The cover picture shows an ordered array of 400 palladium clusters deposited onto a gold single-crystal surface in sulfuric acid solution (courtesy of F. Simeone and D. M. Kolb). This image (200 nm×200 nm, average cluster height around 1 nm) was not only recorded in situ by scanning tunneling microscopy, the palladium clusters were also fabricated with the tip of the microscope. The Minireview by Kibler on page 985 addresses relations between the local surface structure of noble metal surfaces and their activity for the hydrogen evolution reaction. Variations in the hydrogen chemisorption energy for different active centres have an impact on the overall reaction kinetics.
