An international team of physicists at Los Alamos National Laboratory has succeeded in using intense laser light to accelerate protons to energies never before achieved.
LIVERMORE, Calif. -- The United States should create a high-level independent council to analyze and communicate critical issues to energy policymakers and the public, a group of 27 leaders in academia, government, and the private sector recommends in a new report.
RENO, Nev. -- Using one of the greatest sources of radiation energy created by man, University of Nevada, Reno researcher and faculty member Roberto Mancini is studying ultra-high temperature and non-equilibrium plasmas to mimic what happens to matter in accretion disks around black holes.
By substituting a single atom in a molecule widely used to purify water, researchers at Sandia National Laboratories have created a far more effective decontaminant with a shelf life superior to products currently on the market.
They've been dubbed "grassoline" -- second generation biofuels made from inedible plant material, including fast-growing weeds, agricultural waste, sawdust, etc. -- and numerous scientific studies have shown them to be prime candidates for replacing gasoline to meet our transportation needs.
PHILADELPHIA ?- Engineers from the University of Pennsylvania, Sandia National Laboratories and Rice University have demonstrated the formation of interconnected carbon nanostructures on graphene substrate in a simple assembly process that involves heating few-layer graphene sheets to sublimation using electric current that may eventually lead to a new paradigm for building integrated carbon-ba
An engineered metamaterial proved it can function as a state-of-the-art device in the complex terahertz range of the electromagnetic spectrum, setting a standard of performance for modulating tiny waves of radiation, according to a team of researchers from Boston College, the Los Alamos and Sandia national laboratories, and Boston University.
An in-depth study by Sandia National Laboratories and General Motors Corp. has found that plant and forestry waste and dedicated energy crops could sustainably replace nearly a third of gasoline use by the year 2030.
An eclectic group of artists and scientists that organizers have dubbed the ''dream team'' of imaging and visualization are gathered at New York University this week to begin to create a photographic system capable of capturing and displaying a gigapixel -- one billion pixels -- of visual information in a single image.
A new class of very small handheld devices can detect motion a thousand times more subtly than any tool known. "There was nothing in the [optics] literature to predict that this would happen," says Sandia National Laboratories researcher Dustin Carr of his group's device, which reflects a bright light from a very small moving object. Sandia is a National Nuclear Security Administration laboratory.
A radar, originally developed by the National Nuclear Security Administration's Sandia National Laboratories for military surveillance and reconnaissance applications, is helping a volunteer search and rescue group save lives. Rapid Terrain Visualization (RTV) precision-mapping synthetic aperture radar (SAR) data was used for the first time last November by the Albuquerque Mountain Rescue Council (AMRC) to help find and rescue a hiker stranded in the dark in the Sandia Mountains in New Mexico.
University of California scientists working at Los Alamos National Laboratory with a colleague from Sandia National Laboratories have developed a new method for exciting light emission from nanocrystal quantum dots. The discovery provides a way to supply energy to quantum dots without wires, and paves the way for a potentially wider use of tunable nanocrystalline materials in a variety of novel light-emitting technologies ranging from electronic displays to solid-state lighting and electrically pumped nanoscale lasers.
A device to help eliminate friendly fire during military combat has been created by engineers at the National Nuclear Security Administration's Sandia National Laboratories. Building on more than 10 years of research and development, Sandia engineers have created a radar tag sensor that is mounted on military vehicles and is recognizable to an attack aircraft as a "friendly." The device, tracked via aircraft radar, can be used to identify both U.S. and coalition forces during combat to avoid fratricide. During war, fratricide is the act of killing one's own soldiers.
You can't get something for nothing, physicists say, but sometimes a radical innovation can come close. Researchers at Sandia National Laboratories -- exceeding the predictions of a 100-year-old law of physics -- have shown that filaments fabricated of tungsten lattices emit remarkably more energy than solid tungsten filaments in certain bands of near-infrared wavelengths when heated. This greater useful output offers the possibility of a superior energy source to supercharge hybrid electric cars, electric equipment on boats, and industrial waste-heat-driven electrical generators. The lattices' energy emissions put more energy into wavelengths used by photovoltaic cells that change light into electricity to run engines.
In an operating room in Carle Hospital in Urbana, Ill., on May 7, as scientists from the University of Illinois (UI) and Sandia National Laboratories watched, surgeon Michael Goldwasser fitted a highly unusual ceramic prosthetic device into the mouth of an elderly woman who had lost most of her teeth and along with it, much of the bone of her lower jaw.
