This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). In this project, funded by the Mathematical and Physical Sciences Directorate and housed in the Chemistry Division, Professor Michael Eller and his students at California State University Northridge (CSUN) in Northridge, CA will develop new analytical tools for examining nanoparticles and molecular arrangements at scales approaching 5 nanometers. Examining these materials with high spatial resolution will provide critical insights into fundamental and materials processes occurring at the nanoscale. Professor Eller will broaden participation of underrepresented minorities in STEM research through two approaches focused on providing hands-on experiences. (1) Developing a new mass spectrometry laboratory course and (2) providing outreach opportunities to local K-12 students.Professor Eller will develop new analytical methods for nanoscale molecular analysis based on secondary ion mass spectrometry (SIMS). The research will investigate the use of massive gold clusters as SIMS projectiles to examine nanoparticles and molecular assemblies, with the goal of elucidating molecular organization at a scale approaching 5 nm. The results of the project will provide new insights into nanoparticle-surface interactions with low-dimensional materials and nanostructured surfaces. Professor Eller will develop an interconnected research and educational program which will work in concert with CSUN’s institutional goal of encouraging students from underrepresented groups to actively participate and succeed in STEM research fields.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.

该奖项是根据2021年《美国救援计划法》（公法117-2）全部或部分资助的。在该项目中，由数学和物理科学局资助并位于化学部门，迈克尔·埃勒（Michael Eller）教授及其学生在加利福尼亚州诺斯里奇（Northridge）的加利福尼亚州立大学诺斯里奇（CSUN），将开发新的分析工具，用于检查纳米颗粒和分子布置，以尺度接近5纳米纳米。使用高空间分辨率检查这些材料将为纳米级发生的基本和材料过程提供重要的见解。埃勒教授将通过两种致力于提供动手经验的方法来扩大代表性不足的少数群体参与STEM研究。 （1）开发新的质谱实验室课程和（2）为本地K-12学生提供外展机会。专家Eller将开发基于次级离子质谱法（SIMS）的纳米级分子分析的新分析方法。该研究将研究大量金簇作为SIMS预测检查纳米颗粒和分子组件的使用，其目的是以5 nm的规模阐明分子组织。该项目的结果将为纳米颗粒表面相互作用提供新的见解与低维材料和纳米结构的表面。 Eller教授将开发一项相互联系的研究和教育计划，该计划将与CSUN的机构目标共同开发，即鼓励来自代表性不足的团体的学生积极参与并成功参与STEM研究领域。这项奖项反映了NSF的法定任务，并通过使用该基金会的知识分子的智力和广泛的影响来评估NSF的法定任务。
