New fog chamber provides testing options that could improve security cameras

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories has developed a fog chamber -- one of the world's largest -- that creates a controlled environment to more easily test security cameras, sensors or other equipment.

RAPTOR turbulent combustion code selected for next-gen supercomputer readiness project

DOE/Sandia National Laboratories
Business Announcement

RAPTOR, a turbulent combustion code developed by Sandia National Laboratories mechanical engineer Joseph Oefelein, was selected as one of 13 partnership projects for the Center for Accelerated Application Readiness (CAAR). CAAR is a US Department of Energy program located at the Oak Ridge Leadership Computing Facility focused on optimizing computer codes for the next generation of supercomputers.

Uncovering the mysteries of cosmic explosions

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

An automated software system developed at Los Alamos National Laboratory played a key role in the discovery of supernova iPTF 14atg and could provide insight, a virtual Rosetta stone, into future supernovae and their underlying physics.

Sandia researchers first to measure thermoelectric behavior by 'Tinkertoy' materials

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Sandia National Laboratories researchers have made the first measurements of thermoelectric behavior by a nanoporous metal-organic framework, a development that could lead to an entirely new class of materials for such applications as cooling computer chips and cameras and energy harvesting. The results were published in 'Thin Film Thermoelectric Metal-Organic Framework with High Seebeck Coefficient and Low Thermal Conductivity,' which appeared April 28 online in Advanced Materials.

Drought-induced tree mortality accelerating in forests

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

Researchers at Los Alamos National Laboratory have found that drought and heat-induced tree mortality is accelerating in many forest biomes as a consequence of a warming climate in their paper 'Darcy's law predicts widespread forest mortality under climate warming,' published in the journal Nature Climate Change.

Optical diagnostics researcher at Sandia wins DOE Early Career award

DOE/Sandia National Laboratories

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 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.

Starving cancer cells instead of feeding them poison

DOE/Sandia National Laboratories
Peer-Reviewed Publication

An enzyme-drug that prevents the essential nutrient asparagine from reaching cancer cells seem an effective way to kill them, but that enzyme-drug also does away with the nutrient glutamine that all cells need. Now a simulation has directed the mutation of the enzyme so that, in wet labs, it left normal cells unharmed in Petri dishes and cancer cells dead in test tubes. Lab tests are underway with mice. If successful, human tests are next.

Tests with Sandia's Davis gun aid B61-12 life extension effort

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories successfully completed a three-test series with its cannon-like Davis gun.

Phonons, arise!

DOE/Sandia National Laboratories
Peer-Reviewed Publication

The creation of devices to control phonons -- elusive atomic vibrations that transport heat energy in solids at speeds up to the speed of sound -- has taken a step forward when researchers successfully altered the thermal conductivity of a widely used commercial material, using only a simple nine-volt battery.
