Atomic-scale observation of ordered structure induced by surface segregation in annealed Pt@Co core-shell nanoparticles
Kohei Aso, Hirokazu Kobayashi, Shotaro Yoshimaru +3
The ordered structure of binary alloy nanoparticles determines their magnetic and catalytic characteristics. In the alloys after annealing, one of the components preferentially seg…
Peculiar atomic bond nature in platinum monatomic chains
Jiaqi Zhang, Keisuke Ishizuka, Masahiko Tomitori +5
Metal atomic chains have been reported to change their electronic or magnetic properties by slight mechanical stimulus. However, the mechanical response has been veiled because of…
Shape-dependent local strain in gold nanorods: data-driven atomic-resolution electron microscopy analysis
Kohei Aso, Jens Maebe, Xuan Quy Tran +3
The local variation in inter-atomic distances, or local lattice strain often influences significantly material properties of nanoparticles. Strain measurement with ~1% precision is…
