A proposed mechanism of the combined structure formation. a Ag particles in toluene; b movement of contact line and the development of a sinusoidal interface where particles
are captured; c droplet formation; d droplets shrinking (not to scale); e Outward flow and deepening of particles toward the substrate; f spot formation due to the deposition of the particles on the substrate and ring formation
due the outward compensation
