LLNL and University of Nevada, Las Vegas scientists report a previously unknown pressure-induced phase transformation in TATB above 4 GPa (40,000 atmospheres of pressure). Image by Adam Connell/TID

An unexpected phase transition in the high explosive TATB

Determining the unreacted equation of state of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) is challenging because it exhibits low crystal symmetry and low X-ray scattering strength. The causes of...
In this artistic rendering of the laser compression experiment, high power lasers focus on the surface of a diamond, generating a sequence of shock waves that propagate throughout the sample assembly (from left to right), simultaneously compressing and heating the initially liquid water sample, forcing it to freeze into the superionic water ice phase.

Revealing the atomic structure of superionic ice

Using giant lasers, scientists at the Lawrence Livermore National Laboratory (LLNL) produced wild new kind of ice that is expected to exist inside the...
