LEAPS-MPS: Nano-Projectile Secondary Ion Mass Spectrometry for accurate molecular analysis at the nanoscale

该奖项全部或部分根据2021年美国救援计划法案（公法117-2）资助。在这个项目中，由数学和物理科学理事会资助，设在化学部，教授迈克尔埃勒和他的学生在加州州立大学北岭（CSUN）在北岭，加利福尼亚州将开发新的分析工具，用于检查纳米粒子和分子排列在尺度接近5纳米。以高空间分辨率检查这些材料将为纳米尺度上发生的基本和材料过程提供重要见解。教授埃勒将扩大在干研究代表性不足的少数民族的参与，通过两种专注于提供实践经验的方法。(1)发展一个新的质谱实验室课程及（2）为本地K-12学生提供外展机会。埃勒教授将发展基于二次离子质谱（西姆斯）的纳米分子分析新方法。该研究将研究使用大量金簇作为西姆斯射弹来检查纳米颗粒和分子组装体，目标是在接近5 nm的尺度上阐明分子组织。该项目的结果将为低维材料和纳米结构表面的纳米颗粒表面相互作用提供新的见解。埃勒教授将开发一个相互关联的研究和教育计划，这将与CSUN的机构目标，鼓励学生从代表性不足的群体，积极参与和成功的STEM研究领域。这个奖项反映了NSF的法定使命，并已被认为是值得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的支持。

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.
