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. ***

0075931Israeloff 东北大学因购买最先进的低温超高真空 (UHV) 扫描探针显微镜而获奖。在玻璃、聚合物、蛋白质、陶瓷和小型设备等复杂材料中，比原子尺度稍大的长度尺度上的性能波动变得越来越重要。 这些介观尺度波动被认为是因为分子必须协同重新排列而产生的，这是许多系统中发生的一种重要但人们知之甚少的现象。将使用强大的新型纳米级光谱技术直接研究各种复杂材料的纳米级协同性，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项目，本科生将使用这种最先进的仪器参与研究，获得宝贵的纳米科学经验，并使他们能够为未来的重要纳米技术做出贡献。 ***
