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.

0618924HOTHIS MRI（主要的研究仪器）提案是供拉马尔大学获取ASEM/EDX（扫描电子显微镜 - 能量分散X射线光谱）系统的使用和在大学进行的研究项目，尤其是在工程学和艺术和艺术和艺术和艺术和艺术和艺术学院。拉马尔大学是一所无理。授予机构和伊斯兰教在环境以及能源/材料相关研究方面的专业知识。这一发展的目标是建立其研究基础设施和能力，这两者都是有效地在Target ResearchAreas（尤其是空气质量研究）中进行先进的研究项目所需的。拉马尔大学被各种化学工业所包围，具有发射空气污染物的巨大潜力。对大学的迫切需求是测量空气污染物的造型能力。所获得的SEM/EDX将主要用于该区域中收集的样品的参与物质（PM），该图表用于该领域的PM来源分配分析，该区域采用了Epadevended CMAQ（社区多尺度空气质量），CMB（化学材料平衡），PMF（PMF）（阳性Matrix rixpization）和INMIX（均具有化学浓度）的功能，该功能是功能，该功能为foldictations，是该功能，是该功能，该功能为fightimation，是该功能，是该功能的浓度。
