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…

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…

STEM San Joaquin celebrates third year of inspiring young minds

STEM San Joaquin marked its third anniversary on Saturday, Nov. 15, at the University of the Pacific (UOP) in Stockton. Co-sponsored by Lawrence Livermore National Laboratory (LLNL) and UOP, the annual event welcomed students in grades 6–9 for a day of hands-on science, technology, engineering and math (STEM) exploration. The conference is organized by a dedicated team of…

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…

Meet LLNL: Senior Engineering Technologist Jose Hernandez

Seven years ago, Jose Julian Hernandez took a chance on an internship at Lawrence Livermore National Laboratory (LLNL). Today, he is a senior engineering technologist at LLNL’s Center for Micro- and Nanotechnology, providing engineering support for projects ranging from medical implantable devices for neural research to custom-engineered products for various Laboratory…

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…

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 welcomes six new machinist apprentices in signing ceremony

Lawrence Livermore National Laboratory (LLNL) welcomed six new members into its prestigious machinist apprenticeship program during a signing ceremony held July 24. The event, attended by Lab leadership, supervisors and state officials, marked the official start of a four-year journey in advanced manufacturing for the new cohort. The apprentices — Ace Jenkins, John Burns,…

LLNL team tackles support structure bottlenecks with dual-wavelength 3D printing

Lawrence Livermore National Laboratory (LLNL) researchers have developed a novel 3D printing technique that uses light to build complex structures, then cleanly dissolves the support material, expanding possibilities in multi-material additive manufacturing (AM). In 3D printing, traditional supports often add time, waste and risk to the process, especially when printing…
