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

open access: yesAdvanced 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.

Additively Manufacturable High‐Strength Aluminum Alloys with Coarsening‐Resistant Microstructures Achieved via Rapid Solidification

open access: yesAdvanced Materials, EarlyView.
Rapid solidification in laser additive manufacturing facilitates the precipitation of metastable phases in aluminum alloys. These metastable phases significantly enhance the strength by forming a high‐volume fraction of precipitates with an order of magnitude reduced sizes and smaller interspacing, effectively impeding dislocation motion. Consequestly,

Anchoring Redox Mediator on COFs for Efficient Solar to Hydrogen Conversion

open access: yesAdvanced Materials, EarlyView.
In this work, Fe ions are first fixed on COFs skeleton to construct a novel 2D Z‐scheme heterojunction (BWO/Fe/TP1C). The cycling of Fe3+/Fe2+ significantly improves the electron transfer rate. In addition, the construction of 2D Z‐scheme heterojunction not only promotes the separation of photogenerated carriers but also ensures its high redox activity.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.
