Rice University theory predicts formation of conductive sub-nano ℠wires´ in two-dimensional materials A new material structure predicted at Rice University offers the tantalizing possibility of a signal path smaller than the nanowires for advanced electronics now under development at Rice and elsewhere. Theoretical physicist Boris Yakobson and postdoctoral fellow Xiaolong Zou were investigating the atomic-scale properties of two-dimensional materials when they found to their...

Real-Time CT-Scan Test Rig For Ceramic Composites At Ultrahigh Temperatures Developed
2012-12-10 16:41:08

Lawrence Berkeley National Laboratory Advanced ceramic composites can withstand the ultrahigh operational temperatures projected for hypersonic jet and next generation gas turbine engines, but real-time analysis of the mechanical properties of these space-age materials at ultrahigh temperatures has been a challenge — until now. Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first testing facility...

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...

Helping Aircraft Fly Further Using Hypergravity
2012-11-05 10:24:47

ESA ESA research has helped to develop an aircraft-grade alloy that is twice as light as conventional nickel superalloys while offering equally good properties. The path to creating this alloy required research under all types of gravity. Airlines are always looking for ways to save fuel by cutting down on weight without sacrificing safety. Generally, cutting weight by 1% will save up to 1.5% in fuel. For commercial airlines, this saving quickly adds up, offering cheaper flights and...

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...

vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
