title: Under-water unidirectional air penetration via a Janus mesh.
abstract: Under-water and unidirectional air penetration, viz. air "diode", was effectively achieved on the basis of a composite mesh with Janus wettability. In the aqueous solution, the air bubbles can only pass through the mesh from the hydrophilic side to the superhydrophobic side, whereas they will be blocked from the opposite direction.
