Wettability Engineering: Wettability Engineering for Studying Ion Transport in 2D Layered Materials (Adv. Mater. Interfaces 3/2021)

Wettability engineering is exploited to tame an electrolyte drop and place it accurately along the perimeter of a bilayer of graphene in order to generate a peripheral galvanic cell. This is accomplished by patterning a material (red) on top of the substrate with a large contact angle difference with respect to the substrate itself.
