ABSTRACT
In recent years, the study of the effect of solid particles of micro/nanometric dimensions on the properties of liquid interfaces has undergone an intense development (Binks 2002; Pugh 1996). Under specific conditions, especially if interacting with surfactants, particles are in fact able to segregate at the interface and stabilize it, opposing droplet/bubble coalescence. This makes these systems particularly important for the stabilization of bubbles, liquid films, and disperse systems such as emulsions and foams (Aveyard et al. 2003; Binks et al. 2008; Grigoriev et al. 2007a;
