MRI: Acquisition of a High Energy X-ray Tomography Scanner for Multidisciplinary Research and Education The objective of this Major Research Instrumentation (MRI) award is to acquire a versatile, robust, high energy, and high resolution X-ray microtomography (micro-CT) system that facilitates nondestructive mapping of the internal structure of a variety of materials enhancing multidisciplinary research and education at the University of Vermont (UVM). Since the introduction of computer-based X-ray tomographic imaging in the medical services field about 40 years ago, X-ray computed tomography is now applied to the nondestructive study of various natural, historic and engineered materials in the fields of engineering, geology, materials science, biology, and geo-energy, among others. This state-of-the-art technology provides non-destructive, high resolution, 3D imaging of materials that enables researchers to tackle many contemporary, previously intractable, fundamental and applied research questions related to infrastructure security, safety, health, and energy, with direct benefits to the society. The instrument will support research and educational activities of eighteen investigators from diverse fields of civil, environmental, mechanical, electrical and bio engineering, plant and soil science, geology, historic preservation, medicine and materials science. With this initial set of users and research applications for the instrument, it is believed that the impact of the acquisition of this micro-CT will be substantial for providing powerful new capabilities for researchers and their students and will thus lead to new on- and off-campus research and training collaborations. The micro-CT allows researchers to examine the effects of loading, temperature fluctuations, fluid injections and how the fluids are absorbed by different materials. It will enable the UVM researchers to perform transformative basic and applied research and education related to: transport, mechanical and thermal behavior of a variety of porous media (soils, rocks, building materials); characterization of geological materials; characterization of plant and soil community structure; and materials research ranging from historic to smart materials and bio and bio-inspired materials. The instrument will also enhance curricular offerings across the campus. Educational modules based on the results obtained using the micro-CT will be incorporated into courses such as Materials Engineering, Soil Mechanics, Groundwater Hydrology, Geo-energy Systems, Physics of Flow and Transport through Porous Media, Microstructures (Geology), Biomechanics, Transport Processes, and Fundamental of Soil Sciences and Soil Water Movement, among others.

磁共振成像：获得用于多学科研究和教育的高能X射线断层扫描仪该重大研究仪器（MRI）奖项的目的是获得一种多功能，强大，高能和高分辨率的X射线显微断层扫描（micro-CT）系统，该系统有助于对各种材料的内部结构进行无损测绘，从而增强佛蒙特大学（UVM）的多学科研究和教育。自从大约40年前在医疗服务领域引入基于计算机的X射线断层摄影成像以来，X射线计算机断层摄影现在被应用于工程、地质学、材料科学、生物学和地球能源等领域中的各种自然、历史和工程材料的无损研究。这种最先进的技术提供了非破坏性的，高分辨率的材料3D成像，使研究人员能够解决许多与基础设施安全，安全，健康和能源相关的当代，以前棘手的基础和应用研究问题，并直接造福于社会。该仪器将支持来自土木、环境、机械、电气和生物工程、植物和土壤科学、地质学、历史保护、医学和材料科学等不同领域的18名研究人员的研究和教育活动。有了这套仪器的初始用户和研究应用程序，相信收购这种微型CT的影响将是巨大的，为研究人员和他们的学生提供强大的新功能，从而导致新的校内和校外研究和培训合作。微型CT允许研究人员检查负载，温度波动，液体注射以及不同材料如何吸收液体的影响。 它将使UVM研究人员能够进行与以下方面相关的变革性基础和应用研究和教育：各种多孔介质（土壤，岩石，建筑材料）的运输，机械和热行为;地质材料的表征;植物和土壤群落结构的表征;以及从历史到智能材料和生物和生物启发材料的材料研究。该工具还将加强整个校园的课程设置。基于使用微型CT获得的结果的教育模块将被纳入材料工程，土壤力学，地下水水文学，地球能源系统，通过多孔介质的流动和运输物理学，微结构（地质学），生物力学，运输过程，土壤科学和土壤水运动基础等课程。
