DNP is combined with cross-polarization and MQ-MAS to determine local symmetries of Al-27 sites at the surface.Angle-Spinning NmrQuantum Mas NmrMultiple-QuantumGamma-AluminaHeterogeneous CatalystsOlefin MetathesisExchange-ReactionOxide CatalystsHydroxyl-GroupsSilica-AluminaDynamic nuclear polarization of quadrupolar nuclei using cross polarization from protons: surface-enhanced aluminium-27 NMRtext::journal::journal article::research article
