Metal-layer-assisted coalescence of Au nanoparticles and its effect on diameter control in vapor-liquid-solid growth of oxide nanowires
By using the Au-catalyzed vapor-liquid-solid growth of ZnO and In2O3 nanowires as examples,we demonstrate the critical role of the coalescence of Au catalyst nanoparticles in determining the final diameter distribution of ...
Synthesis of hexagonal close-packed gold nanostructures
Solid gold is usually most stable as a face-centred cubic (fcc) structure. To date, no one has synthesized a colloidal form of Au that is exclusively hexagonal close-packed (hcp) and stable under ambient conditions. Here ...
