DESCRIPTION:Low-density networks of molecules or colloids form at low temp
 eratures when the interparticle interactions are valence limited. Prototyp
 ical examples are networks of patchy particles\, where the limited valence
  results from highly directional pairwise interactions. We combine extensi
 ve Langevin simulations and Wertheim&rsquo\;s theory of association to stu
 dy these networks. We find a scale-free (relaxation) dynamics within the l
 iquid&ndash\;gas coexistence region\, which differs from that usually obse
 rved for isotropic particles. While for isotropic particles the relaxation
  dynamics is driven by surface tension (coarsening)\, in low-density netwo
 rks the slow relaxation proceeds through the formation of an intermediate 
 non-equilibrium gel via a geometrical percolation transition. We show that
  the low temperature slow dynamics is universal\, being observed also in t
 he single phase region.<br> <br> C. S. Dias\, J. M. Tavares\, N. A. M. Ara
