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’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. The team’s two-part “fast cure” silicone-based ink for direct ink writing mixes just before printing and sets quickly at room temperature, allowing for longer print times,…
Malik Wagih’s global exploration of material defects
Malik Wagih is a 2024 Lawrence Fellow in the Physical and Life Sciences Directorate’s Materials Science Division at Lawrence Livermore National Laboratory (LLNL), where he studies defects in metals. His journey to materials science research at Livermore has taken him across the country and the world. Wagih is originally from Cairo, Egypt, where he enjoyed playing soccer…
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…
LLNL’s Gauthier Deblonde selected as ‘Rising Star’
Lawrence Livermore National Laboratory (LLNL) staff scientist Gauthier Deblonde has been named a 2024 “Rising Star“ by the American Chemical Society for his work in environmental science. Deblonde’s research as well as this year’s cohort of winners will be featured in a special issue of the American Chemical Society journal ACS Environmental Au. Deblonde’s research also…
Plasma pursuits: HEDS Center fellows illuminate the fourth state of matter
In 2019, the High Energy Density Science (HEDS) Center at Lawrence Livermore National Laboratory (LLNL) launched its postdoctoral fellowship program, welcoming one new scientist annually to come and conduct research for a two-year term. Supported by LLNL’s Weapons Physics and Design program, HEDS fellows are encouraged to pursue their own research agenda as it relates to…
LLNL researchers explore next-gen 3D printing to harness fusion energy
When Lawrence Livermore National Laboratory (LLNL) achieved fusion ignition at the National Ignition Facility (NIF) in December 2022, the world’s attention turned to the prospect of how that breakthrough experiment — designed to secure the nation’s nuclear weapons stockpile — might also pave the way for virtually limitless, safe and carbon-free fusion energy. Advanced 3D…

Technology designed to aid on-the-field diagnostics for military applications is gaining a wider reach as Lawrence Livermore National Laboratory (LLNL) and BioVind, LLC achieved a milestone in their partnership: the exclusive licensing of LLNL pathogen diagnostics technology focused on oil and gas applications. The technology, called BioID, is a rapid and portable…
3D-printed electrode is all charged up
The architectural design of electrodes offers new opportunities for next-generation electrochemical energy storage devices (EESDs) by increasing surface area, thickness and storage capacity. But conventional thick electrodes increase ion diffusion length and cause larger ion-concentration gradients, limiting reaction kinetics, including storage capacity. To overcome these…
