Specifically, we constructed superhydrophilic vein-like microchannels on a superhydrophobic brass surface by using laser texture technology and hydrothermal treatment. Our microchannel design acts as a "highway" for synergically transporting and converging the collected fog droplets, as well as rapidly ...
As a century-old concept, superwettability has aroused the interest of researchers in the past decades, attributed to the discoveries of the mechanisms of special wetting phenomena in nature. Bio-inspired manufacturing of superwetting surfaces for fog collection and anti-icing applications has become ma...
During this process, the gradient of the Laplace pressure between the two sides causes the water drops on the barbs to continuously move towards the base of the barbs. Figure 3: In situ optical microscopic observation of the detailed water collection process on a single horizontal spine and two...
As the vortex-assisted fog collection mechanism addresses the aerodynamic deviation limitation at lowStk8, it alleviates the dependence of fog capture on the wind speed. As plotted in Fig.2f, the growth rate of droplets on cubickirigamiwithθof 150° is improved steadily from 5.42 × 10...
This study describes the development of a fog collector material for fog harvesting. Polypropylene (PP) doped with fumed silica (0–2%) was punctured at equal intervals and exposed to fog produced by a humidifier. The amount of water harvested by each sa
In this work, we explore a fog harvesting flexible hybrid surface that has a superhydrophilic 3D copper oxide pattern on a hydrophobic rough elastomer background surface enabled by transferring a copper layer from a prepared donor substrate to a receiving elastomer substrate. The water collection ...
