MRI: Acquisition of an Advanced Nanoindentation System for Multidisciplinary Research and Training

这一重大研究仪器奖支持收购最先进的纳米压痕系统，以促进基础研究，从而带来更具弹性的基础设施、新材料、医疗和能源生产的进步，以及改进的车辆和飞机设计。纳米压痕是小规模测量力学的重要工具；这种仪器具有华盛顿大学(UW)或太平洋西北地区所不具备的纳米机械表征能力。它将在威斯康星州大学和合作伙伴学校实现多学科研究、教育和推广。每年将有10多名研究助理和50多名研究生研究人员接受该仪器的培训，极大地扩大了具有纳米机械表征经验的下一代研究人员。该系统将促进四个地区性伙伴机构的教育项目，以及伯克博物馆一年一度的“与哺乳动物相遇”家庭日和华盛顿大学工程学院的“工程发现日”的公共宣传活动。这些活动增进了公众的了解，有助于吸引下一代投身科学、技术、工程和数学领域。Hysitron TI 980摩擦压痕仪具有低至1 nN力和0.01 nm位移的超低噪音底板，配备了强大的多头底座，能够无缝操作多种测量模式，如纳米压痕、纳米划痕和纳米耳。与高温、高/低负载、导电和水下压痕选项相补充，该系统将使研究人员能够在能源和健康方面从纳米和分子水平追求先进知识，在航空航天和基础设施更新方面追求微观和更大范围的先进知识。它将使工程师能够研究生物、水泥和颗粒材料、复合材料、金属和聚合物，医学、健康科学和牙科研究人员可以研究细胞、组织和整个器官的生物力学。它将有助于对金属多层膜的脉冲激光强化、纳米螺旋铁磁机器人驱动器的特性以及半导体有机聚合物、高温复合材料和聚合物复合材料传感器的机械性能的基本了解。该仪器还将使旨在延长下一代锂离子电池电极材料耐用性的研究成为可能。最后，将有可能就与年龄相关的硬组织降解、改善与硬组织的粘附性以及由釉原蛋白衍生多肽辅助的硬组织再矿化的战略进行新的研究。该系统将成为华盛顿大学和大太平洋西北地区研究人员的主要地区性资源。

This Major Research Instrumentation award supports the acquisition of a state-of-the-art nanoindentation system to catalyze fundamental research leading to more resilient infrastructure, novel materials, advances in medical treatment and energy production, and enhanced vehicle and aircraft design. Nanoindentation is an important tool for measuring mechanics at a small scale; this instrumentation has nanomechanical characterization capabilities that are not available at the University of Washington (UW) or the Pacific Northwest. It will enable multidisciplinary research, education and outreach at the UW and partner schools. More than 10 research associates and 50 graduate researchers will be trained on the instrument annually, greatly expanding the next generation of researchers with nanomechanical characterization experience. The system will facilitate educational programs at four regional partner institutions and public outreach events in the annual "Meet the Mammals" family day at the Burke Museum and "Engineering Discovery Days" of the UW College of Engineering. These activities enhance public understanding and help to attract the next generation to careers in science, technology, engineering and math. The Hysitron TI 980 Triboindenter, with an ultra-low noise floor down to 1 nN force and 0.01 nm displacement, is equipped with a powerful multi-head base capable of seamlessly operating multiple measurement modes such as nanoindentation, nanoscratch, and nanowear. Complemented with high temperature, high/low load, conductive and submerged indentation options, the system will enable researchers to pursue advanced knowledge from the nano and molecular levels in energy and health, to the micro and larger scales in aerospace and infrastructure renewal. It will enable engineers to study biological, cementitious and granulated materials, composites, metals and polymers, and medical, health science and dental researchers to investigate the biomechanics of cells, tissues to whole organs. It will facilitate fundamental understanding in pulsed-laser strengthening of metallic multi-layers, the properties of nanohelical ferromagnetic robotic actuators, and the mechanical performance of semiconducting organic polymers, high temperature composites, and polymer composite sensors. The instrument will also enable studies aimed at extending the durability of next-generation li-ion battery electrode materials. Lastly, new research will be possible regarding strategies for age-related degradation of hard tissues, for improving adhesive bonds to hard tissues, and for remineralizing hard tissues assisted by amelogenin-derived peptides. The system will become a major regional resource to researchers at the University of Washington and the greater Pacific Northwest.
