Resolving a Key to How Stars Transmit Energy

Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have been able to determine experimentally, for the first time in history, iron’s role in inhibiting energy transmission from the center of the sun to near the edge of its radiative band. Because that role is much greater than […]

Predicting Pressure-Dependent Combustion Chemical Reactions

Researchers at Sandia and Argonne national laboratories have demonstrated, for the first time, a method to successfully predict pressure-dependent chemical reaction rates—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 paper describing the work, performed […]

NASA Award for Marginal Ice Zone Observations and Process Experiment (MIZOPEX)

Sandians Mark Ivey and Darin Desilets (both in Sandia’s Geophysics and Atmospheric Sciences Dept.) were included in a NASA Group Achievement Award “for outstanding achievement in executing the MIZOPEX using multiple classes of unmanned aircraft [UASs].” The MIZOPEX campaign used DOE’s Sandia-managed Oliktok Point, Alaska, facilities to investigate unique UAS capabilities, combined with in situ sensing […]

Sandia Magnetized Fusion Technique Produces Significant Results

Sandia Z-Machine researchers have produced a significant fusion-neutron output, using a method fully functioning for only little more than a year. The experimental work is described in a paper “Experimental Demonstration of Fusion-Relevant Conditions in Magnetized Liner Inertial Fusion,” published in the Oct. 6 Physical Review Letters online. A theoretical PRL paper, published on the […]

Diamond Plates Create Nanostructures through Pressure, Not Chemistry

In a recent Nature Com­munications paper, Sandia researcher Hongyou Fan (at Sandia’s Advanced Materials Laboratory) and colleagues have achieved a start toward using mechanical force to process nanoparticles more subtly than the most advanced chemistry. Their newly patented method uses simple pressure—a kind of high-tech embossing—to produce finer and cleaner results in forming silver nanostructures […]
