Ultralow‐Frequency Epsilon‐Near‐Zero States in 3D‐Printed High‐Entropy Alloy Metacomposites for Ultra‐Thin Perfect RF Absorption

open access: yesAdvanced Materials, EarlyView.
Rozanov causality limit—a compulsive proportional thickness‐wavelength relationship (nd ∝ λ)—makes it challenging to develop perfect absorption with both thin thickness and low frequency. Herein, a cocktail effect in high‐entropy alloys (HEA) is crucially utilized for lowering plasma frequency to achieve epsilon‐near‐zero states, which finally enables ...

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

open access: yesAdvanced 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 ...

Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

open access: yesAdvanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.

Meissner Effect and Nonreciprocal Charge Transport in Non‐Topological 1T‐CrTe2/FeTe Heterostructures

open access: yesAdvanced Materials, EarlyView.
This work demonstrates interface‐induced superconductivity (Tc ∼12 K) with a robust Meissner effect and pronounced nonreciprocal transport in epitaxial 1T‐CrTe2/FeTe heterostructures, where 1T‐CrTe2 is a 2D ferromagnet, and FeTe is an antiferromagnetic metal.

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement

open access: yesAdvanced Materials, EarlyView.
The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...
