Indirect and direct 29Si dynamic nuclear polarization of dispersed nanoparticles

Author affiliations

Abstract

We show how the 29Si NMR signals of dispersed inorganic nanoparticles of laponite® can be enhanced by Dynamic Nuclear Polarization (DNP). The direct DNP enhances the signals of 29Si nuclei near unpaired electrons, whereas the indirect DNP via1H enhances the signals of more remote sites.
