Tiny Bubbles In Your Metallic Glass May Be Sign Of Trouble

Johns Hopkins University Bubbles in a champagne glass may add a festive fizz to the drink, but microscopic bubbles that form in a material called metallic glass can signal serious trouble. In this normally high-strength material, bubbles may indicate that a brittle breakdown is in progress. That´s why Johns Hopkins researchers used computer simulations to study how these bubbles form and expand when a piece of metallic glass is pulled outward by negative pressure, such as the...

New research Shows 'Perfect Twin Boundaries' Are Not So Perfect

University of Vermont One of the basic principles of nanotechnology is that when you make things extremely small–one nanometer is about five atoms wide, 100,000 times smaller than the diameter of a human hair–they are going to become more perfect. "Perfect in the sense that their arrangement of atoms in the real world will become more like an idealized model," says University of Vermont engineer Frederic Sansoz, "with smaller crystals–in for example, gold or...

WATCH VIDEO: [Moving Toward High Shape Resolution] Michael Harper for redOrbit.com — Your Universe Online When the iPhone was first released in 2007, one of its best features was the ability to run web applications, becoming a pocketable computer with many different uses. This ability was amplified in 2008 with the introduction of the App Store. This wasn´t only a phone; it was also a browser, a GPS, a camera, a networking tool, etc. It´s been nearly six years since this...

Sandia National Laboratories researchers Lisa Deibler and Arthur Brown had a ready-made problem for their computer modeling work when they partnered with the National Nuclear Security Administration´s Kansas City Plant to improve stainless steel tubing that was too hard to meet nuclear weapon requirements. When steel is too hard it becomes brittle, so the plant ended up getting new tubing. However, Deibler said KCP needed a backup in case it couldn´t find replacements in time to...

Lead is a chemical element in the periodic table that has the symbol Pb (L. Plumbum) and atomic number 82. A soft, heavy, toxic and malleable poor metal, lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air. Lead is used in building construction, lead-acid batteries, bullets and shot, and is part of solder, pewter, and fusible alloys. Lead has the highest atomic number of all stable elements. (But see the article on Bismuth, which has a half life so long it can...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
