Research provides insights into aluminum’s optical properties
Aluminum is an important material for a variety of scientific and technological applications, including plasma physics, astrophysics, semiconductor photolithography, and instrumentation for short wavelengths (ultraviolet [UV], extreme ultraviolet [EUV], and x-ray). Despite this common use—and a wealth of experimental data about aluminum—there is still a lack of accurate…
LLNL to examine exoplanet atmospheres with high-performance computing
The NASA/ESA/CSA James Webb Space Telescope (JWST) is the largest, most powerful and most complex telescope ever launched into space. Three years into its operations, JWST is revolutionizing our understanding of planets beyond our own solar system by collecting rich datasets on the atmospheres of these far-away worlds. However, data alone is not enough to understand our…

Assessing groundwater contamination risks near the Zaporizhzhia Nuclear Power Plant
As the war in Ukraine continues, the risk of environmental disasters grows, particularly around critical infrastructure like the Zaporizhzhia Nuclear Power Plant (NPP). LLNL and collaborators recently conducted a study, published in ACS EST Water, to assess the vulnerability of groundwater contamination in the region surrounding the nuclear power plant, using a model…
Four LLNL teams to attend Energy I-Corps Cohort 20
In a record setting year for Lawrence Livermore National Laboratory (LLNL), four teams of LLNL researchers will attend the Department of Energy’s (DOE) Energy I-Corps (EIC) Cohort 20 this spring. The EIC is a key initiative of the DOE’s Office of Technology Transitions, and facilitated at LLNL by Hannah Farquar from the Innovation and Partnerships Office (IPO). Established…
Quantum computers successfully model particle scattering
Scattering takes place across the universe at large and miniscule scales. Billiard balls clank off each other in bars, the nuclei of atoms collide to power the stars and create heavy elements, and even sound waves deviate from their original trajectory when they hit particles in the air. Understanding such scattering can lead to discoveries about the forces that govern the…
New program aims to fast-track energetic materials education for researchers
More than 80 physicists, chemists, material scientists and engineers participated in a new educational program at Lawrence Livermore National Laboratory (LLNL) during 2024, developed and delivered by the Lab’s energetic materials experts. As hiring at LLNL accelerated in recent years, Lab leaders recognized the growing need to provide specialized training for newer members…
Assessing adverse neurological effects of wildfire smoke inhalation
Following the devastating fires that swept through Los Angeles in January, concerns are on the rise about the long-term health impacts of smoke inhalation. In a study published in the International Journal of Molecular Sciences, researchers from Lawrence Livermore National Laboratory (LLNL) and the Environmental Protection Agency seek to close the knowledge gap on how…
LLNL researchers quantify metal strength uncertainty in high-explosives models
For the first time, a team of researchers at Lawrence Livermore National Laboratory (LLNL) quantified and rigorously studied the effect of metal strength on accurately modeling coupled metal/high explosive (HE) experiments, shedding light on an elusive variable in an important model for national security and defense applications. The team used a Bayesian approach to…
LLNL supports CO2 storage in California’s delta
The U.S. Department of Energy’s Office of Fossil Energy and Carbon Management (FECM) has awarded $6 million to Lawrence Livermore National Laboratory (LLNL) researchers, as part of a $45.2 million award to a team led by Pelican Renewables LLC, to develop a regional CO2 storage hub in California’s Sacramento-San Joaquin Delta in California. The funding came through FECM’s…
Identifying material properties for more efficient solid-state batteries
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a novel, integrated modeling approach to identify and improve key interface and microstructural features in complex materials typically used for advanced batteries. The work helped unravel the relationship between material microstructure and key properties and better predict how those properties…
LLNL hosts Nuclear Science and Security Consortium workshop
Once a year, a community of university professors, students and national lab researchers who focus on nuclear science and security gather to share research updates and develop collaborations, among other tasks. The group — known as the Nuclear Science and Security Consortium (NSSC) — recently held its workshop at the Lawrence Livermore National Laboratory (LLNL). The NSSC…
Big Ideas Lab Podcast takes on earthquakes and nuclear explosions
What do an earthquake, a mine collapse and a nuclear explosion have in common? Learn the answer to this question and more on a new episode of the Big Ideas Lab Podcast from Lawrence Livermore National Laboratory (LLNL). The episode provides insights into how Lab scientists monitor seismic activities such as earthquakes and nuclear explosions to ensure the safety of people…
Decarbonizing the cement industry
Cement, the essential binder of concrete—the most used material worldwide, only second to water—is produced at over four gigatonnes per year and contributes to 8% of global carbon dioxide (CO2) emissions. With the annual global demand for cement projected to increase by 50% by 2050, there is an urgent need to incorporate carbon capture, utilization, and storage…
Three LLNL scientists honored with presidential early-career award
In an announcement this week, President Biden awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) to nearly 400 distinguished scientists and engineers, recognizing their exceptional contributions and potential for leadership in their research fields. Among the honorees are three distinguished researchers from Lawrence Livermore National…
Improving vaccine stability and immunological response
Many vaccines that have been or are in the process of being developed, continue to face certain challenges when deployed worldwide. The practical impacts of vaccines are often compromised by common challenges, particularly, all currently licensed vaccines require sustained refrigeration, known as the “cold chain.” Under a strategic partnership, LLNL, the University of New…
LLNL creates world’s brightest X-ray source with NIF and novel metal foams
By combining the National Ignition Facility (NIF) laser and ultra-light metal foams, researchers at Lawrence Livermore National Laboratory (LLNL) have produced the brightest X-ray source to date — about twice as bright as previous solid metal versions. These ultra-bright high-energy X-rays can be used to image and study extremely dense matter, like the plasmas created…
LLNL’s computationally designed alloys capture best paper of the year award

Nanobubble formation observed during water electrolysis
Water electrolysis is a critical technology for producing hydrogen and is expected to play an important role in decarbonizing the global economy. With the manufacturing capacity of hydrogen expected to increase to approximately 130 gigawatts a year by 2030 (just one gigawatt equals 100 million LED bulbs), water electrolysis must perform at peak efficiency. As water…
Samples from the surface needed to unravel history of Mars
Geologically, Mars is very reminiscent of the moon. But it also looks a lot like the Earth. It all depends on who you ask. Current understanding of Mars’ evolution is based on spacecraft measurements and meteorite analysis. Those meteorites were ejected from Mars and traversed space before landing on Earth, where they were discovered primarily in African deserts and…
