September 28, 2018 - This is not directly related to DNP spectroscopy but an interesting method to increase the sensitivity specifically in solid-state NMR experiments.
August 8, 2016 - Not an article that directly relates to DNP-NMR spectroscopy, but another interesting technique to enhance sensitivity that can be combined with DNP.
