Abstract: Abstract Hardness was measured for six different nominally pure and single-phase high-entropy diboride ceramics with the AlB2 structure that were produced by a two-step process. Most of the ceramics had relative densities greater than 99.5%.… read more here.

Abstract: AlB2-type metal diborides represented by MgB2 become an important type of conventional superconductors. However, AlB2-type HfB2 is not superconductive. Pressure-induced HfH10 are predicted to be high-temperature superconductors. Here, first-principles swarm-intelligence structural search calculations identified two… read more here.
