MRI: Acquisition of a Scanning Electron Microscopy/Energy Dispersive X-ray Spectroscopy System for Multi-Disciplinary Research and Education

[06:18924]这项MRI（主要研究仪器）提案是为拉马尔大学获得aSEM/EDX（扫描电子显微镜-能量色散x射线光谱学）系统，用于在大学进行的教育和研究项目，特别是在工程学院和艺术与科学学院。拉马尔大学是一个非博士。在环境和能源/材料相关研究方面，授予机构和正在迅速发展的专业知识。这一发展的目标是建立其研究基础设施和能力，这两者对于有效开展目标研究领域的先进研究项目，特别是空气质量研究，都是至关重要的。拉马尔大学周围环绕着各种化学工业，这些工业排放空气污染物的潜力巨大。该大学迫切需要发展测量空气污染物的能力。获得的SEM/EDX将主要用于该地区收集的样品的颗粒物（PM）表征，为采用epa开发的CMAQ（社区多尺度空气质量），CMB（化学物质平衡），PMF（正矩阵分解）和UNMIX（因其功能而命名，即分解化学物质浓度）模型进行该地区PM的来源分配分析提供必要的数据。

0618924HoThis MRI (Major Research Instrumentation) proposal is for Lamar University to acquire aSEM/EDX (Scanning Electron Microscopy - Energy Dispersive X-ray Spectroscopy) system foreducation and research projects carried out at the University, especially in the Colleges ofEngineering and Arts & Sciences. Lamar University is a non-Ph.D. granting institution and israpidly developing expertise in environmental as well as energy/material related research. Thegoal of this development is to establish its research infrastructure and capabilities, both of whichare critically needed for effectively carrying out advanced research projects in target researchareas, particularly air quality research. Lamar University is surrounded by various chemicalindustries having huge potential to emit air pollutants. An urgent need for the University is todevelop capabilities to measure air pollutants. The acquired SEM/EDX will be mainly used forparticulate matter (PM) characterization of samples collected in this area, which providenecessary data for source apportionment analysis of PM for this area employing the EPAdeveloped CMAQ (Community Multi-scale Air Quality), CMB (Chemical Material Balance),PMF (Positive Matrix Factorization) and UNMIX (named for its function, which is to unmixthe concentrations of chemical species) models.
