Title: Growing Signals from the Noise: Challenging Nuclei in Materials DNP

Abstract

Here, the polarization of nuclear spins by dynamic nuclear polarization (DNP) has redefined the sensitivity limits of solid–state (SS) NMR spectroscopy. Materials science has been arguably one of the key beneficiaries of the recent remarkable advances of the technique, which included low–temperature magic angle spinning (MAS), modern gyrotrons, and biradical agents for polarization transfer via the cross–effect. In many classes of materials, DNP offers the capability of selectively sensitizing progressively smaller surface and interfacial regions of materials and eliciting responses from previously undetectable nuclei, with no detrimental effect on resolution. We review the most recent applications of DNP–enhanced SSNMR to materials, focusing specifically on measurements that pose insurmountable challenges to conventional SSNMR, including the detection of 15N, 17O, 25Mg, 35Cl, 43Ca, 79Br, 89Y, 119Sn, and 195Pt by one–dimensional MAS methods, ultrawideline NMR, as well as two–dimensional homo– and heteronuclear correlation spectroscopy.
