Researchers discover cause of radiation defects

Jun. 1, 2018 -  
A team of scientists from Lawrence Livermore National Laboratory ( LLNL ) and Texas A&M University got a step closer to understanding radiation damage phenomena. They found that the density of collision cascades has a profound effect on defect interaction dynamics in silicon. The team...

LLNL-led team expands forensic method to identify people using proteins from bones

May. 21, 2018 -  
When a team of researchers led by Lawrence Livermore National Laboratory (LLNL) developed a new biological identification method that exploits information encoded in proteins, they thought it could have multiple applications. Nearly two years later, they’ve turned out to be right. In September 2016...

PROSPECTing for antineutrinos

May. 18, 2018 -  
The Precision Reactor Oscillation and Spectrum Experiment ( PROSPECT ) has completed installation of a novel antineutrino detector that will probe the possible existence of a new form of matter -- sterile neutrinos. PROSPECT, located at the High Flux Isotope Reactor ( HFIR ) at the Department of...

A warm look at water’s structure

May. 14, 2018 -  
Boiling water traditionally involves adding energy to molecules by conduction, convection or thermal radiation. But Lawrence Livermore National Laboratory ( LLNL ) scientists and collaborators have figured out a way using an X-ray Free Electron Laser (XFEL) to heat water to temperatures above 100,...

Lab research in fuels, engines in the spotlight

May. 3, 2018 -  
The Department of Energy’s ( DOE ) Co-Optimization of Fuels & Engines ( Co-Optima ) initiative recently highlighted the work that Lawrence Livermore National Laboratory ( LLNL ) scientists have performed on models of high-performance fuels to see how they would perform in advanced internal...

Additive manufacturing advances K-9 training

Apr. 26, 2018 -  
Additive manufacturing (AM) has gone to the dogs, thanks to Lawrence Livermore National Laboratory’s ( LLNL ’s) new approach to K-9 training materials. The process prints 3D objects that contain trace amounts of nonreactive explosives, resulting in several advantages for K-9s and their handlers...

Record experiments probe exoplanetary cores

Apr. 25, 2018 -  
Using high-powered laser beams, iron-silicon alloys have been compressed to unprecedented pressures corresponding to the center of a three-Earth-mass extrasolar planet. The resulting measurements of crystal structure and density provide new insights into the nature of the deep interiors of the...

Americans ramp up use of solar, wind energy

Apr. 24, 2018 -  
Americans used more solar and wind energy in 2017 compared to the previous year, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory (LLNL). Overall, energy consumption by the residential and commercial sectors dropped a bit. Each year, the Laboratory...

New exascale system for earth simulation

Apr. 23, 2018 -  
A new earth modeling system unveiled today will have weather-scale resolution and use advanced computers to simulate aspects of Earth’s variability and anticipate decadal changes that will critically impact the U.S. energy sector in coming years. After four years of development, the Energy Exascale...

LLNL maps out deployment of carbon capture and sequestration for ethanol production

Apr. 23, 2018 -  
To better understand the near-term commercial potential for capturing and storing atmospheric carbon dioxide (CO 2 ), researchers from Lawrence Livermore National Laboratory ( LLNL ) have mapped out how CO 2 might be captured from existing U.S. ethanol biorefineries and permanently stored (or...
