Dynamic Disulfide Ionogels for Self‐Healing, Transparent, and Elastic E‐Skins

open access: yesAdvanced Materials Technologies, EarlyView.
A dynamic covalent ionogel is designed via polymer–ionic liquid interaction control. The interplay between ionic liquid compatibility, viscosity, and concentration governs polymer segmental dynamics, which in turn regulates disulfide exchange kinetics and mechanical durability.

Analysis of the strength and deformation characteristics of brick-concrete construction waste used as subgrade fill

open access: yesCase Studies in Construction Materials
The utilization of construction waste as railway subgrade fill is of great significance for alleviating the shortage of natural aggregates and improving the resource valorization of solid wastes. Brick-concrete construction waste fill is characterized by

Linking Polyelectrolyte Modification and Enzyme‐Catalyzed Phenolic Acid Functionalization of Cellulose Fiber for Functional Foams

open access: yesAdvanced Materials Technologies, EarlyView.
Cellulose fibers functionalized using cationic poly(Dimethyldiallylammonium chloride) (polyDADMAC) and laccase‐mediated ferulic acid system are processed into foams using different surfactants (Anionic, cationic, and non‐ionic). Fiber–surfactant interactions influence foam stabilization and porous structure formation during convective drying, producing

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

open access: yesAdvanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

open access: yesAdvanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

RESILIENT MODULUS OF SOFT SOIL BENEATH HIGH-SPEED RAIL LINES

open access: yes, 1999
Modern high-speed rail lines are being built increasingly on marginal land, to reach city centers while avoiding housing areas. Often this land is composed of soft alluvial soils, which exhibit a low resilient modulus.
