The most intriguing feature is the ring formation that has been observed experimentally for sus- pensions of very different particle sizes ranging from nanometers [32, 36, 46, 47] to hundreds of micrometers. Pinning of the contact line and thermal Marangoni effects are often mentioned as necessary conditions for the ring formation. The contact line pinning is often assumed to result from substrate heterogeneities. Film height and concentration profiles at various instants during the dewetting process are displayed in Fig. 7. The profiles are from before, at and after self-pinning of the contact line. In Fig. 8 we display a space-time plot for the complete process. At first, the front recedes in the same manner as when there is no evaporation, but now driven by convection and evaporation. A small capillary rim forms that collects all the dewetted liquid that does not evaporate. The particle concentration slowly increases at the contact line (Fig. 7(a) and regime 21 dewetted liquid. The front recedes until all liquid is collected in a central drop. Since no liquid evaporates [ Q$_{nc}$ = 0 in Eq. (1)], the particle concentration does not change during the process. The situation changes when allowing for evaporation ( Q$_{nc}$ > 0 ). Now the front may retract by convection and/or evaporation. Evaporation leads to the possibility of a strong increase in the particle concentration at the contact line as evaporation is strongest there. Due to the strong nonlinear dependence of the viscosity on the particle concentration, this may lead to a dramatic decrease of the convective contribution to the front velocity. For moderate evaporation rates, this may result in a (temporary) self-pinning of the front. Within the present basic model, the process can (after complete dry-in) result in three different basic deposition patterns: (i) for very fast evaporation rates, all other processes occur over time scales that are much larger. In particular, the effects of convective redistribution of the liquid are neglectable. As a result one finds that a nearly homogeneous film of nanoparticles of thickness h$_{p}$ = φ$_{0}$h$_{0}$ is deposited (see Fig. 6(a)). Convection only results in the small heap of material visible at the left hand side of Fig. 6(a). The decrease in h$_{p}$ on the right side of Fig. 6(a) arises due to the diffusion of particles to the right of the initial front position; (ii) for very low evaporation rates, the film dynamics is dominated by convective dewetting as this process acts on a much shorter time scale than evaporation. As a result, all the liquid is collected into a drop before evaporation slowly removes the remaining solvent. Under these conditions most of the nanoparticles are deposited in a single heap (see Fig. 6(c)). Depending on the diffusivity, the heap might be highest at the centre or show a depression there; (iii) at intermediate evaporation rates, one may observe the deposition of a nanoparticle ring around a region with a nanoparticle film of much lower height. At the centre deposition might increase again (see Fig. 6(b)).
