This project is jointly funded by two Programs in the Division of Materials Research: Condensed Matter Physics (CMP) and Ceramics (CER).NON-TECHNICAL DESCRIPTION: Novel glasses are important for new generations of devices, flat screens, and detectors. Candidate glasses are being prepared and characterized at Coe College in collaboration with many groups around the world (e.g., in Brazil, Canada, Japan, and the United Kingdom). The glass preparations are often non-traditional and use rapid cooling (about 1,000,000 C/s), laser aero-levitation to nearly 3000 C, and alternative chemical approaches. The characterization of these glasses probe the atomic structure and related physical properties. The atomic structure is identified using an array of spectroscopies. Physical properties that are important include the glass softening temperature, the efficient use of space by the atoms, the compositional limits for glass formation, and electrical conductivity. Projects focus on glasses in medicine, developing conducting glasses for medical and particle detectors, manufacturing glass composites that inhibit bacteria, and glow-in-the-dark crystals that last hours. Broader impacts include the training of about 50 undergraduate and high school students and reaching out to local schools and across campus. Based on history, it is anticipated that nearly 30 of these students will continue into graduate programs. Students serve the nation in industry and national labs in materials science, computer science, electrical engineering, and several other areas of engineering and physics. TECHNICAL DETAILS: In an age of fiber optics and displays, innovative glasses are being studied using roller-quenching, laser aero-levitation, and chemical solution techniques including sol-gel methods. These approaches allow glasses to be made with reluctant formulations including binary and ternary vanadate glasses. These glasses are important as conductive glasses in detectors, high alkali content borate glasses for bactericidal uses, and scintillating alkali and alkaline-earth borosilicate glasses that incorporate inorganic and organic scintillators such as ZnO and P-terphenyl. Students are trained in several techniques including nuclear magnetic resonance, Raman and Fourier transform infrared spectroscopies, neutron scattering, atomic force microscopy, X-ray diffraction, electron microscopy, and laser induced time-of-flight mass spectroscopy. Also, students employ molecular dynamics simulations of structure using a 120 core computer system. Broader impacts include the extensive research training of ~40 Coe College undergraduate students and additional ten high school students.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.

该项目由材料研究部的两个项目共同资助：凝聚态物理（CMP）和陶瓷（CER）。非技术描述：新型玻璃对于新一代设备、平板屏幕和探测器非常重要。候选眼镜正在准备和表征在科学院与世界各地的许多团体（例如，巴西、加拿大、日本和英国）。玻璃制备通常是非传统的，并使用快速冷却（约1，000，000 C/s），激光空气悬浮到近3000 C，以及替代化学方法。这些玻璃的表征探测了原子结构和相关的物理性质。原子结构是用一系列光谱来鉴定的。重要的物理性质包括玻璃软化温度、原子对空间的有效利用、玻璃形成的组成限制和电导率。 项目集中在医学玻璃，开发用于医疗和粒子探测器的导电玻璃，制造抑制细菌的玻璃复合材料，以及持续数小时的夜光晶体。更广泛的影响包括培训大约50名本科生和高中生，并深入当地学校和整个校园。 根据历史，预计这些学生中有近30人将继续攻读研究生课程。学生在材料科学，计算机科学，电气工程和其他几个工程和物理领域的工业和国家实验室服务于国家。 技术规格：在光纤和显示器的时代，正在使用辊淬火、激光空气悬浮和化学溶液技术（包括溶胶-凝胶法）研究创新玻璃。这些方法允许用包括二元和三元钒酸盐玻璃的不情愿配方来制造玻璃。这些玻璃作为探测器中的导电玻璃、用于杀菌用途的高碱含量硼酸盐玻璃以及掺入无机和有机增透剂如ZnO和对三联苯的增透碱和碱土硼硅酸盐玻璃是重要的。 学生接受几种技术的培训，包括核磁共振，拉曼和傅里叶变换红外光谱，中子散射，原子力显微镜，X射线衍射，电子显微镜和激光诱导飞行时间质谱。此外，学生使用120核心计算机系统进行结构的分子动力学模拟。更广泛的影响包括约40名科学院本科生和另外10名高中生的广泛研究培训。该奖项反映了NSF的法定使命，并被认为值得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来支持。
