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

1126728 Ukstins-Peate这一重大研究仪器补助金支持购买最先进的电子探针（EMP），配备五个波长色散光谱仪（WDS），能量色散光谱仪（EDS）和阴极发光光谱仪。 EMP将支持校园内多个部门的一系列研究和研究培训，主题广泛，包括：1）地球过程; 2）可持续性气候变化; 3）污染预防补救; 4）行星地质陨石影响; 5）地质考古学;和6）公共卫生，所有这些都需要固体材料的微观空间解析定量化学分析。 示例研究应用包括创新和有前途的研究岩浆作用的条件下记录在弧火山和构造调查依靠研究变质岩套房通过使用电磁脉冲geothermarometric技术，以及研究火流星的影响过程，古气候调查残留湖泊沉积物，和纳米颗粒聚集体的研究和微生物在重金属的化学循环中的作用。 PI计划通过现存的研究生教育和教授联盟（AGEP）和爱荷华州工程学院范围内的种族包容计划，让代表性不足的学生参与EMP的研究经验。 ***

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. ***
