Solid State NMR: A Powerful Tool for the Characterization of Borophosphate Glasses

Autor: Grégory Tricot, Lazzat Alpysbay, Bertrand Doumert

Publikováno v: Molecules, Vol 25, Iss 2, p 428 (2020)

This review will show how solid state nuclear magnetic resonance (NMR) has contributed to a better understanding of the borophosphate glass structure. Over the last fifteen years, 1D and 2D magic angle spinning (MAS)-NMR has been used to produce key
