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. ...
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 ...
Scientists find a way to distinguish the aerosol particle signal from the weather noise
(Phys.org)—Scientists developed a modeling shortcut to dial in a clearer atmospheric particle signal. A research team from the Scripps Institute of Oceanography, the University of Washington, and Pacific ...
Small and efficient: Water nanodroplets cool biomolecules ultrafast
Researchers of the Max-Born-Institute at Berlin, Germany, have observed how biomolecules transfer energy into extremely small water droplets in their environment. A water shell consisting of only 3 water ...
Self-filling water bottle takes cues from desert beetle
Scotch tape finds new use as grasping 'smart material'
(Phys.org)—Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material."
Mosquitos fail at flight in heavy fog
Mosquitos have the remarkable ability to fly in clear skies as well as in rain, shrugging off impacts from raindrops more than 50 times their body mass. But just like modern aircraft, mosquitos also are grounded when the ...
Creating a coating of water-repellent microscopic particles to keep ice off airplanes
To help planes fly safely through cold, wet, and icy conditions, a team of Japanese scientists has developed a new super water-repellent surface that can prevent ice from forming in these harsh atmospheric conditions. Unlike ...
Leidenfrost effect impacted by temperature, surface type, researchers find
Physicists at the University of Bath have been investigating a strange phenomenon that allows water droplets to levitate and even climb uphill.
Droplet response to electric voltage in solids exposed
For the first time, scientists have observed how droplets within solids deform and burst under high electric voltages.
How highway bridges sing—or groan—in the rain to reveal their health
A team of BYU engineers has found that by listening to how a highway bridge sings in the rain they can determine serious flaws in the structure.
Research addresses complex multiscale and multiphase cloud physics problems
(Phys.org)—Lian-Ping Wang, professor of mechanical engineering and joint professor of physical ocean science and engineering at the University of Delaware, recently published an invited critical review ...
Freezing water droplets form sharp ice peaks
Photos reveal how water droplets placed on a cold surface freeze to a sharp point that sprouts a "forest" of tree-like ice crystals.
'Bed of nails' material for clean surfaces
(Phys.org)—Scientists at the University of Twente's MESA+ Institute for Nanotechnology have developed a new material that is not only extremely water-repellent but also extremely oil-repellent. It contains ...
