New machine learning tool diagnoses electron beams in an efficient, non-invasive way

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

For the past few years, researchers at the Department of Energy's SLAC National Accelerator Laboratory have been developing "virtual diagnostics" that use machine learning to obtain crucial information about electron beam quality in an efficient, non-invasive way. Now, a new virtual diagnostic approach incorporates additional information about the beam that allows the method to work in situations where conventional diagnostics have failed.

First closeups of how a lithium-metal electrode ages

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Even when a device is turned off, its battery gradually loses its charge and eventually some of its capacity for storing energy. Scientists have now documented this aging process in next-gen lithium-metal electrodes.

Missing baryons found in far-out reaches of galactic halos

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Researchers have channeled the universe's earliest light - a relic of the universe's formation known as the cosmic microwave background - to solve a missing-matter mystery and learn new things about galaxy formation. Their work could also help us to better understand dark energy and test Einstein's theory of general relativity by providing new details about the rate at which galaxies are moving toward us or away from us.

Commercial truck electrification is within reach

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Researchers from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Los Angeles published a new study that makes the case for prioritizing public policy to help move long-haul trucking from diesel to electric. Doing so will mean huge gains in addressing the climate crisis and avoiding premature deaths due to local vehicular pollution, which disproportionately affects communities of color.

In a leap for battery research, machine learning gets scientific smarts

DOE/SLAC National Accelerator Laboratory
Peer-Reviewed Publication

Researchers combined machine learning with knowledge gained from experiments and equations guided by physics to discover and explain a process that shortens the lifetimes of fast-charging lithium-ion batteries.

A COSMIC approach to nanoscale science

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

COSMIC, a multipurpose X-ray instrument at Berkeley Lab's Advanced Light Source, has made headway in the scientific community since its launch less than 2 years ago, with groundbreaking contributions in fields ranging from batteries to biominerals.

HPC explorations of supernova explosions help physicists reach new milestones

DOE/Lawrence Berkeley National Laboratory

Physicists have been studying the question of how supernova explosions occur for more than 60 years. Thanks to the increasing power of supercomputing resources such as those at the National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory, they're moving ever closer to an answer.

On the line: Watching nanoparticles get in shape

DOE/Lawrence Berkeley National Laboratory
Peer-Reviewed Publication

Berkeley Lab scientists have captured real-time, high-resolution videos of liquid structures taking shape as nanoparticles form a solid-like layer at the interface between oil and water. Their findings could help advance all-liquid robotics for targeted cancer drug delivery and other applications.
