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.

该主要研究仪器奖支持在北卡罗来纳州州立大学（NCSU）购买透射电子显微镜（TEM），用于研究广泛的跨学科材料。该显微镜使跨学科的研究进入能量储存和转换，生物相容性，环境调解，并表现出奇异的性质，如超导材料。虽然TEM通常在室温和高真空下工作，但这种显微镜可以在低温至1000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的几项活动中，包括让K-12学生有机会亲身体验科学仪器。 从显微镜的结果也被纳入一个核心的教育推广计划，暴露给公众原子分辨率电子显微镜通过艺术的unmilling介质。这个主要的研究仪器奖支持收购透射电子显微镜（TEM）在北卡罗来纳州州立大学（NCSU）配备调查硬和软物质的条件下发生动态现象。该仪器通过在各种条件下实现快速原位成像来促进三角研究中的新研究，包括低温（低至低温），加热，偏压，机械加载，气体和液体。此外，还配备了高速相机，以捕捉这些实验期间的详细结构变化。 这些能力与捕获光谱和三维数据的能力相结合，将通过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，进行新的原子尺度见解，来加速智力输出。随着广泛的材料，可以用仪器进行研究，并集成到NSF资助的研究三角纳米技术网络，收购将影响跨部门的研究在NCSU，在北卡罗来纳州，和超越。
