Checking out iron under pressure

“Iron is the most stable and heaviest chemical element produced by nucleosynthesis in stars, making it the most abundant heavy element in the universe and in the interiors of Earth and other rocky planets. To get a better understanding of …

Planetary defenders validate asteroid deflection code

“Planetary defense researchers at Lawrence Livermore National Laboratory (LLNL) continue to validate their ability to accurately simulate how they might deflect an Earth-bound asteroid in a study that will be published in the April issue of the American Geophysical Union …

World’s largest optical lens shipped to SLAC

“When the world’s newest telescope starts imaging the southern sky in 2023, it will take photos using optical assemblies designed by Lawrence Livermore National Laboratory (LLNL) researchers and built by Lab industrial partners. A key feature of the camera …

‘Quantum annealer’ shows promise in study

“An international team of researchers, including Lawrence Livermore National Laboratory (LLNL) physicist Arjun Gambhir, has developed a new algorithm for solving polynomial systems of equations using a type of quantum computer called a “quantum annealer.” The team systematically examined how …

Nanowire arrays could improve solar cells

“Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also need to be able …

3D-printed live cells convert glucose to ethanol, carbon dioxide to enhance catalytic efficiency

“Lawrence Livermore National Laboratory (LLNL) researchers have 3D printed live cells that convert glucose to ethanol and carbon dioxide gas (CO2), a substance that resembles beer, demonstrating a technology that can lead to high biocatalytic efficiency. Bioprinting living mammalian cells …

New multibeam metal 3D printer testbed to understand laser-material interactions

“Lawrence Livermore National Laboratory (LLNL) scientists and engineers have created the first research-grade, open-architecture multibeam metal 3D printer and are developing advanced diagnostics to understand the mechanics behind the multibeam process under a project funded by the Air Force Research …

Researchers look to computing’s past to unlock 3D-printed mechanical logic gates for the future

“Taking a page from the past, Lawrence Livermore National Laboratory scientists and engineers are combining mechanical computing with 3D printing as part of an effort to create “sentient” materials that can respond to changes in their surroundings, even in extreme …

Lab develops metamaterials that change mechanical properties under magnetic fields

“Lawrence Livermore National Laboratory (LLNL) researchers have introduced a new class of metamaterials that can nearly instantly respond and stiffen 3D-printed structures when exposed to a magnetic field, a development that could be applied to next-generation helmets, wearable armor and …

New algorithms to predict power grid impacts from hackers, earthquakes and - squirrels?

“What would it take for an entire American city to lose power? What circumstances and failures in the electrical grid’s infrastructure would lead to a dramatic, long-term blackout? And what weak points could utility companies invest in to help …
