Cr and rare-earth grey phases form in doped fuel models
Synchrotron spectroscopy reveals chromium and lanthanide speciation in Cr-doped uranium dioxide fuels, showing perovskite secondary phases remain structurally stable under radiation exposure.

Approximate shock models fail at sufficiently high velocities
Numerical model reveals that simplified approximations for synchrotron emission from relativistic shocks can be inaccurate by over an order of magnitude, biasing inferred properties of transients.
