 Current opportunity for research impact lies mainly in fundamental research and practical manufacturing.Debates have recently emerged concerning the applicability of the Wenzel and Cassie-Baxter models.In an experiment designed to challenge the surface energy perspective of the Wenzel and Cassie-Baxter model and promote a contact line perspective, water drops were placed on a smooth hydrophobic spot in a rough hydrophobic field, a rough hydrophobic spot in a smooth hydrophobic field, and a hydrophilic spot in a hydrophobic field.
