Engineers create 'superomniphobic' texture capable of repelling all liquids
(Phys.org) —A pair of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created the first surface texture that can repel all liquids, no matter what material the surface ...
New super waterproof surfaces cause water to bounce like a ball
(Phys.org) —In a basement lab on BYU's campus, mechanical engineering professor Julie Crockett analyzes water as it bounces like a ball and rolls down a ramp.
Physicists break theoretical time barrier on bouncing droplets (w/ Video)
Those who study hydrophobic materials—water-shedding surfaces such as those found in nature and created in the laboratory—are familiar with a theoretical limit on the time it takes for a water droplet ...
Jumping droplets help heat transfer
Many industrial plants depend on water vapor condensing on metal plates: In power plants, the resulting water is then returned to a boiler to be vaporized again; in desalination plants, it yields a supply of clean water. ...
Chemical dial controls attraction between water-repelling molecules
Fear of water may seem like an irrational hindrance to humans, but on a molecular level, it lends order to the world.
Quenching the world's water and energy crises, one tiny droplet at a time
In the Namib Desert of Africa, the fog-filled morning wind carries the drinking water for a beetle called the Stenocara.
Adhesion disturbed by noise
Imagine a solid ball rolling down a slightly inclined ramp. What could be perceived as child's play is the focus of serious theoretical research by Manoj Chaudhury and Partho Goohpattader, two physicists ...
Lubricated, nanotextured surfaces improve performance of condensers in power and desalination plants, research finds
Condensers are a crucial part of today's power generation systems: About 80 percent of all the world's powerplants use them to turn steam back to water after it comes out of the turbines that turn generators. They are also ...
Researchers find new way to mimic the color and texture of butterfly wings
(Phys.org)—The colors of a butterfly's wings are unusually bright and beautiful and are the result of an unusual trait; the way they reflect light is fundamentally different from how color works most of ...
Microcantilevers are masters of measurement
(PhysOrg.com) -- Devices that look like tiny diving boards are a launching platform for research that could improve detergents and advance understanding of disease.
Getting ice, frost off planes problematic
The buildup of ice on surfaces can cause problems in many situations: On airplane wings or on their engine turbine blades, ice can both add weight and interfere with a wings lift, which can make it impossible ...
Loves Me, Loves Me Not: Researchers Discover New Method for Measuring Hydrophobicity at the Nanoscale
(PhysOrg.com) -- Researchers at Rensselaer Polytechnic Institute have discovered a new, more precise method for measuring how much — or how little - nanoscale interfaces love water.
Researchers develop a way to cause static self-assembly using magnets and ferrofluids
Explained: Hydrophobic and hydrophilic
Sometimes water spreads evenly when it hits a surface; sometimes it beads into tiny droplets. While people have noticed these differences since ancient times, a better understanding of these properties, and ...
