154. Towards femtochemistry X-ray studies of catalysis on surfaces under operando

Martin Beye

6/26/25, 11:10 AM

Invited talk

Catalytic processes on surfaces are ubiquitous and a profound understanding has become even more important in order to support the energy transition: virtually every process that can convert carbondioxide into fuels and even the production of alternative energy carriers, like hydrogen or ammonia, involves processes on surfaces. In order to rapidly tailor optimal catalysts that respect the new...

113. Phonon Transport and Polaron Formation with Mode, Momentum and Time Resolution using Ultrafast Electron Diffuse Scattering (UEDS)

Prof. Bradley Siwick (Department of Physics and Department of Chemistry, Center for the Physics of Materials (CPM), McGill University, Montreal, Canada)

6/26/25, 11:40 AM

Contributed talk

The nature of the couplings within and between lattice and charge degrees of freedom is central our understanding of material properties. These interactions are essential to phenomena as diverse as thermoelectricity, superconductivity, charge density waves, and carrier and phonon transport. Despite their fundamental role in a broad range of processes, detailed momentum-dependent information on...

14. Applications of optical crystallography to ultrafast X-ray crystallography for structural dynamics.

Jasper van Thor (Imperial College London)

6/26/25, 12:00 PM

Contributed talk

Ultrafast X-ray crystallography has emerged as a powerful technique to resolve electron density dynamics on femtosecond time scale in molecular crystals, using X-ray Free Electron Lasers. However, a multitude of ultrafast phenomena, in particular optical non-linear processes, remain to be fully established for this application. There are multiple avenues to combine the techniques of optical...

26. Probing Ultrafast Photoinduced Structural Dynamics in Molecular Solutions using Angular X-ray Cross-Correlation Analysis

Ruslan Kurta (European XFEL)

6/26/25, 12:20 PM

Contributed talk

Understanding photoinduced chemical reactions at the electronic, atomic and molecular scales and on relevant timescales is critical for controlling reaction pathways, rates and efficiency. This fundamental knowledge is essential for applications such as catalysis, photoswitching, and light-harvesting. X-ray free-electron lasers (XFELs) produce intense and ultrashort x-ray pulses, allowing to...
