Molecular polarizability anisotropy of liquid water revealed by terahertz-induced transient orientation

The intermolecular dynamics of liquid water impact most biological processes. Here, the authors use intense terahertz electromagnetic pulses to generate a transient, out-of-equilibrium state of the water network to show that the molecules become oriented and probe the polarizability of this anisotropic state.

Capturing ultrafast molecular motions and lattice dynamics in spin crossover film using femtosecond diffraction methods

The spin crossover films provide an efficient control of material properties by light excitation. In this work, the authors reveal sequential photo-switching dynamics, from local molecular rearrangement to global lattice deformation.

Role of vacancies in metal–insulator transitions of crystalline phase-change materials

Phase-change materials show an unusual metal–insulator transition that is induced by disorder in the crystalline state. Numerical computations now show how the transition to the metallic state proceeds from the dissolution of electronic states situated at vacancy clusters to the formation of ordered vacancy layers.

A sensitive high repetition rate arrival time monitor for X-ray free electron lasers

In time-resolved measurements it is crucial to know the time delay between the exciting and probing light pulses. Here the authors demonstrate a self-referencing common-path interferometer method measuring the arrival time between the X-ray free electron laser and the optical pulse to the target and thus their inherent timing jitter.

Femtosecond X-ray emission study of the spin cross-over dynamics in haem proteins

The change from low-spin hexacoordinated to high-spin pentacoordinated domed form in heam upon ligand detachment and the reverse process underlie the respiratory function. The authors, using femtosecond time-resolved X-ray emission spectroscopy, capture the transient states connecting the two forms in myoglobin-NO upon NO photoinduced detachment.
