项目摘要

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中的两个计划共同资助：冷凝物理物理（CMP）和陶瓷（CER）。非技术描述：新颖的眼镜对新一代设备，平面屏幕和探测器很重要。候选眼镜正在与世界各地的许多团体（例如，在巴西，加拿大，日本和英国）合作，在Coe College进行准备和描述。玻璃制剂通常是非传统的，并且使用快速冷却（约1,000,000 c/s），激光空气驱动至近3000 c以及替代化学方法。这些眼镜的表征探测了原子结构和相关的物理特性。使用光谱学阵列确定原子结构。重要的物理特性包括玻璃软化温度，原子对空间的有效使用，玻璃形成的组成极限以及电导率。项目的重点是医学玻璃，开发用于医疗和颗粒探测器的玻璃，制造玻璃复合材料，这些玻璃复合材料抑制细菌，以及持续数小时的黑暗晶体。更广泛的影响包括培训大约50名本科生和高中生，并与当地学校和整个校园接触。根据历史，预计这些学生中有近30名将继续参加研究生课程。学生在材料科学，计算机科学，电气工程以及其他几个工程和物理领域的工业和国家实验室中为国家服务。技术详细信息：在光纤和显示器的时代，正在使用滚筒，激光空气平局和包括溶胶 - 凝胶方法在内的化学溶液技术研究创新的眼镜。这些方法允许用不情愿的配方制作玻璃，包括二元和三元钒酸盐玻璃。这些玻璃很重要，是探测器中的导电玻璃，高碱含量玻璃杯用于杀菌的用途，以及闪烁的碱和碱性硼硅酸盐玻璃杯，这些玻璃杯结合了ZnO和P-Terphenyl等无机和有机粉刺剂。对学生进行了多种技术的训练，包括核磁共振，拉曼和傅立叶变换红外光谱，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的飞行时间质谱。此外，学生使用120个核心计算机系统采用分子动力学模拟。更广泛的影响包括对约40名COE学院本科生进行的广泛研究培训和另外十名高中学生。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，被认为值得通过评估来获得支持。
