Our next seminar is with Dr Matt Watkins, Reader at the School of Mathematics and Physics, at The University of Lincoln.

The talk is entitled 'Modelling Optical Properties at Interfaces of Materials'

Characterising solvated surfaces is difficult. Optical and electronic processes are at the heart of many sensing and catalytic processes at these solid/liquid interfaces, but are hard to include in current ab initio simulations.
I will describe recent work:
• with scanning probe groups to identify the molecular structure of solvated surfaces [1].
• discuss our work to extending the models available in the CP2K simulation package to allow charge transport and optical processes to be included [2].
• provide examples of calculations ‘illuminating’ photo driven processes on surfaces [2,3].
