RUI: Comprehensive Property Measurements and Structure Relationships in Various Glass Systems over Extreme Compositional Ranges

这个项目将涉及至少15名科学院本科生参与一些玻璃科学项目。本研究的目的是找出一些重要玻璃的原子级结构与这些玻璃所表现出的物理性质之间的关系，这些玻璃有些以前从未被描述过，有些具有商业价值。短程原子结构将使用各种技术来确定，包括磁共振、光谱学和中子散射。与原子排列有关的物理性质包括密度、光传输、软化温度和玻璃形成极限。这项研究的一个重要方面是，作为一个正在进行的大型国际合作研究这些眼镜的一部分，他们将获得工作经验，这将有利于并为有关本科生提供额外的研究培训。这项研究将包括确定各种基本的、新颖的和商业上有趣的玻璃系统的定量结构和性能关系。待研究的玻璃族包括碱硼酸盐、碱硅酸盐、碱硼硅酸盐、碱锗酸盐、铅铋氧化物基重金属氧化玻璃、碱钒酸盐、磷酸盐、氯化玻璃等。一些互补的光谱技术，包括新型核磁共振、动态角旋转、核四极共振、卢瑟福-阿普尔顿实验室的弹性和非弹性中子散射、红外和拉曼散射将被使用。要检查的物理性质包括：密度、玻璃化转变温度、光学特性和玻璃形成极限。这项工作是公认的世界范围合作的一部分。该项目的另一个关键方面是对本科生的严重依赖；至少15名来自科学院的学生将作为正式成员积极参与这项研究工作。＊＊＊

9623681 Feller This project will involve at least fifteen Coe College undergraduates in a number of projects in glass science. The purpose of the research is to find relationships between the atomic-level structure of important glasses, some never described before and some of commercial interest, and the physical properties exhibited by these glasses. The short-range atomic structure will be determined using various techniques, including magnetic resonance, optical spectroscopy, and neutron scattering. The physical properties to be related to the atomic arrangements include density, optical transmission, softening temperature, and glass-forming limits. An important aspect of this research, which will benefit and provide additional research training for the undergraduate students concerned, is the experience they will gain in working as part of an ongoing and large international collaboration established to study these glasses. %%% This research will involve the determination of quantitative structureproperty relationships in a wide variety of basic, novel, and commercially interesting glass systems. The glass families to be studied include alkali borates, alkali silicates, alkali borosilicates, alkali germanates, heavy metal oxide glasses based on lead and bismuth oxides, alkali vanadates, phosphates, chlorinated glasses and others. A number of complementary spectroscopic techniques including novel nuclear magnetic resonance, dynamic angle spinning, nuclear quadrupole resonance, elastic and inelastic neutron scattering at the Rutherford-Appleton lab, infra-red, and Raman scattering will be used. The physical properties to be examined include: density, glass transition temperature, optical characterization, and glassformation limits. The work is part of well-established world-wide collaborations. Another crucial aspect of the project is the heavy reliance on unde rgraduates; at least fifteen students from Coe College will be active as full members of this research effort. ***
