Deconstructing deleterious soot

February 7, 2019 • LIVERMORE, Calif. — In most situations, breaking things apart isn’t the best way to solve a problem. However, sometimes the opposite is true if you’re trying to characterize complex chemical compounds. That’s what Sandia National Laboratories scientists Nils Hansen a…

Modeling terrorist behavior with Sandia social-cultural assessments

January 24, 2019 • ALBUQUERQUE, N.M. — Part of what makes terrorists so frightening is their penchant for unpredictable, indiscriminate violence. One day they could attack a global financial center. And the next they could hit a neighborhood bike path. A team of Sandia social-behavioral scientists and computational modelers recently completed a two-year effort,...

January 22, 2019 • ALBUQUERQUE, N.M. — Retirement means different things to different people. To Mike Murphy it wasn’t about TV and golf, not after logging 40 years as an electrical engineer in the nuclear weapons program at Sandia National Laboratories. He wanted to put his experience to …

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,...
