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. %%%

该 RUI 解决了一系列具有基础和技术重要性的玻璃的结构-性能关系。 主要的测量技术是核磁共振，它提供有关各种玻璃中原子的键合和局部环境的信息。 后者包括碱金属硼硅酸盐，特别是高碱含量玻璃。 结果与不同加工条件下的玻璃稳定性有关。 该信息在眼镜技术生产的背景下很有趣。 另一个子项目解决了材料中的玻璃化转变。 玻璃化转变的性质及其结构基础仍然是凝聚态科学中的一个具有挑战性的问题。 %%%
