0922851Van AkenMissouri S&TTechnical AbstractAcquisition of an analytical transmission electron microscope (TEM) will complement and expand the Advanced Materials Characterization Lab (AMCL) at Missouri S&T. The proposed TEM will be equipped with a Schottky field emission gun and an X-ray energy dispersive spectrometer (XEDS), capable of operating in both conventional TEM mode and scanning transmission (STEM) mode. The enhanced capabilities of the TEM in the area of high resolution imaging, atomic number sensitive (Z-contrast) imaging, nano-beam electron diffraction, and XEDS line-scan/mapping will provide state-of-the-art materials characterization at Missouri S&T. Nearly a quarter of the 270 tenure track faculty members at Missouri S&T are engaged in materials-related research, cutting across 13 of the 21 academic departments on campus. Other institutions that will benefit from the acquisition of this equipment include the Research Alliance of Missouri and the Missouri Nanoalliance, organizations dedicated to facilitating collaborative nanoscience research in the State of Missouri. The TEM will be utilized in a number of projects, including: 1) structure/ chemistry/ property relations of 3rd generation advanced high strength steels, 2) domain structures and interface studies of epitaxial metal oxides films and superlattices, 3) structural and compositional inhomogeneities in friction stir processed aluminum alloys, 4) interface structure and concentration gradients in catalyst-dispersed nanowire arrays for proton exchange membrane fuel cells, 5) impurity segregation and defect interactions at grain boundaries in ultra-high temperature ceramics, 6) structure, defects and doping properties at grain boundaries of high temperature superconducting materials, and 7) glass/ceramic interfacial chemistry for the application in solid oxide fuel cells. The proposed instrument will be managed by the AMCL at Missouri S&T. Non-technicalAnalytical transmission electron microscopes are an essential tool in the development of new materials with nano-scale structures. This new instrument will be used to develop lightweight steel, new materials to generate electricity, new superconducting magnets, and high temperature heat shields. Other institutions that will benefit from the acquisition of this equipment include the Research Alliance of Missouri and the Missouri Nanoalliance, organizations dedicated to facilitating collaborative nanoscience research and facility development in the State of Missouri. The proposed instrument will be managed by the Advanced Materials Characterization Laboratory (AMCL) at the Missouri University of Science and Technology (Missouri S&T). The proposed equipment will be immediately utilized in several undergraduate and graduate level classes in the areas of materials characterization and evaluation, where 200 Materials Science and Engineering students are exposed to cutting edge research in NSF-funded projects. In addition, the instrument will enhance recruitment efforts at the undergraduate and graduate levels at Missouri S&T, through programs such as the Opportunities for Undergraduate Research Experience (OURE), and the many summer programs coordinated by the Office of Pre-College Programs such as the Jackling Introduction to Engineering and the Materials Camp. Last year over 1,300 K-12 students were on campus, and most toured through the AMCL.

密苏里州技术摘要获得分析透射电子显微镜（TEM）将补充和扩大密苏里州S T的先进材料表征实验室（AMCL）。拟议的TEM将配备肖特基场发射枪和X射线能量色散谱仪（XEDS），能够在传统的TEM模式和扫描透射（STEM）模式下工作。 TEM在高分辨率成像、原子序数敏感（Z衬度）成像、纳米束电子衍射和XEDS线扫描/绘图领域的增强能力将在密苏里州ST提供最先进的材料表征。在密苏里州ST的270名终身教职员工中，近四分之一从事与材料相关的研究，横跨校园21个学术部门中的13个。 其他将从购买这一设备中受益的机构包括密苏里州研究联盟和密苏里州纳米联盟，这些组织致力于促进密苏里州的纳米科学合作研究。TEM将用于一些项目，包括：1）第三代先进高强度钢的结构/化学/性能关系，2）外延金属氧化物膜和超晶格的畴结构和界面研究，3）摩擦搅拌处理的铝合金中的结构和成分不均匀性，4）用于质子交换膜燃料电池的催化剂分散纳米线阵列中的界面结构和浓度梯度，5）超高温陶瓷中晶界处的杂质偏析和缺陷相互作用，6）高温超导材料的晶界结构、缺陷和掺杂性质; 7）固体氧化物燃料电池中应用的玻璃/陶瓷界面化学。拟议的仪器将由密苏里州ST的AMCL管理。非技术分析透射电子显微镜是开发具有纳米级结构的新材料的重要工具。这种新仪器将用于开发轻质钢、发电新材料、新型超导磁体和高温隔热板。其他机构将受益于购买这种设备包括研究联盟的密苏里州和密苏里州纳米联盟，组织致力于促进合作纳米科学研究和设施的发展在密苏里州。该仪器将由密苏里州科技大学（密苏里州ST）的先进材料表征实验室（AMCL）管理。拟议的设备将立即用于材料表征和评估领域的多个本科生和研究生级别课程，其中200名材料科学与工程学生将接触NSF资助项目的尖端研究。此外，该仪器将加强招聘工作在本科和研究生水平在密苏里州ST，通过计划，如本科生研究经验的机会（OURE），以及许多暑期课程由大学预科课程办公室协调，如杰克林介绍工程和材料营。 去年，超过1,300名K-12学生在校园里，大多数人通过AMCL参观。
