Electrons are the workhorses of solar energy conversion. Conversion of the energy of light to
electricity in photovoltaics, or to energy-rich molecules (solar fuel) through photocatalytic …

We review the tremendous advances in ultrafast X-ray science, over the past 15 years,
making the best use of new ultrashort X-ray sources including table-top or large-scale …

Time-resolved x-ray absorption spectroscopy (TR-XAS) has so far practically been limited to
large-scale facilities, to subpicosecond temporal resolution, and to the condensed phase …

We report that silicon surfaces develop an array of sharp conical spikes when irradiated with
500 laser pulses of 100-fs duration, 10-kJ/m2 fluence in 500-Torr SF6 or Cl2. The spikes are …

X-ray absorption spectroscopy is a powerful probe of molecular structure, but it has
previously been too slow to track the earliest dynamics after photoexcitation. We …

▪ Abstract In this review, we highlight the progress made in the development of 4D ultrafast
electron diffraction (UED), crystallography (UEC), and microscopy (UEM) with a focus on …

The development of femtosecond lasers brought entirely new possibilities into the practice of
timeresolved spectroscopy, for both UV-vis and IR-Raman spectroscopies. In addition, it has …

Momentum angular distributions of the nonlinear multiphoton photoelectron spectra from
intense ultrashort pulse ionization of H2+ molecular ions show signatures of electron …

The extension of time-resolved X-ray diffraction to the subpicosecond domain is an
important challenge, as the nature of chemical reactions and phase transitions is determined …

Capturing the evolving geometric and electronic structure in the course of a chemical
reaction or biological process is the principal aim of time-resolved X-ray spectroscopies …
