Human-caused climate change increases wildfire activity

Nov. 8, 2021- 
The western United States has experienced a rapid increase of fire weather as the vapor pressure deficit (VPD) increases in the area during the warm season. New research by scientists at University of California, Los Angeles (UCLA) and Lawrence Livermore National Laboratory (LLNL) shows that two-thirds (approximately 68 percent) of the increase in VPD is due to human-caused climate change...

Disorder in surface materials key to better hydrogen storage

Nov. 4, 2021- 
Lawrence Livermore National Laboratory (LLNL) scientists have found that atomic disorder in certain boron-based hydrogen storage systems can potentially improve the rate of hydrogen uptake. Metal boride surfaces and their single-layer variants — known as borophenes — are generally thought to feature a regular arrangement of atoms at low to moderate temperatures. The LLNL team proved...

Survivor salmon persist through drought and ocean warming

Nov. 2, 2021- 
In drought years and when marine heat waves warm the Pacific Ocean, the rare late-migrating juvenile spring-run Chinook salmon of California’s Central Valley are the survivors. They are among the few salmon that return to spawning rivers in those difficult years to keep their populations alive, according to results published today in Nature Climate Change. The trouble is that these...

LLNL team develops real-time diagnostic for Liquid Metal Jetting 3D printing

Nov. 1, 2021- 
As 3D printing continues to grow and evolve, diagnostics capable of monitoring builds in real-time have become essential tools for producing quality parts, particularly in emerging printing technologies such as Liquid Metal Jetting (LMJ). In LMJ, tiny molten metal droplets are ejected from a nozzle at high speeds to 3D print a part in layers, similar to inkjet printers on the consumer...

LLNL researchers garner three awards among top 100 industrial inventions

Oct. 29, 2021- 
Lawrence Livermore National Laboratory (LLNL) scientists and engineers have collected three awards among the top 100 industrial inventions worldwide. The trade journal R&D World Magazine announced the winners of the awards, often called the “Oscars of invention,” during a three-day virtual ceremony — Oct. 19-21 — and on the magazine’s website. With this year’s results, the Laboratory...

New hydrogen storage material steps on the gas

Oct. 28, 2021- 
Hydrogen is increasingly viewed as essential to a sustainable world energy economy because it can store surplus renewable power, decarbonize transportation and serve as a zero-emission energy carrier. However, conventional high-pressure or cryogenic storage pose significant technical and engineering challenges. To overcome these challenges, Lawrence Livermore National Laboratory (LLNL)...

Nuclear weapons technology for a new generation of policymakers

Oct. 27, 2021- 
Policymaking for nuclear security requires a strong grasp of the associated technical matters. That grasp came naturally in the early decades of the nuclear era, when scientists and engineers were deeply engaged in policymaking. Yet in the last few decades, the scientists and engineers who conceived, built and executed the programs that created the existing U.S. nuclear deterrent faded...

New research looks at process of magnetic flux generation in ICF implosions

Oct. 27, 2021- 
Lawrence Livermore National Laboratory (LLNL) researchers now have a better understanding on how strong the magnetic fields are in an inertial confinement fusion (ICF) implosion at the National Ignition Facility (NIF), the world’s most energetic laser. The researchers described their findings a paper published in Physics of Plasmas with LLNL scientists Chris Walsh serving as lead...

Tube-in-tube structure going strong

Oct. 26, 2021- 
Similar to grass stems, Lawrence Livermore National Laboratory (LLNL) scientists have created nanostrut-connected tube-in-tubes that enable stronger low-density structural materials.
