Lab scientists optimizing high performance fuels for advanced internal combustion engines

Mar. 20, 2018 -  
In support of the Department of Energy’s ( DOE ) Co-Optimization of Fuels & Engines (Co-Optima) initiative, Lawrence Livermore National Laboratory ( LLNL ) scientists are developing models of high performance fuels to see how they would perform in advanced internal combustion engines. The DOE...

Lab scientists to improve energy efficiency of copper catalysts that convert CO2 to methane

Mar. 8, 2018 -  
Lawrence Livermore National Laboratory (LLNL) researchers have received $1 million from the Department of Energy to improve the energy efficiency of copper-based catalysts to convert carbon dioxide into methane and other valuable hydrocarbon products. Led by LLNL’s Juergen Biener, the project will...

Lab employee and retiree named fellows

Mar. 2, 2018 -  
Two researchers affiliated with Lawrence Livermore National Laboratory (LLNL) -- a current employee and a retiree -- have been named fellows of the international Combustion Institute (CI). Bill Pitz, a combustion scientist in the Lab’s Materials Science Division, and Charlie Westbrook, a retired...

Earth’s core metals react well to electrons

Mar. 1, 2018 -  
At temperatures and pressures found on Earth’s surface, metallic elements are electropositive and lose their valence electrons to form positively charged cations. Metals have free electrons that naturally form compounds with electronegative elements. For example, iron reacts with oxygen to form...

Scientists find 'frustration' in battery materials

Feb. 22, 2018 -  
Adding carbon atoms to a new type of solid lithium ion battery could make it charge faster and more safely. Solid-state lithium-ion batteries can provide dramatically improved safety, voltage and energy density compared with today’s batteries, which use liquid components. They could be used in...

Drones deliver green transportation option

Feb. 13, 2018 -  
By getting your next package delivered by drone, you could be saving energy, but only if companies deploy drones sensibly. New research by Lawrence Livermore National Laboratory ( LLNL ), Carnegie Mellon University , SRI International and the University of Colorado at Boulder shows that drone-based...

Protein that prevents further cartilage damage

Feb. 12, 2018 -  
There may be a protein in the body that hinders cartilage degradation in patients with a torn anterior cruciate ligament (ACL). Lawrence Livermore National Laboratory ( LLNL ) scientists performed in vivo experiments on animal models of post traumatic osteoarthritis and found that sclerostin (a...

Hayward fault earthquake simulations increase fidelity of ground motions

Feb. 8, 2018 -  
In the next 30 years, there is a one-in-three chance that the Hayward fault will rupture with a 6.7 magnitude or higher earthquake, according to the U nited States Geologic Survey (USGS). Such an earthquake will cause widespread damage to structures, transportation and utilities, as well as...

First experimental evidence for superionic ice

Feb. 5, 2018 -  
Among the many discoveries on matter at high pressure that garnered him the Nobel Prize in 1946, scientist Percy Bridgman discovered five different crystalline forms of water ice, ushering in more than 100 years of research into how ice behaves under extreme conditions. One of the most intriguing...

Researchers characterize membrane behavior

Feb. 2, 2018 -  
An article authored by a team of Lawrence Livermore National Laboratory ( LLNL ) scientists has characterized how different cell membranes behave. “Different membranes in different parts of the body have different barrier strengths that are required for drugs to penetrate them to reach the organ,”...
