Non-Technical SummaryThis grant supports research on glass science for undergraduates at Coe College in Cedar Rapids, IA. The research plan is focused on discovering new glass families with novel properties and structure. Some examples of these glasses are of potential use in batteries. Students use various ways to rapidly quench liquids to glasses designed and built in-house. Structure is found using various forms spectroscopies. Properties include thermal and optical measurements as well as density, hardness, and electrical and ionic conductivity. Computer simulations and theoretical models are frequently done. Broader impacts are of vital importance to this project. The foremost broader impact is that these undergraduates, rapidly increasing in diversity, gain several years of research experience. This serves the national interest and helps provide the nation with urgently needed highly trained technical staff as well as provide a substantial source of well-educated students for graduate school. Another important broader impact is that Coe College is now a hub of undergraduate research expertise in glass science. Knowledge about this undergraduate research program is being systematically shared with faculty at other higher education institutions, including several minority serving ones. Also, as part of Coe’s REU program, students from research-poor colleges and high-school teachers join this research. High-school students also join this research program each summer. Technical SummaryThis grant supports research on novel oxide glasses by undergraduate students at Coe College. The research plan is to extend glass formation to new compositions in a variety of potential binary and ternary glass forming systems that are currently understudied. Some examples of these systems include alkali tellurites and vanadates where there are promising results from this lab. For example, invert tellurite glasses have been formed with up to 65 molar percent sodium oxide. For this project, twin-roller quenching is used on custom designed and built instruments made here by students and faculty. Properties and atomic structure are measured and compared. These techniques include thermal (Tg, Tx, Tm, and fragility), optical (TOF-MS, laser levitation studies of glass formation and viscosity, Raman spectroscopy, and XRD) properties as well as density, hardness, and ionic conductivity. With collaborators NMR, x-ray, and neutron scattering studies are carried out. Also, molecular dynamics simulations and topological constraint theory are employed to determine compositionally changing properties from structural models and knowledge of bond constraints. Broader impacts are of vital importance to this project. The foremost broader impact is that many undergraduates gain multiple years of publishable research experience. This provides the nation with trained technical staff as well as provide a source of well-educated graduate students. Another important broader impact is that Coe College continues to serve as hub of undergraduate research expertise. This knowledge is being systematically shared with other higher education institutions, including several minority serving ones. Workshops, presentations at technical conferences, and mutual visits also occur. Outreach to elementary schools and high schools happens often. High-school students join this research program each summer. Students from research-poor colleges and teachers join this research each summer as part of Coe’s REU program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术性摘要该补助金支持爱荷华州锡达拉皮兹科学院本科生的玻璃科学研究。该研究计划的重点是发现具有新特性和结构的新玻璃家族。 这些玻璃的一些例子在电池中具有潜在的用途。学生使用各种方法快速淬火液体玻璃设计和建造的内部。 使用各种形式的光谱学发现结构。性能包括热和光学测量以及密度、硬度、电导率和离子电导率。经常进行计算机模拟和理论模型。更广泛的影响对这个项目至关重要。最重要的更广泛的影响是，这些本科生，迅速增加的多样性，获得几年的研究经验。这符合国家利益，有助于为国家提供急需的训练有素的技术人员，并为研究生院提供大量受过良好教育的学生。另一个重要的更广泛的影响是，科学院现在是玻璃科学本科研究专业知识的中心。有关这一本科研究计划的知识正在系统地与其他高等教育机构的教师分享，包括几个少数民族服务机构。此外，作为科的REU计划的一部分，来自研究贫困大学的学生和高中教师加入这项研究。高中生每年夏天也参加这个研究项目。技术摘要该补助金支持科学院本科生对新型氧化物玻璃的研究。该研究计划是将玻璃形成扩展到目前研究不足的各种潜在二元和三元玻璃形成系统中的新组合物。这些系统的一些例子包括碱金属亚碲酸盐和钒酸盐，其中有来自本实验室的有希望的结果。例如，反相亚碲酸盐玻璃已经用高达65摩尔%的氧化钠形成。在这个项目中，双辊淬火用于学生和教师在这里定制设计和制造的仪器。性质和原子结构的测量和比较。这些技术包括热（Tg、Tx、Tm和脆性）、光学（TOF-MS、玻璃形成和粘度的激光悬浮研究、拉曼光谱和XRD）性质以及密度、硬度和离子电导率。与合作者进行NMR，X射线和中子散射研究。此外，分子动力学模拟和拓扑约束理论，以确定组成变化的性质，从结构模型和知识的债券约束。更广泛的影响对这个项目至关重要。最重要的更广泛的影响是，许多本科生获得多年的可持续研究经验。这为国家提供了训练有素的技术人员，并提供了受过良好教育的研究生的来源。另一个重要的更广泛的影响是，科学院继续作为本科研究专业知识的中心。目前正在与其他高等教育机构，包括几所少数民族高等教育机构系统地分享这方面的知识。研讨会、技术会议上的演讲和相互访问也会发生。小学和高中的外联活动经常发生。高中生每年夏天都参加这个研究项目。作为科的REU计划的一部分，每年夏天，来自研究薄弱的大学的学生和教师都会参加这项研究。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
