New paper from the group
We describe a new sample formulation for MAS DNP, showing that good sensitivity enhancements be obtained in water without glycerol (or other glass forming agents) simply by dissolving
high concentrations of electrolytes (such as NaCl or LiCl), which perturb the otherwise
unavoidable ice crystallization observed upon cooling, thereby reducing PA phase separation
and restoring DNP efficiency.
