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…

The recognition honors chemical engineers under the age of 35 who have made outstanding contributions to their field and to the chemical engineering community, according to the…
Two LLNL scientists selected as 2023 American Physical Society fellows
Lawrence Livermore National Laboratory (LLNL) scientists Manyalibo “Ibo” Matthews and Frank Graziani have been named 2023 American Physical Society (APS) fellows. Matthews was selected from the Forum in Industrial and Applied Physics unit “for pioneering research in optimizing metal 3D printing and laser materials processing.” Frank Graziani was chosen from the Division of…
In a first, LLNL researchers create birefringent all-glass metasurface
Lawrence Livermore National Laboratory (LLNL) researchers have adapted their novel metasurface process, which creates a thin layer on the surface of an optic, to create an all-glass metasurface with birefringence, or dual refraction, properties. This achievement could transform waveplate technology for high-power laser systems such as the National Ignition Facility (NIF)…
PLS postdocs excel at the 2023 Research Slam
On Thursday, August 24, a dozen LLNL postdocs presented in the annual Postdoctoral Research Slam, answering the question “Why is my research important?” in only three minutes. Each talk was then evaluated by LLNL leadership, awarding first and second place to PLS postdocs Brandon Zimmerman and Aditya Prajapati, respectively. As a bonus, the attending audience voted on…
Unlocking gas phase uranium oxidation is key to nuclear debris modeling
In the quest to understand how nuclear debris forms, a team of scientists at Lawrence Livermore National Laboratory (LLNL) has developed an approach to studying the oxidation mechanism of gas phase uranium in extreme environments. In research recently published in Scientific Reports, the team outlined their work, which combined experimental data from a plasma flow reactor …
LLNL and Meta engineers develop 3D-printed material with potential for more lifelike wearables
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 chemistry leads to more robust carbon capture materials
In a significant stride toward implementing scalable climate solutions, Lawrence Livermore National Laboratory (LLNL) scientists have uncovered how some carbon capture materials have improved lifetime compared to others. These materials are key in addressing greenhouse gas emissions and global warming concerns. Researchers have shed light on the mechanism that empowers…
Breaking down barriers: Sharee Harris shares her career story
A common misconception is that those interested in technical roles at a national laboratory must hold a graduate degree such as a Ph.D. On the contrary, roughly 40% of the science, technology and engineering workforce at Lawrence Livermore National Laboratory (LLNL) claim an associate’s or bachelor’s degree as their highest education level. This false narrative is…
Matter at extremes: a question of scale
Scaling laws are like a secret code used across science to break down complex phenomena into simple mathematical expressions. These equations help us to understand how one factor in a system relates to other factors that determine the system’s behavior. For example, Kleiber’s Law, one of the best-known scaling laws, observes that metabolic rates of many organisms — from…
New Lab projects to promote STEM diversity, accelerate battery research
Lawrence Livermore National Laboratory (LLNL) will partner with outside institutions to improve diversity in the STEM workforce and provide training to underrepresented students and researchers under a pair of projects recently funded by the Department of Energy. With support from DOE’s Funding for Accelerated, Inclusive Research (FAIR) initiative, LLNL will partner with…
Understanding the plasticity of diamond for improved fusion ignition
Alex Li, a Lawrence Livermore National Laboratory (LLNL) summer student in the Computational Chemistry and Materials Science Summer Institute, recently led a study published in the journal Matter to investigate the evolution of plasticity in diamond along different loading orientations and the effects that voids (pores) within the material can have on stresses within the…
New research shows successful ab initio crystal structure prediction of energetic materials
New research by Lawrence Livermore National Laboratory researchers and collaborators from Carnegie Mellon University (CMU) demonstrates that crystal structure prediction is a useful tool for studying the various ways the molecules can pack together, also known as ubiquitous polymorphism, in energetic materials.
