LLNL researchers an collaborators conduct a study that represents the first example of using X-ray diffraction to make direct time-resolved measurements of an aluminum sample’s ablation depth. 

Running on the second-generation Cerebras WSE-2 — a cutting-edge processor boasting 850,000 cores — the team from Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories and Cerebras Systems demonstrated the chip can perform complex simulations involving hundreds of thousands of atoms at speeds previously thought unattainable. The work is a finalist for the 2024 Association for Computing Machinery Gordon Bell Prize. the highest honor in supercomputing.

LLNL certified health physicist Brooke Buddemeier has been appointed to a panel of the National Academies of Sciences, Engineering and Medicine. 

Using atomic-resolution scanning transmission electron microscopy, researchers found that in the presence of iron, the grain boundary of titanium undergoes a phase transition, forming “cages” or “clusters” at the grain boundary (the gold region at the center of the image).
// S&T Highlights

LLNL researchers and international collaborators provide the first demonstration of how iron atoms, when introduced into titanium, undergo a GB transition.

American energy use is trending towards decarbonization, according to the most recent energy and carbon flow charts produced by Lawrence Livermore National Laboratory.
// S&T Highlights

LLNL releases annual flowcharts to illustrate the nation's consumption and uses of energy, as well as associated CO2 emissions.
