Sandia National Laboratories has developed key components of a software tool to help the Army's PEO GCS analyze countless what-if scenarios that can be manipulated as technology advances and the global environment, the federal budget, or other factors change. Sandia calls this advanced combination of modeling, simulation, and optimization decision support software the Capability Portfolio Analysis Tool (CPAT).
One of the most promising new kinds of battery to power electric cars is called a lithium-air battery. But progress has been slow. Researchers have used transmission electron microscope (TEM) imaging to observe, at a molecular level, what goes on during a reaction called oxygen evolution as lithium-air batteries charge; this reaction is thought to be a bottleneck limiting further improvements to these batteries.
A Sandia engineer who trained U.S. soldiers to avoid improvised explosive devices (IEDs) has developed a fertilizer that helps plants grow but can’t detonate a bomb. It’s an alternative to ammonium nitrate, an agricultural staple that is also the raw ingredient in most of the IEDs in Afghanistan. Sandia has decided not to patent or license the formula, but to make it freely available in hopes of saving lives.
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.
Technology used in downhole applications—such as geothermal or oil-well monitoring—must endure punishing conditions, from very high temperatures to tremendous pressures. Finding a solder material that can perform in these harsh environments is a constant challenge. Researchers have recently repurposed a solder alloy once intended defense applications that has all the right properties for well tasks.
Sandia National Laboratories researchers Lisa Deibler and Arthur Brown had a ready-made problem for their computer modeling work when they partnered with the National Nuclear Security Administration’s Kansas City Plant to improve stainless steel tubing that was too hard to meet nuclear weapon requirements.
Researchers have successfully measured reaction rates of a second Criegee intermediate, CH3CHOO, and proven that the reactivity of the atmospheric chemical depends strongly on which way the molecule is twisted. The measurements will provide further insight into hydrocarbon combustion and atmospheric chemistry.
Sandia National Laboratories is developing a suite of complementary technologies to help the emerging algae industry detect and quickly recover from algal pond crashes, an obstacle to large-scale algae cultivation for future biofuels. The research draws upon Sandia's longstanding expertise in microfluidics technology, its strong bioscience research program and significant internal investments.
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.
