Metal deposits on well-ordered oxide films
TL;DR: In this paper, the authors discuss the possibility to use thin, well-ordered oxide films as supports for the study of deposited metal particles, which offers the advantage to permit the unrestricted application of all experimental methods, which rely on a good electrical or thermal conductivity of the sample, like PES, LEED, STM or TDS.

Core-level binding-energy shifts at surfaces and in solids
TL;DR: A review of core-level binding energy shifts observed in photoelectron spectroscopy can be found in this paper, where the authors focus on shifts since most of the chemical and physical insights provided by core levels are derived not from the core energies themselves but from shifts they exhibit.

Clusters and islands on oxides: from catalysis via electronics and magnetism to optics
TL;DR: The state of the art of the field is reviewed on the basis of examples from various research groups in this article, and a series of new experiments that could be undertaken to answer some key questions in the field are discussed.

Catalysis by Alloys in Hydrocarbon Reactions
TL;DR: The effect of alloying on catalytic reactions depends very much on the mechanism of the catalytic reaction and on the type of intermediates operating upon reaction as mentioned in this paper, and the alloying effect is very pronounced if in order for a reaction to occur, large ensembles of certain metal atoms are required.

Modeling heterogeneous catalysts: metal clusters on planar oxide supports
TL;DR: In this paper, the properties of nanosized supported metal clusters were investigated using low-energy ion scattering spectroscopy (LEIS), temperature-programmed desorption (TPD), X-ray photoelectron spectrograph (XPS) and scanning tunneling microscopy (STM) and spectroscopic (STS) with emphasis on the unique properties of clusters <5.0 nm in size.

Electronic Structure of Catalytic Metal Clusters Studied by X-Ray Photoemission Spectroscopy.
TL;DR: Pd and Pt clusters on carbon substrates have been studied by x-ray photoemission spectroscopy (XPS) as mentioned in this paper, showing that single-atom centers appear to exist in the ${d}^{9}{s}^{1}$ configuration, and there is a correlation between $d$-orbital occupation and catalytic activity in electroless nickel deposition.

Calculated Properties of Metal Aggregates. II. Silver and Palladium
TL;DR: Extended Huckel and CNDO calculations have been made for Ag and Pd aggregates as mentioned in this paper, and the I.P. and E.A. in both types of geometry converge to a common value at 20 atoms in Ag and at 4 atoms in Pd.

Vapor deposition of silver, gold and palladium on carbon and silicon dioxide in ion-pumped vacuum
J.F. Hamilton,P.C. Logel +1 more
TL;DR: In this paper, the analysis of low coverage deposits is accomplished by extrapolation of nucleus density and mean size data from higher coverage deposits, and from counts on zinc-amplified nuclei at low coverage.

Calculated properties of metal aggregates: III. Carbon substrates
TL;DR: In this paper, the energy levels of the adsorbed aggregate were investigated and it was shown that the substrate may have a pronounced effect on the energy level of the aggregate and this effect can change the catalytic properties of metal aggregates.
