Sandia Scientist, Colleague, Suggest Meteor Plumes Causing Transient Dark Spots In Upper Atmosphere

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Calculations of a Sandia National Laboratories physicist and his Texas-based colleague may offer additional insight into a decade-old controversy as to whether up to 30,000 house-sized snowballs, or icy comets, are striking Earth each day.

Sandia Labs Developing Means To Sniff Out Landmines

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories has joined the effort to rid the planet of what some people have called its worst form of pollution -- landmines. Sandia's detection and de-mining work ranges from chemical sensitivity, backscattered x-rays, quick-hardening foam, with robotic vehicles to support the technologies.

Like A Hippopotamus Turning On A Dime: Sandia “Photonic Crystal” Bends Microwaves Around Tight Corner

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A Sandia "photonic lattice" -- a kind of artificial crystal - - has bent microwaves around 90-degree corners, within radii smaller than a wavelength, and with almost 100 percent transmission efficiency, offering promise of cheaper and more efficient communications.

Sandia Creates Microtransmission; Vastly Increases Power Of Microengine

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A microtransmission the size of a grain of sand has been fabricated at Sandia National Laboratories. Occupying an area of one square millimeter, it provides a gear-down ratio of 3 million:1. Attached to a microengine (also the size of a grain of sand) it theoretically can move a one-pound object.

Orbits Of Satellites, Accuracy Of Missiles Improved Merely By Shifting Weights

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A missile or space ship, spinning like a football or Olympic diver as it reenters atmosphere, can be stabilized merely by shifting weights within its shell. The method may improve orbits of satellites.

Sniffing Danger: Sandia Tests Explosive Detection Portal At Airport

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Some airline passengers visiting the main security checkpoint at the Albuquerque International Airport this week are being asked to try out tomorrow's technology for combating terrorism - an "explosives -detection portal" under development at Sandia National Laboratories for the Federal Aviation Adminstration (FAA). The "portal" is intended to help prevent airliner hijackings and bombings.

Sandia Patents Extreme Ultraviolet Source

DOE/Sandia National Laboratories
Peer-Reviewed Publication

The realization that atomic gas clusters could serve as part of a sort of ³light bulb² that emits extreme ultraviolet (EUV) light when laser-heated has inspired a recently patented invention at Sandia National Laboratories. This light source enables research development of EUV lithography to pattern faster, more memory-dense microchips.
