ALBUQUERQUE, N.M. — The atmospheric level of carbon dioxide — a gas that is great at trapping heat, contributing to climate change — is almost double what it was prior to the Industrial Revolution, yet it only constitutes 0.0415% of the air we breathe. This presents a challenge to researchers attempting to design artificial trees […]

LIVERMORE, Calif. — A team of Sandia National Laboratories researchers working on the reactor at the DIII-D National Fusion Facility is testing materials to make the next generation of fusion reactors, in the quest to develop more carbon-free energy sources. These magnetic confinement fusion reactors, called tokamaks, use magnetic fields to shape plasma into a […]
Most Promising Engineer of the Year honor goes to Sandia scientist
ALBUQUERQUE, N.M. — Sandia National Laboratories research and development manager Bishnu Khanal was recently honored with the Most Promising Asian American Engineer of the Year award for his work in next-generation optical lithography process development for numerous technologies, along with his deep-reaching community service. According to Asian American Engineer of the Year, Khanal was selected […]
Scientists chip away at a metallic mystery, one atom at a time
ALBUQUERQUE, N.M. — Gray and white flecks skitter erratically on a computer screen. A towering microscope looms over a landscape of electronic and optical equipment. Inside the microscope, high-energy, accelerated ions bombard a flake of platinum thinner than a hair on a mosquito’s back. Meanwhile, a team of scientists studies the seemingly chaotic display, searching […]
Seashell-inspired Sandia shield protects materials in hostile environments
ALBUQUERQUE, N.M. — Word of an extraordinarily inexpensive material, lightweight enough to protect satellites against debris in the cold of outer space, cohesive enough to strengthen the walls of pressurized vessels experiencing average conditions on Earth and yet heat-resistant enough at 1,500 degrees Celsius or 2,732 degrees Fahrenheit to shield instruments against flying debris, raises […]
Powerful Sandia machine-learning model shows diamond melting at high pressure
ALBUQUERQUE, N.M. — A Sandia National Laboratories supercomputer simulation model called SNAP that rapidly predicts the behavior of billions of interacting atoms has captured the melting of diamond when compressed by extreme pressures and temperatures. At several million atmospheres, the rigid carbon lattice of the hardest known substance on Earth is shown in SNAP (Spectral […]
Program in fusion energy attracted interns’ eyes
ALBUQUERQUE, N.M.— A bold plan paid off this past summer when Sandia National Laboratories staff members LaRico Treadwell and Khalid Hattar combined their passions for increasing inclusion of people of color with developing materials to eventually derive energy from nuclear fusion. Standing to benefit from the pilot project were three undergraduate interns from North Carolina […]
Remote high-voltage sensor unveiled at Sandia gamma ray lab
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 […]
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 […]
High-speed alloy creation might revolutionize hydrogen’s future
LIVERMORE, Calif. — A Sandia National Laboratories team of materials scientists and computer scientists, with some international collaborators, have spent more than a year creating 12 new alloys — and modeling hundreds more — that demonstrate how machine learning can help accelerate the future of hydrogen energy by making it easier to create hydrogen infrastructure […]
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 […]
