  • The European X-ray FreeElectron Laser Facility generates ultrashort hard X-ray pulses with megahertz repetition rate. Here, the authors probe the dynamics of dense antibody protein (Ig-PEG) solutions using megahertz X-ray photon correlation spectroscopy at the European XFEL.

  • The phase transition between water and ice is a ubiquitous phenomenon in nature. Here, the authors conduct a time-resolved x-ray scattering experiment using X-ray Free Electron Lasers to elucidate a comprehensive picture of the melting and recrystallization dynamics of crystalline ice, based on direct structural information.

  • Obtaining experimental evidence of a liquid-liquid phase transition in supercooled water is challenging due to the rapid crystallization. Here the authors drive low-density amorphous ice to the conditions of liquid-liquid coexistence using ultrafast laser heating and observe the liquid-liquid phase transition with femtosecond x-ray laser pulses.

  • Supercooled water is expected to undergo two glass transitions, but their experimental observation is technically challenging. Here, the authors demonstrate the application of X-ray photon correlation spectroscopy at elevated pressure to tackle this problem and observe a glass transition in high-density amorphous ice at around 0.08 ± 0.02 GPa that occurs at higher temperatures compared to ambient conditions.
