This project is jointly funded by the Division of Earth Sciences Instrumentation and Facilities and the Established Program to Stimulate Competitive Research (EPSCoR). The award will support acquisition of a scanning electron microscope (SEM) and ancillary field equipment including a water quality sonde, data logger, and a weather station, to support research and research training at Wichita State University. The equipment will benefit multiple WSU researchers for studies in geology, biology, chemistry, anthropology, and engineering with relevance to societal interests including reducing and remediating toxic elements introduced into the subsurface, studies of hydrophobic composite materials to harvest water vapor in arid regions, and studies of mineral-microbe interactions in hypersaline environments. The instrumentation will support graduate and undergraduate student experiential learning and research training and the investigators intend to conduct instrument-mediated outreach to local K-12 students and educators.The equipment will be used foremost for investigations of the transport and fate of natural and man-made colloidal materials in groundwaters and soils, with field equipment deployed at a local University managed nature preserve (the Ninnescah Reserve). The SEM will facilitate micron to sub-micron scale imaging of the interactions between natural and synthetic colloids with mineral surfaces with implications for understanding the subsurface transport and fate of metal contaminants adsorbed to natural organic materials and studies of potential remediation techniques for neutralizing acid mine drainage.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目由Earth Sciences仪器和设施的部门以及刺激竞争研究的既定计划（EPSCOR）共同资助。 该奖项将支持扫描电子显微镜（SEM）和辅助现场设备的获取，包括水质SONDE，数据记录仪和气象站，以支持威奇托州立大学的研究和研究培训。 该设备将使多个WSU研究人员在地质，生物学，化学，人类学和工程学领域的研究中受益，并与社会利益相关，包括减少和补救的有毒元素引入了地下，研究疏水性复合材料的研究以在干旱地区收集水蒸气，以及矿物质菌相互作用的研究。 该仪器将支持毕业生和本科生的体验学习和研究培训，并且研究人员打算向当地的K-12学生和教育工作者进行仪器介导的范围。该设备将用于调查自然和人造胶体材料的运输和命运，并在地狱和土壤中，由当地的现场设备在当地的大学管理自然保护区（NINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINNINENSC）进行调查。 SEM将促进Micron与矿物表面的自然和合成胶体之间的相互作用的亚微米尺度成像，这对了解具有自然有机材料的地下运输和命运的意义，以及对天然有机材料的命运以及对潜在补救技术的研究，对中和酸矿物的缺陷进行了支持。更广泛的影响审查标准。
