ABSTRACT To enhance the effective cohesion between basalt fiber (BF) and asphalt, an optimal preparation process of nano‐SiO 2 bioinspired grafting BF was proposed using a chemical method based on idea mussel‐plaque. The mechanism grafted analyzed through micro‐morphology, functional group changes, elemental composition tests. cohesive characteristics with asphalt were investigated direct tension tests surface energy theory. results showed that after soaking in 3 mol/L HCl solution (BF ), (SiO ‐BF ) has good wettability asphalt. Alkali metal ions ion exchanged H + solution, forming new Si‐OH bonds more SiO . Compared original reinforced maximum tensile force ductility both increased, wetting angle droplets > NaOH BF. Based theory, functions ‐BF, , improved by 2.8%, 7.4%, 11.6%, respectively, compared to

Leaf venation angle: The physical origin and bio-inspired application

AIP Advances, Journal Year: 2025, Volume and Issue: 15(3)

Published: March 1, 2025

Biomimetic design has emerged as a valuable approach to enhance the physical and mechanical performance of materials structures. As commonly observed object in nature, leaves have inspired numerous interesting practical applications. In this work, through experimental measurements on leaves, we revealed that angle between secondary primary veins is ∼50°, feature remarkably widespread nature. Furthermore, based principle energy minimization, elucidated 50° minimizes bending veins, thereby explaining its prevalence We then designed plate structure analogous leaf venation discovered with (mimicking venation) exhibited 60% higher flexural resistance compared 90° angle. This significant enhancement attributed contribution from vein-like components. The findings study hold promising implications for guiding large-area structures enhanced
