1337731YangTechnical AbstractThis Major Research Instrumentation Award supports the acquisition of an environmental transmission electron microscope (ETEM), a high-resolution electron microscope with a simplified differential pumping system that permits gas introduction directly into the column. As a conventional TEM the instrument will enhance the current electron microscopy capabilities in teaching, user training and research. The capability to visualize structural changes at the sub-nanoscale level under operational environmental conditions will bring essential insights to many materials issues, such as the effect of dopants and impurities on processing and corrosion, defect (dislocation, grain boundaries and interface) migrations, thermally induced phase transformations, heterogeneous catalyses, nano-scale functional materials, and the environmental stability of materials in general. The low accelerating voltage minimizes damage of oxide species and soft materials, thereby providing the ability to visualize the dynamics of polymers, tissue engineering, drug delivery, biomaterials and biomineralization. This will be the first ETEM in the greater Western Pennsylvania area. It will be housed at the University of Pittsburgh in the Swanson School of Engineering (SSoE) and will be a part of the Nanofabrication and Characterization Facility (NFCF) in the Peterson Institute of NanoScience and Engineering (PINSE). It will be linked to the electron microscopy facility in the Structural Biology department, School of Medicine. The NFCF is a user facility available to all national and international researchers. The broad visibility and access to this instrument will contribute to nano- and meso-scale science and technology, biology, energy and sustainability research and to the training of post-docs, graduate students and undergraduate students. This instrument will also be used in teaching courses in Electron Microscopy, Nano-characterization, Thin Films, Biomaterials, Nanomaterials and Nanotechnology. As a part of PINSE, it will contribute to the education of high school students and under-represented groups, especially African-American, as part of the NSF-Nanotechnology Undergraduate Education (NUE) outreach program and Pitt Engineering Career Access Program (PECAP) program, respectively. ******This award from the Major Instrumentation program will support the installation of the first Environmental Transmission Electron Microscope (ETEM) in the greater Western Pennsylvania area.

TEM is a powerful tool to visualize materials at the nanoscale and below. ETEM enables unique insights on the dynamic processing/structure/property relationships of nanomaterials with impact in a broad spectrum of science and engineering areas, such as oxidation, corrosion, catalysis, nano-processing, bio-mineralization, tissue engineering and drug delivery.

1337731Yang 技术摘要这项重大研究仪器奖支持购买环境透射电子显微镜 (ETEM)，这是一种高分辨率电子显微镜，具有简化的差动泵系统，允许将气体直接引入色谱柱。 作为传统的 TEM，该仪器将增强当前电子显微镜在教学、用户培训和研究方面的能力。在操作环境条件下可视化亚纳米级结构变化的能力将为许多材料问题带来重要的见解，例如掺杂剂和杂质对加工和腐蚀的影响、缺陷（位错、晶界和界面）迁移、热诱导相变、多相催化、纳米级功能材料以及一般材料的环境稳定性。 低加速电压最大限度地减少了氧化物和软材料的损坏，从而提供了可视化聚合物、组织工程、药物输送、生物材料和生物矿化动力学的能力。 这将是大宾夕法尼亚州西部地区的第一个 ETEM。 它将坐落于匹兹堡大学斯旺森工程学院 (SSoE)，并将成为彼得森纳米科学与工程研究所 (PINSE) 纳米制造和表征设施 (NFCF) 的一部分。它将与医学院结构生物学系的电子显微镜设施相连。 NFCF 是一个可供所有国内和国际研究人员使用的用户设施。 该仪器的广泛知名度和使用将有助于纳米和介观科学技术、生物学、能源和可持续性研究以及博士后、研究生和本科生的培训。该仪器还将用于电子显微镜、纳米表征、薄膜、生物材料、纳米材料和纳米技术等课程的教学。作为 PINSE 的一部分，它将分别作为 NSF 纳米技术本科教育 (NUE) 外展计划和皮特工程职业准入计划 (PECAP) 计划的一部分，为高中生和代表性不足群体（尤其是非裔美国人）的教育做出贡献。 ******该重大仪器计划的奖项将支持在大宾夕法尼亚州西部地区安装第一台环境透射电子显微镜 (ETEM)。该仪器将安置在匹兹堡大学斯旺森工程学院 (SSoE)，作为纳米制造和表征设施 (NFCF) 的一部分，该设施是一个可供所有国内和国际研究人员使用的用户设施。 TEM 是可视化纳米级及以下材料的强大工具。 ETEM 能够对纳米材料的动态加工/结构/性能关系产生独特的见解，对氧化、腐蚀、催化、纳米加工、生物矿化、组织工程和药物输送等广泛的科学和工程领域产生影响。 该仪器的广泛知名度和使用将有助于纳米和介观尺度的科学技术、生物学、能源和可持续发展研究以及博士后、研究生和本科生的教育。该仪器还将用于电子显微镜、纳米表征、薄膜、生物材料、纳米材料和纳米技术课程的教学。 它将分别作为 NSF 纳米技术本科教育外展计划和皮特工程职业准入计划的一部分，为高中生和弱势群体（尤其是非裔美国人）的教育做出贡献。
