Abstract

Nanoparticles as smallest portions of bulk material, form the basis for a whole range of new technologies. Due to the laws of quantum mechanics, such particles measuring only up to a few nanometers can behave completely different in terms of conductivity, optics or robustness than the same material on a macroscopic scale. In applications such as catalysis and sensorics, nanoparticles offer great advantages due to their large effective surface area compared to their volume. The development of synthesis methods with control over the composition, size and atomic structure of nanoparticles will be a key to prepare the desired materials. Several synthesis routes have been developed over the past years, from physical routes to fabricate well-defined ligand-free model catalysts by e.g. laser ablation or sputtering and helium droplet assisted aggregation of atoms or molecules of interest to chemical routes employing precursor molecules in solution yielding so-called ligand stabilized clusters, ultimately for the deposition of individual particles on model and technologically relevant supports. The created samples are typically studied by electron microscopies, X-ray spectroscopies, X-ray diffraction and scattering, electron energy loss spectroscopy, or photoemission electron microscopy. The proposed mini-colloquium will present lectures covering different aspects of the topic, both experimental and theoretical.
