Characterization of Beryllium–Boron-Bearing Materials by Parallel Electron Energy-Loss Spectroscopy (PEELS)

Sc2B1.1C3.2, a New Rare-Earth Boron Carbide with Graphite-like Layers

“…This strongly supports the idea of (B, C) layers. It is worth pointing out the similarity between these results and those obtained for the compounds BeB C which also possess B}C sheets (20).…”

High-Pressure, High-Temperature Syntheses in the B–C–N–O System

“…A unique family of compounds exist that possess the basic structure of -rh B (1, 2, 3), with ''guest'' atoms either substituting for a B in the icosahedra or situated in sites along the [111] diagonal of the rhombohedral unit cell. Examples of B-rich phases with the -rh B structure include B C and B O, the pnictides B As and B P , and the recently described nitrides, B N (4) and B NBe (5). The unusual structures of borides with the -rh B structure impart many unique properties that have important *To whom correspondence is to be addressed.…”

Probing for Structural Features of Boron-rich Solids with EELS

“…Icosahedral structures in different modifications of elemental boron have been investigated, sometimes doped by metal atoms like lithium or vanadium [7,8] or by carbon or oxygen atoms in "B 13 C 2 " or "B 6 O" [9]. Metal borides like BeB 6 and BeB 2 have been described tentatively [10]. TiB 2 appears to be a single example of a boride that has been investigated not only experimentally by EELS and ELNES, but also theoretically by comparing several methods of deriving B K edges on the basis of band structure calculations or multiple scattering theory [11].…”
