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.

该奖项由化学仪器（CRIF）计划，刺激竞争性研究的既定计划（EPSCoR）和主要研究仪器（MRI）计划共同资助。佛蒙特州立大学农学院（UVT）的Rory Waterman教授和同事Matthew Liptak正在购买一台X波段电子顺磁共振（EPR）光谱仪。该光谱仪用于包括化学、生物学和物理学在内的各个领域。光谱仪允许观察磁场中的电子被微波照射时的跃迁。所获得的光谱提供了关于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了解。例如，该仪器用于快速筛选光伏器件的候选材料，以优化太阳能电池效率。该仪器由佛蒙特大学保管和管理。它为佛蒙特州以及新英格兰和纽约北部的广大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和讲座和实验室课程，为他们的现代劳动力做好准备。它也影响高中学生，因为UVT有计划，以促进这种早期的STEM教育互动。该项目旨在加强各级的研究和教育。该仪器已用于多个研究项目。铁酶氧化血红素的机制正在研究中。 过渡金属配合物的电子转移反应目前正在探索中。该光谱仪用于研究钒氧化催化剂和有机磁性半导体中的自旋交换机理。含硒化合物的氧化还原行为正在研究中。该奖项反映了NSF的法定使命，通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
