A quasi-optical and corrugated waveguide microwave transmission system for simultaneous dynamic nuclear polarization NMR on two separate 14.1 T spectrometers #DNPNMR

February 21, 2018 - Gyrotrons typically generate much more microwave power than needed in a DNP-NMR experiment. This article describes a very nice way how to share the microwave power generated by a single gyrotron between two NMR experiments.

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.
