Neutron scattering provides space/time resolution at the relevant length scales in soft matter. The selectivity provided by the combination of this technique with isotopic-in particular, proton/deuterium-labeling allows the isolated study of chosen molecular groups and/ or components in a system. Both features make neutron scattering a unique tool for unraveling the nature of the large variety of molecular motions taking place in polymeric materials of increasing complexity. As presented by Juan Colmenero and Arantxa Arbe on page 87, the cover illustrates in an artistic way the process of neutron scattering by a macromolecule. The different colors of the “scattered neutrons” represent different energy transfers in quasielastic events.
