MRI: Acquisition of a Field Emission-Scanning Electron Microscope for Nanoscience Research and Education

德克萨斯农工大学金斯维尔分校（TAMUK）是一所西班牙裔服务机构，正在寻求资金购买一台场发射扫描电子显微镜（FE-SEM）仪器，以使环境工程和物理科学中的纳米科学研究成为可能，并加强当前的分析基础设施。该仪器将使南德克萨斯州的研究人员能够开展重要的地方、区域和国家需要的研究和教育活动。多学科研究领域立即受益于使用拟议的FESEMinstrument在环境工程，化学工程，化学和生物学系TAMUK。FE-SEM将用于与美国国家科学基金会的使命和重点相关的研究活动，包括：1)有害空气污染物在工程纳米材料上的吸附；2)环境中人造纳米颗粒的鉴定和暴露评价；3)应用于绿色能源的溶胶-凝胶衍生催化剂的表征；4)新型闪蒸纺丝工艺中微纳纤维的结构表征；5)钙质有孔虫氨帕金森虫中二氧化硅沉积；6)颗粒聚集/分解和降水对河流水系细悬浮沉积物和污染物运移的影响；7)用于场效应晶体管的高性能有机半导体；8)反渗透膜损伤和污染的表征。

CBET-0821370RamirezTexas A&M University-Kingsville (TAMUK), a Hispanic Serving Institution, seeks funding toacquire a Field Emission-Scanning Electron Microscope (FE-SEM) instrument to enableresearch in nanoscience in environmental engineering and physical science and to enhancecurrent analytical infrastructure. This instrument will allow researchers in South Texas toconduct research and educational activities of important local, regional and national needs.Multidisciplinary research areas immediately benefiting from the use of the proposed FESEMinstrument are in the Departments of Environmental Engineering, Chemical Engineering,Chemistry and Biology at TAMUK. The FE-SEM will be used in research activities related to theNational Science Foundation's mission and focus including 1) adsorption of hazardous airpollutants onto engineered nanomaterials; 2) identification and exposure assessment tomanufactured nanoparticles in the environment; 3) characterization of sol-gel derived catalystsapplied for green energy; 4) structural characterization of micro and nano fibers from novel flashspinning processes; 5) silica deposition in the calcareous foraminiferan ammonia parkinsoniana;6) effects of particle aggregation/disaggregation and precipitation on the transport of finesuspended sediments and contaminants in river systems; 7) high performance organicsemiconductors for field effect transistors; and 8) characterization of reverse osmosismembrane damage and fouling.
