MRI: A Scanning Probe Microscope for Undergraduate Research at Coe College

这项来自DMR主要研究仪器项目的奖励将允许科学院购买一台扫描探针显微镜。该显微镜将允许科学院的研究人员在物理、化学和生物学领域研究各种新的表面效应。研究人员将研究粗糙玻璃表面的光散射，硼硅酸盐和硼钒酸盐的相分离，以及侵略性气体自由基，稀酸和水对各种玻璃族的腐蚀。其他研究将集中于表面特征对零价和低价金属对水中污染物还原转化机制的影响，以及海蠕虫对生物水泥形成的影响。第一次外部使用将对用多金属氧酸盐功能化的胶体颗粒进行电化学测量。来自Coe及其相关REU站点的十多名本科生每年将接受纳米科学技术的培训。这项来自DMR主要研究仪器项目的奖励将允许科学院购买一台扫描探针显微镜。扫描探针显微镜将使研究人员在物理、化学和生物学方面开展新的工作。这台显微镜将使研究人员能够看到玻璃上的微小特征是如何散射光线的，比如磨砂玻璃，以及水、酸和腐蚀性气体是如何破坏玻璃表面的。在环境化学项目中，PI将观察铁氧化对水中污染物反应的作用。显微镜将使他们能够研究海蠕虫将沙粒粘合在一起形成海洋珊瑚礁的方式，即使在水下也是如此。另一个项目将研究微小颗粒（胶体）如何通过在其表面附着特殊分子而变得更有用。这台显微镜还将帮助培养许多大学生掌握纳米科学技术，这是一个具有国家重要性且日益引起人们兴趣的领域。

This award from the Major Research Instrumentation program in DMR will allow Coe College to purchase a scanning probe microscope. The microscope will allow Coe College researchers to study a variety of novel surface effects in the areas of physics, chemistry, and biology. The researchers will look at light scattering by roughened glass surfaces, phase separation in borosilicates and borovanadates, and corrosion of varied glass families by aggressive gas radicals, dilute acids, and water. Other studies will focus on the effect of surface features on the mechanisms of reductive transformations of pollutants in water by zero- and low-valent metals, and on the formation of biocements by sea worms. The first external use will carry out electrochemical measurements on colloidal particles that have been functionalized with polyoxometalates. Over ten undergraduate students, from Coe and its associated REU site, will receive training in the techniques of nanoscience every year.This award from the Major Research Instrumentation program in DMR will allow Coe College to purchase a scanning probe microscope. The scanning probe microscope will allow the researchers to carry out new work in physics, chemistry, and biology. The microscope will permit the researchers to see how tiny features in glass scatter light, like in frosted panes, and how water, acids, and corrosive gases can also damage glass surfaces. In the environmental chemistry project the PI's will observe the role of iron oxidation on the reactions of pollutants in water. The microscope will allow them to investigate the way that sea worms cement sand grains together to make sea reefs, even underwater. Another project will study how tiny particles (colloids) can be made more useful by attaching specialized molecules on their surface. The microscope will also help train many undergraduates in the techniques of nanoscience, an area of national importance and growing interest.
