The putative global minimum of clusters with formula B10M2 (M = Rh, Ir) corresponds to icosahedral structures formed by two alternately stacked B5 rings with the metals located at the top and bottom vertices. These structures are the closest approximation of molecular clusters to the elusive icosahedral boron. A detailed analysis of the chemical bonding revealed that the covalent character between the transition metal and the boron framework as well as the strong delocalization throughout the structure enhances the stabilization of the icosahedral form.

Parameters of embedded-atom method interatomic potential for boron are presented in this paper. The potential parameters were determined by means of ab initio data for boron cluster B, triangular boro...
We report the observation of the first inverse triple-decker complex in a tri-lanthanide-doped boron cluster. Photoelectron spectroscopy of La3B14- reveals well-resolved photodetachment transitions. Q...
We report ambient electrochemical N2 fixation at low overpotentials by using two-dimensional (2D) β-boron. The metal-free catalyst afforded both an excellent NH3 yield rate and faradaic efficiency, a...
Among coinage-metal nanoclusters with 55-atoms, only Ag55- and Cu55- are the geometric magic-number clusters, as both exhibit icosahedral symmetry. Au55-, however, exhibits much lower symmetry due lar...
To understand the effect of magnesium atom doping on boron clusters, here we report the lowest-lying energy structures and electronic properties of neutral and monoanionic magnesium-boron clusters, in...

A trace element with the atomic symbol B, atomic number 5, and atomic weight 10.81. Boron-10, an isotope of boron, is used as a neutron absorber in BORON NEUTRON CAPTURE THERAPY.
Inorganic or organic compounds that contain boron as an integral part of the molecule.
A technique for the treatment of neoplasms, especially gliomas and melanomas in which boron-10, an isotope, is introduced into the target cells followed by irradiation with thermal neutrons.
A family of icosahedral, lipid-containing, non-enveloped bacteriophages containing one genus (Corticovirus).
A superfamily of parasitic nematodes which requires one or two intermediate arthropod hosts before finally being eaten by the final host. Its organisms occur rarely in man.
