MRI: Acquisition of an Electron Paramagnetic Resonance (EPR) Spectrometer at the University of Vermont

该奖项由化学仪器(CRIF)计划、既定的激励竞争研究计划(EPSCoR)和重大研究仪器(MRI)计划共同资助。佛蒙特州大学农业学院的罗里·沃特曼教授和他的同事马修·利普塔克正在获取一台X波段电子顺磁共振(EPR)光谱仪。该光谱仪广泛应用于化学、生物、物理等领域。当磁场中的电子被微波照射时，该光谱仪可以观察到跃迁。获得的光谱提供了有关样品组成的有价值的信息。这些信息提供了对原子附近环境和系统性质的洞察。例如，该仪器用于快速筛选光伏设备的候选材料，以优化太阳能电池的效率。该仪器由佛蒙特州大学负责管理和管理。它为佛蒙特州以及新英格兰和纽约州北部的大片地区的研究人员提供服务。该仪器用于培训本科生和研究生的研究、讲座和实验室课程，为他们为现代劳动力做准备。这也影响了高中生，因为UVT已经制定了促进这种早期STEM教育互动的计划。该项目旨在加强各级的研究和教育。该仪器已在几个研究项目中使用。铁酶氧化血红素的机制正在研究中。过渡金属络合物的电子转移反应目前正在探索中。该光谱仪用于研究有机磁性半导体中钒的氧化催化剂和自旋交换机理。含硒化合物的氧化还原行为正在研究中。另一个研究领域是为主族元素发现新的成键催化作用。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award is jointly funded by the Chemical Instrumentation (CRIF) program, the Established Program to Stimulate Competitive Research (EPSCoR), and the Major Research Instrumentation (MRI) program. Professor Rory Waterman from the University of Vermont & State Agricultural College (UVT) and colleague Matthew Liptak are acquiring an X-band electron paramagnetic resonance (EPR) spectrometer. This spectrometer is used in various fields including chemistry, biology, and physics. The spectrometer allows observation of transitions when electrons in a magnet field are irradiated with microwaves. The spectrum obtained gives valuable information about the composition of a sample. This information provides insight on the environment near the atom and the properties of the system. For example, the instrument is used to rapidly screen candidate materials for photovoltaic devices to optimize solar cell efficiency. The instrument is housed and managed at the University of Vermont. It provides service to researchers across Vermont as well as a broad swath of New England and upstate New York. The instrument is used to train undergraduate and graduate students in research and in lecture and laboratory courses preparing them for the modern workforce. It also impacts high school students since UVT has programs in place to foster this early STEM education interaction. The project is aimed at enhancing research and education at all levels. The instrument is used in several research projects. The mechanism of heme oxygenation by iron enzymes is under investigation. Electron-transfer reaction of transition metal complexes are currently being explored. The spectrometer is used to study vanadium oxidation catalysts and the mechanism of spin exchange in organic magnetic semiconductors. The redox behavior of selenium containing compounds is under investigation. Another research area is the discovering of new bond-forming catalysis for the main-group elements.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
