LLNL looks to revolutionize 3D printing through microwave technology
In the rapidly evolving world of 3D printing, the pursuit of faster, more efficient and versatile production methods is never-ending. Traditional 3D printing techniques, while groundbreaking, are often time-consuming and limited in the kinds of materials they can use as feedstock. But, through a new process a Lawrence Livermore National Laboratory (LLNL) team is calling…
All ears on the Big Ideas Lab podcast
Lawrence Livermore National Laboratory (LLNL) has big ideas and is showing the world in the Big Ideas Lab weekly podcast that takes listeners behind the fences and into its heart. “This is where big ideas come to life,” said Lab Director Kim Budil. “To do this, we bring together dynamic teams of many different disciplines — laser physicists and materials scientists and…
Unveiling the key factors that determine properties of porous polymer materials
Determining the relationship between microstructure features and their properties is crucial for improving material performance and advancing the design of next-generation structural and functional materials. However, this task is inherently challenging. To address the challenges, LLNL scientists developed an efficient and comprehensive computational framework to decipher…
Chemical production gets a cleaner boost
A new electrochemical method can make chemical production cleaner and more energy-efficient. Using thin film nickel anodes, a team of Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have figured out how to clean up chemical production. When studying a new electrochemical reaction, using thin films is important because they give a consistent…
It’s getting hot in here: lasers deliver powerful shocking punch
Shock experiments are widely used to understand the mechanical and electronic properties of matter under extreme conditions, like planetary impacts by meteorites. However, after the shock occurs, a clear description of the post-shock thermal state and its impacts on material properties is still lacking. Lawrence Livermore National Laboratory (LLNL) scientists used ultra…
Molecules get a boost from metallic carbon nanotubes
A Lawrence Livermore National Laboratory (LLNL) team has found that pure metallic carbon nanotubes are best at transporting molecules. Molecule separations play an ever-increasing role in modern technology from water desalination to harvesting critical materials to high-value chemicals and pharmaceuticals manufacturing. To enhance water and proton transport, LLNL…
Chemical and transportation industries could get a boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources — such as solar and wind — promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene, ethanol and acetic acid are particularly useful as feedstocks for the chemical industry and powering vehicles. While…
Signal and image science community comes together for annual workshop
Nearly 150 members of the signal and image science community recently came together to discuss the latest advances in the field and connect with colleagues, friends and potential collaborators at the 28th annual Center for Advanced Image and Signal Science (CASIS) workshop. Held at the University of California Livermore Collaboration Center (UCLCC) for the first time, the…
DOE, LLNL take center stage at inaugural artificial-intelligence expo
Lawrence Livermore National Laboratory (LLNL) Director Kim Budil and other LLNL staff joined Department of Energy (DOE) Deputy Secretary David Turk, National Nuclear Security Administration (NNSA) Administrator Jill Hruby, DOE Under Secretary for Science and Innovation Geraldine Richmond, DOE Director of the Office of Critical and Emerging Technologies Helena Fu, U.S…
Manufacturing optimized designs for high explosives
When materials are subjected to extreme environments, they face the risk of mixing together. This mixing may result in hydrodynamic instabilities, yielding undesirable side effects. Such instabilities present a grand challenge across multiple disciplines, especially in astrophysics, combustion and shaped charges — a device used to focus the energy of a detonating explosive…
LLNL hosts Early Career Information Day focused on advanced materials and manufacturing
The University of California (UC) and Lawrence Livermore National Laboratory (LLNL) have a storied history going back to the founding of the Laboratory in 1952. The work conducted at the Lab since that time has benefited in many areas from successful collaboration with researchers and contributors within the UC system. 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…

Looking to advance your career in machining? The annual job posting for Lawrence Livermore National Laboratory’s (LLNL’s) esteemed machinist apprenticeship will go live in January and will accept applications for approximately one month. The California-certified program is one of the oldest in the nation, and one of the most unique. Apprentices are trained in LLNL’s…
Probing the temperature of materials under extreme pressure
In new experiments at Lawrence Livermore National Laboratory’s National Ignition Facility, scientists measured the extended X-ray absorption fine structure (EXAFS) of copper to probe its temperature under extreme pressure. The research appears in the journal Nature Communications. Dynamic compression experiments at high-energy-density laser facilities have expanded the…
LLNL hosts HBCU students, faculty to build new pipeline of talent
For the second consecutive year, Lawrence Livermore National Laboratory (LLNL) hosted a group of student scholars and faculty members from Historically Black Colleges and Universities (HBCUs) on a recent five-day visit. LLNL’s goal is to develop the next wave of summer interns — and to build a strong pipeline of talent — from historically marginalized groups in science,…
LLNL’s Feaster named to American Institute for Chemical Engineering’s '35 Under 35' class for 2023
