Surfaces which possess extraordinary water attraction or repellency depend on surface energy, chemistry, and nano- microscale roughness. Synergistic superhydrophilic-underwater superoleophobic surfaces were fabricated by spray deposition of nanostructured TiO2 stainless steel mesh substrates. The coated meshes then used to study gravity driven oil-water separation, where only the from mixture is allowed permeate through mesh. Oil-water separation efficiencies up 99% could be achieved pore...
Abstract Photoresponsive titania surfaces are of great interest due to their unique wettability change upon ultraviolet light illumination. However, applications often limited either by the inability respond visible or need for special treatment recover original wettability. Sensitizing TiO 2 with light-absorbing materials has been utilized in photovoltaic applications. Here we demonstrate that a dye-sensitized surface can selectively towards contacting liquids illumination photo-induced...
New measurements and a reference correlation for the surface tension of seawater at atmospheric pressure are presented in this paper. Surface was measured across salinity range 20 ⩽ S 131 g/kg temperature 1 t 92 °C using Wilhelmy plate method. The uncertainty within varied from 0.18 to 0.37 mN/m with average being 0.22 mN/m. experimental procedures were validated tests conducted on ACS reagent grade water aqueous sodium chloride solutions. Literature data present evaluated developed...
Superhydrophobic surfaces submerged under water appear shiny due to total internal reflection of light from a thin layer air (plastron) trapped in their surface texture. This entrapped is advantageous for frictional drag reduction various applications ranging microfluidic channels marine vessels. However, these aerophilic textures are prone impregnation by turbulent pressure fluctuations external flows and dissolution the gas into water. We demonstrate novel chemical method replenish...
Fizzy water drops levitate and slide freely when placed on a superhydrophobic solid at ambient temperature.
Abstract Titanium dioxide (titania or TiO 2 ) is well known for its photocatalytic properties and ability to remove organic contaminants under UV light illumination. It also switch surface wetting characteristics from being hydrophilic superhydrophilic exposure in air. However, less about the switching of hydrophilicity surfaces immersed an oil medium. In this work, self‐assembled nanoparticle are environment, kinetics contamination‐induced hydrophobicity photoinduced studied using situ...

We present a facile method for fabrication of Titania (TiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ) based superhydrophobic surfaces by silanization with wettability switching from to superhydrophilic under ultraviolet (UV) light irradiation. The dynamic surface UV irradiation was tested ambient environment as well in oily environment. synthesized TiO contact angle high 154º advancing and 152ºfor receding air. A dramatic decrease...
