Graphite enters different states of matter in ultrafast experiment

Graphite enters different states of matter in ultrafast experiment - For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds. Using the Linac Coherent Light Source X-ray Free-Electron Laser at SLAC National Accelerator Laboratory at Stanford, Stefan Hau-Riege of Lawrence Livermore National Laboratory and colleagues heated graphite to induce a transition from solid to liquid and to warm-dense plasma. The research is scheduled to appear in the May 21 edition Physical Review Letters.
