MRI: Acquisition of a Transmission Electron Microscope for In-situ Studies of Soft and Hard Matter

该主要研究仪器奖支持在北卡罗莱纳州立大学（NCSU）购置一台透射电子显微镜（TEM），用于研究广泛的跨学科材料。显微镜使跨学科的研究，能源储存和转换，生物相容性，环境调解，和材料表现出奇异的性质，如超导性。虽然TEM通常在室温和高真空下操作，但该显微镜可以在从低温到一千摄氏度的温度范围内，在各种液体中或暴露于各种气体中对样品进行成像。这些条件可以与材料运行的条件密切匹配，从而提供新的科学见解。TEM被整合到NCSU的几个活动中，包括让K-12学生有机会亲自体验科学仪器。显微镜的结果也被纳入了一个核心的教育推广计划，使公众通过不令人生畏的艺术媒介接触到原子分辨率电子显微镜。该主要研究仪器奖支持在北卡罗莱纳州立大学（NCSU）购置一台透射电子显微镜（TEM），用于在发生动态现象的条件下研究硬物质和软物质。该仪器通过在低温（低至低温）、加热、偏置、机械加载、气体和液体等各种条件下实现快速原位成像，促进了研究三角的新研究。此外，还配备了高速摄像机来捕捉这些实验过程中的详细结构变化。这些能力，再加上捕获光谱和三维数据的能力，将使研究人员能够在与材料特性相关的条件下，以大大提高的时间分辨率，获得新的原子尺度的见解，从而加速智力产出。该仪器可以研究广泛的材料，并集成到美国国家科学基金会资助的研究三角纳米技术网络中，此次收购将影响北卡罗来纳州NCSU以及其他部门的研究。

This Major Research Instrumentation award supports the acquisition of a transmission electron microscope (TEM) at North Carolina State University (NCSU) equipped to study a broad range of interdisciplinary materials. The microscope enables interdisciplinary research into energy storage and conversion, biological compatibility, environmental mediation, and materials exhibiting exotic properties such as superconductivity. While a TEM is usually operated at room temperature and under high vacuum, this microscope enables imaging with the sample at temperatures ranging from cryogenic to a thousand degrees Celsius, in a variety of liquids, or exposed to various gases. These conditions can closely match those where the materials operate and thus provide new scientific insights. The TEM is integrated into several activities at NCSU including the opportunity for K-12 students to experience scientific instrumentation first hand. Results from the microscope are also incorporated into a centerpiece educational outreach program that exposes the general public to atomic resolution electron microscopy through the unintimidating medium of art.This Major Research Instrumentation award supports the acquisition of a transmission electron microscope (TEM) at North Carolina State University (NCSU) equipped to investigate hard and soft matter at conditions where dynamic phenomena occur. The instrument catalyzes new research in the Research Triangle by enabling fast in situ imaging in a variety conditions including low temperatures (down to cryogenic), heating, biasing, mechanical loading, gas, and liquid. Further, a high-speed camera is equipped to capture detailed structural changes during these experiments. These capabilities, in combination with the capability to capture spectroscopic and three-dimensional data, will accelerate intellectual output by empowering researchers to make new, atomic scale insights, with greatly improved temporal resolution, and at conditions relevant to material properties. With a broad spectrum of materials that can be studied with the instrument, and integration into the NSF funded Research Triangle Nanotechnology Network, the acquisition will impact research across departments at NCSU, in North Carolina, and beyond.
