Efficient Hyperpolarization of U- 13C-Glucose Using Narrow-Line UV-Generated Labile Free Radicals #DNPNMR

January 14, 2019 - DNP requires a paramagnetic polarizing agent. This is great for DNP but not so great for the NMR experiment, since the paramagnetic species often causes line broadening due to increase nuclear relaxation.

Persistent Radicals of Self-assembled Benzophenone bis-Urea Macrocycles: Characterization and Application as a Polarizing Agent for Solid-state DNP MAS Spectroscopy #DNPNMR #NMR

February 12, 2018 - Most commonly nitroxide-based radicals are used in DNP. However, there are many other stable radicals. This one is a UV generated radical that is stable for weeks at room temperature.
