Continuous and Large‐Scale: ELEANOR, the Soft Architected Arm Inspired by the Elephant Trunk

Advanced Intelligent Systems, EarlyView.
A large‐scale, architected continuum robot inspired by the macroscopic properties of the African elephant trunk achieves adaptive elephant‐like movements and whole‐body grasping. The results demonstrate that designing from the natural system’s macroscopic properties, rather than prescribing behaviors, provides a powerful strategy for developing ...

Tailoring the Mechanical Properties of Nanocellulose/ABS Composites by Tuning the Grafting Density on Nanocellulose

Journal of Applied Polymer Science, EarlyView.
Tuning the surface grafting density of an amine‐terminated copolymer on cellulose nanofibers controls the fiber–matrix interface in melt‐compounded nanocellulose/ABS composites. Increasing grafting density builds a compliant nanoscale interphase that raises tensile toughness up to ~26‐fold while preserving stiffness and lowering thermal expansion ...

Fundamentals, Advances, and Applications of Electrospun Nanofibrous 3D Materials

Journal of Applied Polymer Science, EarlyView.
Three‐dimensional electrospun nanofibrous systems offer unique properties and microenvironments. These properties are determined by the fabrication strategies employed and can be adjusted by the incorporation of functional additives to achieve multifunctionality for specific applications. The applications range from the biomedical to the environmental,
