3D-printed glass enhances optical design flexibility

“Lawrence Livermore National Laboratory (LLNL) researchers have used multi-material 3D printing to create tailored gradient refractive index glass optics that could make for better military specialized eyewear and virtual reality goggles. The new technique could achieve a variety of conventional …

New materials help expand volumetric 3D printing

“Researchers at Lawrence Livermore National Laboratory (LLNL) have adapted a new class of materials for their groundbreaking volumetric 3D printing method that produces objects nearly instantly, greatly expanding the range of material properties achievable with the technique. The class of …

Simulations, high-speed videos help researchers see crack formation in 3D-printed tungsten in real time

“Boasting the highest melting and boiling points of all known elements, tungsten has become a popular choice for applications involving extreme temperatures, including lightbulb filaments, arc welding, radiation shielding and, more recently, as plasma-facing material in fusion reactors such as …

3D nanometer-thin membrane borrows from biology

“Mimicking the structure of the kidney, a team of scientists from Lawrence Livermore National Laboratory (LLNL) and the University of Illinois at Chicago (UIC) have created a three-dimensional nanometer (nm)-thin membrane that breaks the permeance-selectivity trade-off of artificial membranes …

Neuronal cultures advance ‘brain-on-a-chip’ technology

“Lawrence Livermore National Laboratory (LLNL) researchers have increased the complexity of neuronal cultures grown on microelectrode arrays, a key step toward more accurately reproducing the cellular composition of the human brain outside the body. As described in a recently published …

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 …
