Abstract Among nanoalloys, Co–Pt type (CoPt or FePt) supported nanostructures are very
interesting systems due to the direct link between atom arrangement and magnetic behavior …

The loss of electrochemical active surface area (ECSA) at the cathode is one of the main
causes of performance degradation in Polymer Electrolyte Membrane Fuel Cells (PEMFCs) …

We report the synthesis and characterization of well-defined CoPt clusters with a mean
diameter of 3 nm, produced in ultrahigh vacuum conditions following a physical route …

The structure and chemical ordering of CoPt nanoclusters in the size range of 1 to 3 nm are
investigated by global optimization methods and Monte Carlo simulations using a many …

We present an upgrade of the available measurement techniques at the wiggler beamline
BW4 of the Hamburger Synchrotronstrahlungslabor (HASYLAB) to grazing incidence wide …

Functional cluster-assembled nanostructures with original structures and properties are
prepared using the Low Energy Cluster Beam Deposition method (LECBD). This technique …

The structure and morphology of 1 to 3 nm size CoPt nanoparticles have been investigated
