The hidden culprit killing lithium-metal batteries from the inside

ALBUQUERQUE, N.M. — For decades, scientists have tried to make reliable lithium-metal batteries. These high-performance storage cells hold 50% more energy than their prolific, lithium-ion cousins, but higher failure rates and safety problems like fires and explosions have crippled commercialization efforts. Researchers have hypothesized why the devices fail, but direct evidence has been sparse. Now, […]

Setting gold and platinum standards where few have gone before

ALBUQUERQUE, N.M. — Like two superheroes finally joining forces, Sandia National Laboratories’ Z machine — generator of the world’s most powerful electrical pulses — and Lawrence Livermore National Laboratory’s National Ignition Facility — the planet’s most energetic laser source — in a series of 10 experiments have detailed the responses of gold and platinum at […]

Black engineer awards expand Sandia Labs spotlight

ALBUQUERQUE, N.M. — Ten Sandia National Laboratories engineers received Black Engineer of the Year Awards, including Most Promising Scientist, Modern Technology Leaders and Science Spectrum Trailblazers. Honorees include Sandia systems, chemical, computer, electrical, petroleum, manufacturing and mechanical engineers who excel in their respective fields, powering innovation while flexing their technological muscles for U.S. national security.

Sandia to put nuclear waste storage canisters to the test

ALBUQUERQUE, N.M. — Sandia National Laboratories is outfitting three 22.5-ton, 16.5-feet-long stainless-steel storage canisters with heaters and instrumentation to simulate nuclear waste so researchers can study their durability. The three canisters, which arrived in mid-November and have never contained any nuclear materials, will be used to study how much salt gathers on canisters over time. […]

Sandia tests distillery’s hand sanitizer developed to address severe shortage

ALBUQUERQUE, N.M. — Distillery-developed hand sanitizer is leaving a New Mexico warehouse as quickly as it disappeared from grocery stores after Sandia National Laboratories helped confirm the product meets all federal requirements for distribution. In response to the severe, widespread shortage during the COVID-19 pandemic, Wayward Sons Craft-Distillery in Santa Fe, New Mexico, reconfigured its […]

Sandia establishes collaborative research facility for low-temperature plasmas

ALBUQUERQUE, N.M. —  Sandia National Laboratories is setting up a collaborative facility to help researchers worldwide study low-temperature plasmas, the most pervasive state of matter in the universe. The 5-year, $5.5 million project, called the Sandia Low Temperature Plasma Research Facility, is sponsored by the Department of Energy’s Office of Science. Participants will be selected […]

Sandia research focuses on ‘switching on’ iron in clay minerals

ALBUQUERQUE, N.M. — Sandia National Laboratories researchers have discovered the mechanism to “switch on” iron residing in clay mineral structures, leading to the understanding of how to make iron reactive under oxygen-free conditions. This research will help scientists understand and predict how contaminants, such as arsenic, selenium and chromium, move through the environment and enter […]

Portable gas detection shrinks to new dimensions

ALBUQUERQUE, N.M. — A sensor for detecting toxic gases is now smaller, faster and more reliable. Its performance sets it up for integration in a highly sensitive portable system for detecting chemical weapons. Better miniature sensors can also rapidly detect airborne toxins where they occur, providing key information to help emergency personnel respond safely and […]

Thwarting oil-pipeline corrosion by identifying a nanoscale villain

ALBUQUERQUE, N.M. — Steel pipes rust and eventually fail. To preempt disasters, oil companies and others have created computer models to predict when replacement is needed. But if the models themselves go wrong, they can be modified only through experience, a costly problem if detection comes too late. Now, researchers at Sandia National Laboratories, the […]

Deconstructing deleterious soot

LIVERMORE, Calif. — In most situations, breaking things apart isn’t the best way to solve a problem. However, sometimes the opposite is true if you’re trying to characterize complex chemical compounds. That’s what Sandia National Laboratories scientists Nils Hansen and Scott Skeen did to definitively identify pollution-causing soot precursors in a flame. The researchers discovered […]

Sandia microneedles technique may mean quicker diagnoses of major illnesses

ALBUQUERQUE, N.M. — When people are in the early stages of an undiagnosed disease, immediate tests that lead to treatment are the best first steps. But a blood draw — usually performed by a medical professional armed with an uncomfortably large needle — might not be quickest, least painful or most effective method, according to […]

Large supercrystals promise superior sensors

ALBUQUERQUE, N.M. — Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve the detection sensitivity for chemicals in explosives or drugs. “Our supercrystals have more sensing capability than regular spectroscopy instruments currently in use, just like a […]

A splash of detergent makes catalytic compounds more powerful

ALBUQUERQUE, N.M — Researcher David Rosenberg examines images of a white powder under a powerful scanning electron microscope. Up close, the powder looks like coarse gravel, a heap of similar but irregular chunks. Then he looks at a second image — the same material produced by colleague Hongyou Fan instead of purchased from a catalog […]

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 […]
