3D-printed helixes show promise as THz optical materials
Researchers at Lawrence Livermore National Laboratory (LLNL) have optimized and 3D-printed helix structures as optical materials for Terahertz (THz) frequencies, a potential way to address a technology gap for next-generation telecommunications, non-destructive evaluation, chemical/biological sensing and more. The printed microscale helixes reliably create circularly…
LZ dark matter experiment sets a world’s best and spots neutrinos from the sun’s core
There’s more to the universe than meets the eye. Dark matter, the invisible substance that accounts for 85 percent of the mass in the universe, is hiding all around us — and figuring out exactly what it is remains one of the biggest questions about how our world works. The newest results from LUX-ZEPLIN (LZ) extend the experiment’s search for low-mass dark matter and set…
LLNL and Energy I-Corps take science from big ideas to big market impact
Lawrence Livermore National Laboratory (LLNL) pursues big ideas to solve the most important security challenges facing the U.S. and the world. In that pursuit, scientific breakthroughs with market potential are discovered, protected and licensed to (or collaborated on) with industry partners through a process called technology transfer. LLNL’s Innovation and Partnerships…
LLNL caps SC25 with HPC leadership, major science advances and artificial intelligence
Lawrence Livermore National Laboratory (LLNL) capped a milestone week at the International Conference for High Performance Computing, Networking, Storage, and Analysis (SC25) with renewed leadership in supercomputing on the Top500, a Gordon Bell Prize win for real-time tsunami forecasting and a slate of sessions that underscored the Lab’s expanding role at the intersection…
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…
