项目摘要
In this CAREER award, funded by the Chemical Structure, Dynamics and Mechanisms (CSDM-A) Program of the Division of Chemistry, Professor Sean A. Garrett-Roe of the University of Pittsburgh and his post-doctoral, graduate and undergraduate student colleagues are conducting experimental studies of the unique ways that substances behave when they are dissolved in ionic liquids. Ionic liquids are a unique class of materials, essentially a salt that is molten at very low temperatures. These ionic liquids show promise as replacements for organic solvents, but their molecular behavior remains poorly understood. These studies help to inform scientists who are using ionic liquids, and may eventually lead to industrial solvents with improved properties. Post-doctoral, graduate and undergraduate students working on this project receive world-class training in ultrafast laser science, while working on a compelling chemical problem with real-world impact. Part of this CAREER program is also focused on a number of education projects, including the development of guided-inquiry curriculum materials and actual hands-on research to introduce undergraduates to an authentic research experience in the first two years of College. Prof. Sean A. Garrett-Roe and his research group uses ultrafast, two-dimensional infrared spectroscopy to probe the transient structures that are present in interactions between solute molecules and ionic liquid solvents. The specific studies include: (1) carbon dioxide uptake in ionic liquids; (2) partitioning between nanoscopic domains of organic and organic azides; (3) the measurement of solvent friction in intramolecular proton transfer reactions. The young researchers working on this project receive excellent technical training in laser science and cutting edge optical methods. In the educational projects of this CAREER award, Prof. Garrett-Roe and his students develop curriculum materials on the structure and dynamics of simple liquids for incorporation into the undergraduate (guided inquiry) curriculum, a structured way of introducing early-career undergraduates to scientific research. Prof. Garrett-Roe also participates in the University of Pittsburgh's FER (First Experiences in Research) Program, which recruits from first- and second-year undergraduates.
匹兹堡大学的Sean A. Garrett-Roe教授和他的博士后、研究生和本科生同事正在进行实验研究,研究物质在离子液体中溶解时的独特行为方式。该奖项由化学系化学结构、动力学和机制(CSDM-A)项目资助。离子液体是一类独特的材料,本质上是一种在极低温度下熔化的盐。这些离子液体有望取代有机溶剂,但人们对它们的分子行为仍知之甚少。这些研究有助于告知正在使用离子液体的科学家,并可能最终导致性能改善的工业溶剂。从事该项目的博士后、研究生和本科生将在超快激光科学方面接受世界一流的培训,同时研究具有现实影响的引人注目的化学问题。这个职业项目的一部分也集中在一些教育项目上,包括指导探究课程材料的开发和实际动手研究,在大学的头两年向本科生介绍真实的研究经验。Sean A. Garrett-Roe教授和他的研究小组使用超快二维红外光谱来探测溶质分子和离子液体溶剂之间相互作用中存在的瞬态结构。具体研究包括:(1)离子液体中二氧化碳的吸收;(2)有机叠氮化物和有机叠氮化物的纳米结构域划分;(3)分子内质子转移反应中溶剂摩擦的测量。从事该项目的年轻研究人员在激光科学和尖端光学方法方面接受了良好的技术培训。在CAREER奖的教育项目中,Garrett-Roe教授和他的学生开发了关于简单液体的结构和动力学的课程材料,并将其纳入本科(引导探究)课程,这是一种结构化的方式,将早期职业生涯的本科生引入科学研究。Garrett-Roe教授还参加了匹兹堡大学的FER (First Experiences in Research)项目,该项目从一年级和二年级的本科生中招募。
