  • A fundamental limitation for the practical use of dynamic nuclear polarization using photo-excited triplet state - the need of strictly oriented single crystal - is overcome in this work through the development of fullerene-based polarizing agents.

  • Singlet fission (SF) can create spin-polarized quintet states in organic systems, but this effect and its potential applications have not been sufficiently explored. Here, authors demonstrate that SF in supramolecular assemblies of pentacene chromophores improves the sensitivity of magnetic resonance of water molecules through dynamic nuclear polarization in a water-glycerol glass.

  • In quantum chromodynamics, the condensation of quark–antiquark pairs breaks the chiral symmetry of vacuum. Experiments with pionic tin atoms demonstrate that the symmetry is partially restored at high densities.
