Zn-Fe Flower-like nanoparticles growth by gas condensation

• Hybrid sputtering/gas agglomeration system produces flower-like Zn-Fe NPs. Fast, simple and reliable method to produce bimetallic nanoparticles. Molecular dynamics shows the growth mechanisms of particles. Galvanic couple between Zn –Fe protects Fe from oxidation. Bimetallic nanoparticles have gained attention in last decade due their unusual characteristics compared monometallic counterparts. However, production such particles with controlled morphologies composition needs be explored understood. In this work, we demonstrate a fast process obtain (Zinc-Iron) (NPs) using hybrid based on combination conventional magnetron sputtering cluster beam source. The morphology structure were characterized by Scanning transmission electron microscopy (STEM), while chemical was evaluated simultaneous acquisition Energy-dispersive X-ray spectroscopy (EDS) Electron energy loss (EELS). Besides, molecular dynamic simulations used model nanoparticle collisions during production, revealing formation
