All simulations were run using the dl meso simulation package (version 2.8), at a reduced temperature of T = 1.0 (which is equivalent to 25 ℃ according to the underlying parameterization). A time step of 0.02 (DPD units) was used through out. For NPT simulations a Langevin-piston barostat was used, with p = 23.7 in reduced units to correspond to the pressure in our bead model of pure water at a reduced density ρr 3 c = 3.
