title: Surface-selective direct17O DNP NMR of CeO2nanoparticles.
abstract: Surface-selective direct17O DNP has been demonstrated for the first time on CeO2nanoparticles, 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.
