Advanced Materials, EarlyView.A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Phase Engineering of Nanogold: Non‐Close Packed Square Planes in A′B′ Stacking with a 0.5 Å Channel
Advanced Materials, EarlyView.Gold is well known to adopt the face‐centered‐cubic (fcc) structure. This work presents an unusual non‐close‐packed phase attained in a 40‐atom gold nanocluster, which is in contrast with the close‐packed fcc quasi‐isomer. The non‐compact structure exhibits exclusive square planes in a layer‐by‐layer stacking, hence, possessing a unique 0.5 Å channel ...

Advanced Materials, EarlyView.Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

An Ultra‐Wideband Metasurface Perfect Absorber Based on Hybrid Absorption Modes
Advanced Photonics Research, EarlyView.A Ge2Sb2Te5 metasurface absorber enables polarization‐independent, ultrabroadband (UV–NIR) light absorption with high angular tolerance. Its performance stems from overlapping electric and magnetic dipole resonances in a symmetric structure, achieving 94% average absorption and maintaining 83% even at 70° incidence, promising for integrated ...

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
