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 …
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…
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…
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…
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…
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)…
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…
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…
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…
Lawrence Livermore National Laboratory (LLNL) engineers and scientists have developed a method for detecting and predicting strut defects in 3D-printed metal lattice structures during a print through a combination of monitoring, imaging techniques and multi-physics simulations. The high-strength and low-density properties of metallic lattices have found applications in…
Who: Stan Hitomi, retired educator and district administrator for the San Ramon Valley Unified School District, will present “3D Printing: From Imagination to Realization” joined by a host of Lawrence Livermore National Laboratory (LLNL) scientists, including: Eric Duoss, Julie Mancini, Monica Moya, Dominique Porcincula, William Smith, Chris Spadaccini and Becca Walton…
New research led by Lawrence Livermore National Laboratory (LLNL) provides a better understanding of ejecta production, which has been the subject of broad interest for more than 60 years throughout the scientific community. Ejecta are particles of material forced out or ejected from an area. The phenomena are observed across many multi-disciplinary applications, including…
Lawrence Livermore National Laboratory (LLNL) is celebrating National Engineers Week (Feb. 19-Feb. 25) and Introduce a Girl to Engineering Day (Feb. 23) by highlighting just a few of the more than 2,500 employees that make up the Lab’s Engineering Directorate. Representing a cross-section of the broad scope of focus areas and disciplines comprising the directorate,…
Lawrence Livermore National Laboraotry (LLNL) engineers have taken major strides towards closing the gap between the Lab’s manufacturing and design capabilities. The field of additive manufacturing, or 3D printing, has enabled the manufacturing of a variety of heretofore impossible designs — but some of this potential is left on the table because designers have had trouble…
Lawrence Livermore National Laboratory (LLNL) scientists and engineers led a multi-institutional team in executing a series of high explosives tests that successfully demonstrated fundamental principles of anisotropy, a possible enabler for improved weapon and munition safety. Working under snowy and frigid conditions on Idaho’s Snake River Plain, a 13-member team from…
A new joint initiative between the Lawrence Livermore National Laboratory (LLNL) Weapons and Complex Integration (WCI) Directorate and the University of California (UC) is aimed at developing next generation academic leadership with strong and enduring national laboratory connections. The LLNL Early Career UC Faculty Initiative is accepting proposals from untenured, tenure…
The W80-4 Life Extension Program team in November successfully executed the Preliminary Design Review and Acceptance Group (PDRAAG) review at the Air Force Nuclear Weapons Center on Kirtland Air Force Base in Albuquerque, New Mexico. Review by the PDRAAG is a critical mid-program review with the Department of Defense to show the warhead baseline design complies with DOD…
"Dwell fatigue" is a phenomenon that can occur in titanium alloys when held under stress, such as a jet engine's fan disc during takeoff. This peculiar failure mode can initiate microscopic cracks that drastically reduce a component's lifetime. The most widely used titanium alloy, Ti-6Al-4V, was not believed to exhibit dwell fatigue before the 2017 Air France Flight 066…
While Lawrence Livermore National Laboratory is eagerly awaiting the arrival of its first exascale-class supercomputer, El Capitan, physicists and computer scientists running scientific applications on testbeds for the machine are getting a taste of what to expect. “I'm not exactly sure we’ve wrapped our head around exactly about how much compute power [El Capitan] is…
