Unveiling a novel sample configuration for ultrahigh pressure equation of state calibrations

In a paper published recently in the Journal of Applied Physics as an Editors Pick, an international team of scientists from Lawrence Livermore National Laboratory (LLNL), Argonne National Laboratory and Deutsches Elektronen-Synchrotron have developed a new sample configuration that improves the reliability of equation of state measurements in a pressure regime not…

Magnesium oxide undergoes dynamic transition when it comes to super-Earth exoplanets

Researchers from Lawrence Livermore National Laboratory (LLNL) and Johns Hopkins University have unlocked new secrets about the interiors of super-Earth exoplanets, potentially revolutionizing our understanding of these distant worlds. The focus of this work, magnesium oxide (MgO), a crucial component of Earth’s lower mantle, is believed to play a similar role in the…
