Clusters show a strong size-dependence of their chemical properties. An example is the high catalytic activity of small Au clusters deposited on different substrates. However, any interaction with a substrate alters their properties. To understand the origin of the size dependency, data on free clusters are needed. These could be valence band photoelectron spectra of reacted clusters. In such...

4. Quantum State-Resolved Studies of Gas/Surface Reaction Dynamics by Vibrational Spectroscopies

Methane dissociation is the rate limiting step in the steam reforming process used by the chemical industry to convert natural gas into a mixture of H$_2$ and CO known as synthesis gas. To better understand the microscopic mechanism and reaction dynamics of methane chemisorption, we use vibrational spectroscopies and infrared lasers for quantum state-resolved studies of methane dissociation...

24. Interfacial Energy and Charge Transfer Dynamics studied by Time-Resolved X-ray Photoelectron Spectroscopy

Dr Oliver Gessner (Lawrence Berkeley National Laboratory)

The success of many emerging molecular electronics concepts hinges on an atomistic understanding of the underlying electronic dynamics. Processes evolving on spatial and temporal scales spanning orders of magnitude have to be connected in order to gain a comprehensive understanding of the fundamental dynamics and scaling laws that enable molecular, interfacial, and macroscopic charge and...

37. Role of catalyst support in hydrogen spillover

Prof. Jeroen van Bokhoven (ETH Zurich and PSI)

Catalysis is the workhorse in chemicals production, energy conversion and pollution abatement. There is a continued demand for novel materials and processes and such development is greatly helped by understanding the fundamental steps in the catalytic process. Catalysts are often nano-sized particle anchored to a support, the role of which in the catalytic process often remains unclear. By...

5. Surface scattering at extreme ultra-violet (XUV) free electron lasers

Dr Bastian Christopher Krüger (Max Planck Institute for Biophysical Chemistry)

The “Mobile Beamer surface scattering machine” is designed to make use of the advantageous properties of the radiation produced by the XUV free electron laser in Dalian[1] for surface scattering experiments on atoms and molecules. The XUV photolysis of small molecules will be used as a novel source of atomic beams, providing fine control over the electronic state and kinetic energy. In...
