AbstractVery recently, a novel phase of hydrogenated borophene, namely $$\alpha '$$ α ′ -4H, has been synthesized in a free-standing form. Unlike pure borophenes, this phase shows very good stability in the air environment and possesses semiconducting characteristics. Because of the interesting stiffness and flexibility of borophenes, herein, we systematically studied the mechanical properties of this novel hydrogenated phase. Our results show that the monolayer is stiffer (Y$$_\text {xy}$$ xy = $$\sim $$ ∼ 195 N/m) than group IV and V 2D materials and even than MoS$$_2$$ 2 , while it is softer than graphene. Moreover, similar to other phases of borophene, the inherent anisotropy of the pure monolayer increases with hydrogenation. The monolayer can bear biaxial, armchair, and zigzag strains up to 16, 10, and 14% with ideal strengths of approximately 14, 9, and 12 N/m, respectively. More interestingly, it can remain semiconductor under this range of tension. These outstanding results suggest that the $$\alpha '$$ α ′ -4H is a promising candidate for flexible nanoelectronics.

In the current work, nano boron nitride (BN) reinforced aluminum (Al) matrix composites with different BN amounts (0.5-2wt.%) were produced by the powder metallurgy(PM) route. This fabrication method consists of dispersing, filtering, mixing, drying, compaction, and sintering processes. The density, compressive strength, micro Vickers hardness, microstructure, and phase structures of Al-BN composites and pure Al were examined. The obtained results indicated that minimum porosity (3.2%), highest density (~2.61g/cm3), Vickers hardness (~50HV), and compressive strength (~168MPa) were obtained at 1%BN reinforced aluminum matrix composite. A tremendous enhancement in Vickers hardness and compressive strength of %1BN reinforced Al matrix composite was achieved as ~61% and ~110% compared to pure Al. Consequently, the mechanical strength of BN reinforced Al-based composites enhanced up to 1% nano boron nitride amount. Due to the clumping of BN nanoparticles, the mechanical strength decreased after this content.
