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,

Autonomous Implants

open access: yesAdvanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach

open access: yesAdvanced Materials, EarlyView.
Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...
