Published: February 2017

Surface-selective direct O DNP has been demonstrated for the first time on CeO nanoparticles, for which the first three layers can be distinguished with high selectivity. Polarisation build-up curves show that the polarisation of the (sub-)surface sites builds up faster than the bulk, accounting for the remarkable surface selectivity.
