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 …

Piezoelectricity describes interconversion between electrical charge and mechanical strain.
As expected for lattice ions displaced in an electric field, the proportionality constant is …

Crucial to many light-driven processes in transition metal complexes is the absorption and
dissipation of energy by 3 d electrons,,,. But a detailed understanding of such non …

The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

The non-equilibrium dynamics of electrons and nuclei govern the function of photoactive
materials. Disentangling these dynamics remains a critical goal for understanding …

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 …

Light-driven molecular reactions are dictated by the excited state potential energy
landscape, depending critically on the location of conical intersections and intersystem …

Strongly σ‐donating N‐heterocyclic carbenes (NHCs) have revived research interest in the
catalytic chemistry of iron, and are now also starting to bring the photochemistry and …
