      abstract     = {Pure and filled epoxies are widely used in industry.
                      Nanocomposites especially are affected by interphase regions
                      where properties deviate from bulk. The study of molecular
                      mobility in epoxy monomers is a first step to understanding
                      the molecular dynamics in nanocomposites and their effect on
                      crosslinking in epoxy networks. Here, quasi‐elastic
                      neutron scattering is used to disentangle the molecular
                      motions of monomeric diglycidylether of Bisphenol A (DGEBA)
                      and a suspension of zeolite nanoparticles in DGEBA on a
                      timescale from 2 ps to 5.5 ns. Regarding molecular transport
                      of DGEBA inside the suspension, the particles have no impact
                      on the faster rotational motions. A combination of neutron
                      time‐of‐flight and backscattering spectroscopy reveals a
                      pronounced hindrance of DGEBA molecular dynamics on/in the
                      zeolite particles along with a new type of molecular motion
                      occurring on intermediate timescales. That localized motion
                      is attributed to jump diffusion motions, emanating from
                      interphase effects at the zeolite particles.},
