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.

该奖项由主要的研究工具和化学研究工具计划共同支持。加利福尼亚州立大学东湾（East Bay）正在购买带有能量X射线光谱仪（SEM-EDS）仪器的台式扫描电子显微镜，以支持Stephanie Zaleski教授和同事Marlin Halim，Ruth Tinnacher和James Murray的研究。通常，SEM-EDS可实现敏感的微观至纳米级结构成像，并结合元素映射，研究从半导体设备到微生物的材料。该奖项推进了纳米科学，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潜水领域的研究。该奖项针对的是，在化学和生物化学，生物学，人类学，地理学和环境研究，刑事司法，工程和物理学的化学和生物化学，生物科学，人类学，地理学和物理学，生物学，人类学，地理学和物理学，生物科学，人类学，地理学和物理学，对高度多样化的本科和硕士学位学生人数的教育，研究和研究培训。该乐器还与国家实验室，大学，社区学院，高中和艺术博物馆的外部合作者进行研究和外展工作。该奖项旨在增强各级研究和教育。具体而言，该仪器使研究重点表征自组装金纳米颗粒膜的结构 - 特性关系，用于分子传感器应用，并研究油漆膜中的降解现象。其他研究项目包括检测海sl中的Fe相关结构，并了解它们在地磁灵敏度中的作用以及在金属纳米颗粒上使用GD-Aptamer负载密度的表征，以用作对比剂和传感器。仪器还用于调查铀在粘土和其他矿物表面上增加的性质，以便在未来的核废料存储库中使用，并使用其他环境地球化学问题。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来通过评估来支持的。
