这一重大研究仪器(MRI)奖支持收购具有微尺度振动和地形表征能力的一体化光学测量工作站仪器。该工具将加强西部山区的研究和教育能力，并加强区域产业和大学之间的合作。它将促进涉及添加剂制造、材料科学、生物医学工程和量子物理的跨学科和基础研究。该仪器集成到课程项目和研究实验室实习中，将加强博伊西州立大学科学、技术、工程和数学(STEM)的多样性和保留率。该工具还将用于爱达荷州K-12学生和教育工作者的外联活动，以加强STEM的招聘。该仪器由一个激光多普勒振动仪和一个白光干涉仪组成，前者可测量高达2.4 GHz的亚皮米量级的振动，后者可测量三维表面形貌，分辨率可达亚纳米级。激光多普勒振动仪可以可视化声波在各种材料中的传播，包括合金、陶瓷、软组织、颗粒复合材料和印刷多孔膜。对这些材料的变革性研究可能会带来用于核反应堆的先进超声波传感器、用于组织工程的创新生物支架、高效嵌入式神经刺激器和新颖的量子信息传递方法。白光干涉仪可以实时检测显微组织的变形。与定制的电磁铁或热源一起，该仪器将提供前所未有的智能材料的材料特性，如磁致伸缩材料和磁性形状记忆合金。对这些多物理和多功能材料的基本了解将导致用于结构健康监测或药物输送的新设备。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This Major Research Instrumentation (MRI) award supports the acquisition of an all-in-one optical measurement workstation instrument with micro-scale vibration and topography characterization capabilities. The instrument will enhance research and education capacity in the mountain west and enhance collaborations at regional industries and universities. It will catalyze interdisciplinary and fundamental research involving additive manufacturing, materials science, biomedical engineering, and quantum physics. Integrated into course projects and research lab internships, the instrument will enhance the science, technology, engineering, and math (STEM) diversity and retention at Boise State University. The instrument will also be used for outreach activities with K-12 students and educators in the state of Idaho, to enhance STEM recruitment. The instrument consists of a laser doppler vibrometer enabling sub-picometer magnitude vibration measurement up to 2.4 GHz and a white light interferometer enabling three-dimensional surface topography down to sub-nanometer resolution. The laser doppler vibrometer can visualize acoustic wave propagation in various materials, including alloys, ceramics, soft tissues, particulate composites, and printed porous films. Transformative research on these materials will potentially lead to advanced ultrasonic sensors for nuclear reactors, innovative bioscaffolds for tissue engineering, efficient embedded neuro stimulators, and novel quantum information delivery methods. The white light interferometer can detect microstructure morphing in real-time. Along with customized electromagnets or heat sources, the instrument will provide unprecedented material properties of smart materials, such as magnetostrictive materials and magnetic shape memory alloys. The fundamental understanding of these multiphysics and multifunctional materials will result in new devices for structural health monitoring or drug delivery.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.
