Acquisition of an Ultra-High-Vacuum Variable-Temperature Scanning Probe Microscope for the Study of Nanoscale Dynamics in Complex Materials and Education

以色列授予东北大学购买最先进的低温超高真空(UHV)扫描探针显微镜。在玻璃、聚合物、蛋白质、陶瓷和小型设备等复杂材料中，长度尺度上的性质波动在略大于原子尺度的范围内变得越来越重要。这些介观尺度的波动被认为是因为分子必须协同重排，这是许多系统中发生的一种重要但鲜为人知的现象。利用功能强大的新型纳米光谱仪将直接研究各种复杂材料中的纳米尺度的协同性，这需要最先进的低温超高真空(UHV)扫描探针显微镜。通过合作和体验式教育计划，本科生将利用这一最先进的仪器参与研究，获得宝贵的纳米科学经验，使他们能够为未来重要的纳米技术做出贡献。***

0075931IsraeloffAn award is made to the Northeastern University for the acquisition of state-of-the-art low-temperature ultra-high-vacuum (UHV) scanning-probe-microscope. Fluctuations in properties on a length scale somewhat larger than atomic scale are increasingly important in complex materials such as glasses, polymers, proteins, ceramics, and small devices. These mesoscopic scale fluctuations are believed to arise because molecules must rearrange cooperatively, an important but poorly understood phenomena occurring in many systems. Nanoscale cooperativity will be directly studied in various complex materials using powerful new nanoscale spectroscopies which require a state-of-the-art low-temperature ultra-high-vacuum (UHV) scanning-probe-microscope. Through cooperative and experiential education programs, undergraduates will participate in research with this state-of-the-art instrument, gaining valuable nano-science experience and enabling them to contribute to important nano-technologies of the future. ***
