Researchers at the Massachusetts Institute of Technology have developed a new way of revealing the presence of specific chemicals—whether toxins, disease markers, pathogens or explosives. The system visually signals the presence of a target chemical by emitting a fluorescent glow.
Researchers from North Carolina State University, Sandia National Laboratories, and the University of California, San Diego have developed new technology that uses microneedles to allow doctors to detect real-time chemical changes in the body—and to continuously do so for an extended period of time.
A transportation fuels expert from Sandia National Laboratories says policy makers should consider such practical issues as the number of gas stations selling ethanol and how long it takes to get new transportation technologies to market as they introduce aggressive federal and state energy policies.
Unexpected voltage increases of up to 25% in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents may need to make allowances for such surprise boosts.
Following on the news that the Japanese K computer topped other high-performance computers at the SC11 conference, the National Nuclear Security Administration’s IBM Blue Gene/Q prototype has topped the Graph500, an increasingly competitive ranking that stresses supercomputer performance on “big data” scaling problems rather than purely arithmetic computations.
With a muffled "pop," a flash of blue light, and a few ripples through 14,000 gallons of deionized water, Sandia National Laboratories' Annular Core Research Reactor (ACRR) recently conducted its 10,000th operation.
Light-emitting diodes (LEDs) are widely accepted as a more efficient and reliable option than tungsten incandescent bulbs. But recent research at Sandia National Laboratories shows that humans are as comfortable with white light generated by diode lasers, which are more efficient than LEDs at higher amperages.
Multiscale complexity is common across all combustion applications—internal combustion engines, rockets, and industrial boilers—and can range from tens of meters to billionths of meters. New techniques being employed at supercomputers covers this huge scale range using fewer computer hours, and could benefit efficiency levels in the combustion industry.
A dearth of public information, complicated marine environments, and even the corrosive effects of bubbles are among the challenges for companies trying to produce energy from river currents, tides, and waves, but Sandia National Laboratories is working on solutions. Sandia is helping companies on the frontier of the coming marine hydrokinetics industry navigate these and other concerns with support from the Department of Energy.
Two remarkable pulsed-power machines used to test the nation's defenses against atomic weapons have surpassed milestones at Sandia National Laboratories: 4,000 firings, called 'shots,' on the Saturn accelerator and 9,000 shots on the HERMES III accelerator.
Researchers at Sandia National Laboratories have designed and built a mobile research facility to trace and identify the origin of greenhouse gases. In addition to pinpointing the chemicals' location, the unique mobile facility can help researchers learn whether the gases are biogenic (coming from plant sources) or anthropogenic (coming from man-made sources).
Using iPad mobile devices, emergency preparedness officials and first responders can now, for the first time, make use of a new, science-based software tool developed at Sandia National Laboratories that allows them to view and modify accurate models of building damage and other post-event disaster effects.
Most Americans take electric power for granted, but for thousands of people living on tribal lands, getting to the grid can be a challenge. A lack of infrastructure, transmission capabilities, and policies impede the availability of electricity within the reservations and to outlying tribal areas. A program at Sandia National Laboratories addresses those challenges and is helping to train a new generation of Native American renewable energy advocates.
Researchers at Sandia National Laboratories have invented a technology that combines multiple radio frequency filters on a single chip, enabling the development of compact devices that efficiently access 3G and 4G networks.
The Ultra-high-voltage Silicon Carbide Thyristor, developed by GeneSiC Semiconductor Inc., and partners, can operate at up to 10 times higher voltage, four times higher blocking voltages, and 100 times faster switching frequency than silicon-based thyristors.
In a nod to Sandia National Laboratories' contributions to the field of robotics, the Smithsonian Institution has obtained nine of Sandia's historically significant robots for its permanent collection at the National Museum of American History.
Sandia National Laboratories' Battery Abuse Testing Laboratory is undergoing a major renovation so Sandia researchers can test larger batteries for electric and plug-in hybrid electric vehicles.
Sandia National Laboratories has developed a new technology with the potential to alter the air-cooling landscape in computing and microelectronics. Lab officials are now seeking licensees in the electronics chip cooling field to license and commercialize the device.
Testing techniques from Sandia National Laboratories are helping accelerate the growth of the nation's photovoltaic solar power industry through a partnership with TUV Rheinland PTL, LLC, a private testing and certification company in Tucson, Ariz.
A new thin-film coating process for manufacturing thermal batteries used in nuclear weapons and other munitions that was invented at Sandia National Laboratories will be industrialized under a new corporate partnership with a Maryland company. The process could lead to create lighter batteries in a variety of shapes for future applications.
Sandia National Laboratories and supercomputer manufacturer Cray Inc. are forming an institute focused on data-intensive supercomputers. The Supercomputing Institute for Learning and Knowledge Systems (SILKS), to be located at Sandia in Albuquerque, will take advantage of the strengths of Sandia and Cray by making software and hardware resources available to researchers who focus on a relatively new application of supercomputing.
Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli .
The National Nuclear Security Administration (NNSA) announced that researchers from Sandia and Los Alamos national laboratories have completed their second experiment in the past six months at Sandia's Z machine to explore the properties of plutonium materials under extreme pressures and temperatures.
A new hydrogen research initiative based in Japan will leverage Department of Energy (DOE)-funded hydrogen research at Sandia National Laboratories' California site and will likely become the first research effort to be rolled into a broader laboratory research umbrella aimed at increasing the laboratories’ hydrogen partnerships domestically and abroad.
A matchbook-sized atomic clock 100 times smaller than its commercial predecessors has been created by a team of researchers at Symmetricom Inc. Draper Laboratory and Sandia National Laboratories. The portable Chip Scale Atomic Clock (CSAC) also requires 100 times less power than its predecessors. Instead of 10 watts, it uses only 100 milliwatts.
