Adaptive soft-matter machines are developed using the complex multiphase organohydrogels with multistable mechanical states.
Abstract Energy-dissipation elastomers relying on their viscoelastic behavior of chain segments in the glass transition region can effectively suppress vibrations and noises various fields, yet operating frequency those is difficult to control precisely its range narrow. Here, we report a synergistic strategy for constructing polymer-fluid-gels that provide controllable ultrahigh energy dissipation over broad range, which by traditional means. This realized tailoring relaxation confined...
Abstract A complex electromagnetic environment is a formidable challenge in national defense areas. Microwave‐absorbing materials are considered as strategy to tackle this challenge. In work, lightweight, flexible, and thermal insulating Carbon/SiO 2 @CNTs (CSC) aerogel successfully prepared coupled with outstanding microwave absorbing performance, through freeze‐drying high‐temperature annealing techniques. The CSC shows strong reflection loss (−55.16 dB) well wide effective bandwidth (8.5...
Programmable materials that can change their inherent shapes or properties are highly desirable due to promising applications. However, among various programmable shape-morphing materials, the single control route allows temporary states recover unchangeable former state, thus lacking sophisticated programmability for shape-encoding behaviors and mechanics. Herein, dual-programmable organohydrogels featuring supramolecular heteronetworks developed. In system, metallo-supramolecular hydrogel...
Magnetic field-induced droplet actuation has attracted substantial research interest in recent years. However, current magnetic-controlled liquids depend primarily on magnetic particles added to a droplet, which serves as the actuator an open surface. These inevitably suffer from splitting with or disengaging magnet, possibly leading sample contamination, severely limits their transport speed and practical applications. Here, we report simple additive-free method fabricate tubular...

We demonstrate the unidirectional propagation of structure-induced edge waves in a thin plate. These waves, termed designer flexural (DFEWs), are observed along free plate featuring periodically corrugated rectangular grooves. DFEWs can be activated unidirectionally using either pair point sources exhibiting phase differences or “chiral” source characterized by clockwise distribution, as evidenced experimental results. The asymmetric behavior former scenario is attributed to destructive...
