A Termite‐Inspired Alternative to Cement

open access: yesAdvanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Ultrafast Adhesion/Friction Bidirectionally Switchable Control by Vibration

open access: yesAdvanced Functional Materials, EarlyView.
Bioinspired gradient smooth architectures enable vibration‐switchable adhesion/friction with 62.02 kPa adhesion strength, 131.57 kPa shear strength, tilt angles ≥ 3°, roughness ≥ Ra 0.8 µm, 400 Hz antivibration robustness, and dual‐mode control. The synergy of geometry optimization and vibration modulation tuning bridges multidomain adaptability and ...

Charge‐Induced Morphing Gels for Bioinspired Actuation

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Flora

open access: yes, 2011
L’articolo riesamina la storia del foulard Flora, parendo dal suo disegno originale realizzato nel 1966 dall’illustratore e scenografo italiano Vittorio Accornero (1896-1982), disegnatore tessile per Gucci tra gli anni Sessanta e il 1981. Il disegno Flora è una composizione di fiori, bacche e insetti raffigurati con la precisione di un naturalista in ...
