title: Dynamic nuclear polarization of a glassy matrix prepared by solid state mechanochemical amorphization of crystalline substances.
abstract: A mechanochemical "solvent-free" route is presented for the preparation of solid samples ready to be employed in the Dynamic Nuclear Polarization (DNP). (1)H-DNP build-up curves at 3.46 T as a function of temperature and radical concentration show steady state nuclear polarization of 10% (0.5% TEMPO concentration at 1.75 K).
