项目摘要

Research Catalyst projects provide support for Historically Black Colleges and Universities to work towards establishing research capacity of faculty to strengthen science, technology, engineering and mathematics undergraduate education and research. It is expected that the award will further the faculty member's research capability, improve research and teaching at the institution, and involve undergraduate students in research experiences. The project at Winston Salem State University will investigate novel approaches to ion mobility spectrometry (IMS) when coupled with a membrane sampler for the separation, detection and identification of different classes of compounds in complex matrices. This work will provide research opportunities for undergraduate chemistry majors, while preparing them for careers in STEM.The goal of this project is to utilize a novel sample introduction sampler system (SIS) as a single unit using polydimethylsilicone (PDMS) membranes and nanoparticle materials. This will allow sampling, isolation, pre-concentration, separation, and desorption of key environmental pollutants in a single step. The uniqueness of this study is the use of temperature programming similar to a gas chromatography oven, to analyze solid, liquid, and gas samples. Interfacing the unit to an ion mobility spectrometry (IMS) will allow the detection of volatile organic compounds (VOCs) and semi-volatile organic compounds (semi-VOCs) of extreme environmental concern. This project has the potential to develop a sampling and sample introduction approach that requires little or no preparation and use of less or no solvent, is not labor intensive, and has greater analytical reliability. The long-term goal is to use this method for collecting samples in indoor buildings and sites suspected to have been exposed to contaminants and for analyzing water contaminated with VOCs.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.

研究催化剂项目为历史上的黑人学院和大学提供支持，以建立教师的研究能力，加强科学、技术、工程和数学本科教育和研究。预计该奖项将进一步提高教师的研究能力，提高学院的研究和教学水平，并让本科生参与研究经验。温斯顿塞勒姆州立大学的项目将研究离子迁移率光谱法（IMS）的新方法，该方法与膜采样器相结合，用于分离、检测和鉴定复杂基质中不同类别的化合物。这项工作将为本科化学专业的学生提供研究机会，同时为他们在STEM领域的职业生涯做好准备。该项目的目标是利用聚二甲基硅酮（PDMS）膜和纳米颗粒材料，将一种新型的样品导入采样器系统（SIS）作为单个单元。这将允许采样，隔离，预浓缩，分离，并在一个步骤中解吸关键的环境污染物。这项研究的独特之处在于使用类似于气相色谱炉的温度编程来分析固体、液体和气体样品。将该装置连接到离子迁移率光谱（IMS）将允许检测极端环境关注的挥发性有机化合物（VOCs）和半挥发性有机化合物（semi-VOCs）。该项目有潜力开发一种取样和样品导入方法，该方法需要很少或不需要准备，使用较少或不使用溶剂，不需要劳动密集型，并且具有更高的分析可靠性。长期目标是使用这种方法在室内建筑物和疑似接触污染物的场所收集样本，并分析被挥发性有机化合物污染的水。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。
