This Major Research Instrumentation RUI grant supports state-of-the-art nanoindentation equipment for Grinnell College to conduct research on the fundamental mechanisms of friction at the molecular level. The specific equipment, a Hysitron TriboScope nanoindenter, is a probe device that simultaneously measures normal and lateral forces, probe displacements, and contact area. It can be interfaced with the Digital Instruments control base already existing at Grinnell College. Student researchers will make use of the equipment. Grinnell College's Physics Department graduates 10 to 20 physics majors per year and has attained unique success in bringing women and minority students into physics. Half of Grinnell's physics graduates pursue graduate study in the sciences. The department views student-faculty research as an extremely valuable part of an undergraduate physics education, benefiting both students and faculty alike. The self-assembled monolayer systems to be studied using this nanoindenter show promise as lubricants for a new generation of microdynamic devices. They are also well-controlled experimental and theoretical model systems for investigating the energy dissipation mechanisms underlying friction.

这项主要的研究仪器RUI Grant支持Grinnell College的最先进的纳米凹痕设备，以研究分子水平的摩擦基本机制。特定设备是一种荧光板锥形纳米Indententer，是一种探针设备，可同时测量正常和侧向力，探针位移和接触面积。它可以与格林内尔学院已经存在的数字仪器控制基础接口。学生研究人员将利用设备。格林内尔学院的物理系每年10至20个物理专业的毕业生，在将妇女和少数族裔学生带入物理学方面取得了独特的成功。格林内尔（Grinnell）的一半物理学毕业生在科学领域进行研究生研究。该部门将学生教师研究视为本科物理教育的极为宝贵的一部分，使学生和教职员工都受益。使用这种纳米Indententer进行研究的自组装单层系统，作为新一代微型动力设备的润滑剂的希望。它们也是控制摩擦潜在的能量耗散机制的实验和理论模型系统。
