Solid-State Dynamic Nuclear Polarization at 9.4 and 18.8 T from 100 K to Room Temperature
From The DNP-NMR Blog:
Solid-State Dynamic Nuclear Polarization at 9.4 and 18.8 T from 100 K to Room Temperature
This is an incredible article. It shows the temperature dependence of the DNP enhancement over a wide temperature regime. Most importantly it shows that at room temperature still an enhancement of 15-20 can be achieved.
Just a few years ago the common believe was that solid-state MAS-DNP experiments have to be performed at 90 K or below. This article clearly demonstrates that there is still so much room for improvements of DNP. I think the most exciting moments in DNP are...

Room temperature hyperpolarization of nuclear spins in bulk
Tateishi, K., et al., Room temperature hyperpolarization of nuclear spins in bulk. Proc. Nat. Aca. Sci. USA, 2014. 111(21): p. 7527-7530.
http://www.pnas.org/content/111/21/7527.abstract
Dynamic nuclear polarization (DNP), a means of transferring spin polarization from electrons to nuclei, can enhance the nuclear spin polarization (hence the NMR sensitivity) in bulk materials at most 660 times for 1H spins, using electron spins in thermal equilibrium as polarizing agents. By using electron spins...
