Dewetting current
WebUsually, electrowetting on superhydrophobic surfaces (EWOSS) is generated by application of an alternating current signal and often leads to droplet impalement into the structuration. To avoid this phenomenon, superhydrophobic surfaces must show robustness to … In fluid mechanics, dewetting is one of the processes that can occur at a solid–liquid, solid–solid or liquid–liquid interface. Generally, dewetting describes the process of retraction of a fluid from a non-wettable surface it was forced to cover. The opposite process—spreading of a liquid on a substrate—is called wetting. The factor determining the spontaneous spreading and dewetting for …

Hence, the current approach to reversibly control the spinodal dewetting of thin liquid films underneath aqueous drops with an external electric field can be ...
Webthat in nanopores wetted by RTILs a gradual dewetting transition occurs upon increasing the applied voltage, which is accompanied by a sharp increase in ionic current. These … WebMar 17, 2024 · Eq. 1 underlies an elementary description of delamination as a generalization of the standard dewetting transition (which occurs as Γ → 0 + ), to “curvature-induced dewetting” (which occurs as Γ* → 0 + ). In this generalization, the sheet’s elastic energy is simply viewed as an addition to the sheet–substrate adhesion energy.
WebAug 1, 2024 · In this opinion, we will review recent work focusing on potential-induced and multiple stimuli-induced switchable wetting and dewetting in hydrophobic nanochannels. … WebIn addition, reversible dewetting of the hydrophobic region of the pore was observed as voltage-dependent ion current fluctuations in time between conducting and non-conducting states. The observations are in accordance with earlier molecular dynamics simulations, which predicted the possibility of spontaneous and reversible dewetting of ...
WebJul 30, 2024 · We show that the solid-state dewetting technique developed [6; 11; 16; 21] allows the fabrication of ultra-pure, homogeneous, highly dense Si NCs with tunable size at nanometer scale which gives an effective control of their bandgap energy (via the energy quantification of carriers) and of their optical and electronic properties [ 11 ].
