Cell-instructive polymer hydrogels are instrumental in tissue engineering for regenerative therapies. Implementing defined and selective responsiveness to external stimuli is a persisting challenge that critically restricts their functionality. Addressing this challenge, this study introduces a versatile, modular hydrogel system composed of four-arm poly(ethylene glycol)(starPEG)-peptide and glycosaminoglycan(GAG)-maleimide conjugates.

Lignin is a naturally derived biomacromolecule with excellent biocompatibility and the potential for biomedical application. For the first time, this study isolated nanosized lignin microspheres (LMSs) directly from wheat straw with a polyol-based deep eutectic solvent. The size of these LMSs can be regulated by changing the isolation parameters, ranging from 90 nm to 330 nm.

Degradable and cost-effective cellulose fiber-based materials are ideal substitutes for traditional plastics. However, organic additives used to enhance water and oil resistance often contain toxic substances that may migrate into food, posing health risks. In this study, inspired by tree structures, lignin-containing cellulose nanofibers (LCNFs) are used to form a "crown-roots" structure to enhance the water, oil, and gas resistance, as well as mechanical performance of composites.

Flexible electrochromic devices (FECD) have been widely applied in smart displays, wearable devices, and other fields, however, the synchronous improvement of electrochromic performance and flexibility is still a challenge. In this paper, a fabric-based FECD with "side-by-side" structure is designed and constructed through inkjet printing. The polyaniline nanosheets with good dispersion are used as ink and electrochromic material, and the self-developed semi-solid electrolyte based on polyvinyl alcohol serves as gel electrolyte.

The actual ORR catalytic activity of perovskite materials is significantly lower than the theoretical value due to their inherently low specific surface area and significant segregation of inactive oxygen ions on the surface. This study reports a sol-gel synthesis approach that employs glucose as a structural regulator to fabricate LaSrMnO (LSM) perovskites. Compared with the original LSM (12.
