Extraordinary Indentation Strain Stiffening Produces Superhard Tungsten Nitrides

Probing the structural and electronic properties of zirconium doped boron clusters: Zr distorted B12 ligand framework

The lowest-energy structure ZrB₁₂ shows that the dopant Zr atom breaks the triangle B₃ present in other M@B₁₂ clusters (M = Co, Rh, Ir) to form a quasi-linear B₃ unit in the B₁₂ motif and induce strong Zr–B interactions that enhance the stability of the neutral half-sandwich ZrB₁₂ cluster.

Investigations on structural determination of semi-transition-metal borides

The present calculations show a series of semi-transition-metal borides with the long-assumed I4/mcm symmetry are dynamically unstable and I4/m structure is predicted to be both energetically and dynamically stable by freezing the unstable phonon mode.
