Three National Nuclear Security Administration (NNSA) sites where The Babcock & Wilcox Co. (B&W) operates have been selected as recipients of R&D Magazine's 2013 R&D 100 Awards. Sites honored include the Y-12 National Security Complex, Lawrence Livermore National Laboratory, and Los Alamos National Laboratory.
Three technologies from the U.S. Dept. of Energy’s Los Alamos National Laboratory and its partners were honored with 2013 R&D 100 Awards. MiniMAX is a battery-powered, digital x-ray imaging system that is completely self-contained, lightweight, compact and portable. KiloPower uses a nuclear fission system as a heat source that transfers heat via a heat pipe to a small power convertor to produce electricity from uranium.
Los Alamos National Laboratory (LANL) and Tribogenics, a developer of x-ray solutions, have recently partnered to create a unique, lightweight, compact, low-cost X-ray system that uses LANL’s MiniMAX (miniature, mobile, agile, x-ray) camera to provide real-time inspection of sealed containers and facilities. The innovative technology will be featured at an upcoming International Atomic Energy Agency conference.
Improved methods for breaking down cellulose nanofibers are central to cost-effective biofuel production and the subject of new research from Los Alamos National Laboratory and the Great Lakes Bioenergy Research Center. Scientists are investigating the unique properties of crystalline cellulose nanofibers to develop novel chemical pretreatments and designer enzymes for biofuel production from cellulosic—or non-food—plant derived biomass.
New ultrathin, planar, lightweight and broadband polarimetric photonic devices and optics could result from recent research by a team of Los Alamos National Laboratory scientists. The advances would boost security screening systems, infrared thermal cameras, energy harvesting and radar systems.
Los Alamos National Laboratory scientists have designed a new type of nanostructured-carbon-based catalyst that could pave the way for reliable, economical next-generation batteries and alkaline fuel cells, providing for practical use of wind- and solar-powered electricity, as well as enhanced hybrid electric vehicles.
The National Nuclear Security Administration announced that its Sequoia supercomputer at Lawrence Livermore National Laboratory has completed its transition to classified computing in support of the Stockpile Stewardship Program, which helps the United States ensure the safety, security, and effectiveness of its aging nuclear weapons stockpile without the use of underground testing.
Observing the evolution of a particular type of antibody in an infected HIV-1 patient has provided insights that will enable vaccination strategies that mimic the actual antibody development within the body. Spearheaded by Duke University, the multi-institution study included analysis from Los Alamos National Laboratory and used high-energy X-rays from the Advanced Photon Source at Argonne National Laboratory.
A new study by a team of scientists defines previously unknown properties of transmitted HIV-1, the virus that causes AIDS. The viruses that successfully pass from a chronically infected person to a new individual are both remarkably resistant to a powerful initial human immune-response mechanism, and they are blanketed in a greater amount of envelope protein that helps them access and enter host cells.
Still among the 25 fastest supercomputers in the world, the $121 million Roadrunner at Los Alamos National Laboratory was decommissioned Sunday. Roadrunner, constructed with the help of IBM, was the first to break the petaflop barrier in 2008, and was unusual at the time for being entirely built out of commercially available parts. Its replacement is smaller, cheaper, and faster.
Recently, a Los Alamos National Laboratory quantum cryptography (QC) team successfully completed the first-ever demonstration of securing control data for electric grids using quantum cryptography. The project, says experts, shows that quantum cryptography is compatible with electric-grid control communications, providing strong security assurances rooted in the laws of physics, without introducing excessive delays in data delivery.
Wireless communications and optical computing could soon get a significant boost in speed, thanks to “slow light” and specialized metamaterials through which it travels. Researchers have made the first demonstration of rapidly switching on and off “slow light” in specially designed materials at room temperature. This work opens the possibility to design novel, chip-scale, ultrafast devices for applications in terahertz wireless communications and all-optical computing.
Scientists made a major step forward recently towards transforming biomass-derived molecules into fuels. The team led by Los Alamos National Laboratory researchers elucidated the chemical mechanism of the critical steps, which can be performed under relatively mild, energy-efficient conditions.
A team of researchers have built a new type of nuclear reactor that is reliable enough to be used on space flights. The prototype, which has been used to generate 24 W of electricity, relies on heat pipe technology developed at Los Alamos National Laboratory in 1983. The fluid-based cooling system requires no moving parts and the reactor itself is based on a simply closed-loop Stirling engine.
Scientists at Los Alamos National Laboratory have observed, for the first time, how a laser penetrates dense, electron-rich plasma to generate ions. The process has applications for developing next generation particle accelerators and new cancer treatments.
Members of the Mars Science Laboratory Curiosity rover ChemCam team have received the first photos from the instrument's remote microimager. The successful capture of ChemCam's first 10 photos sets the stage for the first test bursts of the instrument's rock-zapping laser in the near future.
A team of researchers studying the fundamental properties of the actinide elements has significantly advanced the understanding of the electronic structure of elements that have electrons occupying f-orbitals.
Two Los Alamos National Laboratory scientists are among the team recently funded to explore ways to create the precise immune factors needed for effective vaccines against HIV. The Duke University-led consortium will largely concentrate on inducing broadly neutralizing antibodies that can prevent HIV-1 infection, as well as on generating protective T-cell and innate immune system responses.
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 Princeton University-led team of scientists has shown how electrons moving in certain solids can behave as though they are a thousand times more massive than free electrons, yet at the same time act as speedy superconductors.
Lawrence Livermore National Laboratory researchers have for the first time identified a precise measurement of the amount of radiation damage that will occur in any given material. With a full understanding of the early stages of the radiation damage process, researchers are provided with better knowledge and tools to manipulate materials to our advantage.
