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

0618924 HoThis MRI（Major Research Instrumentation）proposal is for Lamar University to acquire aSEM/EDX（Scanning Electron Microscopy - Energy Dispersive X-ray Spectroscopy）system for education and research projects carried out in the University，especially in Colleges ofEngineering and Arts Sciences.拉马尔大学是一个非博士学位。它是一个资助机构，正在迅速发展环境以及能源/材料相关研究的专门知识。这一发展的目标是建立其研究基础设施和能力，这两者都是在目标研究领域，特别是空气质量研究中有效开展高级研究项目所急需的。拉马尔大学被各种化学工业所包围，这些工业具有巨大的排放空气污染物的潜力。该大学迫切需要发展测量空气污染物的能力。所获得的SEM/EDX将主要用于该地区采集的样品的颗粒物（PM）表征，为采用EPA开发的CMAQ（Community Multi-scale Air Quality）、CMB（Chemical Material Balance）、PMF（Positive Matrix Factorization）和PMX（因其功能是分解化学物质浓度而得名）模型进行该地区PM的源解析提供必要的数据。

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.
