Lawrence Livermore National Laboratory (LLNL) is a federal research facility in Livermore, California, United States, founded by the University of California, Berkeley in 1952. Originally a branch of the Lawrence Berkeley National Laboratory, the Lawrence Livermore laboratory became autonomous in 1971 and was designated a national laboratory in 1981.

Charging up with carbon nanotubes

“Lawrence Livermore National Laboratory (LLNL) scientists have created vertically aligned single-walled carbon nanotubes on metal foils that could be a boon for energy storage and the electronics industry. Vertically aligned carbon nanotubes (VACNTs) have exceptional mechanical, electrical and transport properties …

National Ignition Facility achieves fusion ignition

“The U.S. Department of Energy (DOE) and DOE’s National Nuclear Security Administration (NNSA) today (Dec. 13) announced the achievement of fusion ignition at Lawrence Livermore National Laboratory (LLNL) — a major scientific breakthrough decades in the making that will …

Uranium takes an alternate pathway under extreme conditions

“Under normal conditions, radioactive materials such as uranium work in a predictable manner. But take those same materials and put them under extreme conditions with high temperature in a short timescale and a rapid cooling process and their decomposition pathways …

Scientists use carbon to detect a new nitrogen source in the open ocean

“Lawrence Livermore National Laboratory (LLNL) and UC Santa Cruz scientists have detected a previously hypothesized class of nitrogen fixation in the surface ocean. Nitrogen scarcity limits the growth of ocean phytoplankton, a globally important carbon sink and the base of …

From batteries to water purifiers, carbon nanotubes are where it’s at

“Lawrence Livermore National Laboratory (LLNL) scientists are scaling up the production of vertically aligned single-walled carbon nanotubes (SWCNT) that could revolutionize diverse commercial products ranging from rechargeable batteries, automotive parts and sporting goods to boat hulls and water filters. The …

Under pressure: solid matter takes on new behavior

“Investigating how solid matter behaves at enormous pressures, such as those found in the deep interiors of giant planets, is a great experimental challenge. To help address that challenge, Lawrence Livermore National Laboratory (LLNL) researchers and collaborators took a deep …

A deep dive into the interior of red dwarfs

“Red dwarfs are the most abundant stars in the Milky Way, making up 70% of all stars. But the physics of their interiors is not well understood. Heat is generated in the core and travels outward to the surface, but …

Oxygen effects on uranium tested

“A team of researchers from Lawrence Livermore National Laboratory (LLNL) and the University of Michigan has found that the rate of cooling in reactions dramatically affects the type of uranium molecules that form. The team’s experimental work, conducted over …

Breaking the strongest chemical bonds with laser shock compression

“Lawrence Livermore National Laboratory (LLNL) scientists recently obtained high-precision thermodynamic data on warm dense nitrogen at extreme conditions that could lead to a better understanding of the interiors of celestial objects like white dwarfs and exoplanets. The team, which includes …

Laser-based ultrasound detects defect-producing features in metal 3D printing

“Lawrence Livermore National Laboratory (LLNL) researchers have developed a new all-optical ultrasound technique capable of performing on-demand characterization of melt tracks and detecting formation of defects in a popular metal 3D printing process. In a paper published by Scientific Reports …
