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.

DMR主要研究仪器计划的奖项将使Coe College可以购买扫描探针显微镜。显微镜将允许COE学院的研究人员研究物理，化学和生物学领域的各种新型表面影响。研究人员将通过粗糙的玻璃表面，硼硅酸盐和硼烷酸酯的相位分离以及通过侵略性气体自由基，稀酸和水对变化的玻璃家族进行腐蚀。 其他研究将侧重于表面特征对通过零和低价值金属以及海蠕虫形成生物焦的水在水中还原剂还原性转化的作用。 第一个外部用途将对已经用多氧钙化功能化的胶体颗粒进行电化学测量。来自COE及其相关的REU网站的十多名本科生将接受每年纳米科学技术的培训。DMR的主要研究仪器计划的奖项将使Coe College允许Coe College购买扫描探针显微镜。扫描探针显微镜将使研究人员能够从事物理，化学和生物学方面的新工作。 显微镜将使研究人员能够看到玻璃散射光中的微小特征，例如磨砂窗格，以及水，酸和腐蚀性气体如何也会损坏玻璃表面。 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水泥沙粒的方式，即使是水下，也可以制造海礁。 另一个项目将研究如何通过将专门分子在其表面上附着小颗粒（胶体）更有用。 显微镜还将帮助培训许多本科生的纳米科学技术，这是国家重要性和兴趣日益增长的领域。
