Surface-selective direct 17O DNP NMR of CeO2 nanoparticlesTools Hope, Michael A., Halat, David M., Magusin, Pieter C.M.M., Paul, Subhradip, 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.
