Modeling neuronal cultures on 'brain-on-a-chip' devices

For the past several years, Lawrence Livermore National Laboratory (LLNL) scientists and engineers have made significant progress in development of a three-dimensional "brain-on-a-chip" device capable of recording neural ...

Checking out iron under pressure

Iron is the most stable and heaviest chemical element produced by nucleosynthesis in stars, making it the most abundant heavy element in the universe and in the interiors of Earth and other rocky planets.

Work resumes in support of stockpile modernization

The effort to resume hands-on work in support of stockpile modernization programs reached a major milestone May 7 with the successful execution of a focused experiment at the High Explosives Applications Facility (HEAF) at ...

Pinpointing the effects of nanoconfinement on water

Researchers have spent decades studying the properties of water and how they change when there are disruptions to their normal behavior. Research on the topic has a wide range of applications, from biochemical systems to ...

Simulations explain detonation properties in TATB

Two Lawrence Livermore National Laboratory (LLNL) scientists have discovered a new mechanism for ignition of high explosives that explains the unusual detonation properties of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB).

Membrane nanopore transport gets picky

Trying to determine how negatively charged ions squeeze through a carbon nanotube 20,000 times smaller than a human hair is no easy feat.

Second skin protects against chemical, biological agents

Recent events such as the COVID-19 pandemic and the use of chemical weapons in the Syria conflict have provided a stark reminder of the plethora of chemical and biological threats that soldiers, medical personnel and first ...
