For the first time, scientists have observed how droplets within solids deform and burst under high electric voltages. This is important, the Duke University engineers who made the observations said, because it explains a major reason why such materials as insulation for electrical power lines eventually fail and cause blackouts. This observation not only helps scientists develop better insulation materials, but could also lead to such positive developments as "tunable" lenses for eyes....

Rice University physicists find reversible way to alter VO2“²s unique electronic about-face If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you´ve never heard of. It´s a metal. It´s an insulator. It´s a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to reversibly alter VO2“²s electronic properties by treating it with one of the...

Berkeley Lab researchers and their colleagues demonstrate unique new materials for innovative electronic and magnetic applications Strange new materials experimentally identified just a few years ago are now driving research in condensed-matter physics around the world. First theorized and then discovered by researchers at the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues in other institutions, these “strong 3-D topological...

As a result of a joint intensive work of several groups from five different countries, including Basque Country, a new wide class of topological insulators –materials that are insulators  in the bulk but conductors at the surface– with technologically very promising properties has been discovered. Topological insulators, first observed in 2007, are materials that, while being an insulator inside or in the bulk, behave as metals at the surface. Their unique properties can...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
