„Nanoschoten“ aus hoch geordneten, gewellten NiO-Hülsen, die in gleichmäßigen Abständen Pt-Nanopartikel einschließen, wurden durch die Oxidation vielsegmentiger Ni-Pt-Nanodrähte bei tiefen Temperaturen erhalten. Die Ni-Pt-Grenzfläche verstärkt effizient die Diffusion von Ni nach außen im Zuge der Oxidation und erzeugt gezielt Leerstellen in Ni, die intrinsisch unkontrolliert entstehen.
