Abstract Surfactant‐free one‐step redox reactions between two types of metal cations enable the synthesis core‐shell nanoparticles without sophisticated control. The reduced noble form a solid core, and transition dissolved upon oxidation induce subsequent formation oxide shell. Various nanostructures are obtained from combination reduction‐preferring Au 3+ , Pd 2+ Pt Rh Ir cations, oxidation‐p...

Vanadium–oxygen materials are of interest for various applications and fields solid-state physics owing to the unequaled plethora different phases. The wealth phases complexity its phase diagram infer a strong sensitivity on growth parameters each phase. Thus, reproducible vanadium-oxide thin-films defined by nonequilibrium techniques is challenging. Here, it shown that ion-beam sputter-deposit...
