In the spirit of continued collaboration, a UC Early…
LLNL researchers uncover culprits behind pitting corrosion in 3D-printed stainless steel
Like a hidden enemy, pitting corrosion attacks metal surfaces, making it difficult to detect and control. This type of corrosion, primarily caused by prolonged contact with seawater in nature, is especially problematic for naval vessels. In a recent paper published in Nature Communications, Lawrence Livermore National Laboratory (LLNL) scientists delved into the mysterious…

Engineers and chemists at Lawrence Livermore National Laboratory (LLNL) and Meta have developed a new kind of 3D-printed material capable of replicating characteristics of biological tissue, an advancement that could impact the future of “augmented humanity.” In a paper recently published in the journal Matter, LLNL and Meta researchers describe a framework for creating a …
New film captures LLNL engineer-turned-astronaut’s inspiring journey
It was a chilly December night in 1972. Under a tawny half-moon hovering over California’s Central Valley, an impressionable 10-year-old boy named José Hernández looked skyward and saw his future. Hernández had spent that evening with his family as they gathered around their black-and-white television. Young José, a fan of "Star Trek," performed his usual duties as his…
Lab’s newest machinists celebrate graduation from vaunted apprenticeship program
Lawrence Livermore National Laboratory Engineering leadership recently congratulated the latest graduates from the Machinist Apprenticeship Program at a ceremony marking their completion of the program and transition to state-certified machinists. During the ceremony, held at the traditional Cattlemen’s Steakhouse in Livermore, Lab leaders, current and former apprentices…
LLNL introduces Advanced Characterization and Evaluation Laboratory and manufacturing facility
Lawrence Livermore National Laboratory (LLNL) and directorate leadership held dual ribbon-cutting ceremonies on May 24, officially marking the opening of the Lab’s Advanced Characterization and Evaluation Laboratory (ACEL) and newest advanced manufacturing facility. The ACEL will serve LLNL’s Nondestructive Evaluation (NDE) group and the Nondestructive Characterization…
Girls Who Code ‘Altamont Connection’ brings students from Livermore and Tracy to the Lab
High school students from Livermore and Tracy visited Lawrence Livermore National Laboratory (LLNL) on May 5 for a first-of-its kind event bringing the two cities’ Girls Who Code (GWC) programs and others together on-site for group activities and tours under a new “Altamont Connection” moniker. The event, which included tours of the National Ignition Facility, Discovery…
Lab engineer shares in DOE project award for work on the Vera C. Rubin Observatory
A Lawrence Livermore National Laboratory (LLNL) engineer and the SLAC National Accelerator Laboratory are among those sharing a Department of Energy (DOE) award for their roles in building the world’s newest observatory. The DOE honor, the 2021 project management achievement award, was recently presented for work done on the Legacy Survey of Space and Time camera (LSSTCam)…
LLNL’s Kamath honored as 2023 SIAM fellow
The Society for Industrial and Applied Mathematics (SIAM), the world’s premier professional organization for applied mathematicians and computational scientists, has selected Lawrence Livermore National Laboratory research staff member Chandrika Kamath as a member of the SIAM fellows class of 2023. The prestigious fellow designation is a lifetime honorific title and honors…
Computational Engineering is key to ignition success
In a room illuminated by blinking lights and glowing monitors, more than 2,000 synchronized computers are triggered to run 5 million lines of code. The intricate code language is responsible for aligning and firing 192 laser beams — and carrying some 800 channels of target diagnostic data — efficiently and reliably several times a day. This isn’t a scene from a science…
All eyes on Lynda Tesillo
For Lynda Tesillo, Women’s History Month means more than reflecting on the past. Her path to Lawrence Livermore National Laboratory started with studying engineering at a university — a decision which put her in a unique position within her family. “We had limited resources growing up, particularly when it came to affording an education,” Tesillo said. “At the time, my…
LLNL researchers develop method for real-time defect detection in metal 3D-printed parts
