Polarization is transferred from the protons of the solvent to the rare nuclei (here carbon-13 at natural isotopic abundance) at the surface, yielding at least a 50-fold signal enhancement for surface species covalently incorporated into a silica framework.Solid-State NmrMesoporous SilicaAcid GroupsChemistryExchangeRoutetext::journal::journal article::research article
