  Computer simulations of bi-continuous two-phase fluids with intersparsed
dumbbells show that, unlike rigid colloids, soft dumbbells do not lead to
arrested coarsening. However, they significantly alter the curvature dynamics
of the fluid-fluid interface, whose probability density distributions are shown
to exhibit (i) a universal spontaneous transition from an initial broad-shape
distribution towards a highly localized one and (ii) super-diffusive dynamics
with long-range effects. Both features may prove useful for the design of novel
families of soft porous materials.
