Effect of particle geometry on triple line motion of nano-fluid drops and deposit nano-structuring

(a) Nano-structuring of graphene deposit (0.1 wt.%). (b) 3D representation of the same area. (c) Effect of particle geometry on the excess free energy per unit length,δG¯, accumulated in each system at the moment of the first jump. δG¯ was normalised by surface tension of water, 0.073 N/m, for the aqueous solutions (square and circle symbols) and that of ethanol, 0.024 N/m, for the rest.
