Wetting morphologies on randomly oriented fibers.
We characterize the different morphologies adopted by a drop of liquid placed on two randomly oriented fibers, which is a first step toward understanding the wetting of fibrous networks. The present work reviews previous modeling for parallel and touching crossed fibers and extends it to an arbitrary orientation of the fibers characterized by the tilting angle and the minimum spacing distance. ...
متن کاملWetting morphologies at microstructured surfaces - Supp
In order to construct topographically microstructured surfaces with a certain wettability, we used the following procedures. Using standard photolithographic methods with pulsed ion gas etching, silicon substrates were topographically structured with surface grooves of rectangular cross–section, see Figure S1. More precisely, five different samples were fabricated, each of which contained four ...
متن کاملWetting morphologies on an array of fibers of different radii.
We investigate the equilibrium morphology of a finite volume of liquid placed on two parallel rigid fibers of different radii. As observed for identical radii fibers, the liquid is either in a column morphology or adopts a drop shape depending on the inter-fiber distance. However the cross-sectional area and the critical inter-fiber distance at which the transition occurs are both modified by t...
متن کاملA Nano-scale Fabry-perot Interferometer Using Channel Plasmon-polaritons in Triangular Metallic Grooves
In this letter, we demonstrate the possibility of an effective nano-scale FabryPerot interferometer in a sub-wavelength plasmonic waveguide in the form of a triangular groove on a metal surface, guiding channel plasmon-polaritons (CPPs). The resonant cavity is formed by two semitransparent metal membranes (mirrors) placed into the groove. Effective filtering effect of the cavity is demonstrated...
متن کاملBubble Meets Droplet: Particle-Assisted Reconfiguration of Wetting Morphologies in Colloidal Multiphase Systems.
Wetting phenomena are ubiquitous in nature and play key functions in various industrial processes and products. When a gas bubble encounters an oil droplet in an aqueous medium, it can experience either partial wetting or complete engulfment by the oil. Each of these morphologies can have practical benefits, and controlling the morphology is desirable for applications ranging from particle synt...
