  In this work, we focus on different length scales within the dynamics of
nucleons in conditions according to the neutron star crust, with a
semiclassical molecular dynamics model, studying isospin symmetric matter at
subsaturation densities. While varying the temperature, we find that a
solid-liquid phase transition exists, that can be also characterized with a
morphology transition. For higher temperatures, above this phase transition, we
study the neutrino opacity, and find that in the liquid phase, the scattering
of low momenta neutrinos remain high, even though the morphology of the
structures differ significatively from those of the traditional nuclear pasta.
