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

DMR主要研究仪器计划的这一奖项将允许科学院购买扫描探针显微镜。该显微镜将使科学院的研究人员能够研究物理，化学和生物学领域的各种新颖的表面效应。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，以及侵蚀性气体自由基，稀酸和水对各种玻璃家族的腐蚀。 其他研究将侧重于表面特征对零价和低价金属还原转化水中污染物的机制的影响，以及海洋蠕虫形成生物水泥的影响。 第一个外部使用将进行电化学测量的胶体颗粒，已与聚氧乙烯酸酯官能化。超过10名本科生，从科及其相关的REU网站，每年将接受纳米科学技术的培训。从DMR的主要研究仪器计划这一奖项将允许科学院购买扫描探针显微镜。扫描探针显微镜将使研究人员能够在物理，化学和生物学方面开展新的工作。 显微镜将使研究人员能够看到玻璃中的微小特征如何散射光线，如磨砂窗格，以及水，酸和腐蚀性气体如何破坏玻璃表面。 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礁的方式，甚至在水下。 另一个项目将研究如何通过在微小颗粒（胶体）表面附着特殊分子来使其变得更有用。 显微镜还将帮助培养许多本科生在纳米科学技术，一个国家的重要性和日益增长的兴趣领域。

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.
