High‐Performance Bio‐Based Epoxy Vitrimers and Composites: Synergizing Robustness and Reprocessability via Fractional Free Volume Regulation

Advanced Science, EarlyView.
In this work, two bio‐based epoxy monomers were designed to tune the dynamic network of a rigid–flexible hybrid epoxy through free‐volume control, achieving a synergy among high free volume, high cross‐linking density, and segmental mobility while balancing strength and toughness.

Beyond‐Classical Ferroelectric Metamaterials: 3D‐Printed Planar Lattices With Programmable Electro–Thermo–Mechanical Coupling

Advanced Science, EarlyView.
Planar ferroelectric lattices with rationally‐tailored topology and polarization achieve programmable piezoelectric and pyroelectric properties. Analytical modeling, homogenization, and experiments collectively demonstrate enhanced and tunable longitudinal, transverse, and shear piezoelectric responses, together with substantially improved ...

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Effect on compressive and flexural strength of agave fiber reinforced adobes

Journal of Natural Fibers, 2018
Adobe bricks, formed from raw clay, are used as construction materials since ancient times. Their main drawback is a low flexural and compressive strength. Agave bagasse is a waste material from the Mezcal production process.

Multiscale Interfacial Engineering Enables Robust Reconstituted Wood

Advanced Science, EarlyView.
Conventional adhesives used in wood composites create heterogeneous interfaces that cause stress concentration under humid or aqueous conditions, thereby compromising long‐term stability. A synergistic strategy integrating interfacial reconstruction and water‐induced regeneration transforms heterogeneous interfaces into homogeneous ones with ...

Behavior of Ferrocement Reinforced Concrete Beams Incorporating Waste Glass Exposed to Fire

Eng
This study is an experiment that looks at what happens when 18 supported reinforced concrete beams with waste glass inside them are put on fire. All the supported beams were tested under a three-point load. We classified the beams into three groups based

Co‐Design Insights for Mechanically Active Flexible Printed Circuit Boards Through the CurveQuad Origami Robot

Advanced Science, EarlyView.
This paper presents the process of integrating electronics directly into the body sheet of CurveQuad, a small origami robot that can self‐fold, crawl, and steer with a single actuator. The authors design a flexible printed circuit board for the body sheet: the key challenge is to navigate how embedding electronics affects the mechanical properties and ...
