PACIFICHEM: CTH005: Computational Photocatalysis — Computational Photocatalysis: Photophysics & Photochemistry at Interfaces. Machine Learning Bridges Theory and Experiment
15 dec 2025 - 20 dec 2025 • Honolulu, États-Unis
Résumé:
The study of photochemical reactions in general and photoelectrochemical water splitting in particular, rests on understanding of such elementary effects as light absorption, energy transfer, electron transfer, radiative and nonradiative relaxation, and catalysis is important for the rational design of efficient systems for energy conversion. The design of most efficient catalysts is pursued by change of composition, quantum confinement, size, shape, surface functionalization, magnetic doping, and mesoscale structural arrangement providing versatile tuning of timescales of available basic mechanisms and properties of materials. This symposium presents recent experimental, computational, and machine learning synergistic advances on modeling of photophysics and photochemistry at interfaces: Experimental achievements in fabrication of efficient photocatalytic interfaces and monitoring of efficiency, quantum yield, and kinetics of reactant evolution and electronic dynamics by ultrafast spectroscopy techniques stimulate further development of more precise theoretical methods. Computational modeling allows for interpretation of available experimental trends and help in guiding further advances in design of efficient photocatalytic materials.

Cheminformatics and machine learning advances help to establish a feedback loop between computation and experiment and narrow down the number of structures with high potential for record efficiency. It is expected that the symposium will bring better understanding of photoinduced processes of light absorption, formation and breaking of charge transfer excitations, hot carrier relaxation, multiple exciton processes, coupled light-to-matter states, and redox reaction dynamics at catalytic sites, affected by lattice vibrations and solvent polarization.

ELIXIR 2026 — L’atelier thématique ELIXIR2026 / ELIXIR2026 workshop
09 mar 2026 - 11 mar 2026 • Saint Aubin, France
Organisateur:
Synchrotron SOLEIL
Résumé:
The development of vacuum-compatible liquid sampling sources has enabled the use of ionizing radiation sources (XUV and X-rays) to study reaction dynamics in solution. This development is constantly evolving with improvements in light sources, such as the relative democratization of laser sources based on high-order harmonic generation, and improvements in liquid targets with the recent development of stable flat liquid jets with sub-micrometer thicknesses. The transvers nature of reaction dynamics in water across different scientific communities means that the spectroscopic tools available are extremely varied. These include time-resolved photoemission spectroscopy (femtosecond and even attosecond), highly nonlinear optics via liquid-phase HHG, chiral linear probe development (circular X-ray dichroism, PECD), RIXS, coincidence measurement (e-,e-), etc. This workshop will bring together users of these different tools. It will also provide an opportunity to compare and improve theoretical aspects of molecular dynamics in the liquid phase, thanks to the participation, we hope, of European experts in the field.
