Chem Commun (Camb), 2017. 53(13): p. 2142-2145. https://www.ncbi.nlm.nih.gov/pubmed/28134945 Surface-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. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica} p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica} Go to The DNP-NMR Blog for more info. |
