    <p><b>A1</b>. Advancing angle of drop on surface showing Cassie-Baxter wetting. <b>A2</b>. Receding angle of drop showing Cassie-Baxter wetting. <b>A3</b>. Ease of drop removal on a surface showing Cassie-Baxter wetting. <b>B1</b>. Advancing angle of drop on surface showing Partial Cassie-Baxter wetting. <b>B2</b>. Receding angle of drop showing Partial Cassie-Baxter wetting. <b>B3</b>. Drop removal on a surface showing Partial Cassie-Baxter wetting, showing that while initial removal is similar to perfect Cassie-Baxter wetting, a localized point remains. <b>C1</b>. Advancing angle of drop on surface showing Wenzel wetting. <b>C2</b>. Receding angle of drop showing Wenzel wetting. <b>C3</b>. Attempted drop removal on a surface showing Wenzel wetting.</p
