2-Feb-2015 The quest for efficiency in thermoelectric nanowires
Research detailed in a thermoelectric nanowire paper published by Sandia National Laboratories represents the first time researchers managed to control crystal orientation, crystal size and alloy uniformity by a single process. All three factors contribute to better thermoelectric performance.
29-May-2014 Get ready for the computers of the future
Sandia experts expect multiple computing device-level technologies in the future, rather than one dominant architecture. About a dozen possible next-generation candidates exist, including tunnel FETs (field effect transistors, in which the output current is controlled by a variable electric field), carbon nanotubes, superconductors and fundamentally new approaches, such as quantum computing and brain-inspired computing.
8-May-2014 Engineering better machines and buildings by understanding mechanics of materials
Sandia National Laboratories is working to fill gaps in the fundamental understanding of materials science through an ambitious long-term, multidisciplinary project called Predicting Performance Margins, or PPM. From the atomic level to full-scale components, the research links variability in materials' atomic configurations and microstructures with how actual parts perform.
15-Apr-2014 Wind tunnel tests support improved aerodynamic design of B61-12 bomb
Sandia National Laboratories has finished eight days of testing a full-scale mock unit representing the aerodynamic characteristics of the B61-12 gravity bomb in a wind tunnel.
The tests on the mock-up were done to establish the configuration that will deliver the necessary spin motion of the bomb during freefall and are an important milestone in the Life Extension Program to deliver a new version of the aging system, the B61-12.
19-Sep-2013 Study could help improve nuclear waste repositories
Sandia National Laboratories researchers are studying the movement of iodine-129 from spent nuclear fuel through a deep, clay-based geological repository.
Understanding that process is crucial as countries worldwide consider underground clay formations for nuclear waste disposal.
18-Jul-2013 Hurricane season: Predicting in advance what could happen
The Department of Homeland Security's National Infrastructure Simulation and Analysis Center, jointly housed at Sandia and Los Alamos national laboratories, studies how hurricanes and other disasters disrupt critical infrastructure, such as roads, electricity and water systems.
14-Jun-2013 Detecting homemade explosives, not toothpaste
Sandia National Laboratories researchers want airports, border checkpoints and others to detect homemade explosives made with hydrogen peroxide without nabbing people whose toothpaste happens to contain peroxide.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
