Nanocrystal Compressive Residual Stresses: A Strategy to Strengthen the Bony Spines of Osteocytic and Anosteocytic Fish

Advanced Science, EarlyView.
Advanced neoteleost fishbones, such as medaka, challenge bone adaptation strategies. While zebrafish bones contain osteocyte‐mediated porosity, medaka bones lack it, raising questions about alternative reinforcement mechanisms. Using advanced imaging, this study reveals higher residual compressive strains in medaka bone, suggesting an adaptation that ...

State of the Art of Low‐Frequency Acoustic Modulation: Intensity Enhancement and Directional Control

Advanced Science, EarlyView.
High intensity low‐frequency sound sources hold significant value in many fields. However, their long wavelength, strong penetrability, and tendency to diffract make direction control and intensity enhancement challenging. Acoustic generators and metamaterial‐based acoustic devices still face issues such as low energy efficiency, poor directional ...

Artificial Cornea Substitute Based on Hydrogel Skeletons with Natural Stromal Hierarchical Structure and Extracellular Matrix for Sutureless Transplantation

Advanced Science, EarlyView.
Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...
