Scalable Fabrication of Height‐Variable Microstructures with a Revised Wetting Model
Advanced Engineering Materials, EarlyView.Height‐variable microstructures are fabricated using a scalable CO2 laser machining approach, enabling precise control of wettability through structural gradients. Classical wetting models fail to capture height‐induced effects, necessitating a revised theoretical framework.

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices
Advanced Functional Materials, EarlyView.An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

Advanced Functional Materials, EarlyView.Mesenchymal stem cell‐derived nanoghosts (MSC‐NGs) mimic naturally secreted extracellular vesicles (MSC‐EVs) in structure and physicochemical properties but can be synthesized at more translatable yields. As osteogenic agents, MSC‐NGs demonstrate superior outcomes compared to MSC‐EVs.

Vivid Structural Coloration in Transparent MXene‐Cellulose Nanocrystals Composite Films
Advanced Functional Materials, EarlyView.Vivid structural coloration in reflectance and high transparency in transmittance modes are observed in biopolymer‐layered composite films. The ultrathin multilayered structures have unique optical appearance, near‐infrared bandgap, and strong optical reflection caused by alternating MXene and cellulose nanocrystals layers with high refractive index ...
