3D-printed electrode is all charged up
The architectural design of electrodes offers new opportunities for next-generation electrochemical energy storage devices (EESDs) by increasing surface area, thickness and storage capacity. But conventional thick electrodes increase ion diffusion length and cause larger ion-concentration gradients, limiting reaction kinetics, including storage capacity. To overcome these…
Americans increase overall pace of decarbonization, but state trends vary
In 2023, Americans reduced their consumption of electricity and fossil fuels, while increasing consumption of carbon-free energies, according to the most recent energy and carbon flowcharts released by Lawrence Livermore National Laboratory (LLNL). Each year, LLNL releases these flowcharts to illustrate the nation's consumption and uses of energy, as well as associated CO2…

All ears on the Big Ideas Lab podcast
Lawrence Livermore National Laboratory (LLNL) has big ideas and is showing the world in the Big Ideas Lab weekly podcast that takes listeners behind the fences and into its heart. “This is where big ideas come to life,” said Lab Director Kim Budil. “To do this, we bring together dynamic teams of many different disciplines — laser physicists and materials scientists and…
Chemical production gets a cleaner boost
A new electrochemical method can make chemical production cleaner and more energy-efficient. Using thin film nickel anodes, a team of Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have figured out how to clean up chemical production. When studying a new electrochemical reaction, using thin films is important because they give a consistent…
It’s getting hot in here: lasers deliver powerful shocking punch
Shock experiments are widely used to understand the mechanical and electronic properties of matter under extreme conditions, like planetary impacts by meteorites. However, after the shock occurs, a clear description of the post-shock thermal state and its impacts on material properties is still lacking. Lawrence Livermore National Laboratory (LLNL) scientists used ultra…
Chemical and transportation industries could get a boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources — such as solar and wind — promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene, ethanol and acetic acid are particularly useful as feedstocks for the chemical industry and powering vehicles. While…
Fusion Power Associates honors Bruno Van Wonterghem
Bruno Van Wonterghem, operations manager at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF), was awarded a 2024 Distinguished Career Award by Fusion Power Associates (FPA). FPA board of directors recognized Van Wonterghem “for his decades of tenacious dedication to scientific and operational excellence in bringing both the LLNL Beamlet and…
LLNL’s Tammy Ma shares fusion energy vision with TED
What would you do with the largest laser in the world? That’s the question Lawrence Livermore National Laboratory (LLNL) physicist Tammy Ma posed to the audience on the mainstage at the influential TED conference held in April in Vancouver. In the talk, which was publicly released today, Ma shared her answer: bringing about a world powered by laser-based fusion energy,…
Confined water gets electric
When water gets inside nanopores with sizes below 10 nanometers, new physics emerge: new phases of ice were observed and ultrafast proton transport was measured. Confined water also plays a role in biology, where aquaporins cross cellular membranes to allow specific transport of water and other small molecules through nanometer-scale channels. However, this field lacks a…
LLNL researchers uncover key to resolving long-standing ICF hohlraum drive deficit
A team of researchers at Lawrence Livermore National Laboratory (LLNL) has made advancements in understanding and resolving the long-standing "drive-deficit" problem in indirect-drive inertial confinement fusion (ICF) experiments. This discovery could pave the way for more accurate predictions and improved performance in fusion experiments at the National Ignition Facility…
Unravelling the chemistry of heavy elements

When experiments go quiet: maintaining the National Ignition Facility
For two weeks last April, the lasers at Lawrence Livermore National Laboratory’s National Ignition Facility stopped firing. Experiments may have been on pause, but the facility was anything but quiet. “To do world-class science, you need a world-class facility. And you can’t just maintain that facility, you must anticipate problems and seek out improvements,” said Stanley…
