The AL shows high similarity all sampled 15 species exhibits ≈4–7 times transpiration speed higher than leaves. More importantly, can achieve several photosynthesis without energy provided respiratory action ones. This demonstrates feasibility creating ALs leaf‐like gel structures opening up new avenues conversion, environmental engineering, biomimetic applications.

This paper introduces a novel hybrid honeycomb (HC) design achieved by continuously blending non-auxetic hexagonal and auxetic re-entrant cell geometries along the out-of-plane direction. These HCs are additively manufactured via fused deposition modelling (FDM) using PA12 polymer reinforced with 15 wt.% of discontinuous carbon fibres. We study mechanical piezoresistive performance under quasi-static in-plane loading performed at temperatures ranging between 25-125°C. The results demonstrate significant compression enhancements in configuration, achieving up to 43% increase collapse strength 119% absorbed energy. incorporation multiple layers structure further enhanced properties, ultimately 181% enhancement energy absorption. honeycombs also showed pronounced response gauge factors range 18–37 within elastic regime, making them suitable for wide multifunctional applications.

Abstract Mimicking the characteristics and achieving specific functions of biological systems is stirring but challenging. Generally, pigments in commercial coating can only achieve a similarity chromaticity, while cannot obtain solar reflective spectrum whose difficulty resides simulating spectral simultaneously.
