A large sample volume magic angle spinning nuclear magnetic resonance probe for in situ investigations with constant flow of reactants

February 13, 2012 - This post is not particular about DNP. However, it is a very interesting piece of instrumentation that demonstrates the state-of-the-art of instrumentation for MAS-NMR.

Dynamic nuclear polarization at 9T using a novel 250 Gyrotron microwave source

January 6, 2012 - Griffin, R. G. J. Magn. Reson. 2011, 213, 410 http://dx.doi.org/10.1016/j.jmr.2011.08.015 In the 1990’s we initiated development of high frequency gyrotron microwave sources with the goal of performing dynamic nuclear polarization at magnetic fields (~5-23T) used in contemporary NMR experiments.
