Nuclear diagnostics help pave way to ignition on NIF

March 12, 2020- 
At its peak, a NIF inertial confinement fusion (ICF) implosion lasts about 100 trillionths of a second. The imploded fuel is a hundred millionths of a meter in diameter and as much as eight times denser than lead. The center of the imploded capsule is a few times hotter than the core of the sun. Developing a clear understanding of exactly what’s happening in a NIF implosion under those...

Observations of melting metal at the picosecond scale

Feb. 25, 2020- 
For the first time, Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have observed the shock melting and refreezing of a metal (zirconium) at the picosecond scale (trillionths of a second). Melting and freezing are some of the most common processes but can be difficult to understand since the fundamental mechanisms occur on near-atomic and picosecond timescales....

Glacier retreat study helps predictions of climate future

Feb. 20, 2020- 
Tropical glaciers in Africa and South America began their retreat simultaneously at the end of the last ice age about 20,000 years ago, according to a recent study by a multi-institutional research team that includes Lawrence Livermore National Laboratory’s (LLNL) Susan Zimmerman. The finding of synchrony in ice retreat across the global tropics clarifies how the low latitudes transformed...

Lab researchers develop 3D ‘brain-on-a-chip’ device capable of long-term recording of neural activity

Feb. 5, 2020- 
Lawrence Livermore National Laboratory (LLNL) engineers and biologists have developed a “brain-on-a-chip” device capable of recording the neural activity of living brain cell cultures in three dimensions, a significant advancement in the realistic modeling of the human brain outside of the body.  In a paper published by the journal Lab on a Chip, LLNL researchers report on the creation of...

Deep learning may provide solution for efficient charging, driving of autonomous electric vehicles

Feb. 4, 2020- 
The future of commuter traffic probably looks something like this: ride-hailing companies operating fleets of autonomous electric vehicles alongside an increasing number of semi-autonomous EVs co-piloted by humans, all supported by a large infrastructure of charging stations. This scenario is particularly likely in California, which has committed to reducing carbon emissions to 40 percent...

3D-printed aerogel electrodes boost energy storage

Jan. 29, 2020- 
A team of Lawrence Livermore National Laboratory (LLNL) scientists and collaborators from the University of California, Santa Cruz (UCSC) and Sun Yat-Sen University have developed a new class of aerogel electrodes with a simultaneous boost in energy and power density. The research could be a boon for the energy storage industry. “This is the first example in which we were able to boost...
