RUI: Comprehensive Spectroscopic and Property Studies of Borate and Borosilicate Glasses Including Unusual High Cesium and Rubidium Content Materials

这个RUI在一系列具有基础和技术重要性的玻璃中处理结构-性质关系。主要的测量技术是核磁共振，它提供了关于各种玻璃中原子的成键和局部环境的信息。后者包括碱性硼硅酸盐，特别是高碱含量玻璃。研究结果与玻璃在不同加工条件下的稳定性有关。这一信息在眼镜技术生产的背景下是有意义的。另一个子项目解决了材料中的玻璃过渡问题。玻璃化转变的性质及其结构基础仍然是凝聚态科学中一个具有挑战性的问题。%%%

This RUI addresses structure-property relations in a range of glasses which have both fundamental and technical importance. The primary measurement technique is nuclear magnetic resonance, which provides information about the bonding and local environment of the atoms in the various glasses. The latter include alkali borosilicates, particularly high alkali content glasses. The results bear on the glass stability under different processing conditions. This information is of interest in the context of technical production of glasses. A further sub-project addresses the glass transition in the materials. The nature of the glass transition and its structural basis remains a challenging problem in condensed matter science. %%%
