text: scopic ﬁlm. We have seen that the KMC model is able to describe the interplay of solute diffusion 
  
  within the solvent and solvent evaporation/condensation. It also takes the liquid-liquid, liquid- 
  
  particle and particle-particle interactions into account and therefore allows us to distinguish differ- 
  
  ent regimes of the transverse (ﬁngering) instability of the evaporative dewetting front: a transport 
  
  regime where the instability is almost completely independent of the interaction strengths and 
  
  a demixing regime where particles and liquid demix at the receding front thereby increasing its 
  
  transverse instability. 
  
  The dynamical density functional theory describes the coupled dynamics of the density ﬁelds of 
  
  the liquid and the nanoparticles. In the form described above (i.e. based on the two-dimensional 
  
  hamiltonian (3)) we obtain a simple theory that allows us to study the time evolution of the evapo- 
  
  rating ultrathin ﬁlm and also to investigate the inﬂuence of processes such as surface diffusion by 
  
  the liquid, which are not incorporated in the KMC model. However, it is straightforward to extend 
  
  the theory to consider a fully three-dimensional ﬂuid ﬁlm, in which one can distinguish between
