Researchers Use Liquid Metal To Build 3-D Structures
2013-07-09 14:28:19

North Carolina State University [ Watch The Video 3D Printing of Liquid Metals at Room Temperature ] Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature. "It's difficult to create structures out of liquids, because liquids want to bead up. But we've found that a liquid metal alloy of gallium and indium reacts to the oxygen in the air at...

Synchrotron Helps Reveal Structure Of A Supercooled Liquid
2013-07-05 10:54:23

Saarland University The experimental work, which was performed at the German Electron Synchrotron Facility (DESY) in Hamburg, involved levitating hot metal droplets and observing them as they cooled by irradiating them with x-rays from one of the world's strongest x-ray sources. The research work is funded by the German Research Foundation (DFG) and the results have just been published in Nature Communications. Supercooled liquids demonstrate some interesting phenomena when they are...

Researchers at the University of Sheffield have found a more efficient way to dry products for food manufacture, using tiny, hot bubbles. Instead of boiling a product to evaporate water - the most common technique used by industry - the Sheffield team injected hot microbubbles through the liquid, causing the water to evaporate without boiling. Professor Will Zimmerman, who led the study, explains: "We've applied this principle, called 'cold boiling' to separate water from methanol....

Missing Link Between Mechanical And Structural Properties Of Glass Established By Researchers
2013-04-10 12:47:08

Deutsches Elektronen-Synchrotron The craft of glassmaking extends way back in time. It was over five-thousand years ago when mankind learned how to make glass. Even prior to this discovery, humans had been using naturally occurring glass for tool making. Despite this long and rich history and widespread use of glass, surprisingly little is known about the interplay between the mechanical properties of glasses and their inner structures. For the first time, researchers from Amsterdam...

Scientists have unearthed a new dynamic process induced by strong electric fields in thin liquid crystal cells Liquid crystal displays are ubiquitous. Now, Polish physicists have demonstrated that the application of a very strong alternating electric field to thin liquid crystal cells leads to a new distinct dynamic effect in the response of the cells. The theory of spatio-temporal chaos explains this effect. It was elucidated by Wojciech Jeżewski and colleagues from the...

Liquid Metals Have Different Breaking Points
2012-11-26 08:55:23

DOE/Lawrence Berkeley National Laboratory Mathematical methods developed by a Berkeley Lab researcher help explain why liquid metals have wildly different breaking points, depending on how they are made Metallic glass alloys (or liquid metals) are three times stronger than the best industrial steel, but can be molded into complex shapes with the same ease as plastic. These materials are highly resistant to scratching, denting, shattering and corrosion. So far, they have been used in a...

Ordered Atoms Found In Glass Materials
2012-10-02 15:10:29

Scientists at the U.S. Department of Energy´s (DOE) Ames Laboratory have discovered the underlying order in metallic glasses, which may hold the key to the ability to create new high-tech alloys with specific properties. Glass materials may have a far less randomly arranged structure than formerly thought. Over the years, the ideas of how metallic glasses form have been evolving, from just a random packing, to very small ordered clusters, to realizing that longer range chemical and...

New Coating Boots Out Biofilms For Good
2012-07-30 16:23:35

Slippery technology shown to prevent more than 99 percent of harmful bacterial slime from forming on surfaces Biofilms may no longer have any solid ground upon which to stand. A team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface. Biofilms stick to just about everything, from copper pipes to steel ship hulls to glass catheters. The slimy coatings are more than just a nuisance, resulting in decreased energy...

Weird World Of Water Just Got Weirder
2011-11-09 13:59:02

Strange, stranger, strangest! To the weird nature of one of the simplest chemical compounds -- the stuff so familiar that even non-scientists know its chemical formula -- add another odd twist. Scientists are reporting that good old H2O, when chilled below the freezing point, can shift into a new type of liquid. The report appears in ACS' Journal of Physical Chemistry B. Pradeep Kumar and H. Eugene Stanley explain that water is one weird substance, exhibiting more than 80 unusual...

Wine swirling, heart valve action, detonating stars, and more The latest news and discoveries from the science of fluid motion will be featured at the 64th Annual Meeting of the American Physical Society's (APS) Division of Fluid Dynamics (DFD), held November 20-22, 2011, at the Baltimore Convention Center near the scenic Inner Harbor section of Baltimore, Md. Researchers from around the globe will present noteworthy research covering the intricacies of flight, the workings of the human...
