MPI Campus Seminar: Structural insights into major design principles of the human spliceosome
Without adsorption, heterogeneous catalysis is not possible. A reactant adsorbs only if it transfers enough kinetic energy to the solid[1]; yet we still lack of a clear picture for the energy transfer mechanism between molecules and surfaces. Recently, detailed theoretical and experimental investigations of energy transfer between hydrogen atoms and late fcc transition metal (111) surfaces have been made and on the basis of these experiments, it was possible to clarify the role of electron-hole pair excitation during the scattering process.[2-5] However, the influence of the surface structure on the scattering dynamics has not been investigated yet. In this talk, I present my efforts to adapt the technique used in the above mentioned studies onto other metal surface geometries. Therefore, I firstly checked, if the potential energy surface (PES) for H at Ag(111) from Kammler et.al.[4] reproduces the energies for H at Ag(100) and Ag(110) without changing the parameterisation. Subsequently, I performed molecular dynamics simulations from those three different silver surfaces to check whether the surface geometry has an significant influence on the scattering dynamics or not by comparing angular distributions and final energies of the scattered projectiles.
