A droplet of water forms a bead on the surface of a lotus left, top left, while a drop of hexadecane soaks the surface, top right. After the lotus leaf is coated with a new oil-repelling material developed at MIT, water still beads up, bottom left, and so does hexadecane, bottom right. Inset photo in the top left square shows an SEM micrograph of the lotus leaf surface. Image courtesy / Anish Tuteja and Wonjae Choi, MIT |
