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…

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…
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
Lawrence Livermore National Laboratory (LLNL) researchers have been recognized with the Journal of Alloys and Compounds’ 2024 best paper award for their publication, “Microstructural, phase, and thermophysical stability of CrMoNbV refractory multi-principal element alloys.” The paper examines alloys that have the potential to operate at high temperatures, a feature that…
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…
Toxin-antitoxin systems could target invasive and resistant bacteria
In a counterintuitive move, bacteria are known to produce self-destructive toxins. However, they also make antitoxins, and researchers at Lawrence Livermore National Laboratory (LLNL) have identified these toxin-antitoxin systems as a possible passkey to hack into bacteria communities. The study, recently published in Molecular Biology and Evolution, examines bacteria at a…
Big Ideas Podcast tackles the road to carbon removal
Lawrence Livermore National Laboratory (LLNL) has released a new episode of the Big Ideas Lab Podcast, focusing on the critical efforts being made to help remove carbon dioxide from the atmosphere. The episode provides insights into how 68 researchers nationwide came up with a comprehensive analysis of the capacity and costs for carbon dioxide removal at a county level…
Ramping up the scale of climate and energy technology
One of the biggest challenges implementing energy and climate technologies is actually scaling it up to deploy it. While scale-up has largely been the domain of industrial R&D teams, advances in modelling and experimental techniques increasingly allow early-stage researchers like those at Lawrence Livermore National Laboratory (LLNL) to contribute to the process. In a…
John H. Nuckolls receives Enrico Fermi Presidential Award
The Biden-Harris Administration has recognized former Lawrence Livermore National Laboratory (LLNL) director John H. Nuckolls with the Enrico Fermi Award, one of the oldest and most prestigious science and technology honors bestowed by the U.S. government. The award will be shared with two other scientists, Héctor D. Abruña and Paul Alivisatos. Nuckols was selected “for…
'Lighting' up antineutrino detection
How do you find and measure nuclear particles, like antineutrinos, that travel near the speed of light? Antineutrinos are the antimatter partner of a neutrino, one of nature’s most elusive and least understood subatomic particles. They are commonly observed near nuclear reactors, which emit copious amounts of antineutrinos, but they also are found abundantly throughout the…
Predicting atomic structures proves useful in energy and sustainability
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new approach that combines generative artificial intelligence (AI) and first-principles simulations to predict three-dimensional (3D) atomic structures of highly complex materials. This research highlights LLNL’s efforts in advancing machine learning for materials science research and supporting…
Fast-curing silicone ink opens new doors in 3D printing
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a new method to 3D print sturdy silicone structures that are bigger, taller, thinner and more porous than ever before.

Measuring in-situ ablation depth in aluminum
When laser energy is deposited in a target material, numerous complex processes take place at length and time scales that are too small to visually observe. To study and ultimately fine-tune such processes, researchers look to computer modeling. However, these simulations rely on accurate equation of state (EOS) models to describe the thermodynamic properties — such as…
