Angewandte Chemie, EarlyView.High‐resolution proton detection is preserved under cryogenic dynamic nuclear polarization (DNP) by combining fast MAS, extensive deuteration and selective methyl protonation. This strategy enables proton‐detected structural studies of biomolecular solids with enhanced sensitivity under DNP conditions.

Proton‐Induced Perthionitrite‐Mediated Zinc Thiolate Persulfidation
Angewandte Chemie, EarlyView.A thiolate‐supported zinc thionitrite complex reacts with S8 to insert sulfur at both Zn–S bonds. Although SNO− persulfidation to SSNO− is facile, thiolate persulfidation is less favored in comparison. These thermodynamic differences between S–S‐containing moieties are also observed for free perthiolate and SSNO− anions.

Skyrmion Bubbles by Design in a Centrosymmetric Kagome Magnet
Advanced Science, EarlyView.Chemical tuning of magnetocrystalline anisotropy in the centrosymmetric kagome magnet TmMn6Sn6 is shown to drive a spin reorientation transition via an intermediate magnetic fan state and to stabilize an emergent skyrmion bubble lattice. Four‐dimensional cryogenic Lorentz scanning transmission electron microscopy confirms the nanoscale texture ...
