SEENG ORDER IN DISORDERED MATERIALS: THE VIEW FROM NMR SPECTROSCOPY
The term "disordered materials" obscures the fact that a great deal of order exists within many systems so named. Seen from the perspective of nuclear magnetic resonance (NMR) spectroscopy, glasses, for example, possess many levels of structural order. Decades of NMR research have established valuable relationships between structural elements in glasses and their bulk properties, revealing fundamental trends and guiding materials development. Continual advances in NMR technology and methodology are only strengthening its potency in this regard, making it uniquely suited for the study of such materials. In this presentation, I will use a variety of examples from my research group to illustrate how NMR is refining our understanding of structure and dynamics in borate-based glasses, and challenging traditional views of network-forming glasses.
