3D Acoustic Imaging Hitting the Diffraction Limit via Fully Parameter‐Optimized Meta‐Lens and Frequency‐Domain Reconstruction

Advanced Materials, EarlyView.
This article employs a binary genetic algorithm to design an ultra‐fine ultrasonic meta‐lens, achieving lateral super‐resolution imaging in the far field (>20λ₀). Building on this, longitudinal resolution is effectively restored through frequency domain reconstruction.

Microstructural Evolution Dynamics in Rapid Joule Heating Densification of High‐Nickel Cathodes

Advanced Materials, EarlyView.
Introduction of high‐temperature rapid Joule heating combined with two‐step sintering drives full densification while suppressing grain coarsening in high‐Ni cathodes. By activating lattice and grain boundary diffusion over surface diffusion, this approach achieves dense microstructures without excessive grain growth, offering insights into the ...

Machine Learning‐Enhanced Modular Ionic Skin for Broad‐Spectrum Multimodal Discriminability in Bidirectional Human–Robot Interaction

Advanced Materials, EarlyView.
A machine learning‐enhanced modular ionic skin with broad‐spectrum multimodal sensing is realized through a synergistic material–algorithm optimization strategy. This strategy involves hard‐segment‐modulated 1D/2D/3D‐ionic conductors and a data‐driven decoupling model trained on a curated multi‐stimuli dataset.

Iron‐Catalyzed Laser‐Induced Graphitization Enabling Current Collector‐Free Electrodes With Spatially Tunable Iron/Iron Oxide Phases

Advanced Materials, EarlyView.
Iron‐catalyzed laser‐induced graphitization (IC‐LIG) enables the eco‐efficient fabrication of current collector‐free carbon electrodes on renewable substrates, outperforming traditional methods. Tunable ink rheology supports spray coating, screen printing, and DIW of complex patterns, while laser post‐treatment allows spatial control of iron phases ...
