MRI: Acquisition of an Electron Microprobe (EMP) for analysis of inorganic elemental concentrations in solid-state materials: Expanding science research and teaching in Iowa.

1126728Ukstins-Pate这项重大研究仪器拨款支持购买配备了五个波长色散光谱仪(WDS)、一个能量色散光谱仪(EDS)和阴极发光光谱仪的最先进的电子微探针(EMP)。EMP将支持校园内多个系的一系列研究和研究培训，广泛的主题包括：1)地球过程；2)可持续性与气候变化；3)污染预防与修复；4)行星地质学与陨石影响；5)地质考古学；以及6)公共卫生，所有这些都需要对固体材料进行微空间分辨的定量化学分析。例如，研究应用包括对弧形火山岩中记录的岩浆形成条件的创新性和有前途的研究，以及以利用电磁脉冲地质温压计技术对变质岩套的研究为依托的构造调查，以及对闪岩撞击过程的研究，对残留湖泊沉积物的古气候调查，以及对纳米颗粒聚集体和微生物在重金属化学循环中的作用的研究。PIS计划通过现有的研究生教育和教授联盟(AGEP)和爱荷华州工程院校范围内的种族包容计划，让未被充分代表的学生参与使用EMP的研究体验。***

1126728Ukstins-PeateThis Major Research Instrumentation grant supports acquisition of a state-of-the-art electron microprobe (EMP) equipped with five wavelength dispersive spectrometers (WDS), an energy dispersive spectrometer (EDS), and cathodoluminescence spectrometer. The EMP will support a range of research and research training across multiple departments on campus with broad themes including: 1) Earth Processes; 2) Sustainability & Climate Change; 3) Pollution Prevention & Remediation; 4) Planetary Geology & Meteorite Impacts; 5) Geoarchaeology; and 6) Public Health, all with needs for microspatially resolved quantitative chemical analysis of solid materials. Example research applications include innovative and promising studies of the conditions of magmagenesis as recorded in arc volcanics and tectonic investigations relying on study of metamorphic rock suites through use of EMP geothermbarometric techniques as well as studies of bolide impact processes, paleoclimate investigations of relict lake deposits, and studies of nanoparticle aggregates and the role of microbes in the chemical cycling of heavy metals. The PIs plan to engage underrepresented students in research experiences using the EMP through an extant Alliance for Graduate Education and Professoriate (AGEP) and the Ethnic Inclusion Program in Iowa Engineering institutional wide programs. ***
