Improved Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy through Controlled Incorporation of Deuterated Functional Groups

David Lyndon Emsley, Aaron James Rossini, Moreno Lelli

In a spin: The use of deuterated surface passivation agents is shown to restore dynamic nuclear polarization (DNP) surface-enhanced NMR signals that are reduced in substrates containing methyl groups, while still protecting sensitive sites on the surface ( ...

Functional, Hyperbranched Polyesters Via Baylis-Hillman Polymerization

Harm-Anton Klok, Frederik Roman Wurm, Sanhao Ji

Hyperbranched polyesters are among the most common hyperbranched polymers. One of the interesting features of hyperbranched polyesters is that they contain unreacted hydroxyl and carboxylic acid groups at the linear and terminal structural units, which can ...
