Enhanced mechanical properties of hBN-ZrO₂ composites and their biological activities on Drosophila melanogaster: synthesis and characterization.

ABSTRACT: In this study, six compositions in the system [x(h-BN)-(100 - x)ZrO₂] (10 ≤ x ≤ 90) were synthesized by a bottom up approach, i.e., the solid-state reaction technique. XRD results showed the formation of a novel and main phase of zirconium oxynitrate ZrO(NO₃)₂ and SEM exhibited mixed morphology of layered and stacked h-BN nanosheets with ZrO₂ grains. The composite sample 10 wt% h-BN + 90 wt% ZrO₂ (10B90Z) showed outstanding mechanical properties for different parameters, i.e., density (3.12 g cm^-3), Young's modulus (10.10 GPa), toughness (2.56 MJ m^-3), and maximum mechanical strength (227.33 MPa). The current study further checked the in vivo toxicity of composite 10B90Z a
