Moth‐Wing‐Inspired Multifunctional Metamaterials
Advanced Materials, EarlyView.This study develops a moth‐wing‐inspired heterogeneous metamaterial that achieves synergistic broadband sound absorption, mechanical energy dissipation, and thermal insulation within a lightweight architected framework. Combining bioinspired gradient design, genetic‐algorithm optimization, and additive manufacturing, the bionic heterogeneous acoustic ...

Advanced 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 ...

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
Advanced Materials, EarlyView.A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Optimal Bandwidth Selection for Conditional Efficiency Measures: a Data-driven Approach [PDF]
In productivity analysis an important issue is to detect how external (environmental) factors, exogenous to the production process and not under the control of the producer, might influence the production process and the resulting efficiency of the firms.

Stable P‐Type PbS Quantum Dot Ink for all‐Blade‐Coated Short‐Wavelength Infrared Photodiodes
Advanced Materials, EarlyView.Stabilization of p‐type PbS quantum dot ink is achieved through hydrogen bonding between fluorinated alcohols solvent and the MP ligand, allowing a six‐day shelf‐life. The solvent does not compromise pre‐deposited layers, enabling fully blade‐coated photodiodes in both n–p and p–n architectures, with enhanced detectivity and bandwidth compared to layer‐
