Synthesis of gold square-like plates from ultrathin gold square sheets : the evolution of structure phase and shape
It's hip to be square: Gold square-like plates exhibit alternating hexagonal close-packed (hcp, see picture, yellow) and face-centered cubic (fcc, red) structures in the center and defect-free fcc structures at one pair ...
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 ...
Graphene oxide-templated synthesis of ultrathin or tadpole-shaped Au nanowires with alternating hcp and fcc domains
Ultrathin Au nanowires (AuNWs) and tadpole-shaped nanowires are synthesized on graphene oxide (GO) sheet templates. For the first time, 1.6 nm-diameter AuNWs are shown to contain hexagonal close-packed (hcp) crystal domains, ...
