摘要: Aqueous acrylamide gels can be used to provide dynamic nuclear polarization (DNP) NMR signal enhancements of around 200 at 9.4 T and 100 K. The are shown increase with crosslinker concentration low concentrations the AMUPol biradical. This DNP matrix in situations where conventional incipient wetness methods fail, such as obtain surface enhanced spectra from inorganic nanoparticles. In particular, we Cd-113 CdTe-COOH NPs minutes. clearly indicate a highly disordered cadmium-rich surface.
