Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...

The hexagonal close-packed Pt–Ni alloy nano-multipods ... Benefiting from the unique crystal structure and excavated polyhedral morphology, the highly branched Pt–Ni multipods exhibited ...

While the bcc lattice contains one metal particle in the center of the cube, the fcc structure contains one atom in the center of each face of the cube, which is a more common alloy lattice ...

which is a crystal architecture with eight corner points and a center point. But at extremely high pressure the crystalline structures transform into 12-point hexagonal forms, or a close packed ...

The structure can be visualized as a stacking of octahedral layers and oxygen-deficient hexagonal close-packed AO 3-δ (h') layers (A is a large cation such as Ba²⁺ and δ represents the amount ...
