Machine Learning Driven Window Blinds Inspired Porous Carbon‐Based Flake for Ultra‐Broadband Electromagnetic Wave Absorption

open access: yesAdvanced Science, EarlyView.
Inspired by the regulation mechanism of window blinds, this study designs an electromagnetic wave‐absorbing metamaterial. By introducing the magneto‐electric coupling concept and integrating it with an artificial intelligence‐based data‐driven collaborative optimization strategy, the material optimizes impedance matching performance and enhances loss ...

Synergistic Effects of Solid Electrolyte Mild Sintering and Lithium Surface Passivation for Enhanced Lithium Metal Cycling in All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
This study proposes a synergistic strategy combining mild sintering of solid electrolyte pellets with lithium metal surface passivation, effectively suppressing dendrite growth, and enhancing interfacial stability. This approach doubles the critical current density of symmetric cells (1.1 to 2.2 mA cm−2) and extends full cells cycle life at 1 mA cm−2 ...

Neural Network‐Based Permittivity Engineering of Magnetic Absorbers for Customizable Microwave Absorption

open access: yesAdvanced Science, EarlyView.
A neural network‐enabled permittivity engineering paradigm is introduced, transcending traditional trial‐and‐error design. By decoupling electromagnetic parameters and screening a high‐throughput feature space, an ultrathin (1.0 mm) magnetic absorber is inversely designed, experimentally achieving a superior and customizable 5.1 GHz bandwidth and ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

open access: yesAdvanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Quasi‐Antipolar Nanoclusters Driven Superior Energy Storage in High‐Entropy Relaxor Ferroelectrics

open access: yesAdvanced Science, EarlyView.
Quasi‐antipolar nanoclusters are engineered in lead‐free NaNbO3‐based high‐entropy relaxors that weaken polar nanoregion coupling and induce distinct ferroelectric transition under high fields to enable desirable polarization response. This breakthrough system achieves ultrahigh recoverable‐energy‐density (≈18.3 J cm−3), efficiency (≈91.5%), and ...
