Sandia's ASCI red, world's first teraflop supercomputer, is decommissioned

DOE/Sandia National Laboratories
Business Announcement

On a table in a small meeting room at Sandia National Laboratories rested a picture of the deceased -- a row of identical cabinets that formed part of the entity known as ASCI Red, the world's first teraflop supercomputer. Still one of the world's 500 fastest supercomputers after nine years, ASCI Red was being decommissioned.

Sandia preemptive spark helps find intermittent electrical short circuits in airplanes

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A preemptive spark lasting for nanoseconds that helps find potentially dangerous intermittent electrical short circuits hidden in the miles of wiring behind the panels of aging commercial airliners has been patented by Sandia National Laboratories.

'Prettier world' of computer modeling provides key details, says Sandia researcher

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Nanotechnology simulations show what experiments miss. Taking issue with the perception that computer models lack realism, Sandia National Laboratories researcher Eliot Fang told members of the Materials Research Society that simulations of the nanoscale provide researchers more detailed results - not less - than experiments alone.

Desalination roadmap seeks technological solutions to increase the nation's water supply

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories researchers Pat Brady and Tom Hinkebein are putting the final touches on the updated Desalination and Water Purification Roadmap -- "Roadmap 2" -- that should result in more fresh water in parts of the world where potable water is scarce. The first roadmap identified overall goals and areas of desalination research and was submitted to Congress in 2003.

Raiders of the lost dimension

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A team of scientists working at the National High Magnetic Field Laboratory's Pulsed Field Facility at Los Alamos has uncovered an intriguing phenomenon while studying magnetic waves in barium copper silicate, a 2,500-year-old pigment known as Han purple. The researchers discovered that when they exposed newly grown crystals of the pigment to very high magnetic fields at very low temperatures, it entered a rarely observed state of matter.

Address water scarcity, water quality issues around the world now, Sandia/CSIS report says

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Now is the time to address the devastating effects of increasing water scarcity and declining water quality around the world, according to a recently released white paper written jointly by Sandia National Laboratories and the Washington think tank Center for Strategic and International Studies (CSIS).

Repeatable low-breakdown voltage antifuses enabled through a Sandia-developed dielectric thin film

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Researchers at Sandia National Laboratories have developed an inexpensive, reliable and easy-to-manufacture class of dielectric films that have the capability of enabling programmable antifuses on integrated circuits (IC) at less cost and using easier-to-manufacture methods.

Laboratory scientists study soot in megacity pollution

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration. The March campaign was designed to examine the chemical and physical transformations of gases and aerosols in the polluted outflow from the Mexico City metropolitan area.

Experiments examine hydrogen-production benefits of clean coal burning

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Experiments are underway at Sandia to optimize the combustion of coal to produce the most energy and the least possible pollution. Researchers say coal may remain competitive with other fuels after figuring in the possible benefits of sequestering carbon dioxide and generating both electricity and hydrogen in coal-fired power plants.
