Acquisition of a Comprehensive High Temperature and High Purity Glove Box Materials Processing Facility for Education and Research

这笔赠款支持爱荷华州立大学为教育和研究购置综合高温和高纯度手套箱材料加工设施。新材料开发过程中最重要的变化之一是材料加工的尖端程度。现代材料现在是在原子水平上设计的，对成分、结构和杂质的精确控制使新材料能够制造出具有特殊性能和性能的新材料。目前的几个项目严重依赖于高质量的手套箱系统提供的清洁、干燥和无氧的环境。这一新的最先进的手套箱制备系统将极大地提高材料的质量、纯度和结构。这个项目具有重大的智力价值，因为新的手套箱系统将被中西部地区的大约8个不同的研究小组用于各种项目。这一多功能手套箱将使人们能够制备具有优异导电性的新的快速离子导电玻璃，新的光子带隙材料将被处理成前所未有的可能结构，新的透明导电氧化物将被制备得异常纯净，新的铁电材料将被处理得异常纯净，以便能够研究微小故障的细节，新的超磷酸盐玻璃将被制备成能够对离子导电性的频率依赖性有新的见解，最后将以前所未有的功能水平处理新型聚合材料。由于本科生和研究生使用手套箱处理系统的水平较高，本项目具有重大而广泛的影响。ISU几乎所有材料科学与工程(MSE)的学生都将使用手套箱系统，它将形成一个核心研究设施。附近本科院校的本科生研究小组、科学院和克雷顿大学，以及印第安纳大学和密苏里大学罗拉分校的研究小组作为中西部地区机构，将受益于其他方面

This grant provides support for the acquisition of a comprehensive high temperature and high purity glove box materials processing facility for education and research at Iowa State University. One of the most significant changes in the development of new materials is the sophistication in the processing of the materials. Modern materials are now being designed at the atomic level and precise control of the composition, structure, and impurities are allowing new materials to be fabricated with exceptional properties and performance. Several current projects critically depend upon the clean, dry, and oxygen-free environment afforded by a high quality glove box system. This new state-of-the-art glove box preparation system will dramatically improve the quality, purity, and structure of the materials. This project has significant intellectual merit in that the new glove box system will be used by ~ 8 different research groups across the Midwest on a wide variety of projects. This multi-purpose glove box will enable new fast ion conducting glasses to be prepared that have exceptional conductivities, new photonic band gap materials will be processed with never before possible structures, new transparent conducting oxides will be prepared with exceptionally purity, new ferroelectric materials will be processed at exceptional purity so that the details of the micro-failure can be examined, new ultraphosphate glasses will be prepared that will enable new insights into the frequency dependence of the ionic conductivity, and finally a new class of polymeric materials will be processed with unprecedented levels of functionality. This project has significant broader impact due to the high level of undergraduate and graduate student use of the glove box processing system. Nearly all students in Materials Science and Engineering (MSE) at ISU will use the glove box system and it will form a core research facility. Undergraduate research groups at nearby undergraduate institutions, Coe College and Creighton University, and as a Midwest Regional Facility by research groups at the University of Indiana and the University of Missouri-Rolla, will benefit, among others
