Promoting wound repair by external electric field is a proved effective adjuvant but with single effect and needs additional devices. We designed MXene (Ti3C2Tx)-dominated electroactive nanoplatform (named as PM) which could respond to the natural physiological signals in site convert them into microcurrents of multi-intensity. optimized electrical properties charged surface, superior conductivity permittivity. In vitro studies have demonstrated that PM promotes activity functional cells associated repair. vivo results displayed its promotion equivalent applied on both skin oral mucosal wounds accelerating collagen formation, vascularization re-epithelization. It was first time for biomaterials response regulate bio-electric stimulation without power source, making use from itself. This microenvironment-responsive multifunctionality promising curative design maxillofacial soft tissues defects

Nb₂CT_x MXene Anchored with Carbon Quantum Dots for Lithium-Ion Batteries

ACS Applied Nano Materials, Journal Year: 2023, Volume and Issue: 6(24), P. 23620 - 23629

Published: Dec. 8, 2023

Nb2CTx is a candidate MXene material for lithium-ion batteries because of its advantages in ion movement, diffusion barrier, and average intercalation potentials. However, nanosheets tend to self-restack when assembled into electrodes the strong van der Waals force between them. Electrodes with densely packed can limit Li-ions impair their electrochemical performance. Here, carbon quantum dots (CQDs) are anchored on by hydrothermal reaction expand interlayer spacing create abundant Li-ion transport channels. The CQD-Nb2CTx have higher specific surface area (84 m2/g), more active sites, paths, which facilitate transfer Li-ions. electrode exhibits high capacity 334 mAh/g at 50 mA/g good long-term cycling stability 1000 cycles 260 1 A/g.

The Direct Air Synthesis of Hydrogen Peroxide Induced by The Giant Built‐In Electric Field of Trz‐CN

Small Methods, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Graphitic carbon nitride (C3N4) has been identified as an optimal material for hydrogen peroxide (H2O2) photosynthesis, although its utility is hampered by a high photocarrier recombination rate. Herein, novel with giant built-in electric field (BEF), Trz-CN, synthesized through hydrothermal-calcination tandem strategy. The BEF (4.8-fold) induced the large dipole moment facilitated efficient separation and directional migration of photogenerated carriers. Trz-CN exhibited H2O2 production rate 569.9 µmol·g-1·h-1 using O2 feedstock under visible light (λ > 420 nm), marking impressive 11.2-fold enhancement compared to bulk C3N4. Utilizing air instead pure resulted in trivial 1.6% decrease generation while maintaining substantial 560.6 µmol·g-1·h-1. Notably, showcased sterilization 99.9% against Escherichia coli (E. coli) natural seawater. Density functional theory (DFT) calculations revealed that incorporating nitrogen-rich skeleton into C3N4 enhanced oxygen adsorption capacity lowered energy barrier formation. This leads photocatalytic performance ambient conditions. provides new exploratory idea direct synthesis ballast water treatment.
