1. A transition included angle based method of predicting and controlling the wetting of a solid by a liquid comprising the
steps of:
providing a solid having a surface geometry,
providing a liquid,
placing the liquid in contact with the solid,
measuring a transitional included angle formed between the solid and the liquid; and
specifying the surface geometry of the solid at least in part based upon the transitional included angle to achieve a desired
degree of wetting of the solid by the liquid.
