Kresling Origami‐Based Metamaterial Robot for Dynamic Electromagnetic Control

Advanced Science, EarlyView.
A reconfigurable metamaterial system integrates deformable origami units with high‐permittivity ceramic plates. Pneumatic switching between structural states alters local resonance conditions, enabling dynamic radar stealth and adaptive microwave reflection for mobile communication.

Chiral Plasmonic Printing of Discrete Hierarchical Chiral Au@Chiral Ag Semi‐Core‐Shell Nanorods With Chiral Plasmon‐Enhanced Photocatalysis

Advanced Science, EarlyView.
Chiral plasmonic printing uses CPL as a chiral stimulus to guide asymmetric Ag deposition on chiral Au NRs seeds. Under CPL, hot carriers reduce Ag+, and the process is controlled by both the CPL handedness and the chiral SPR. L‐dc Au generates more hot electrons under LCP than RCP, while D‐dc Au shows the opposite, revealing chiral photon‐selective ...

Lightweight, Elastic Ceramic Fabrics for Broadband Electromagnetic Absorption and High Temperature Thermal Insulation

Advanced Science, EarlyView.
This study reports lightweight, elastic ceramic fabrics with broadband electromagnetic absorption (EAB = 9.8 GHz) and high‐temperature thermal insulation, enabled by precise microstructural control during ultrafast high‐temperature sintering (UHS), which induces the precipitation of defect‐rich t‐ZrO2 nanograins and turbostratic C nanoclusters.

Wafer‐Scale Atomically‐Thin Gold: Transferable Platform for Flexible Optoelectronics, Thermal Management and Bio‐Interfaces

Advanced Science, EarlyView.
Combining template stripping with a graphene‐inspired transfer yields continuous, transferable gold films at 6‐inch wafer scale with thicknesses approaching the atomic limit. The atomically smooth, near‐bulk‐quality films offer above 86% transmittance and sub‐20 Ω/square sheet resistance, serving as a universal platform for flexible optoelectronics ...
