Sandia Labs wins seven R&D 100 Awards and two specialty honors

ALBUQUERQUE, N.M. — Competing in an international pool of universities, corporations and government labs, inventions from Sandia National Laboratories captured seven R&D 100 Awards (one in conjunction with the National Renewable Energy Laboratory) this year, as well as two special awards for green technology and corporate responsibility. Independent panels of judges selected projects to represent […]

Simulating sneezes and coughs to show how COVID-19 spreads

ALBUQUERQUE, N.M. — Two groups of researchers at Sandia National Laboratories have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions. Both teams used Sandia’s decades of experience with advanced computer simulations studying how liquids and gases move for its nuclear stockpile stewardship […]

Tread tester

ALBUQUERQUE, N.M. — Simulating how a tire’s tread, rubber and size respond to a road’s corners, angles and hills, Sandia National Laboratories and The Goodyear Tire & Rubber Co. have developed a virtual means of showing a tire’s performance before the first prototypes are ever built. Computer simulations test a virtual tire on a virtual […]

A splash of detergent makes catalytic compounds more powerful

ALBUQUERQUE, N.M — Researcher David Rosenberg examines images of a white powder under a powerful scanning electron microscope. Up close, the powder looks like coarse gravel, a heap of similar but irregular chunks. Then he looks at a second image — the same material produced by colleague Hongyou Fan instead of purchased from a catalog […]

Digital in-line holography helps researchers ‘see’ into fiery fuels

ALBUQUERQUE, N.M. — Transportation accidents, such as trucks crashing on a highway or rockets failing on a launch pad, can create catastrophic fires. It’s important to understand how burning droplets of fuel are generated and behave in those extreme cases, so Sandia National Laboratories researchers have developed 3-D measurement techniques based on digital in-line holography. […]

Survivor: Sandia ensures US nuclear weapons deterrent can remain effective, credible

ALBUQUERQUE, N.M. — It may sound strange to say that nuclear weapons must survive radiation. But as part of its mission of ensuring the nation’s stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they’re hit by radiation, especially a type called fast neutrons.
