As it is known from visible light experiments, silicon under femtosecond pulse irradiation can undergo the so-called ’nonthermal melting’ if the density of electrons excited from the valence to the conduction band overcomes a certain critical value. Such ultrafast transition is induced by strong changes in the atomic potential energy surface, which trigger atomic relocation. However, heating of a material due to the electron-phonon coupling can also lead to a phase transition, called ’thermal… 

Thermal and nonthermal melting of silicon exposed to femtosecond pulses of x-ray irradiation

Silicon irradiated with an ultrashort laser pulse can experience two competing damage processes: the ultrafast ’nonthermal melting’ or the picoseconds ‘thermal melting’. The first one occurs if the

Various damage mechanisms in carbon and silicon materials under femtosecond X-ray irradiation

We review the results of our research on damage mechanisms in materials irradiated with femtosecond free-electron-laser (FEL) pulses. They were obtained using our hybrid approach, X-ray-induced

Femtosecond phase-transition in hard x-ray excited bismuth

TLDR
This first-time observation of a hard x-ray induced ultrafast phase transition in a bismuth single crystal at high intensities indicates a nonthermal origin of a lattice disordering process, and excludes interpretations based on electron-ion equilibration process, or on thermodynamic heating process leading to plasma formation.

Damage threshold in pre-heated materials exposed to intense X-rays

Materials exposed to ultrashort intense x-ray irradiation may experience various damaging conditions depending on the in-situ temperature. A pre-heated target exposed to intense x-rays plays a

Ultrafast nonthermal heating of water initiated by an X-ray Free-Electron Laser

TLDR
The bright ultrafast pulses of X-ray Free-Electron Lasers allow investigation into the structure of matter under extreme conditions, and single pulses to ionize and probe water as it undergoes a phase transition from liquid to plasma.

TLDR
Data is reported here to show that a purified particulate preparation from heart muscle which contains all the components of the cytochrome electron transmitter system also contains transhydrogenase, and no reaction whatsoever occurs with TPNH, whether added as such or generated by the glucose-6-phosphate dehydrogenase system.
