Exascale in motion on earthquake risks

Oct. 12, 2017 -  
Assessing large magnitude (greater than 6 on the Richter scale) earthquake hazards on a regional (up to 100 kilometers) scale takes big machines. To resolve the frequencies important to engineering analysis of the built environment (up to 10 Hz or higher), numerical simulations of earthquake...

Big, bad, Martian volcanoes unveiled

Oct. 10, 2017 -  
They are bigger, scarier and last longer. That’s the conclusion of a team of scientists, including Lawrence Livermore National Laboratory cosmochemist Bill Cassata, about the evolution of volcanoes on the red planet, compared to those on Earth. Martian volcanoes are the largest in the solar system...

LLNL scientists stick to a new efficient magnet

Oct. 9, 2017 -  
Lawrence Livermore National Laboratory researchers have developed a new, more efficient permanent magnet that removes the deficiencies of conventional samarium and neodymium magnets. The proposed magnet stems from the well-known samarium and cobalt (SmCo 5 , CaCu 5 -type structure) magnet, but goes...

New ultralight silver nanowire aerogel is boon for energy and electronics industries

Oct. 5, 2017 -  
A new ultralight silver nanowire aerogel could be a boost to the energy and electronics industries. Metal foams (or porous metals) represent a new class of materials with unique properties including lightweight, high surface area, high electrical conductivity and low thermal conductivity. Lawrence...

Scientists estimate death rates from air pollution caused by the impact of climate change

Oct. 3, 2017 -  
A recent study by Lawrence Livermore National Laboratory (LLNL) scientists and collaborators is the first to use an ensemble of global chemistry climate models to estimate death rates from air pollution caused by the impact of climate change on pollutant concentrations. Ground-level ozone and fine...

Atomic-scale simulations go the distance to resolve the 'jiggle, wiggle' of metal strength

Sep. 27, 2017 -  
Lawrence Livermore National Laboratory ( LLNL ) researchers have dived down to the atomic scale to resolve every “jiggle and wiggle” of atomic motion that underlies metal strength. In a first-of-its-kind series of computer simulations focused on metal tantalum, the team predicted that, on reaching...

LLNL researchers to study soil microbiome

Sep. 26, 2017 -  
A new Lawrence Livermore National Laboratory ( LLNL ) initiative to study how the soil microbiome (microorganisms such as fungi and bacteria, microfauna and viruses) controls the mechanisms that regulate organic matter stabilization in soil can move forward after the Department of Energy’s (DOE)...

A solid pathway toward hydrogen storage

Sep. 25, 2017 -  
An inexpensive and useful layered superconductor compound also may be an efficient solid-state material for storing hydrogen. The Department of Energy's (DOE) Energy Materials Network (EMN) consortium approach to accelerate material discovery and development is starting to pay off. Through theory...

Lab wins six DOE commercialization grants

Sep. 14, 2017 -  
For two years running, Lab researchers have exceeded expectations for capturing Department of Energy (DOE) Technology Commercialization Fund (TCF) grants. In 2016, the first year of the TCF competition, Rich Rankin, the head of the Lab’s Innovation and Partnerships Office (IPO), expected LLNL might...

Lab researchers achieve '4D printed' material

Sep. 13, 2017 -  
For the first time, Lawrence Livermore National Laboratory ( LLNL ) researchers have successfully 3D printed composite silicone materials that are flexible, stretchable and possess shape memory behavior, a discovery that could be used to create form-fitting cushioning activated by body heat, such...
