New chemical mechanisms identified on road to cleaner, more efficient combustion

LIVERMORE, Calif. — Sandia National Laboratories researchers have identified key chemical mechanisms for the first time that add to the fundamental knowledge of combustion chemistry and might lead to cleaner combustion in engines. Sandia researcher Nils Hansen and former postdoctoral appointee Kai Moshammer focused on low-temperature oxidation of hydrocarbons and other alternative fuels. They identified […]

Reducing power plants’ freshwater consumption with Sandia’s new silica filter

ALBUQUERQUE, N.M. — Power plants draw more freshwater than any other consumer in the United States, accounting for more than 50 percent of the nation’s freshwater use at about 500 billion gallons daily. To help save this water, researchers at Sandia National Laboratories have developed a new silica filter for power plant cooling waters that […]

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 […]

Prototype electrolyte sensor provides immediate read-outs

Painless wearable microneedle device may reduce trips to doctors’ offices ALBUQUERQUE, N.M. — Patients trying to navigate today’s complex medical system with its costly laboratory analyses might prefer a pain-free home diagnostic device, worn on the wrist, that can analyze, continuously record and immediately remedy low electrolyte levels. Runners, athletes in other strenuous sports and […]

Sandia chemist Mitch Anstey to illuminate the Smithsonian Future Is Here Festival

WASHINGTON, D.C. — Chemist Mitch Anstey of Sandia National Laboratories will join Patrick Stewart, George Takei, Brian Greene, Sara Seager and other notable minds from the galaxy of science and science fiction at Smithsonian Magazine’s The Future Is Here Festival on May 16-18 in Washington, D.C. Anstey’s talk, “Let’s Make Light of the Situation,” will […]

American Physical Society names four Sandia fellows

ALBUQUERQUE, N.M. — Four Sandia researchers have been named Fellows of the American Physical Society, an honor that indicates recognition by scientific peers of exceptional contributions to physics. No more than one half of 1 percent of APS membership can be elected in a given year. Those honored are: Charles Barbour, for outstanding contributions to […]
