From: Evaporation and deposition of inclined colloidal droplets
Ring width growth during evaporation. (a) The top-view image of the final deposit for \(\phi = 90^{\circ}\), \(D = 50\) nm, and \(H = 0.5\) after evaporation. (b) The top (bottom) ring width growth, \(d_{top}\) (\(d_{bottom}\)) normalized by the droplet contact radius R, with the evaporation time, \(t/t_f\) (\(t_f\) is the complete evaporation time). (c) and (d) The up-close sequential images at the top and the bottom rings, respectively.
