The advent of femtosecond lasers has shed new light on non-equilibrium high energy
density physics. The ultrafast energy absorption by electrons and the finite rate of their …

The European Synchrotron Radiation Facility has recently made available to the user
community a facility totally dedicated to Time-resolved and Extreme-conditions X-ray …

As the main constituent of planetary cores, pure iron phase diagram under high pressure
and temperature is of fundamental importance in geophysics and planetary science …

The Inner Shell Spectroscopy (ISS) beamline on the 8-ID station at the National Synchrotron
Light Source II (NSLS-II), Upton, NY, USA, is a high-throughput X-ray absorption …

Temperature, thermal history, and dynamics of Earth rely critically on the knowledge of the
melting temperature of iron at the pressure conditions of the inner core boundary (ICB) …

Taking advantage of the new opportunities provided by x-ray free electron laser (FEL)

Transition metal nanoparticles (NPs) are promising materials for use as catalysts in many
processes, although they are easily oxidized under ambient conditions. In this …

Metallic copper generally adopts an FCC structure. In this work, we detect highly unusual
BCC-structured Cu nanoparticles as a transient intermediate during the H2 reduction of a …
