Rotator cuff tear (RCT) is a common musculoskeletal disease that poses challenges for functional regeneration of the tendon-bone interface (TBI). The transition TBI between soft and hard tissues determines its structural physiological environment complexity. Here, we present an injectable biopiezoelectric material PVA/CNF/BTO@PDA (Piezoelectric) hydrogel based on three-dimensional (3D) printing inspired by "muscle-electrical coupling". This Piezoelectric indicated desirable piezoelectric mechanical properties, excellent biodegradability, biosafety. In vitro, electrical stimulation from Flexcell Tissue Train system promoted polarization macrophages to M2 phenotype, directing targeted aggregation zonal-specific differentiation bone mesenchymal stem cells (BMSCs) formation. Also, optimal could alleviate inflammatory factor expression regulate osteotendinogenic BMSCs under H2O2/IL-1β inflammation environment. Furthermore, in vivo application demonstrates regenerative potential, indicating repair with significantly accelerates promotes healing chronic RCT model. Therefore, our findings propose new therapeutic strategy enhance treatment outcomes RCT.

Covalent organic frameworks (COF) based materials have exhibited excellent gas and visible light absorption capability, yet are very difficult to generate strong oxidative species for photocatalytic mineralization of volatile compounds (VOCs). Here, a facile in situ modulation protocol developed could enable the growth MOx (M = Ti, Zn, W, Ce) with oxygen vacancy (Ov) on –NH2-functionalized COF surfaces construct NH2–COF/Ov–MOx Z–scheme heterojunctions stability efficiency (98.3 %) photo-oxidation formaldehyde, acetaldehyde, acetone. The –NH2 functionalization enhanced VOC chemisorption via H-bond interaction. Moreover, constructed fast charge transfer channel (Ov–M–N) at interface not only promoted directional migration photo-excited carrier, activated adsorbed O2 H2O quickly •OH, but also effectively inhibited injurant formation realize precise control conversion path. These findings offer new insights into customizing interfacial structure indoor air purification.

Based on the heterogeneous composite design of C3N4 and TiO2, photocatalysts C3N4@TiO2 (with varied molar ratios to TiO2) were synthesized by a water bath method degrade RhB in wastewater. The composition, morphology, structure, photocatalytic properties materials assessed through variety characterization techniques. results show that TiO2 nanoparticles are uniformly coated two-dimensional g-C3N4 nanosheets, forming relatively dense heterostructures within composite. Due synergistic effect derived from component appropriate proportion light absorption range is extended, separation/transport performance photon-generated carrier improved. As result, TCNT-3 (where ratio 1:1) presents remarkable performance, degradation rate which for 60 min 99.8%, reaction constant calculated be 0.0872 min–1. Moreover, efficiency remains 94.4% after 5 cycles, indicating superior cycle stability.
