(Photo by Randy Montoya) Pavel Bochev (in Sandia’s Computational Mathematics Dept.) has received an EO Lawrence Award for his pioneering theoretical and practical advances in numerical methods for partial differential equations. “This is the [...]

Sandia Wins Funding for Programming In Situ Data Analysis/Visualization

Sandia was recently awarded DOE Advanced Scientific Computing Research (ASCR) funding to develop a framework for in situ data management, analysis, and visualization. Sandia’s approach provides a mechanism for specifying the structure and use of data, decouples code specification from optimization, and facilitates the expression of complex scientific workflows—thereby enabling scientists to develop high-performance, portable codes [...]

Sandia Optical Diagnostics Researcher Wins DOE Early Career Award

Sandia Combustion Research Facility (CRF) scientist Christopher Kliewer (in Sandia’s Combustion Chemistry Dept.) won a DOE Office of Science (SC) Early Career Research Program award to develop new optical diagnostics to study interfacial combustion interactions that are major sources of pollution and vehicle inefficiency. The funding opportunity for researchers in universities and DOE national laboratories, [...]

Sandia Researchers Are First to Measure Thermoelectric Behavior of a Nanoporous Metal-Organic Framework

Thermoelectric devices convert heat to electricity and have no moving parts, making them extremely attractive for cooling and energy harvesting applications. Thermoelectric metal-organic frameworks (MOFs) could take these advantages a step further with improved performance, smaller size and flexible designs. MOFs have a crystalline structure that resembles molecular scaffolding, consisting of rigid organic molecules linked [...]

Sandia Participates in Office of Science’s National Science Bowl

The Department of Energy Office of Science’s National Science Bowl® (NSB) is a nationwide academic competition that tests middle and high school student teams’ knowledge in all areas of science and mathematics. The DOE created the National Science Bowl® in 1991 to encourage students to excel in mathematics and science and to pursue careers in [...]

Turbulent Mixed-Mode Combustion Studied in a New Piloted Burner

Isometric solid model of the piloted burner (left) and cutaway schematic (right) with dimensions in millimeters. Flame stability is an important trait of practical combustors that impacts combustion emissions and the ability of the combustor to operate effectively with changing fuel and oxidizer compositions and flow rates. Fuel and oxidizer in combustion systems [...]

Resolving a Key to How Stars Transmit Energy

Sandia physicist Jim Bailey observes a wire array that will heat foam to roughly 4 million degrees until it emits a burst of X-rays that heats a foil target to the interior conditions of the sun. Working at temperatures matching the interior of the sun, researchers at Sandia National Laboratories’ Z machine have [...]

Predicting Pressure-Dependent Combustion Chemical Reactions

The Combustion Research Facility (CRF) at Sandia’s Livermore, California, site. 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 [...]

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 [...]
