RUI: Nuclear Magnetic Resonance Studies of Glasses

点击翻译按钮获取中文摘要

This research program involves the study of glasses, primarily through the use of nuclear magnetic resonance. The proposed research is in several different areas. One area is a collaboration (S.W. Martin, Iowa State) on 29Si magic angle sample spinning NMR on alkali borosilicate glasses over an extremely wide range of compositions. A second area is an continuation of studies with P. Bray (Brown) on the 10B and 11B nuclear quadrupole resonance properties of alkali borate glasses. Further studies will also be made of extremely high alkali content alkali borate glasses with the emphasis on exploring the relationship between structure and physical properties. A new collaboration with Kamitsos (National Hellenic Research Foundation, Athens) on joint infrared and Raman spectroscopic studies of very high alkali contnet borate glasses will be initiated.
