Abstract
A semi-rigid trityl-nitroxide polarizing agent is introduced for magic angle spinning (MAS) dynamic nuclear polarization (DNP), which significantly broadened the scope of solid-state NMR to study biomolecular systems and materials.

Abstract
Solid-state DNP NMR is applied to detect a small amount of a minor polymorph of an organic material within a major polymorphic phase, yielding quantitative details of the spatial distribution of the two polymorphs within particles in a powder sample.

Abstract
The possibility of enriching in 17O the water molecules within hydrated biominerals belonging to the Ca-pyrophosphate family was investigated, using liquid assisted grinding (LAG) in the presence of 17O-labelled water.
