Absorbing
Hydrogen Fluoride Gas to Enhance Crystal Growth
Dec. 10, 2009 Two scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a method to control the buildup of hydrogen fluoride gas during the growth of precision crystals needed for applications such as superconductors, optical devices, and microelectronics. The invention — by Vyacheslav Solovyov and Harold Wiesmann and recently awarded U.S. Patent number 7,622,426 — could lead to more efficient production and improved performance of these materials. |

U.S
Air Force/Lockheed Martin-Led Team Successfully Complete
Environmental Testing Of First-Of-Its-Kind Missile Warning
Satellite
Dec. 01, 2009 A joint U.S. Air Force/Lockheed Martin [NYSE: LMT]-led team announced today that it has successfully completed thermal vacuum testing of the first Space Based Infrared System (SBIRS) geosynchronous (GEO-1) satellite, one of the most significant program milestones that validates spacecraft performance in a simulated space environment. |

Researchers Discover That Defects in Carbon Nanotubes Could Lead
to Improved Charge and Energy Storage Systems
Nov. 20, 2009 A recent discovery made by UC San Diego engineers could lead to carbon nanotube-based supercapacitors that could do just this. Prabhakar Bandaru, a professor in the UCSD Department of Mechanical and Aerospace Engineering, along with graduate student Mark Hoefer, have found that artificially introduced defects in nanotubes can aid the development of supercapacitors. |

Scientists
Detect 'Fingerprint' of High-Temp Superconductivity Above
Transition Temperature
Aug. 27, 2009 A team of U.S. and Japanese scientists has shown for the first time that the spectroscopic “fingerprint” of high-temperature superconductivity remains intact well above the super chilly temperatures at which these materials carry current with no resistance. This confirms that certain conditions necessary for superconductivity exist at the warmer temperatures that would make these materials practical... |

Sandia
research points way toward chameleon-like camouflage
Apr. 07, 2009 Sandia National Laboratories researchers have demonstrated that, in theory, they could cause synthetic materials to change color like fish do. “Camouflage outfits that blend with a variety of environments without need of an outside power source — say, blue when at sea and then brown in a desert environment — is where this work could eventually lead,” says principal investigator George Bachand. “Or the same effect could be used in fabricating chic civilian clothing that automatically changes color ... |

Sandia’s
diamond-like films on board NASA satellite
Feb. 17, 2009 Diamond-like carbon films created at Sandia National Laboratories are helping probe the far boundaries of the solar system as part of a NASA mission to study how the sun’s solar wind interacts with the interstellar medium – the matter that exists between the stars within a galaxy. The films are in the low-energy sensor (IBEX-Lo) on board NASA’s Interstellar Boundary Explorer (IBEX), which lifted off in October on a mission to study the farthest fringes of the solar system. |

High Frequency Amplifier Harnesses Millimeter Waves in Silicon
for Fast Wireless
Feb. 11, 2009 New imaging and high capacity wireless communications systems are one step closer to reality, thanks to a millimeter wave amplifier invented at the University of California, San Diego and unveiled on Feb 11, 2009 at the prestigious International Solid-State Circuits Conference (ISSCC) in San Francisco, Calif. |

Closing
the Gap Between High-Speed Data Transmission and Processing
Jan. 27, 2009 Electrical engineers at the University of California, San Diego have achieved world-record speeds for real-time signal processing in an effort to meet ambitious goals set by the Defense Advanced Research Projects Agency (DARPA) to develop the first Terabit-scale technology for optical processing. The technology could have widespread ramifications for networking, computing, defense and other industries. |

Humanities
and High Performance Computers Connect at NERSC
Dec. 23, 2008 High performance computing and the humanities are finally connecting — with a little matchmaking help from the Department of Energy (DOE) and the National Endowment for the Humanities (NEH). Both organizations have teamed up to create the Humanities High Performance Computing Program, a one-of-a-kind initiative that gives humanities researchers access to some of the world’s most powerful supercomputers. |

Physicists
Set New Record for Quantum Memory Storage
Dec. 08, 2008 Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms. Though the information remains usable for just milliseconds, even that short lifetime should be enough to allow transmission of data from one quantum repeater to another on an optical network. |

holographic method could be used for lab-on-a-chip technologies
Dec. 02, 2008 Researchers at Purdue University have developed a technique that uses a laser and holograms to precisely position numerous tiny particles within seconds, representing a potential new tool to analyze biological samples or create devices using nanoassembly. The technique, called rapid electrokinetic patterning, is a potential alternative to existing technologies because the patterns can be more quickly and easily changed, said mechanical engineering doctoral student Stuart J. Williams. |
