Researchers at Sandia National Laboratories are developing a medical instrument that will be able to quickly detect a suite of biothreat agents, including anthrax, ricin, botulinum, shiga, and SEB toxin. The device, once developed, approved by the U.S. Food and Drug Administration, and commercialized, would most likely be used in emergency rooms in the event of a bioterrorism incident.
Trapped atomic ions are a promising architecture that satisfies many of the critical requirements for constructing a quantum computer. Scientists who hope to push the capabilities of ion traps even further using cryogenics have recently published a report in Science that speculates on ion trap technology as a scalable option for quantum information processing.
Sandia National Laboratories has become a pioneer in large-scale passive optical networks, building the largest fiber optical local area network in the world. The network pulls together 265 buildings and 13,000 computer network ports and brings high-speed communication to some of the laboratories' most remote technical areas for the first time.
Researchers at Rice University and Sandia National Laboratories have made a nanotube-based photodetector that gathers light in and beyond visible wavelengths. It promises to make possible a unique set of optoelectronic devices, solar cells, and perhaps even specialized cameras.
Sandia National Laboratories has completed $199 million in facilities construction and repair as part of an 11-year national effort to revitalize the physical infrastructure of nuclear security enterprise sites.
In a public-private partnership that takes full advantage of the Livermore Valley Open Campus for the first time, Sandia National Laboratories and Cool Earth Solar have signed an agreement that could make solar energy more affordable and accessible. The five-year Cooperative Research & Development Agreement calls for researchers with Sandia's New Mexico solar energy program to help pilot, characterize, and validate Cool Earth Solar's inflated, concentrated photovoltaic technology.
Sandia National Laboratories has issued three information technology (IT) contracts totaling $353 million over a potential term of seven years. The awards streamline IT contracting at the laboratories.
“Zombie” mammalian cells that may function better after they die have been created by researchers at Sandia National Laboratories and the University of New Mexico (UNM). The simple technique coats a cell with a silica solution to form a near-perfect replica of its structure. The process may simplify a wide variety of commercial fabrication processes from the nano- to macroscale.
If a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for analysis. Relatively inexpensive UAVs—equipped with radiation sensors and specialized debris-samplers—could fly right down the throat of telltale radiation over a broad range of altitudes without exposing a human crew to hazards. A Sandia National Laboratories-developed airborne particulate-collection system demonstrated those kinds of capabilities.
Sandia National Laboratories Truman Fellow Anne Ruffing has engineered two strains of cyanobacteria to produce free fatty acids, a precursor to liquid fuels, but she has also found that the process cuts the bacteria’s production potential.
One of the National Security Administration's three national laboratories is building regional testing centers around the U.S. to field-test hardware for solar companies before their multimillion-dollar solar systems are installed in buildings.
Sandia National Laboratories has launched a Sustainability Innovation Foundry that combines laboratories-wide resource conservation with efforts to turn research in fields related to sustainability into business opportunities. Sandia is on track to meet an ambitious goal of cutting energy intensity in buildings 30% by 2015, using a 2005 baseline, and it hopes that what it has learned as part of this effort will carry over into general industry practices.
Tunnels are often used to smuggle people and illicit goods between the border of the U.S. and Mexico. Researchers have attempted to use seismic waves to find these shallow tunnels, but current methods often miss them because of what is called the “halo effect”, in which fracturing and other geological anomalies create diffuse boundaries that hide open areas. A two-year study has shed light on this phenomenon and may lead to better results.
Sandia National Laboratories' multiphase shock tube began with a hallway conversation that led to what engineer Justin Wagner describes as the only shock tube in the world that can look a how shock waves interact with dense particle fields. The machine is considered multiphase because it can study shock wave propagation through a mixture of gas and solid particles.
Researchers at Sandia National Laboratories and the University of New Mexico are comparing supercomputer simulations of blast waves on the brain with clinical studies of veterans suffering from mild traumatic brain injuries (TBIs) to help improve helmet designs.
Sandia National Laboratories has signed a pair of cooperative research and development agreements (CRADAs) that could broadly add to the Labs' research into combustion, defense, energy, and nuclear security. The umbrella CRADAs, which enable Sandia and its partners to pursue multiple projects in a variety of categories, are with Northrop Grumman Information Systems and General Electric Global Research.
The explosive PETN has been around for a century and is used by everyone from miners to the military, but it took new research by Sandia National Laboratories to begin to discover key mechanisms behind what causes it to fail at small scales. By developing a novel technique based on physical vapor deposition to create samples with varying thickness, the researchers were able to study detonation behavior at the sub-millimeter scale and to determine that PETN detonation fails at a thickness roughly the width of human hair.
Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests, according to a Sandia National Laboratories research paper accepted for publication by Physical Review Letters .
Researchers at Lawrence Berkeley National Laboratory's Molecular Foundry developed a first-of-its-kind model for providing a comprehensive description of the way in which molecular bonds form and rupture. This model enables researchers to predict the "binding free energy" of a given molecular system, a key to predicting how that molecule will interact with other molecules.
Sandia National Laboratories has developed a cost-effective robotic hand that can be used in disarming improvised explosive devices, or IEDs. The Sandia Hand addresses challenges that have prevented widespread adoption of other robotic hands, such as cost, durability, dexterity, and modularity.
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.
In 2010, Sandia National Laboratories researcher Jeff Tsao and Harry Saunders of The Breakthrough Institute in Oakland, Calif., predicted that light-emitting diodes would have a similar improvement in productivity—but not less energy use—that occurred upon the introduction of the Edison light bulb. Now, they have reprised their report to emphasize conclusions they say were misinterpreted by the media.
The economics of offshore windpower are different from land-based turbines, due to installation and operational challenges. Vertical axis wind turbines could offer the best solution thanks to several factors, including a lower center of gravity and a bottom-mounted drivetrain. But Sandia National Laboratories engineers are looking how to scale up product of the turbines’ curved blades, which are difficult to manufacture.
Researchers at Sandia National Laboratories have developed a lab-on-a-disk platform, SpinDx, that they believe will be faster, less expensive, and more versatile than current medical diagnostic tools.
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.
