ALBUQUERQUE, N.M. — Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages. Now, using a crystal smaller than a dime and a laser smaller than a shoebox, a Sandia National Laboratories team […]

‘I’m melting, melting’ — environmentally hazardous coal waste diminished by citric acid
ALBUQUERQUE, N.M. — In one of nature’s unexpected bounties, a harmless food-grade solvent has been used to extract highly sought rare-earth metals from coal ash, reducing the amount of ash without damaging the environment and at the same time increasing an important national resource. Coal ash is the unwanted but widely present residue of coal-fired […]
Sandia researcher awarded Early-Career Research Program grant
ALBUQUERQUE, N.M. — Working to solve a problem, supercomputing researchers may encounter incomplete data or flawed programs. For both issues, Sandia researcher Drew Kouri has attracted interest from the broad computing community for his ability to mitigate uncertainty in both supercomputer programs and data, optimizing each to reach the best solutions. His research was awarded […]
Look who’s turning 25
ALBUQUERQUE, N.M. — Sandia National Laboratories is celebrating 25 years of research conducted at its Z Pulsed Power Facility — a gymnasium-sized accelerator commonly referred to as Z or the Z machine. Due to COVID-19 restrictions, only a limited number of former leaders of the pulsed power program at Sandia will gather Friday to share […]
Setting gold and platinum standards where few have gone before
ALBUQUERQUE, N.M. — Like two superheroes finally joining forces, Sandia National Laboratories’ Z machine — generator of the world’s most powerful electrical pulses — and Lawrence Livermore National Laboratory’s National Ignition Facility — the planet’s most energetic laser source — in a series of 10 experiments have detailed the responses of gold and platinum at […]
Largest aerospace society names Sandia researcher ‘Engineer of the Year’
ALBUQUERQUE, NM — Humberto “Tito” Silva III, a Sandia National Laboratories researcher, has been named Engineer of the Year by the world’s largest aerospace technical society, the American Institute of Aeronautics and Astronautics. Selected by a committee of his peers, Silva was cited for improving failure-rate predictions of aerospace flight systems as they reenter Earth’s […]
Super-Earth atmospheres probed at Sandia’s Z machine
ALBUQUERQUE, N.M. — The huge forces generated by the Z machine at Sandia National Laboratories are being used to replicate the gravitational pressures on so-called “super-Earths” to determine which might maintain atmospheres that could support life. Astronomers believe that super-Earths — collections of rocks up to eight times larger than Earth — exist in the […]
Sandia nuclear physicist selected fellow of AAAS
ALBUQUERQUE, N.M. — Susan Seestrom, associate laboratories director for advanced science and technology and chief research officer at Sandia National Laboratories, has been named a fellow of the American Association for the Advancement of Science. The physicist was cited “for her pathbreaking work in nuclear physics, especially using ultra cold neutrons, and her leadership, both […]
Record neutron numbers at Sandia Labs’ Z machine fusion experiments
ALBUQUERQUE, N.M.— A relatively new method to control nuclear fusion that combines a massive jolt of electricity with strong magnetic fields and a powerful laser beam has achieved its own record output of neutrons — a key standard by which fusion efforts are judged — at Sandia National Laboratories’ Z pulsed power facility, the most […]
Machine-learning technique from Sandia Labs could improve fusion energy outputs
ALBUQUERQUE, N.M. — Machine-learning techniques, best known for teaching self-driving cars to stop at red lights, may soon help researchers around the world improve their control over the most complicated reaction known to science: nuclear fusion. Fusion reactions are typically hydrogen atoms heated to form a gaseous cloud called a plasma that releases energy as […]
50 million artificial neurons to facilitate machine-learning research at Sandia
ALBUQUERQUE, N.M. — Fifty million artificial neurons — a number roughly equivalent to the brain of a small mammal — were delivered from Portland, Oregon-based Intel Corp. to Sandia National Laboratories last month, said Sandia project leader Craig Vineyard. The neurons will be assembled to advance a relatively new kind of computing, called neuromorphic, based […]
Basic laws of physics spruce up machine learning
ALBUQUERQUE, N.M. — A proposed project to help scientists use the laws of physics to view multiscale physical events with a clarity never before achieved has won an Early Career Research Program award from the Department of Energy for Sandia National Laboratories researcher Nathaniel Trask. Such work may require observations over a millionfold change in […]
Sandia to receive Fujitsu ‘green’ processor
ALBUQUERQUE, N.M. — This spring, Sandia National Laboratories anticipates being one of the first Department of Energy laboratories to receive the newest A64FX Fujitsu processor, a Japanese Arm-based processor optimized for high-performance computing. Arm-based processors are used widely in small electronic devices like cell phones. More recently, Arm-based processors were installed in Sandia’s Astra supercomputer, […]
Sandia initiatives to protect US energy grid and nuclear weapons systems
ALBUQUERQUE, N.M. — To deter attempts to disable U.S. electrical utilities and to defend U.S. nuclear weapon systems from evolving technological threats, Sandia National Laboratories has begun two multiyear initiatives to strengthen U.S. responses. One is focused on defending large U.S. electrical utility systems from potential attacks by hostile nations, as well as from damage […]
Cooling unit saves half-million gallons of water at Sandia supercomputing center
ALBUQUERQUE, N.M. — A cooling unit installed on the roof of Sandia National Laboratories’ supercomputer center saved 554,000 gallons of water during its first six months of operation last year, says David J. Martinez, engineering project lead for Sandia’s Infrastructure Computing Services. The dramatic decrease in water use, important for a water-starved state, could be […]
