Sandia National Laboratories has developed a unique materials approach to multilayered, ceramic-based, 3D microelectronics circuits, such as those used in cell phones. The approach compensates for how changes due to temperature fluctuations affect something called the temperature coefficient of resonant frequency, a critical property of materials used in radio and microwave frequency applications.
A Sandia National Laboratories technology has been used to remove radioactive material from more than 43 million gallons of contaminated wastewater at Japan's damaged Fukushima Daiichi nuclear power plant. Sandia researchers had worked around the clock following the March 2011 disaster to show the technology worked in seawater, which was pumped in to cool the plant's towers.
A Sandia National Laboratories modeling study contradicts a long-held belief of geologists that pore sizes and chemical compositions are uniform throughout a given strata, which are horizontal slices of sedimentary rock. By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from underground oil reservoirs and water aquifers.
Navy pilots and other flight specialists soon will have a new "smart machine" installed in training simulators that learns from expert instructors to more efficiently train their students. Sandia National Laboratories' AEMASE is being provided to the Navy as a component of flight simulators.
Sandia National Laboratories and the U.S. Department of Energy have released a new tool to help utilities, developers, and regulators identify the energy storage options that best meet their needs. Partnering with DNV KEMA, Sandia is releasing Energy Storage Select, or ES-Select, software under a public license to the company.
An air sampler the size of an ear plug is expected to cheaply and easily collect atmospheric samples to improve computer climate models. The novel design of Sandia National Laboratories' phase-change micro-valve sensor employs a commonly used alloy to house an inexpensive microvalve situated above the sample chamber.
Sandia National Laboratories is using its Ion Beam Laboratory to study how to rapidly evaluate the tougher advanced materials needed to build the next generation of nuclear reactors and extend the lives of current reactors.
It turns out you can be too thin—especially if you're a nanoscale battery. A team of researchers built a series of nanowire batteries to demonstrate that the thickness of the electrolyte layer can dramatically affect the performance of the battery, effectively setting a lower limit to the size of the tiny power sources.
High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories. The simulations show the release of output energy that was many times greater than the energy fed into the container's liner.
Nearly two-thirds of the oil we use comes from wells drilled using polycrystalline diamond compact (PDC) bits, originally developed nearly 30 years ago to lower the cost of geothermal drilling. Sandia National Laboratories and the U.S. Navy recently brought the technology fullcircle, showing how geothermal drillers might use the original PDC technology, incorporating decades of subsequent improvements by the oil and gas industry.
In a challenge to current astrophysical models, researchers at Sandia National Laboratories and the University of Rostock in Germany have found that current calibrations of planetary interiors overstate water's compressibility by as much as 30%.
In mid-December 2011, Lawrence Livermore National Laboratory received a call from the Air Force Joint Space Operations Center (JSpOC). At the time, laboratory scientists were working with JSpOC to upgrade their command and control software. But this call was about something very different.
Sandia National Laboratories has developed an experimental smart outlet that autonomously measures, monitors, and controls electrical loads with no connection to a centralized computer or system. The goal of the smart outlet and similar innovations is to make the power grid more distributed and intelligent, capable of reconfiguring itself as conditions change.
Sandia National Laboratories researchers, using off-the-shelf equipment in a chemistry laboratory, have been working on ways to improve amputees' control over prosthetics with direct help from their own nervous systems.
Sandia National Laboratories researchers have developed a new family of liquid salt electrolytes, known as MetILs, that could lead to batteries able to cost-effectively store three times more energy than today's batteries. The research might lead to devices that can help economically and reliably incorporate large-scale intermittent renewable energy source into the nation's electric grid.
Sandia National Laboratories' decontamination foam, developed more than a decade ago and used to decontaminate federal office buildings and mailrooms during the 2001 anthrax attacks, is now being used to decontaminate illegal methamphetamine laboratories. The foam renders all types of typical chemical and biological agents harmless.
Consistent appraisals of homes and businesses outfitted with photovoltaic installations are a real challenge for the nation’s real estate industry, but a new tool developed by Sandia National Laboratories and Solar Power Electric and licensed by Sandia addresses that issue.
Take two Sandia National Laboratories engineers who are hunters, get them talking about the sport and it shouldn't be surprising when the conversation leads to a patented design for a self-guided bullet that could help war fighters. A Sandia team has invented a dart-like, self-guided bullet for small-caliber, smooth-bore firearms that could hit laser-designated targets at distances of about 2,000 m.
By using a novel technique to better understand mineral growth and dissolution, researchers at Oak Ridge National Laboratory are improving predictions of mineral reactions and laying the groundwork for applications ranging from keeping oil pipes clear to sequestering radium.
Sometimes total electrical isolation is a good thing—and that's the idea behind a power-over-fiber communications cable being developed by engineers at Sandia National Laboratories. The Sandia team is developing a hybrid cable design that uses fiber to send and regulate optical power to the communications electronics integral to the cable. A patent is pending on the design.
Addressing the complexity of Domain Name System Security (DNSSEC), Sandia National Laboratories computer scientist Casey Deccio has developed a new visualization tool known as DNSViz. DNSSEC is a standard security feature at high-level government offices, but it is extremely complex and Deccio’s tool helps simplify implementation.
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.
