Non-crystalline Earth materials under extreme compression: A view from solid-state NMR

Advances and recent progress in solid-state NMR combined with high pressure techniques, such as multi-anvil press have allowed us to reveal the previously unknown structural details of bonding transitions in non-crytstalline oxides (i.e., silicate melts and magmas and technologically important oxide glasses).
