A mechanochemical "solvent-free'' route is presented for the preparation of solid samples ready to be employed in the Dynamic Nuclear Polarization (DNP). H-1-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).

Abstract
A mechanochemical "solvent-free'' route is presented for the preparation of solid samples ready to be employed in the Dynamic Nuclear Polarization (DNP). H-1-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).File in questo prodotto:
