assembled monolayers with landing into vacuum-compatible liquid films. The functional groups available for reaction with impinging polyatomic ions at both of these surfaces will be varied to control the properties of the reaction products produced by these collisions. New multi-quadrupole instrumentation will be built and used in conjunction with existing multi-sector mass spectrometry instrumentation in pursuing this work. This project will provide a strong educational experience for students in the areas of mass spectrometry and surface science. The nature of chemical reactions that occur at surfaces involving projected polyatomic ion reactants remains poorly understood. Professor Cooks and his students at Purdue University will study the chemical reactions occurring between these polyatomic ions and a range of surfaces that exhibit diverse chemical properties. The long-term objective of this work is to develop new methods for the characterization of chemical reactions that occur at surfaces and to produce surfaces that have desired chemical features. The results of this work will have technological value in applications that depend on having surfaces with controlled chemical and physical properties.
该研究项目由分析和表面化学计划支持,重点研究多原子离子在表面的反应碰撞和软着陆的基本原理。 普渡大学的Cooks教授和他的学生们将把软着陆的离子在自组装单分子膜上与着陆到真空兼容的液体膜上进行对比。 在这两个表面上可用于与撞击的多原子离子反应的官能团将被改变以控制由这些碰撞产生的反应产物的性质。 将建造新的多四极杆仪器,并与现有的多部门质谱仪器一起使用,以开展这项工作。 该项目将为质谱和表面科学领域的学生提供丰富的教育经验。 在涉及投射的多原子离子反应物的表面发生的化学反应的性质仍然知之甚少。 普渡大学的Cooks教授和他的学生将研究这些多原子离子与一系列具有不同化学性质的表面之间发生的化学反应。 这项工作的长期目标是开发表征表面发生的化学反应的新方法,并产生具有所需化学特征的表面。 这项工作的结果将在依赖于具有受控化学和物理性质的表面的应用中具有技术价值。
