Using a one-of-a-kind laser system at Los Alamos National Laboratory, scientists have created the largest neutron beam ever made by a short-pulse laser, breaking a world record. To create the neutron beam the scientists used the TRIDENT laser to focus high-intensity light on an ultrathin plastic sheet infused with an isotope of hydrogen called deuterium.
A team of nanomaterials researchers at Sandia National Laboratories has developed a new technique for radiation detection that could make radiation detection in cargo and baggage more effective and less costly for homeland security inspectors. Known as spectral shape discrimination, the method takes advantage of a new class of nanoporous materials known as metal-organic frameworks.
Supercomputing performance is getting a new measurement with the Graph500 executive committee's announcement of specifications for a more representative way to rate the large-scale data analytics at the heart of high-performance computing. An international team announced the single-source shortest-path specification to assess computing performance at the International Supercomputing Conference in Hamburg, Germany.
Paul Kotula recently told a colleague that Sandia National Laboratories' new aberration-corrected scanning transmission electron microscope (AC-STEM) was like a Lamborghini with James Bond features. The AC-STEM delivers electron beams accelerated at voltages from 80 kV to 200 kV, allowing researchers to study properties of structures at the nanoscale—crucial for materials scientists working on everything from microelectronics to nuclear weapons.
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.
