Building on recent advances in low temperature DNP
methods for producing hyperpolarized (HP) Xe-129 for MRI
applications, we explore DNP efficiency of homogeneously
mixed Xe/1-propanol/trityl radical mixtures in the
solid-state using a newly developed apparatus and
evaluate the utility of NMR observables as probes of
sample heterogeneity.
