Dissolution dynamic nuclear polarization efficiency enhanced by Hartmann-Hahn cross polarization

► Combination of DNP, cross polarization, and dissolution in a dissolution DNP probe. ► A multi-sample dissolution DNP probe was modified and used. ► Improved cross-polarization efficiency using adiabatic half-passage pulses. ► DNP enhancement after dissolution by a factor of two. ► Speed up of polarization build up by a factor of two.
