This award is supported by the Major Research Instrumentation program. The City University of New York College of Staten Island (CSI) is acquiring a Mössbauer spectrometer to support the research of Professor Rupal Gupta at CSI and colleagues Rachel Austin and Michael Campbell from Barnard College and David Lacy from the State University of New York University at Buffalo. This spectrometer, which relies on interactions of gamma rays with the chemical element iron, allows research in a variety of fields such as functional and structural studies of non-heme iron dioxygenases responsible for carbon cycling, determining active site structure function relationships in alkane monooxygenase (AlkB), investigating electronic switching in iron metal–organic frameworks with redox-active ligands, understanding the evolutionary optimization of diiron enzymes, studying the behavior of iron in potentially multiferroic perovskite oxides, and carrying out mechanistic studies of the type II iron dioxygenases. In general, Mössbauer spectroscopy is a powerful tool to probe the chemical environments and reactivities of molecules, where probing the environments of iron atoms provides information about the chemistry of the rest of the molecule. Access to this type of equipment is important to chemists carrying out cutting edge research in fields as diverse as biochemistry and materials science. This instrument is the only one of its type in the New York City region, and it is an integral part of teaching as well as research at undergraduate, master’s and Ph.D. levels, with faculty from nearby institutions joining CSI in utilizing it for both research and teaching.The award of the Mössbauer spectrometer is aimed at enhancing research and education at all levels. It especially impacts the diverse student bodies at both CSI, a Hispanic-serving institution, and Barnard College, a women’s college, and the instrument is incorporated into course work at both colleges, as well as being incorporated into a workshop for high school students. The instrument particularly provides a complete and detailed description of the amount, oxidation state and the electronic and nuclear properties of Fe centers in chemical samples of interest, with the ubiquity of iron in chemistry making this technique appropriate for instrumentation that is shared by multiple researchers.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.

该奖项得到了主要的研究工具计划的支持。纽约市史坦顿岛大学（CSI）正在收购Mössbauer光谱仪，以支持CSI的Rupal Gupta教授和Barnard College的Rachel Austin和Michael Campbell和纽约州州立大学Buffalo大学的Barnard College的Rachel Austin和Michael Campbell的研究。 This spectrometer, which relies on interactions of gamma rays with the chemical element iron, allows research in a variety of fields such as functional and structural studies of non-heme iron dioxygenases responsible for carbon cycling, determining active site structure function relationships in alkane monooxygenase (AlkB), investigating electronic switching in iron metal–organic frameworks with redox-active ligands, understanding the evolutionary optimization of diron酶，研​​究铁在潜在的多铁钙岩氧化物中的行为，并对II型铁二氧酶进行机械研究。通常，Mössbauer光谱是探测分子化学环境和反应性的强大工具，其中探测铁原子的环境提供了有关分子其他分子化学性质的信息。使用此类设备对于在像生物化学和材料科学这样的潜水场所进行尖端研究的化学家很重要。乐器是纽约市地区唯一的类型，它是本科，硕士和博士学位的教学和研究的组成部分。层次，随着近乎机构的教职员工加入CSI，将其用于研究和教学。莫斯鲍尔光谱仪的奖励旨在增强各级研究和教育。这尤其影响了西班牙裔服务机构CSI的潜水员学生团体和一所女子学院的Barnard College，并且该乐器都在两所学院的课程中纳入了课程，并被纳入了高中生的工作室中。该仪器特别提供了FE中心在感兴趣的化学样本中的数量，氧化状态以及电子和核性质的完整详细描述，化学中铁的无处不在，使该技术适用于多个研究人员共享的仪器。该奖项反映了NSF的法定任务，并通过评估智力的MERIT和BRODIT和BRODIT和BRODIT和BRODIT和BRODIT和BRODIT和广泛的影响。
