Gold remains in a crystalline structure even when heated to 14 times its melting point.

The United States Department of Energy's SLAC National Accelerator Laboratory, in collaboration with teams from multiple countries, used ultrafast laser heating technology to heat gold to more than 14 times its melting point while still maintaining its crystal structure, overturning the long-standing theory of "entropy burst". This research achieved, for the first time, the direct measurement of atomic temperatures in extremely high-temperature materials, overturning traditional understanding of superheating phenomena in matter. The related findings were published in the latest issue of the journal Nature.
