Surface-selective direct 17O DNP NMR of CeO2 nanoparticlesTools Hope, Michael A. and Halat, David M. and Magusin, Pieter C.M.M. and Paul, Subhradip and Peng, Luming and Grey, Clare P. (2017) Surface-selective direct 17O DNP NMR of CeO2 nanoparticles. Chemical Communications, 53 (13). pp. 2142-2145. ISSN 1364-548X Full text not available from this repository.AbstractSurface-selective direct 17O DNP has been demonstrated for the first time on CeO2 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.
