This award is jointly funded by the Major Research Instrumentation Program, the Chemistry Research Instrumentation Program, and the Established Program to Stimulate Competitive Research (EPSCoR). The University of Nevada, Reno is purchasing a single crystal diffractometer equipped with copper and molybdenum sources to support the research of Professor Ana de Bettencourt-Dias with colleagues Yftah Tal-Gan and Christopher Jeffrey. This instrument facilitates research in luminescent materials and f element chemistry, bacterial communication and quorum sensing, chemical ecology, and natural products chemistry. In general, an X-ray diffractometer allows accurate and precise measurements of the full three-dimensional structure of a molecule, including bond distances and angles, and provides accurate information about the spatial arrangement of a molecule relative to neighboring molecules. The features of this instrument enhance the research efforts of faculty and students; it is also successfully deployed as part of the teaching efforts of students at all levels in many departments at the University of Nevada, Reno and in teaching and outreach in the Northern Nevada region. Most notably, students from area high schools learn about the technique, and the history of its development, and have access to determine the structure of simple compounds isolated as part of their science curriculum. The award is aimed at enhancing research and education at all levels. The research enabled by the acquisition of this instrument spans a wide range of areas in chemistry, biochemistry, biology and materials science, namely, luminescent materials, f element chemistry, bacterial communication and quorum sensing, chemical ecology, organometallic chemistry and catalysis, medicinal chemistry, molecular materials for electronics applications, polyaromatic hydrocarbons, sensors, theranostics, f element separation, metallacycles, biological activity of polyacetylenes, biopolymers, plant cell wall biology and muscle proteins. The availability of the instrument with dual copper and molybdenum sources allows the research groups to gain insights from the structural characterization of small molecules, macromolecules and metalorganic frameworks, and the determination of absolute structure of light-atom molecules. These further our knowledge in the areas mentioned above, and the structural information collected cannot be accessed by any other technique. The research of a total of 16 investigators and their research groups spanning 5 institutions, which include 2 NSF CAREER recipients, 4 junior, 5 female and 4 Hispanic investigators, is impacted by the availability of the instrument. Students from varied socio-economic backgrounds have access to a technique that is not usually part of the undergraduate curriculum, which provides them with an important marketable skill. In addition, a collaboration with a local school provides high school seniors with a more in-depth understanding of the importance of structural characterization in the sciences.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计划，化学研究仪器计划和刺激竞争性研究的既定计划（EPSCoR）共同资助。位于里诺的内华达州大学正在购买一台配备铜和钼源的单晶衍射仪，以支持Ana de Bettencourt-Dias教授与同事Yftah Tal-Gan和Christopher Jeffrey的研究。该仪器促进了发光材料和f元素化学，细菌通讯和群体感应，化学生态学和天然产物化学的研究。一般来说，X射线衍射仪允许准确和精确地测量分子的完整三维结构，包括键距和角度，并提供关于分子相对于相邻分子的空间排列的准确信息。该仪器的功能增强了教师和学生的研究工作;它也被成功地部署为内华达州里诺大学许多部门各级学生的教学工作的一部分，并在北方内华达州地区的教学和推广。最值得注意的是，来自地区高中的学生学习该技术及其发展历史，并有机会确定作为其科学课程一部分的简单化合物的结构。该奖项旨在加强各级的研究和教育。通过收购该仪器实现的研究涵盖了化学，生物化学，生物学和材料科学的广泛领域，即发光材料，f元素化学，细菌通讯和群体感应，化学生态学，有机金属化学和催化，药物化学，电子应用分子材料，多环芳烃，传感器，治疗诊断学，f元素分离，金属环，聚乙炔、生物聚合物、植物细胞壁生物学和肌肉蛋白的生物活性。具有铜和钼双源的仪器的可用性使研究小组能够从小分子，大分子和金属有机框架的结构表征以及轻原子分子绝对结构的测定中获得见解。这些进一步我们在上述领域的知识，收集的结构信息不能通过任何其他技术访问。 共有16名研究人员及其研究小组跨越5个机构，其中包括2名NSF CAREER收件人，4名初级，5名女性和4名西班牙裔研究人员的研究受到该工具可用性的影响。来自不同社会经济背景的学生有机会获得通常不是本科课程的一部分的技术，这为他们提供了重要的市场技能。此外，与当地一所学校的合作使高中毕业生更深入地了解了结构表征在科学中的重要性。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
