4-Mar-2016 New ways of looking at glass-to-metal seals
Components housed in stainless steel for protection against extreme environments require paths for electricity to power them and communicate with them. Those paths in turn need a reliable insulation seal, so strong bonds between materials for airtight seals are crucial.
26-Jan-2016 Got Solitons? Researcher sees problem as a solution
Sandia National Laboratories' Juan Elizondo-Decanini turned a long-standing problem into an idea he believes could lead to better and less expensive machines, from cell phones to pressure sensors.
15-Oct-2015 W80-4: Sandia California works on nuclear weapon Life Extension Program
Sandia National Laboratories is performing a Life Extension Program on the W80-4 nuclear weapon. The Life Extension Program is refurbishing the W80 warhead with replacement components for aging technology and components that have limited lifespans. Much of the work is being done at Sandia's California site.
23-Sep-2015 Techniques could create better material, design in high-consequence uses
Sandia National Laboratories is studying additive manufacturing and its potential for high-consequence applications. Two aspects of that effort are to understand both the properties of newly formed materials and how to design to get just what's needed without over-designing.
22-Jul-2015 Whole lotta shakin' goin' on
It took decades for technology to catch up with the math David Smallwood worked out to control vibration table shakers. Smallwood, a retired Sandia National Laboratories researcher who consults at the labs, knew that shaking in all directions at once was the key to realistic parts testing. Now Sandia is putting the algorithms he developed more than 30 years ago to the test.
18-May-2015 Optical diagnostics researcher at Sandia wins DOE Early Career award
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.
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.
15-Jan-2013 Sandia airborne pods seek to trace nuclear bomb's origins
If a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for analysis.
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.
