Vinyl Acetate‐Enhanced Polyvinyl Chloride Gel with High Electroadhesion and Self‐Heating‐Tunability for Soft Robots in Freezing Environments

Advanced Science, Volume 12, Issue 41, November 6, 2025.
This study presents a vinyl acetate‐enhanced electroactive polyvinyl chloride gel with low‐voltage deformation, strong electro‐adhesion, and controlled heating. Leveraging these synergistic properties, this work develops soft robots capable of fast locomotion, swarm reconfiguration, and low‐temperature operation (‐50°C).

Vibration Analysis of a Pipeline System Based on Model Truncation

Shock and Vibration, Volume 2025, Issue 1, 2025.
Designing a complex pipeline for a floating production storage and offloading (FPSO), particularly over long distances, presents significant challenges in vibration analysis. Traditional modeling methods, which often assume finite lengths and simple configurations, fall short as they do not account for the integrality and locality of long spans and the
