Spectroscopy and Chemistry of Metal Clusters and Cluster Complexes
11. July 2014: We have a new Doktor! Congratulations, Alex!
Angewandte Chemie: We report on the unexpected activation of molecular oxygen by cationic gold clusters and the formation of superoxo species.
March 2014: Invited Concept article in Chemistry - A European Journal: Platinum group metal clusters: from gas-phase structures and reactivities towards model catalysts
15. Nov 2013: Christian successfully defended his PhD at the University of Nijmegen. Congratulations!
Nov 2013: We have performed the first experiments with the new IR-FEL at the Fritz-Haber-Institut der MPG.
Communication in J. Chem. Phys.: We unravel the structures of small platinum clusters. Pt4+ and Pt5+' already favor three-dimensional geometries, in contrast to a number of earlier predictions.
Angewandte Chemie: We investigate the activation of O2 by anionic gold clusters and unambiguously show the formation of superoxo (O2-) species on clusters containing an even number of Au atoms.
Tubes but no cubes: Small neutral MgO clusters tend to form six-ring based structures, but the cubic bulk motif is unfavorable.
In a Communication in Angewandte Chemie we report on the initial stage of methane activation on small platinum clusters.
We demonstrate a new method for determining vibrational spectra of anionic metal clusters: infrared resonance enhanced multiple photon electron detachment (IR-REMPED), where the cluster beam interacts with the IR radiation inside the cavity of FELICE, the new Free Electron Laser for IntraCavity Experiments at the FELIX facility.
See here for our results on the structures of neutral gold clusters which have been published in Science.
