Airflow Enhanced Solar Evaporation Based on Janus Graphene Membranes with Stable Interfacial Floatability.

Solar interfacial evaporation has been recognized as a versatile energy conversion protocol for cutting-edge applications such as water treatment and power generation (e.g., hydro voltaic effect).

Kraft Mesh Origami for Efficient Oil-Water Separation.

Inspired from fish scales that exhibit unique underwater superoleophobicity, artificial porous membranes featuring similar wettability have been successfully developed for oil-water separation. However, most of the superoleophobic meshes are workable only for underwater oil/water separation and become disabled in air. In this article, we reported the facile fabrication of underwater superoleophobic kraft mesh and demonstrated efficient oil-water separation using kraft mesh origamis.

Directly drawing high-performance capacitive sensors on copying tissues.

We report here a facile, green and cost-effective fabrication of high-performance capacitive pressure sensors by drawing loop-and disc-shaped graphite electrode arrays on copying tissues. Graphene oxide enhanced foam-like paper is prepared as an efficient dielectric layer. The paper-based capacitive pressure sensor enables sensitive detection of finger touch, motion and proximity.

Laser-structured Janus wire mesh for efficient oil-water separation.

We report here the fabrication of a Janus wire mesh by a combined process of laser structuring and fluorosilane/graphene oxide (GO) modification of the two sides of the mesh, respectively, toward its applications in efficient oil/water separation. Femtosecond laser processing has been employed to make different laser-induced periodic surface structures (LIPSS) on each side of the mesh. Surface modification with fluorosilane on one side and GO on the other side endows the two sides of the Janus mesh with distinct wettability.
