More small, clean-energy businesses will tap into Sandia technical expertise

ALBUQUERQUE, N.M. — The Department of Energy has chosen five more small, clean-energy businesses to work with Sandia National Laboratories to speed the commercialization of next-generation technologies and gain a global competitive advantage for the U.S. “Sandia is excited to bring these small businesses together with our scientists and engineers to tackle challenges and bring […]

Better living through pressure: functional nanomaterials made easy

ALBUQUERQUE, N.M. — Using pressure instead of chemicals, a Sandia National Laboratories team has fabricated nanoparticles into nanowire-array structures similar to those that underlie the surfaces of touch-screens for sensors, computers, phones and TVs. The pressure-based fabrication process takes nanoseconds. Chemistry-based industrial techniques take hours. The process, called stress-induced fabrication, “is a new technology that […]

Drop of mock B61-12 is first of new flight tests

ALBUQUERQUE, N.M. — From a distance, the drop of a mock nuclear weapon — containing only non-nuclear components — was a mere puff of dust rising from a dry lake bed at Nevada’s Tonopah Test Range. However, it marked the start of a new series of test flights vital to the nation’s B61-12 weapon refurbishment […]

Predicting the limits of friction: Sandia looks at properties of material

ALBUQUERQUE, N.M. — Normally, bare metal sliding against bare metal is not a good thing. Friction will destroy pistons in an engine, for example, without lubrication. Sometimes, however, functions require metal on metal contact, such as in headphone jacks or electrical systems in wind turbines. Still, friction causes wear and wear destroys performance, and it’s […]

Testing for Zika virus: there’s an app for that

Sandia prototype dramatically cuts cost, time for detection of mosquito-borne illness LIVERMORE, Calif. — Add rapid, mobile testing for Zika and other viruses to the list of things that smartphone technology is making possible. Researchers at Sandia National Laboratories have developed a smartphone-controlled, battery-operated diagnostic device that weighs under a pound, costs as little as […]

Power partners: Sandia draws industry into quest for cheaper, cleaner electricity

ALBUQUERQUE, N.M. — Sandia National Laboratories is working with three industry partners to commercialize a distributed power system that can produce cheaper, cleaner, more efficient electricity. The labs signed three-year Cooperative Research and Development Agreements with Peregrine Turbine Technologies of Wiscasset, Maine; Xdot Engineering and Analysis of Charlottesville, Virginia; and Flowserve Corp. of Irving, Texas. […]

Guiding Light: Sandia creates 3-D metasurfaces with optical possibilities

ALBUQUERQUE, N.M. — Metamaterials don’t exist in nature, but their ability to make ultra-thin lenses and ultra-efficient cell phone antennas, bend light to keep satellites cooler and let photovoltaics absorb more energy mean they offer a world of possibilities. Formed by nanostructures that act as “atoms,” arranged on a substrate to alter light’s path in […]

Big changes from a small package for hydrogen storage

Sandia researchers use confined nanoparticles to improve hydrogen storage materials performance LIVERMORE, Calif. — Sometimes, you have to go small to win big. That is the approach a multilab, interdisciplinary team took in using nanoparticles and a novel nanoconfinement system to develop a method to change hydrogen storage properties. This discovery could enable the creation […]

Sandia intern, mentor win chemical society award

ALBUQUERQUE, N.M. —Sandia National Laboratories student intern Julian A. Vigil and researcher Timothy N. Lambert captured a 2017 American Chemical Society (ACS) Division of Inorganic Chemistry Award for Undergraduate Research. Vigil will receive a financial stipend and a plaque; his mentor Lambert will receive a plaque for permanent display at Sandia. Vigil’s research career began as […]

Sandia using kinetics, not temperature, to make ceramic coatings

Room temperature coatings make design, fabrication flexible ALBUQUERQUE, N.M. — Researcher Pylin Sarobol explains an elegant process for ultrafine-grained ceramic coatings in a somewhat inelegant way: sub-micron particles splatting onto a surface. That splatting action is a key part of a Sandia National Laboratories project to lay down ceramic coatings kinetically. By making high-velocity submicron […]
