Magnetism of Higher Borides [PDF]
, 2008 Magnetism of borides which contain the $B_{12}$ icosahedra as a structural building block are attracting increasing interest since they exhibit unexpectedly strong magnetic interactions, despite being magnetically dilute f-electron insulators.

Characterizations and boron diffusion modelling on the AISI H13 steel [PDF]
Journal of Mining and Metallurgy. Section B: MetallurgyA kinetic approach accounting for the linearity of boron profiles through the boronized layers on AISI H13 steel was developed. It aims to track the temporal evolution of the thicknesses of the FeB and (FeB + Fe2B) layers by considering new expressions ...

ZrCo3B2 and HfCo3B2 Electrodes Go on Stage for Oxygen Evolution Reaction
Advanced Science, EarlyView.The intermetallic compounds ZrCo3B2 and HfCo3B2 with distinctive chemical bonding features are excellent OER precursors, restructuring into OER‐active electrocatalysts delivering significantly high OER activities compared to the elemental Co, which is obvious from their lower onset potentials and increased obtained current densities.

Advanced Science, EarlyView.This study unveils a microstructural‐compatibility design strategy that integrates reactive melt infiltration with plasma spraying to fabricate carbon fiber‐reinforced ZrC‐SiC composites. The deliberate incorporation of SiC into the ZrC coating releases heat accumulation, suppresses detrimental lamellar ZrO2 formation, and reduces residual stress. This
