The destructive effects of supercooled liquid water on airplane safety and climate models

ALBUQUERQUE, N.M. — Supercooled  water sounds smooth enough to be served at espresso bars, but instead it hangs out in Earth’s atmosphere, unpredictably freezing on airplane wings and hampering the simulations of climate theorists. To learn more about this unusual state of matter, Sandia National Laboratories atmospheric scientist Darielle Dexheimer and colleagues have organized an expedition to fly huge tethered balloons in […]

Cleaning concrete contaminated with chemicals

ALBUQUERQUE, N.M. – In March 1995, members of a Japanese cult released the deadly nerve agent sarin into the Tokyo subway system, killing a dozen people and injuring a thousand more. This leads to the question: What if a U.S. transportation hub was contaminated with a chemical agent? The hub might be shut down for […]

Sandia researcher Melissa Teague awarded Presidential Early Career Award

PECASE is highest US honor for early-stage researchers ALBUQUERQUE, N.M. — Sandia National Laboratories materials engineer Melissa Teague has been awarded a Presidential Early Career Award in Science and Engineering (PECASE), the highest honor the U.S. government bestows on science and engineering professionals in the early stages of their research careers. Teague was recognized for […]

Ingenious method enables sharper flat-panel displays at lower energy costs

ALBUQUERQUE, N.M. — A perpetual quest of  manufacturers and viewers is for ever-brighter colors and better images for flat-panel displays built from less expensive materials that also use less electricity. An intriguing method discovered by Sandia National Laboratories researcher Alec Talin and collaborators at the Center for Nanoscale Science and Technology at the National Institute […]

Biological tools create nerve-like polymer network

Crowdsurfing motor proteins create possible prosthetic interface ALBUQUERQUE, N.M. — Using a succession of biological mechanisms, Sandia National Laboratories researchers have created linkages of polymer nanotubes that resemble the structure of a nerve, with many out-thrust filaments poised to gather or send electrical impulses. “This is the first demonstration of naturally occurring proteins assembling chemically […]

Optical diagnostics researcher at Sandia wins DOE Early Career award

LIVERMORE, Calif. — Sandia National Laboratories researcher Christopher Kliewer has won a $2.5 million, five-year Early Career Research Program award from the Department of Energy’s (DOE) Office of Science for his fundamental science proposal to develop new optical diagnostic tools to study interfacial combustion interactions that are major sources of pollution and vehicle inefficiency. Kliewer’s […]

Phonons, arise!

Small electric voltage alters conductivity in key materials ALBUQUERQUE, N.M — Modern research has found no simple, inexpensive way to alter a material’s thermal conductivity at room temperature. That lack of control has made it hard to create new classes of devices that use phonons — the agents of thermal conductivity — rather than electrons […]

The quest for efficiency in thermoelectric nanowires

ALBUQUERQUE, N.M. — Efficiency is big in the tiny world of thermoelectric nanowires. Researchers at Sandia National Laboratories say better materials and manufacturing techniques for the nanowires could allow carmakers to harvest power from the heat wasted by exhaust systems or lead to more efficient devices to cool computer chips. Sandia researchers published a paper, […]

Breakthrough in predictions of pressure-dependent combustion chemical reactions

LIVERMORE, Calif. — Researchers at Sandia and Argonne national laboratories have demonstrated, for the first time, a method to successfully predict pressure-dependent chemical reaction rates. It’s an important breakthrough in combustion and atmospheric chemistry that is expected to benefit auto and engine manufacturers, oil and gas utilities and other industries that employ combustion models. A […]

Turning biological cells to stone improves cancer and stem cell research

‘Zombie’ method also hardens biostructures for mass production ALBUQUERQUE, N.M. — Changing flesh to stone sounds like the work of a witch in a fairy tale. But a new technique to transmute living cells into more permanent materials that defy decay and can endure high-powered probes is widening research opportunities for biologists who are developing […]
