For much of the past decade, Lawrence Livermore National Laboratory researchers have been designing major optical components for the world’s newest telescope, while their industrial partners have fabricated the components.
The earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory found that those variations are not caused by irradiation from the sun but are produced by condensation and evaporation reactions in the early solar system.
Lawrence Livermore National Laboratory (LLNL) scientists have developed a new approach using machine learning to study with unprecedented resolution the phase behaviors of superionic water found in the interiors of Uranus and Neptune.
Researchers at Lawrence Livermore National Laboratory are addressing the issue of porosity and other phenomenon that causes defects in metal 3D printing by exploring alternative shapes to the Gaussian beams commonly employed in high-power laser printing processes such as laser powder bed fusion (LBPF).
Lawrence Livermore National Laboratory (LLNL) scientists and collaborators proposed a new mechanism by which nuclear waste could spread in the environment. The new findings, that involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry.
For some diseases, people exposed to just a single airborne particle containing infectious virus, bacteria or fungi can be infected. When this happens, understanding and predicting airborne disease spread can be a whole lot easier. That’s the result of a new study by a Lawrence Livermore National Laboratory (LLNL) scientist who developed a new theory of airborne infectious disease spread.
Lawrence Livermore National Laboratory (LLNL) Director Emeritus George Miller has been named the 2021 recipient of the John S. Foster Medal for his contributions to U.S. national security.
Lawrence Livermore National Laboratory and its three partner national labs in the Bay Area Lab Innovation Networking Center (LINC) will offer a webinar about the future of semiconductors and advanced materials on Wednesday, Aug. 25.
Achieving fusion ignition – the process that powers the sun, stars and thermonuclear weapons – has been a decades-long goal for inertial confinement fusion research.
On Aug. 8, 2021, an experiment at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF) made a significant step toward ignition, achieving a yield of more than 1.3 megajoules (MJ). This is enabled by focusing laser light from NIF - the size of three football fields - onto a target the size of a BB that produces a hot-spot the diameter of a human hair, generating more than 10 quadrillion watts of fusion power for 100 trillionths of a second.
This advance puts researchers at the threshold of fusion ignition, an important goal of the NIF, and opens access to a new experimental regime.
Bradley Wallin has been named Lawrence Livermore National Laboratory’s (LLNL’s) principal associate director (PAD) for Weapons and Complex Integration (WCI), Lab Director Kimberly Budil announced today. In this role, Wallin will lead the Laboratory's nuclear weapons program in its responsibilities to support U.S. strategic deterrence by assuring the safety, security and effectiveness of the nation’s nuclear weapons stockpile and by providing the science, technology and engineering capabilities and experts required to enable and advance this essential responsibility.
To take advantage of the growing abundance and cheaper costs of renewable energy, Lawrence Livermore National Laboratory (LLNL) scientists and engineers are 3D printing flow-through electrodes (FTEs), core components of electrochemical reactors used for converting CO2 and other molecules to useful products.
Lawrence Livermore National Laboratory (LLNL) is one of 17 U.S. national laboratories entering a partnership with prominent publishers, journals and other organizations in scientific publishing to support name-change requests from researchers on past published papers.
A Lawrence Livermore National Laboratory scientist and collaborators have demonstrated the first ever “defect microscope” that can track how populations of defects deep inside macroscopic materials move collectively.
When the U.S. Space Force’s Tactically Responsive Launch-2 mission launched from Vandenberg Space Force Base on June 13, it carried a payload designed and built in record time by Lawrence Livermore National Laboratory.
Using wind tunnel measurements and computational fluid dynamics simulations, Lawrence Livermore National Laboratory (LLNL) engineers have demonstrated that aerodynamically integrated vehicle shapes decrease body-axis drag in a crosswind, creating large negative front pressures that effectively “pull” the vehicle forward against the wind, much like a sailboat.
Inspired by the way plants absorb and distribute water and nutrients, Lawrence Livermore National Laboratory researchers have developed a groundbreaking method for transporting liquids and gases using 3D-printed lattice design and capillary action phenomena.
Thousands of images of Earth and space have been taken by a compact space imaging payload developed by Lawrence Livermore National Laboratory (LLNL) researchers and its collaborator Tyvak Nano-Satellite Systems.
A Lawrence Livermore National Laboratory team has taken a closer look at how nuclear weapon blasts close to the Earth’s surface create complications in their effects and apparent yields. Attempts to correlate data from events with low heights of burst revealed a need to improve the theoretical treatment of strong blast waves rebounding from hard surfaces.
An international team of researchers, including scientists from Lawrence Livermore National Laboratory (LLNL), Sandia National Laboratories and the University of Hyogo, have used the world’s most energetic laser – LLNL’s National Ignition Facility (NIF) in Livermore, California – and the world’s most powerful pulsed-power facility – Sandia’s Z Machine in Albuquerque, New Mexico – to compress gold and platinum compress to 1 terapascal, deriving new pressure scales.
Scientists at Lawrence Livermore National Laboratory (LLNL) have determined that heating N95 respirators up to 75 degrees Celsius for 30 minutes deactivates a surrogate coronavirus without compromising the device’s fit and its ability to filter airborne particles.
