MRI: Track 1 Acquisition of a Desktop SEM-EDS for Advanced Material and Biological Characterization

该奖项由主要研究仪器和化学研究仪器项目联合支持。加州州立大学东湾分校正在购买一台带有能量色散x射线光谱（SEM-EDS）仪器的台式扫描电子显微镜，以支持Stephanie Zaleski教授及其同事Marlin Halim， Ruth Tinnacher和James Murray的研究。一般来说，SEM-EDS使敏感的微到纳米级结构成像与元素映射相结合，以研究从半导体器件到微生物的材料。该奖项促进了纳米科学、艺术保护、分子生物传感、环境地球化学和放射化学以及感觉生物学等不同领域的研究。该奖项旨在为科罗拉多州立大学东湾分校化学与生物化学、生物科学、人类学、地理与环境研究、刑事司法、工程和物理等系高度多样化的本科生和硕士生提供教育、研究和研究培训。该仪器还丰富了与国家实验室、大学、社区学院、高中和艺术博物馆的外部合作者的研究和外联工作。该奖项旨在加强各级的研究和教育。具体来说，该仪器可以研究自组装金纳米颗粒膜的结构-性能关系，用于分子传感应用，并研究油画膜的降解现象。其他研究项目包括检测海蛞蝓中的铁相关结构，了解它们在地磁传感中的作用，以及表征用作造反差剂和传感器的金属纳米颗粒上的gd适体装载密度。该仪器还用于研究铀在粘土和其他矿物表面吸附的性质，以便将来用于核废料储存库，以及其他环境地球化学问题。该奖项反映了美国国家科学基金会的法定使命，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。

This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs. California State University East Bay is acquiring a desktop scanning electron microscope with energy-dispersive X-ray spectroscopy (SEM-EDS) instrument to support the research of Professor Stephanie Zaleski and colleagues Marlin Halim, Ruth Tinnacher, and James Murray. In general, SEM-EDS enables sensitive micro- to nanoscale structural imaging combined with elemental mapping to study materials ranging from semiconductor devices to microorganisms. This award facilitates research across diverse fields such as nanoscience, art conservation, molecular biosensing, environmental geochemistry and radiochemistry, and sensory biology. This award targets the enhancement of educational, research, and research training for the highly diverse undergraduate and master’s level student population at CSU East Bay within the Departments of Chemistry and Biochemistry, Biological Sciences, Anthropology, Geography & Environmental Studies, Criminal Justice, Engineering, and Physics. The instrument also enriches research and outreach work with external collaborators at national laboratories, universities, community colleges, high schools, and art museums.This award is aimed at enhancing research and education at all levels. Specifically, the instrument enables research focusing characterizing of structure-property relationships of self-assembled gold nanoparticle films for molecular sensing applications and investigating degradation phenomena in oil paint films. Additional research projects include detecting Fe-associated structures in sea slugs and understanding their role in geomagnetic sensing and the characterization of Gd-aptamer loading density on metallic nanoparticles for use as contrast agents and sensors. The instrumentation is also used to investigate the nature of uranium adsorption onto clay and other mineral surfaces for use in future nuclear waste repositories, and other environmental geochemistry questions.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.
