A New QCD facility at the M2 beam line of the CERN SPS: COMPASS++/AMBER

In this Letter of Intent, we propose a broad experimental programme for the ``New QCD facility at the M2 beam line of the CERN SPS''. This unrivalled installation will provide the site for a great variety of measurements to address fundamental issues of Quantum Chromodynamics, which are expected to lead to significant improvements in the understanding of QCD as our present theory of strong interactions. The proposed measurements cover the range from lowest-$Q^2$ physics as the determination of the proton radius by elastic muon-proton scattering, over average-$Q^2$-reactions to study hadron spectroscopy, to high-$Q^2$ hadron-structure investigations using the Drell-Yan process and Deeply Virtual Compton Scattering

chapter 10 Thin oxide films as model systems for heterogeneous catalysts

This chapter summarizes efforts to use thin oxide films as model supports for heterogeneous catalysts. We demonstrate that the oxide film route provides a useful platform to study oxide surfaces, per se its interaction with species from the gas phase, supported metal and oxide nanoparticles using the entire tool box of surfaces science under ultrahigh vacuum conditions. The extension to use thin oxide films as template also under ambient conditions or under water, is discussed and the potential to use oxide films as genuine two-dimensional materials is exemplified with vitreous and crystalline silica films
