Using computer modeling, researchers from Sandia National Laboratories and the University of Illinois at Urbana-Champaign are helping to develop the means to prevent some deaths from infections caused by antibiotic resistant bacteria.
Sandia’s materials science team has engineered a platinum-gold alloy believed to be the most wear-resistant metal in the world. It’s 100 times more durable than high-strength steel, making it the first alloy, or combination of metals, in the same class as diamond and sapphire, nature’s most wear-resistant materials.
Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve detection sensitivity to chemicals in explosives or drugs.
From testing space shuttle tiles to making electricity from sunlight, the world’s first multimegawatt solar tower has contributed to energy research, space exploration, defense testing and solar energy commercialization since it was commissioned at Sandia National Laboratories in July 1978. The solar tower is a key component of a specific type of utility-scale solar energy technology that uses hundreds of large mirrors to reflect and concentrate sunlight onto a receiver on a tower. The heat from the concentrated sunlight is absorbed by either a liquid, gas or solid and stored or used immediately in a heat exchanger to generate electricity. This type of energy, called concentrating solar power, is appealing because it can supply renewable energy — even when the sun is not shining — without using batteries for storage. To mark the National Solar Thermal Test Facility’s 40th anniversary this month, present and past Sandia leaders and researchers, industry leaders and government represen
Sandia National Laboratories researchers have built a scaled test assembly that mimics a dry cask storage container for spent nuclear fuel to study how fuel temperatures change during storage and how the fuel’s peak temperatures affect the integrity of the metal cladding surrounding the spent fuel. Regulators could use the data to help verify computer simulations that show whether nuclear power utilities are complying with regulations that specify how much heat a dry cask can safely handle.
Researchers from Sandia National Laboratories have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power.
Sandia National Laboratories has worked with Structural Monitoring Systems for over 15 years to turn science fiction smart bridges that can send out warnings when they’re damaged into science fact.
Marine research could soon be possible without the risk of polluting either the air or the ocean. It’s thanks to a new ship design and feasibility study led by Sandia National Laboratories. Despite many advantages, the feasibility of a hydrogen-powered research vessel has never been studied or proven. Until now.
A multicolor laser pointer you can use to change the color of the laser with a button click — similar to a multicolor ballpoint pen — is one step closer to reality thanks to a new tiny synthetic material made at Sandia National Laboratories. Research on the new light-mixing metamaterial was published in Nature Communications earlier today.
Sandia National Laboratories is using its solar tower to help assess the impact of extreme temperature changes on materials.The tests, now in their second year, take advantage of the ability of Sandia’s National Solar Thermal Test Facility to simulate a very rapid increase in temperature followed by an equally rapid decrease. The testing is for the Air Force and will continue for at least another year.
In a year-long project, researchers at Sandia and Los Alamos national laboratories teamed up with the City of New Orleans to analyze ways to increase community resilience and improve the availability of critical lifeline services during and after severe weather. The team used historical hurricane scenarios to model how storms cause localized flooding, disrupt the electrical system and cut off parts of the community from lifeline services. Sandia researchers then developed a tool to analyze and identify existing clusters of businesses and community resources in areas less prone to inundation — such as gas stations, grocery stores and pharmacies that could be outfitted with microgrids to boost resilience.
Today with 3D printing you can make almost anything in a matter of hours. However, making sure that part works reliably takes weeks or even months. Until now.Sandia National Laboratories has designed and built a six-sided work cell, similar to a circular desk, with a commercial robot at its center that conducts high-throughput testing to quickly determine the performance and properties of the part.
Sandia National Laboratories materials scientist David Enos has been elected a fellow of NACE International, the chief professional society for corrosion engineering. He is the first Sandia employee to receive the honor.
Uniform powders produced at Sandia National Laboratories don’t just look nice, they outperform commercial varieties used to kick-start chemical reactions in solar cells and could be used to produce clean-burning hydrogen fuel. Their key ingredient: detergent.
Sandia National Laboratories will receive $10.5 million from the Department of Energy to research and design a cheaper and more efficient solar energy system.The work focuses on refining a specific type of utility-scale solar energy technology that uses mirrors to reflect and concentrate sunlight onto a receiver on a tower.
Jet fuel, pantyhose and plastic soda bottles are all products currently derived from petroleum. Sandia National Laboratories scientists have demonstrated a new technology based on bioengineered bacteria that makes it feasible to produce all three from renewable plant sources.
A long-standing collaboration between Sandia National Laboratories and Imagion Biosystems produced precise magnetic nanoparticles for a breast cancer clinical trial later this year. The nanoparticles stick to breast cancer cells, allowing the detection and removal of even small metastases.
Sandia National Laboratories won the Federal Laboratory Consortium for Technology Transfer’s national 2018 Technology Focus Award for the first wind turbine blades made from a 3-D printed mold. The labs also won FLC’s Excellence in Technology Transfer Award for advanced nanomaterial window films.
The Arctic is undergoing rapid change, with sea ice melting and temperatures rising at a faster pace than anywhere else in the world. Its changing environment affects global security, politics, the economy and the climate. Understanding these changes is crucial for shaping and safeguarding U.S. security in the future, Sandia scientists say. Sandia and the University of Alaska Fairbanks recently signed an umbrella Cooperative Research and Development Agreement to study these changes and partner on basic science, energy and security research in the Arctic.
Shared fates and experiences in a community can help it withstand changes to water availability due to climate change, a recent study by Sandia National Laboratories researchers found.The work, part of Sandia’s energy-water nexus program to help safeguard resilient and sustainable energy-water systems in the interest of national and global security, was recently published in a special socio-hydrology issue of Water Resources Research. The research paired a dynamic systems model of an acequia community and its water system with a hydrology model of an upland water source to study how the community responds to changes in water availability and flow.
