Researchers bridge superconductivity gap
DOE/Los Alamos National LaboratoryPeer-Reviewed Publication
University of California scientists at Los Alamos National Laboratory working with a researcher from Chonnam National University in South Korea have found that magnetic fluctuations appear to be responsible for superconductivity in a compound called plutonium-cobalt-pentagallium (PuCoGa5). The discovery of this "unconventional superconductivity" may lead scientists to a whole new class of superconducting materials and toward the goal of eventually synthesizing "room-temperature" superconductors.

Novel ultrafast laser detection of cancer cells also may improve understanding of stem cells
DOE/Sandia National LaboratoriesPeer-Reviewed Publication
A lightning-fast laser technique, led by Sandia National Laboratories researcher Paul Gourley, has provided laboratory demonstrations of accurate, real-time, high-throughput identification of liver tumor cells at their earliest stages, and without invasive chemical reagents.

Researchers develop fingerprint detection technology
DOE/Los Alamos National LaboratoryPeer-Reviewed Publication
University of California scientists working at Los Alamos National Laboratory have developed a novel method for detecting fingerprints based on the chemical elements present in fingerprint residue. Known as micro-X-ray fluorescence, or MXRF, the technique has the potential to help expand the use of fingerprinting as a forensic investigation tool.

Tiny porphyrin tubes developed by Sandia may lead to new nanodevices
DOE/Sandia National LaboratoriesPeer-Reviewed Publication
Sunlight splitting water molecules to produce hydrogen using devices too small to be seen in a standard microscope. That's a goal of a research team from the National Nuclear Security Administration's Sandia National Laboratories. The research has captured the interest of chemists around the world pursuing methods of producing hydrogen from water.

Taking the terror out of terror: Sandia team re-thinks physical security for homeland defense
DOE/Sandia National LaboratoriesPeer-Reviewed Publication
Anticipating attacks from terrorists, and hardening potential targets against them, is a wearying and expensive business that could be made simpler through a broader view of the opponents' origins, fears, and ultimate objectives, according to studies by the Advanced Concepts Group (ACG) of Sandia National Laboratories.

Snow brings green machining to laboratory
DOE/Los Alamos National LaboratoryPeer-Reviewed Publication
University of California scientists working at Los Alamos National Laboratory have developed a novel machining technique that uses a jet of solid carbon dioxide (CO2) to cool/lubricate the surface of metal parts and remove the cut material during machining. Called Snow-Machining, the process could someday eliminate the use of oil-based or synthetic chemical fluids for metal cutting and metal parts cleaning in industry.

Improving automative coating
DOE/Sandia National Laboratories
"Clearcoats" applied over layers of automotive paint not only enhance automobile appearance, but also serve as a first line of defense against attack from moisture, acid rain, and ultraviolet radiation.

Shaping future
DOE/Sandia National Laboratories
In its next-generation aircraft carrier, the Navy, with assistance from Sandia, is seeking to reduce manpower by 10 to 30 percent, but not by heaping more work on individual sailors. The goal is to use increased technology and improvements
to carrier air wing flight operations, maintenance, and support functions to reduce the overall workload per sailor.

Sampling 'small atmospheres' in the tiny new worlds of MEMS
DOE/Sandia National LaboratoriesPeer-Reviewed Publication
Just as astronomers want to understand the atmospheres of planets and moons, so engineers want atmospheric knowledge of worlds they create that are the size of pinheads, their "skies" capped by tiny glass bubbles. The most advanced sampling procedure known - requiring only picoliters of gas to evaluate the contents of these small atmospheres - is now in place at Sandia National Laboratories.
