Thwarting oil-pipeline corrosion by identifying a nanoscale villain

June 6, 2019 • ALBUQUERQUE, N.M. — Steel pipes rust and eventually fail. To preempt disasters, oil companies and others have created computer models to predict when replacement is needed. But if the models themselves go wrong, they can be modified only through experience, a costly problem if detection comes too late. Now, researchers...

Quantum computing steps further ahead with new projects at Sandia

January 7, 2019 • ALBUQUERQUE, N.M. — Quantum computing is a term that periodically flashes across the media sky like heat lightning in the desert: brilliant, attention-getting and then vanishing from the public’s mind with no apparent aftereffects. Yet a multimillion dollar international effort to build quantum computers is hardly going away. And now,...

‘Impactful Times’ tells story of decades of Sandia shock physics research

October 17, 2017 • ALBUQUERQUE, N.M. — Mark Boslough and Dave Crawford of Sandia National Laboratories predicted the Hubble telescope could see a rising plume as comet Shoemaker-Levy 9 crashed into Jupiter in 1994. Their prediction, however, went against the prevailing thought that the impac…

Black hole models contradicted by hands-on tests at Sandia’s Z machine

August 28, 2017 • ALBUQUERQUE, N.M. — A long-standing but unproven assumption about the X-ray spectra of black holes in space has been contradicted by hands-on experiments performed at Sandia National Laboratories’ Z machine. Z, the most energetic laboratory X-ray source on Earth, can duplicate the X-rays surrounding black holes that otherwise can be watched only from a...
