项目摘要
This award is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. The University of California Los Angeles is acquiring a continuous wave electron paramagnetic resonance (CW-EPR) spectrometer to support research of Professor Paula Diaconescu and colleagues Greg Carman, Miguel Garcia-Garibay, Sarah Tolbert and Chong Liu. This instrument allows research in a variety of fields such as those that provide insight on how biologically relevant species with unpaired electrons behave. In general, an EPR spectrometer yields detailed information on the geometric and electronic structure of molecular and solid-state materials. It is also used to obtain information about the lifetimes of free radicals, short-lived, highly reactive species involved in valuable chemical transformations as well as the initiation of possible pathological growth. This instrument is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution as well as collaborators from regional institutions such as those in the Cal State System as well as nearby minority serving institutions.The award of the EPR spectrometer is aimed at enhancing research and education at all levels. It especially impacts the characterization of pre-catalysts with unpaired electrons, mixed valence metal complexes, and paramagnetic lanthanide complexes used to prepare optically active molecular spin qubits and the study of rotational dynamics of different magnetic organic frameworks with stable nitroxyl radicals. The instrumentation is also used to search for materials for multiferroic antennas and for the rapid screening of magnetic loss in new dynamic magnetoelastic materials. In addition, it allows the characterization of doped semiconducting polymers and studies of boron-based stable radical species. The instrument also serves researchers designing rules and understanding the effect of 3-dimensional aromatic radicals on how their electronic properties can be rationally tuned and deliberately manipulated and to understand catalytic methane air oxidation to methanol by reactive oxygen.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.
该奖项由主要研究仪器和化学研究仪器计划支持。加州洛杉矶大学正在购买一台连续波电子顺磁共振(CW-EPR)光谱仪,以支持Paula Diaconescu教授及其同事Greg卡曼、Miguel Garcia-Garibay、Sarah Tolbert和Chong Liu的研究。该仪器允许在各种领域进行研究,例如那些提供关于具有未配对电子的生物相关物种如何表现的洞察力的领域。一般来说,EPR光谱仪可以提供有关分子和固态材料的几何和电子结构的详细信息。它还用于获得有关自由基寿命的信息,这些自由基是参与有价值的化学转化以及可能的病理性生长起始的短寿命、高反应性物种。该仪器是教学的一个组成部分,以及研究和研究培训的本科生和研究生在化学和生物化学在这个机构,以及合作者从区域机构,如那些在加州州立大学系统以及附近的少数民族服务机构。EPR光谱仪的奖项旨在加强各级的研究和教育。它特别影响了用于制备光学活性分子自旋量子比特的具有未成对电子的前催化剂,混合价金属络合物和顺磁镧系络合物的表征,以及具有稳定硝酰基自由基的不同磁性有机框架的旋转动力学研究。该仪器还用于寻找多铁性天线材料和快速筛选新的动态磁弹性材料中的磁损耗。此外,它允许掺杂的半导体聚合物的表征和基于硼的稳定自由基物种的研究。该仪器还有助于研究人员设计规则,了解三维芳香族自由基对电子性质的影响,并了解活性氧催化甲烷空气氧化为甲醇。该奖项反映了NSF的法定使命,并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。
