Abstract Boron allotropes have attracted interest due to their diverse structural motifs and unusual properties; however, despite the many phases identified so far, achieving a boron allotrope that simultaneously exhibits high electrical conductivity and plasticity remains challenging. Here we report the synthesis of Imma-B60, an allotrope that exhibits both high electrical conductivity and plastic deformability, via the high-pressure formation of a Na4B60 precursor followed by sodium degassing.

This version is not peer-reviewed. Submitted: 28 November 2025 You are already at the latest version To reveal its influence on quasicrystal structure analysis, multiple diffraction (MD) effects in a basic Co-rich decagonal Al-Co-Ni quasicrystal have been investigated in-house and with synchrotron radiation. Two weak reflections were chosen as the main reflections (P) in the in-house measurements and 40° ψ-scans of one main reflection have been performed with synchrotron radiation.

Copper and boron seldom engage in reaction at ambient pressure. The few reports on copper-doped boron compounds that exist in the literature often lack definitive stoichiometry. Here, we report successful synthesis of Cu2−δB25 single crystals (δ∼0.03, indicating Cu understoichiometry) via a high-pressure melting method using copper and β-rhombohedral boron as precursors.
