Leaping shampoo glides on a lubricating air layer.
When a stream of shampoo is fed onto a pool in one's hand, a jet can leap sideways or rebound from the liquid surface in an intriguing phenomenon known as the Kaye effect. Earlier studies have debated whether non-Newtonian effects are the underlying cause of this phenomenon, making the jet glide on top of a shear-thinning liquid layer, or whether an entrained air layer is responsible. Herein we...
متن کاملLeaping shampoo and the stable Kaye effect
Shear-thinning fluids exhibit surprisingly rich behaviour. One example is the Kaye effect which occurs when a thin stream of a solution of polyisobutylene in decalin is poured into a dish of the fluid. As pouring proceeds, a small stream of liquid occasionally leaps upward from the heap. This surprising effect, which lasts only a second or so, is named after its first observer, Kaye, who could ...
متن کامل1 Mems Lubricating Air Bubble Array
Single atomic monolayer (SAM) technology will be used to design an air bubble array for the lubrication of MEMS devices with sliding and rotating parts. Patterning a matrix of hydrophobic patches on a hydrophilic substrate will result in an array of air bubbles formed by the repulsive behavior of water molecules with the hydrophobic surfaces. The performance of the air bubble array will be dete...
متن کاملThe Mechanics of a Hydrogel Contact Lens on the Human Eye with a Lubricating Tear Layer
The mechanics governing the fit of a soft contact lens on the eye are examined through the development of a finite element analysis model. A linearly elastic lens is placed on a rigid eye with a lubricating viscoelastic tear layer. The mechanics of fit are described in terms of the pressure distribution through the tear layer, the contact pressure at the lens/tear interface, the tear film thick...
متن کاملHydrodynamic thickening of lubricating fluid layer beneath sliding mesothelial tissues.
The delicate mesothelial surfaces of the pleural space and other serosal cavities slide relative to each, lubricated by pleural fluid. In the absence of breathing motion, differences between lung and chest wall shape could eventually cause the lungs and chest wall to come into contact. Whether sliding motion keeps lungs and chest wall separated by a continuous liquid layer is not known. To expl...
