    • Recent work by McCarthy and colleagues (20) points out that these models are applicable only at the solid-liquidvapor three-phase contact line (drop perimeter) and that the interfacial area within the drop perimeter does not affect either the apparent contact angle or the hysteresis; thus, these models can be easily applied only to surfaces with a homogeneous texture, as considered here.

    • These surfaces are referred to as micro-hoodoos because their geometry and process of creation are reminiscent of geological features called hoodoos, which are created by soil erosion. Hoodoos are composed of a soft sedimentary rock topped by a piece of harder, less easily eroded stone

    • sl is the change in solid-liquid contact area with the advancing or receding of the liquid, and dθ is the change in local contact angle. This criterion also emphasizes the importance of re-entrant surfaces.
