In a study led by Alexander Pines, a senior faculty scientist with Berkeley Lab's Materials Sciences Division and UC Berkeley's Glenn T. Seaborg Professor of Chemistry, researchers recorded the first bulk room - temperature NMR hyperpolarization of carbon - 13 nuclei in diamond in situ at arbitrary magnetic fields and crystal orientations.

«Our results in this study represent an NMR signal enhancement equivalent to that achieved in the pioneering experiments of Lucio Frydman and coworkers at the Weizmann Institute of Science, but using microwave - induced dynamic nuclear hyperpolarization in diamonds without the need for precise control over magnetic field and crystal alignment,» Pines says.

The authors believe this new hyperpolarization technique should enable orders of magnitude sensitivity enhancement for NMR studies of solids and liquids under ambient conditions. (sciencedaily.com)
