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.
