The shark skin effect is drag reduction in fluid flow due to a certain design of surface microstructure, namely, due to riblets mimicking shark scale. When a shark swims in water, a special design of riblets on its skin results… Read More
From our same paper, a historical review: “The theory of wetting represented by Equation (1) was formulated for the first time by Thomas Young in 1805 in his essay “On the Cohesion of Fluids” [8]. The essay does not contain… Read More
Surface tension is a fundamental concept in surface physics and chemistry. The most common definition of surface tension is that it is a force acting along a line of unit length parallel to the surface, but perpendicular to the line…. Read More
There is a classical theory of an “entropic” elastic force in an ideal polymer chain, whose shape is modeled as a random walk. The elastic force as a function of the distance between the ends of the chain is calculated… Read More
1. Here we discuss various ideas about wetting, ice adhesion and entropic forces, and how these ideas can be applied to novel superhydrophobic and icephobic concrete: R Ramachandran, M Kozhukhova, K Sobolev, M Nosonovsky Anti-Icing Superhydrophobic Surfaces: Controlling Entropic Molecular Interactions to Design… Read More
