A Zn/Cu MOF–i‐MBene hybrid electrode (ZC‐MYB) for supercapacitors is developed. The composite retained 81% of its specific capacitance after 9000 cycles, increasing it by 46% over ZC MOF and 5.6‐fold over i‐MBene. At 2 mV/s, the asymmetric ZC‐MYB/AC device produced 73.4 F/g.

Boriding of steel surface with beams of boron atoms
We consider a new method for hardening the steel surface, which differs from the known CHT boriding method in the possibility of creating a surface with a lower fragility.

A number of superconductors are found among binary and ternary boride compounds. The highest {Tc}'s are often fund near a limiting composition for the compound's stability. Ternary borides have been a fertile area for exploring the interaction between superconductivity and magnetism, and appear to be the area in which further aspects of boride ...

A conductive ZrB2 ceramic composite strategy was developed for Mg3(Sb, Bi)2 thermoelectrics to regulate carrier transport and phonon scattering through heterointerface engineering. The 1.0 wt.% ZrB2 composite achieved enhanced room‐temperature performance, with a power factor of 28.51 µW cm−1 K−2 and a peak ZT of 1.22 at 573 K.

Boriding kinetics and mechanical properties of borided commercial-purity nickel [PDF]
362-368Kinetics of boride layer growth and tensile behaviour in borided commercial-purity nickel was investigated. Boriding was carried out in a solid medium consisting of Ekabor-II powders at 1173, 1223 and 1273 K for periods of 3, 5 and 8 h.

Ni:Cu (3:1) films, sputtered on nickel foam form self‐supported electrocatalysts for alkaline water splitting. The hydrogen evolution electrode (270 nm) overpotential at −50 mA cm−2 drops from 215 to 136 mV after 72 h, owning to Cu leaching . For oxygen evolution, it reaches 370 mV at 10 mA cm−2.
