Scientists chip away at a metallic mystery, one atom at a time
News Article, September 28, 2022 • 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...

Sodium-ion battery safety research: Advancing the next generation of energy storage technology
News Article, June 25, 2024 • Sandia National Laboratories’ Battery Abuse Testing Lab, the Department of Energy’s core facility for battery safety, is investigating the safety of sodium-ion battery technology. Due to sodium’s abundance and an electrochemistry that resembles lithium-ion batteries in some ways, sodium-ion batteries are being considered for grid storage and automotive applications. The...

Stunning discovery: Metals can heal themselves
News Article, August 8, 2023 • Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can be harnessed, it could usher in an engineering revolution — one in which self-healing engines, bridges and airplanes...

Using X-ray science to hit hydrogen storage targets
News Article, November 7, 2023 • Using soft X-ray techniques available through Berkeley Lab’s Advanced Light Source (ALS), a Sandia team including Mark Allendorf and Farid El Gabaly with collaborators from the Hydrogen Materials Advanced Research Consortium (HyMARC) are probing the chemistry of promising hydrogen storage materials to understand how they absorb and release hydrogen. The...

Video: Validating models for safety codes and standards
News Article, May 10, 2024 • Earlier this year, a test series at Sandia collected data to validate the models used for hydrogen safety codes and standards. Go behind the scenes with the research team who ran the test with partners from the National Renewable Energy Laboratory and support from US DOE Office of Energy Efficiency...
