Outside Front Cover: Preserving Proton Resolution Under Cryogenic Dynamic Nuclear Polarization for Biomolecular Solid‐State NMR

Dynamic nuclear polarization (DNP) combined with fast magic-angle spinning brings high sensitivity and resolution to proton-detected NMR of biomolecular solids under cryogenic conditions. The cover illustrates this approach using HET-s amyloid fibrils, with microwave-driven polarization enhancement illuminating selectively labelled methyl groups and enabling resolved 1H-13C correlations and atomic-scale structural information.
