Femtosecond-laser-patterned origami Janus membrane toward enhanced water fog harvesting

Abstract

Fog harvesting is an effective way to relieve water shortages in arid regions; thus, improving the efficiency of fog harvesting is an urgent need for both academic research and practical...

Designing Janus Two-Dimensional Porous Materials for Unidirectional Transport: Principles, Applications, and Challenges

“…(c) Janus structure inspired by eaves for fog harvesting. Reproduced with permission from ref . Copyright 2023, Royal Society Chemistry.…”

“…The water collection rate can be further enhanced by the structure design. Inspired by traditional Chinese architectural roof tiles with excellent water collection and drain capacity (Figure c), Yao et al developed a corrugated cardboard-shaped Janus membrane patterned by femtosecond laser ablation, which performed at an approximately 267% water collection rate compared to the planar ones …”

Recent advances in functional micro/nanomaterials for removal of crude oil via thermal effects

“…Recently, new adsorbents with hydrophobicity and oleophilic properties have been favoured over other treatment methods because they meet the above conditions. 38–41 Adsorbents are applied easily, are reusable, low cost and non-toxic to marine life and the environment. 42–45 However, due to the fact that 40% of the world's oil reserve is heavy crude oil, its high viscosity (10 3 to 10 5 mPa s at room temperature) strongly inhibits crude oil adsorption that relies on van der Waals forces and capillary action.…”
