In the Feature Article by Achim Walter Hassel et al. (pp. 2380–2392), a novel approach of producing metallic nanostructures is reviewed. Directional solidification of eutectics is a route to produce iso-oriented metallic single crystalline nanowires. Etching or electrochemical oxidation allows selective dissolution of either of the phases to produce nanowire arrays, isolated nanowires, nanopore arrays and also derived structures by combining various process steps. A good understanding of the thermodynamics and the kinetics of the phase transformation and chemical reactions in the systems NiAl–X (X = Re, W, Mo), Ag–Cu and Fe–Au was reached. The image on the back cover shows an array of rhenium single crystalline nanowires embedded in the NiAl matrix after partial dissolution of the matrix. Functional devices based on these nanowires, like high aspect ratio nanowire based STM tips, nanoelectromechanical systems, nanowire pH sensors and sensor arrays were constructed.
