Undergraduate interns explore nuclear physics research at LLNL
Scientists at Lawrence Livermore National Laboratory (LLNL) recently helped launch a new internship program aimed at connecting with undergraduate students at two nearby California State University (CSU) campuses and inspiring them to consider a science-focused research career. The new program, which started in early 2025, involves multiple staff and postdocs from the Lab…
Energy-efficient process delivers rare-earth element for magnets
Neodymium is a rare-earth element essential for producing the strongest permanent magnets, which are widespread in defense technologies, hard drives, medical imaging devices, electric vehicle motors, wind turbines and more. Despite its designation in the U.S. as a critical material, neodymium is primarily mined and refined overseas. China controls much of the supply chain,…
Turning wastewater into valuable fertilizer
Almost half of the planet’s population depends on synthetic fertilizers to grow the food they eat. But that fertilizer comes at a cost — about two percent of the world’s energy budget. Improving efficiency and cutting costs of producing fertilizer would have big, global impacts. To that end, researchers at Lawrence Livermore National Laboratory (LLNL) are developing a…
LLNL conducts milestone nuclear survivability experiment at NIF, moving weapons modernization forward
Lawrence Livermore National Laboratory (LLNL) has conducted an experiment at the National Ignition Facility (NIF) to assess the ability of U.S. nuclear weapons to survive encounters with adversary missile defenses and reach their targets. This experiment demonstrated a new capability to analyze nuclear materials under extreme conditions, advancing stockpile modernization…
From inception to ignition and beyond: Suhas Bhandarkar’s target fabrication career
Tiny parts and absolute meticulousness define Suhas Bhandarkar’s award-winning 20-year career at Lawrence Livermore National Laboratory (LLNL). As group leader for Target Fabrication Science and Technology (S&T), he leads a team that helps transform LLNL’s physicists’ bold ideas into reality at the National Ignition Facility (NIF). Bhandarkar’s path began with a B.S…
LLNL’s designs enable delivery of W80-4 subassembly First Production Unit ahead of schedule
The National Nuclear Security Administration (NNSA) recently announced the diamond stamping of the first production unit (FPU) of a canned subassembly (CSA) for the W80-4 Life Extension Program, achieved 18 months ahead of schedule at the Y-12 National Security Complex in Oak Ridge, Tennessee. As design agency for the W80-4, Lawrence Livermore National Laboratory (LLNL)…
Meteorite samples are time capsules from the early solar system
When a meteor streaks across the sky, it’s not just beautiful. It’s nature’s way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed. Lawrence Livermore National Laboratory (LLNL) scientist Thomas Kruijer and collaborators describe how meteorites tell the story of the…
Watching gold change structure at extreme pressures
The inside of giant planets can reach pressures more than one million times the Earth’s atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties. Understanding matter in this regime requires experiments that push the limits of physics in the laboratory. In a recent paper published in Physical Review Letters, researchers at…
Researchers discover entirely new phase of ice
Water is weird. When ice cubes float at the top of a drink, they’re defying the norm. Solids are generally denser than liquids, so they sink. But because of its hydrogen bonds, water produces unusual and complex behaviors. Studying water ice and its various phases is crucial for understanding its strange properties. The knowledge is also critical for materials science,…
Unique resin allows 3D-printing method to add and subtract
Additive manufacturing, or 3D printing, is normally a one-way street. In a digital light processing (DLP) printer, a structured pattern is projected onto a layer of liquid resin, which cures and solidifies. This builds an object up, layer-by-layer. But if the print isn’t exactly right, there’s no easy way to fix it after the fact: it usually ends up in the trash. In a new…
California awards grant to LLNL and DarmokTech to develop recyclable sodium batteries
Lithium-ion batteries are everywhere: in phones, computers and more. The technology primarily uses liquid electrolytes, which facilitate charge moving from electrode to electrode, but they can also leak, short-circuit the battery and — in some cases — cause fires. In broader applications such as electrical grid storage, lithium scarcity also makes it difficult to rely on…
Enabling an enabling technology
With the ability to print metal structures with complex shapes and unique mechanical properties, metal additive manufacturing (AM) could be revolutionary. However, without a better understanding of how metal AM structures behave as they are 3D printed, the technology remains too unreliable for widespread adoption in manufacturing and part quality remains a challenge…
Miniaturized ion traps show promise of 3D printing for quantum-computing hardware
Researchers at Lawrence Livermore National Laboratory (LLNL), the University of California (UC) Berkeley, UC Riverside and UC Santa Barbara have miniaturized quadrupole ion traps for the first time with 3D printing — a breakthrough in one of the most promising approaches to building a large-scale quantum computer. Quadrupole ion traps have four electrode poles that create…
LLNL’s Xiaoxing Xia named among MIT Technology Review’s top Innovators Under 35
MIT Technology Review has named Lawrence Livermore National Laboratory (LLNL) research scientist Xiaoxing Xia as one of its 2025 Innovators Under 35 — a global list honoring early-career researchers and entrepreneurs who are shaping the future of science and technology. The publication recognized Xia in the Inventors category for his groundbreaking advances in developing…
LLNL aims to learn faster with science of scale-up
The science of scale-up enables a faster and more reliable advancement of technology from research and development through commercial deployment. Using techniques like computer modeling and advanced manufacturing, teams can compress the technology scale-up timeline, which can include making something bigger, more numerous, faster or more repeatably. Accelerating scale-up…
Modeling materials defects: LLNL interns explore nanotubes and batteries
For more than 20 years, the Computational Chemistry and Materials Science (CCMS) internship program at Lawrence Livermore National Laboratory (LLNL) has offered students the opportunity to develop and apply computational methods to predict, analyze and optimize the properties of materials for a broad range of applications. “Many of our interns come back to LLNL as a…
Lab scientists win four 2025 R&D 100 awards
Lawrence Livermore National Laboratory (LLNL) scientists and engineers have earned four awards among the top 100 inventions worldwide. The trade journal R&D World Magazine recently announced the winners of the awards, often called the “Oscars of innovation,” recognizing new commercial products, technologies and materials that are available for sale or license for their…
When carbon crystallizes: molecular simulations reveal why graphite outshines diamond
There’s a reason why engagement rings are more expensive than wooden pencils. Diamond and graphite are both made of crystallized carbon, but diamond is much rarer. In a study published in Nature Communications, researchers including Margaret Berrens at Lawrence Livermore National Laboratory (LLNL) created molecular dynamics simulations to explain what material forms when…
Carbon nanotube ‘smart windows’ offer energy savings
Half of the sun's radiant energy falls outside of the visible spectrum. On a cold day, this extra infrared light provides additional warmth to residential and commercial buildings. On a warm day, it leads to unwanted heating that must be dealt with through energy-intensive climate control methods such as air-conditioning. Visibly transparent “smart windows” that can…
