Breaking the Surface: Buoyant Metal–Polymer Open–Cell Hybrid Lattice Metamaterials

open access: yesAdvanced Materials, EarlyView.
Open‐cell metal–polymer lattice metamaterials that defy sinking. (a) Injection process of the polyurethane (PU) foam into the titanium (Ti‐6Al‐4V) hollow‐strut lattice creating the open‐cell Ti‐6Al‐4V+PU hybrid lattice, (b) flotation test of a hybrid lattice specimen, and (c) a digital representation and experimental validation of a marine buoy ...

TESCLA: A Fully Soft Electromagnetic Linear Actuator With Continuous Bending Enabled by Liquid‐Metal Solenoids

open access: yesAdvanced Materials, EarlyView.
TESCLA (tubular electromagnetic soft conformal linear actuator) combines liquid‐metal solenoids and compliant magnetic composites to achieve large‐stroke bidirectional actuation with continuous bending. Integrated inductance‐based self‐sensing enables proprioceptive position estimation without external sensors, providing a versatile platform for soft ...

Defect‐Templated Phase Engineering in Atomically Thin Metals

open access: yesAdvanced Materials, EarlyView.
Graphene defects are transformed from passive imperfections into programmable templates for phase‐selective growth of atomically thin silver. Plasma‐generated boundary defects favor Ag(1), whereas sp3‐rich zero‐layer graphene promotes Ag(2). This defect‐directed intercalation links local graphene chemistry to crystalline phase, electronic structure ...

Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

open access: yesAdvanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...

Buckling behavior of closed-ribs orthotropic steel decks in long-span suspension bridges

open access: yesAlexandria Engineering Journal
Recently, routine inspections of existing orthotropic steel decks (OSDs) have revealed numerous instances of local buckling deformations in the U-ribs, which could significantly affect the structural safety of the bridges.

A new approach to the stability problem of plates subjected to arbitrary complex loading

open access: yesVietnam Journal of Mechanics, 1992
The pre-buckling and post-buckling deformation processes are assumed to be less complicated, i.e. processes of average curvature, the influence of complex loading on the stability of plates was analyzed in [1]. In this paper eliminating this restriction,
