New semiconductor alloy's 'crazy physics' makes it a possible photovoltaic power source for satellites

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Scientists at the Department of Energy’s Sandia National Laboratories are researching ways to use a new semiconductor alloy, indium gallium arsenide nitride (InGaAsN), as a photovoltaic power source for space communications satellites and for lasers in fiber optics.

Not Cartier, but non-allergenic and long-lasting: World’s first diamond micromachines created at Sandia

DOE/Sandia National Laboratories
Peer-Reviewed Publication

You can't give them to your loved one on Valentine's Day, and they're a bit too small to be a girl's best friend, but Sandia National Laboratories has created what are believed to be the world's first diamond micromachines. The biocompatible machines are etched in a manner compatible with current silicon chip manufacturing techniques.

Human factors experts at Sandia take new approach to studying human failure in engineered systems

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Taking a lesson from nuclear weapons surety, Chris Forsythe and Caren Wenner of the Department of Energy’s Sandia National Laboratories have come up with a new approach to studying how and why engineered systems fail due to the actions or inaction of humans.

Palestinian and Israeli environmental researchers collaborate in Sandia program

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Israeli and Palestinian environmental resarchers are collaborating and sharing information through a year-old project initiated by the Cooperative Monitoring Center at the Department of Energy's (DOE) Sandia National Laboratories.

Three Sandia experimental wind turbines spin in Texas panhandle

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Three small wind turbines spinning in the Texas Panhandle as part of a series of experiments being conducted by the Department of Energy's Sandia National Laboratories promise to answer some big questions researchers have long asked about how to harness wind power to generate electricity .

Of skiers, snowboarders, and other terrorists: Avalanche victims found four times faster with robotic 'swarm' search technique, researcher says

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A skier or snowboarder buried under an avalanche can suffocate in half an hour. Fortunately, the same algorithm developed to help a swarm of tiny robots locate the point source of a chemical or biological attack will find the downed recreationist in 1/4 the time of any known method.

Moving up from the far, far outside: Sandia's homemade computer hook-up grows, prospers

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Among the 500 listings of the world’s fastest supercomputers is a peculiar entry at 44th post. Rather than being spawned by the familiar giant manufacturers that occupy all other positions, the 44th-positioned machine is described as "self- made."

Sandia micromirrors may be part of Next Generation Space Telescope

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Micromirrors being developed by the Department of Energy’s Sandia National Laboratories may one day be part of the Next Generation Space Telescope (NGST), the successor to the Hubble that will peruse the universe looking for remnants from the period in which the first stars and galaxies formed

Earth-bound 'star' impersonates black hole, neutron star:Z, which reaches temperatures of the Sun, to help astronomers interpret Chandra data

DOE/Sandia National Laboratories
Peer-Reviewed Publication

In an inconspicuous, flat-roofed building on the high desert of New Mexico, a machine that creates temperatures rivaling those of the sun is helping physicists examine up-close what happens to iron in the grip of black holes and neutron stars. Data should help astronomers interpret images from the billion-dollar Chandra X-ray observatory now orbiting Earth.

Sandia portable chemical sensor system promises new way of detecting underwater explosives

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A portable chemical sensor system the size of a soccer ball, being developed by scientists at the Department of Energy's Sandia National Laboratories, promises a new way of detecting and identifying even the smallest traces of explosives under water — whether in a rice paddy or deep in the ocean.
