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…
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…
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…
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…
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…
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…
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…
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…
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…
This summer, Lawrence Livermore National Laboratory (LLNL) hosted science education programs that provided students with hands-on experience related to several LLNL research themes. The science education offerings for this summer included three standout programs: the Manufacturing Workshop, STEM with Phones and the Biotech Summer Experience. The Manufacturing Workshop The…
Scientists at Lawrence Livermore National Laboratory (LLNL) and their collaborators have created a new class of programmable soft materials that can absorb impacts like never before, while also changing shape when heated. The research — which includes collaborators from Harvard University, the California Institute of Technology (Caltech), Sandia National Laboratories and…
Normally, materials expand when heated. Higher temperatures cause atoms to vibrate, bounce around and take up a larger volume. However, for one specific phase of plutonium — called delta-plutonium — the opposite inexplicably occurs: it shrinks above room temperature. As part of its national security mission, Lawrence Livermore National Laboratory (LLNL) aims to predict the…
Pure metals like aluminum or titanium don’t always have the desired material properties — strength, hardness, ductility or corrosion resistance — for a given application. For this reason, researchers seek out novel alloy solutions, mixing a primary metal element with a series of other elements to create a material with tailored properties for uses in aerospace, defense,…
It can be found inside gas giants such as Jupiter and is briefly created during meteorite impacts or in laser fusion experiments: warm dense matter. This exotic state of matter combines features of solid, liquid and gaseous phases. Until now, simulating warm dense matter accurately has been considered a major challenge. An international team led by researchers from the…
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…
The Scialog: Automating Chemical Laboratories initiative has awarded Lawrence Livermore National Laboratory (LLNL) scientist Johanna Schwartz $60,000 to pursue automated design of next-generation membranes for fuel cells. The award comes as one of seven collaborative projects funded by the Research Corporation for Science Advancement (RCSA), the Arnold and Mabel Beckman…
The latest episode of Lawrence Livermore National Laboratory’s (LLNL) Big Ideas Lab podcast explores how engineers and scientists are reducing the time it takes to design and deliver critical components for the U.S. nuclear deterrent — by rethinking how design and manufacturing teams work together. Listen here on Spotify or Apple. The episode features LLNL’s Polymer…
By splitting water molecules, fuel cells can turn electricity into hydrogen fuel. Running in the opposite direction, they consume hydrogen fuel to cleanly power multiple sectors. Typically, heat is a key ingredient for achieving high energy conversion efficiencies that can beat out combustion-based engines. But like a dripping pipe, fuel cells can leak efficiency. In a new…
Near-infrared photodetectors are used in biomedical sensing and defense and security technologies. For enhanced performance and integrated, compact imaging systems, the photodetectors must be able to detect multiple wavelengths of light at once on a single chip. Quantum dots — tiny crystals made of semiconducting material — could present a path forward because different…
Doctoral student Natalie Yaw came to Lawrence Livermore National Laboratory (LLNL) as a summer intern. But when her time at the Laboratory ended, her work did not. She took the lead to write a paper based on her findings, and the result was published in Inorganic Chemistry Frontiers. As a Department of Energy Nuclear Energy University Program fellow, Yaw chose to intern at…
