We present a simple, efficient method to fabricate superhydrophilic and underwater superoleophobic stainless steel mesh surfaces for robust oil–water separation.
Water scarcity is a serious global challenge, especially in arid and desert regions. Functional devices for directional water transport fog collection have received increasing attention. Existing methods technologies suffer from low fog-collecting efficiencies, complicated fabrication processes, high costs. Herein, we report simple low-cost method to rapidly fabricate nanoparticle-covered microstructures on one side of copper foam surface, using one-step femtosecond laser direct writing...
Massive discharging of oily wastewater has a serious impact on the ecological environment and human health. However, rapid development an efficient separation membrane exhibiting anti-fouling long-term stability for highly emulsified remains challenge. Herein, superwettable porous Ti foam was fabricated via facile ultrafast strategy femtosecond laser direct writing. The obtained surface possessed numerous nanoparticle-covered nanoripple structures with intriguing superhydrophilicity...
We report a simple, efficient method to fabricate micro/nanoscale hierarchical structures on one side of polytetrafluoroethylene mesh surfaces, using one-step femtosecond laser direct writing technology. The laser-treated surface exhibits superhydrophobicity in air and superaerophilicity water, resulting the possessing hydrophobic/superhydrophobic asymmetrical property. Bubbles can pass through from untreated but cannot opposite direction. therefore be designed for directional transportation...
In this paper, we present a rapid and simple method to fabricate superaerophilic polytetrafluoroethylene cones via two-step femtosecond laser direct writing technique, which enormously improved processing efficiency compared the existing method. The laser-treated contained hierarchical microstructures exhibited self-driven directional transport of gas bubbles along away from tip, even when were horizontal. Furthermore, excellent chemical long-term stability. This work may provide an...
In this letter, we report a Janus foam that is fabricated by the femtosecond laser structuring of copper foam. Each side possesses different wettabilities: one superhydrophilic while other hydrophobic. On foam, water can spontaneously antigravity transport from lower hydrophobic to upper without an input external energy, but cannot pass through in opposite direction. The be considered have “water diode” characteristics, and it enables continuous requiring any forces. then used design pump”....
We report a simple, efficient method to prepare Ti foam-based evaporator for solar evaporation and desalination.
Abstract In this study, a facile method is presented to fabricate superamphiphobic surfaces with controllable adhesion on polytetrafluoroethylene (PTFE), for the first time, using femtosecond laser Bessel beam. Compared previous structures mostly based 1D microstructure produced by Gaussian beam, are characterized highly uniform 2D periodic hill‐groove covered extensive porous‐mesh nanostructures. Most significantly, have very high‐aspect‐ratio since energy distribution of beam more over...
Solar desalination and fog harvesting are two common ways to obtain fresh water, both promising methods solve the water shortage problem. However, through either fabrication of interfacial evaporators for solar or preparation superwetting surfaces harvesting, current suffer from long times, high costs, low efficiency. Herein, we report an efficient simple method process heterogeneous (HSs) on aluminum (Al) by picosecond laser processing combined with chemical treatment used seawater...
We propose a high temperature-sensitive long period fiber grating (LPFG) sensor fabricated by using the femtosecond laser transversal-scanning method. The pulses scan over whole core and some part of cladding region; modified regions are more extended. It is found that LPFG-I method shows higher temperature sensitivity better uniformity than LPFG-II written point-by-point with 75.96 pm/°C in range 25°C–400°C measured. Moreover, from 400°C to 800°C, 148.64 good linearity 0.99 achieved, while...
