项目摘要
This Major Research Instrumentation (MRI) award supports the acquisition of advanced instrumentation for a user-based in-situ Transmission Electron Microscopy (TEM) testing facility at the University of Missouri. The instrumentation will enable dynamic testing of diverse samples while imaging. This includes a gas-phase test cell with residual gas analyzer, a liquid-phase test cell with electrochemical capabilities, and a vacuum cell with heating and biasing capabilities. To eliminate the undesirable image drift that traditionally stifles in-situ TEM experiments, the instrument will also provide active image stabilization. The instrument suite will be installed in the University of Missouri Electron Microscopy Center and will be accessible for educational and industrial users.The suite of instrumentation has diverse application in biological and materials-based research. Example activities include the following projects: The activity of Pt electrocatalysts and carbon nanotube catalyst systems will be examined with atomic resolution at elevated temperatures using the Protochips Atmosphere system. The on-board residual gas analyzer will provide a quantitative measurement of gas composition change as catalyst particles activate and de-activate. The self-assembly of colloidal nanoparticles and biomolecules will be enabled by the Protochips Poseidon Select. Precise three-dimensional tracking of individual particles is enabled by the Protochips Axon Synchronicity system. The in-operando formation of interphase materials at cathode/solid electrolyte junctions under electrical current will be examined using the Fusion Select system. All experiments will benefit from the dynamic hardware and software-enabled stabilization provided by the Protochips Axon Synchronicity.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该重大研究仪器(MRI)奖支持密苏里州大学基于用户的原位透射电子显微镜(TEM)测试设施的先进仪器采购。该仪器将能够在成像的同时对各种样品进行动态测试。这包括带有残余气体分析仪的气相测试单元、具有电化学功能的液相测试单元以及具有加热和偏置功能的真空单元。为了消除传统上扼杀原位TEM实验的不期望的图像漂移,该仪器还将提供主动图像稳定。该仪器套件将安装在密苏里州大学电子显微镜中心,并将访问教育和工业用户。该仪器套件在生物和材料为基础的研究有不同的应用。活动实例包括以下项目:将使用Protochips Atmosphere系统在高温下以原子分辨率检查Pt电催化剂和碳纳米管催化剂系统的活性。车载残余气体分析仪将提供催化剂颗粒活化和失活时气体成分变化的定量测量。胶体纳米颗粒和生物分子的自组装将通过Protochips Poseidon Select实现。Protochips Axon Synchronicity系统可对单个颗粒进行精确的三维跟踪。将使用Fusion Select系统检查电流下阴极/固体电解质结处的界面材料的操作中形成。所有实验都将受益于Protochips Axon Synchronicity提供的动态硬件和软件支持的稳定性。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
