Herein, we report the discovery of hexagonal close-packed Pt–Ni alloy, despite the fact that Pt–Ni alloys are typically crystallized in face-centred cubic structures. The hexagonal close ...

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 ...

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 ...

Engineers at MIT and the University of Tokyo have produced centimeter-scale structures ... are packed with hundreds of billions of hollow aligned fibers, or nanotubes, made from hexagonal ...

Chemists have discovered that pointy gold tetrahedrons self-assemble into 2D chiral superlattices. The structures could ... The material's hexagonal domains form when the tetrahedrons come ...

For thousands of years, the honeycomb’s hexagonal structure has been noted and ... minimum amount of wasted volume is the so-called close packing, which consists of layers of spheres whose ...
