Self-healing adhesive hydrogels for sustained ozone release: Enhanced antibacterial properties and improved wound healing.

Antibacterial hydrogels have generated significant interest for their potential therapeutic applications. Ozone (O₃) is recognized for its antibacterial, anti-inflammatory, immunomodulatory, and anti-hypoxic properties, along with its minimal residual impact. However, the development of sustained O₃-release antibacterial hydrogels has been challenging due to the low solubility and short lifespan of ozone.

Curving-Stretching Induced Alignment in Hydrogel Actuators for Enhanced Grip Strength and Rapid Response.

Natural tissues, like ligaments and tendons, display not just robust mechanical performance but also complex anisotropic structures extending beyond one-directional arrangements. However, fabricating hydrogel actuators with biomimetic three-dimensional anisotropy remains challenging. Herein, a simple strategy involving curving-stretching induced alignment is proposed to prepare anisotropic Fe-cross-linked poly(acrylic acid)-poly(acrylamide) hydrogel actuators.

Improved Wallis Dodging Algorithm for Large-Scale Super-Resolution Reconstruction Remote Sensing Images.

A sub-block algorithm is usually applied in the super-resolution (SR) reconstruction of images because of limitations in computer memory. However, the sub-block SR images can hardly achieve a seamless image mosaicking because of the uneven distribution of brightness and contrast among these sub-blocks. An effectively improved weighted Wallis dodging algorithm is proposed, aiming at the characteristic that SR reconstructed images are gray images with the same size and overlapping region.
