Rapid gelation remains essential in maintaining uniform network structures and mechanical properties under mild conditions. Here, we report a strategy based on a glycosyl radical to achieve rapid gelation within tens of seconds. Mechanistically, glycosyl sulfinates serve as efficient precursors to glycosyl radicals upon treatment with potassium persulfate (KPS) through a single-electron transfer process. The following polymerization process exhibits a gentle increase in exotherms and viscosity, which promotes the homogeneity of the polymer network. Glycosyl units are partially incorporated into polymer chains as hydroxyl-rich termini with the remainder freely dispersed throughout the hydrogel matrix, both forming extensive dynamic hydrogen bonds with polymer backbones. Consequently, the hydrogels exhibit exceptional mechanical performance, including high strength, toughness, elasticity, and fatigue resistance. This robust method is compatible with various vinyl monomers, glycosyl sulfinate derivatives, and even harsh environmental conditions. As a proof-of-concept application, the precursor solution can rapidly form uniform gel films via controlled spraying, highlighting potential applications in flexible electronics, wearable sensors, and biomedical dressings.

Since the traditional approaches for 3,3’-diamino-4,4’-azofurazan (DAAF) synthesis are not environment-friendly and economical enough, the development of green and low-cost approaches for the synthesis of DAAF is valuable and significant. Herein, the electrochemical synthesis of DAAF from the oxidation of 3 4-diaminofurazan (DAF) was studied in different electrode and electrolyte systems. It was found that the pH of alkaline aqueous electrolyte, the solvent of electrolyte and electrode play important role in DAF oxidation into DAAF. In an electrochemical cell with graphite sheet anode, Pt wire cathode and DAF/ n Bu 4 NBF 4 /acetonitrile electrolyte, the optimal DAAF yield of 63% and faradic efficiency above 60% (at 1.80 V vs. Ag/AgCl) were achieved. Mechanism investigations revealed that the electrochemical synthesis of DAAF in such an electrochemical cell is originated from the direct oxidation of DAF on graphite anode, not involving radical pathway.

A composite photocatalyst, xTCN (xOTiO2/g-C3N4, where x represents the added quantity of graphite carbon nitride (g-C3N4)), was synthesized using a straightforward one-step hydrothermal method with H2O2 as an oxidant. The H2O2 incorporation into the xTCN composite facilitated the enrichment of oxygen (O) in titanium dioxide (TiO2). This synthesis process effectively reduced the bandgap energy, minimizing the recombination of photogenerated carriers. Concurrently, an O atom was integrated into the g-C3N4 molecule, which altered its bandgap structure and enhanced the photogenerated electron-hole separation efficiency. The dual modification effect was observed when 0.9TCN was used as the catalyst, which converted 77% of benzalcohol with a selectivity exceeding 99%. Additionally, five cycles of reuse only slightly decreased the benzalcohol conversion (by 16%) and selectivity (by 9%), indicating good reusability of the xTCN photocatalyst. The xTCN photocatalyst had an unchanged molecular structure before and after the photocatalytic reaction, demonstrating its superior light stability. The potential photocatalytic reaction mechanism was explored through an active species capture experiment and a Mott-Schottky (M-S) curve test. The results of these studies suggested that •O2- and •OH were the primary reactive species in the photocatalytic reaction.

Piezocatalysis promises sustainable water purification but remains constrained by ephemeral and nonselective radical pathways in complex aqueous environments. Herein, this study reports a defect-engineered BiFeO 3 piezocatalytic peroxymonosulfate activation system, which manifests efficient catalytic dynamics through dual nonradical oxidation pathways involving high-valent Fe(IV) = O species and piezo-induced holes. Experimental and theoretical analyses unveil a closed-loop Fe(II)/Fe(III)/Fe(IV) = O redox cycle sustained by the synergy of oxygen vacancy defects and piezoelectric polarization, enabling persistent nonradical oxidation. This system achieves over 99% bacterial inactivation within 30 min and unprecedented pollutant degradation rates (e.g., k = 0.174 min −1 for Sulfamethoxazole, 0.477 min −1 for Rhodamine B), outperforming state-of-the-art radical-based BiFeO 3 systems by 2−40 fold. The catalyst retains robust activity across broad pH ranges, anion-rich environments, and real water matrices. This work not only advances the mechanistic understanding of piezocatalysis beyond conventional radical pathways but also establishes a design framework for durable, efficient, and self-sustaining piezocatalytic systems for scalable water purification.

Singlet oxygen ( 1 O 2 ) is an efficient reactive oxygen species that, due to its relatively long lifetime and broad pH adaptability, has been considered an excellent alternative to free radicals in advanced oxidation processes. However, achieving sustained 1 O 2 generation and its effective degradation of target pollutants remains challenging. In the present study, a facile co-precipitation–calcination–microwave approach was employed, incorporating Biscogniauxia mediterranea metabolites to promote the formation of zero-valent cobalt. Consequently, a highly dispersed cobalt nanocluster catalyst (Co@NC-800-MW) was successfully prepared, which markedly enhanced the catalyst’s electron-transfer efficiency. Density functional theory calculations of adsorption energies indicated that 1 O 2 generation was thermodynamically favored. Electron paramagnetic resonance (EPR) measurements demonstrated that Co@NC-800-MW maintained continuous 1 O 2 production and played a central role in the degradation of ciprofloxacin (CIP), exhibiting high catalytic efficiency over a wide pH range (3.0–9.0). Furthermore, continuous-flow experiments confirmed the catalyst’s stability: after treating 500 mL of actual water sample with 10 mg of Co@NC-800-MW, the CIP removal rate remained at 80 %. In addition, ecotoxicity tests revealed that the treated water exhibited significantly reduced biological toxicity. These findings provide important theoretical support for the application of advanced oxidation technologies in practical water pollution remediation.

2-Nonenal, a primary component of the characteristic “aging odor,” poses minimal toxicity but significantly affects quality of life and psychological well-being, necessitating its effective removal. However, the existing removal methods mainly rely on adsorption of activated carbon or odor masking after diffusion, which suffers from low efficiency and environmental concerns. This study presents an approach for eliminating 2-nonenal through a multilayered composite textile system that integrates the synergistic effects of amine-based adsorption and triboelectric-driven mechanisms, transforming waste static electricity into valuable resources. Manganese oxide particles were loaded onto the surface of PET by hydrothermal method (250.5 g/m2), and then modified by amination, and then combined with other different common fabrics to form double-layer composite fabric. Under 2 Hz friction frequency, interfacial contact electrification generates substantial surface charges up to 40 nC/cycle, with electrostatic effects enhancing catalytic performance through three synergistic mechanisms: (1) Continuous tribo-induced charge injection drives valence state oscillations in manganese oxides, concurrently generating dual reactive oxygen species (•O2– and •OH); (2) Locally intensified electric fields from accumulated interfacial charges significantly reduce activation energy for aldehyde group oxidation; (3) Amino-manganese oxide charge transfer complexes accelerate regeneration of high-valent manganese through electron-bridging effects, achieving 9% improvement in catalytic cycle efficiency. This electrocatalytic coupling mechanism achieves sustained 87.77% removal efficiency for 2-nonenal, providing an innovative self-powered and energy-efficient strategy for aldehyde pollutant remediation.

The construction of built-in electric field (BIEF) in heterojunction is an effective strategy to enhance solar-driven hydrogen (H 2 ) production by minimizing charge carrier recombination and improving transport kinetics. Herein, p-type ternary sulfide CuGaS 2 (CGS) and n-type g-C 3 N 4 nanosheets (CN) are integrated to construct a p-n heterojunction through a simple co-precipitation method for photocatalytic hydrogen evolution reaction (HER). In situ X-ray photoelectron spectroscopy (in situ XPS), in situ electron paramagnetic resonance (EPR) and density functional theory (DFT) calculations revealed that differences in Fermi levels and carrier concentrations between CGS and CN induce charge migration following an S-scheme mechanism, which aligned well with the intrinsic p-n junction field. The escalated BIEF effect enhances interfacial band bending, drives efficient charge separation, and promotes directional charge transfer. As a result, the optimized 20CN/CGS photocatalyst achieves a high H 2 evolution rate of 563 ± 5 μmol g cat −1 , approximately 3.3 times that of CGS. Additionally, the 20CN/CGS exhibits photothermal properties with further boosted HER rate of 732 ± 6 μmol g cat −1 at 35 °C, achieving a photothermal conversion efficiency (PCE) of 11 ± 2 %. This indicates its potential for exploitation of thermal heat from solar spectrum. This work provides a promising strategy for designing high-performance p-n heterojunction governed by S-scheme charge transfer to boost solar energy conversion.

This work reports the development of an advanced multifunctional hydrogel system designed to address the challenges of infectious wound healing and tissue regeneration. We constructed a polyvinyl alcohol–borax/GelMA hybrid hydrogel matrix, endowing the photocurable hydrogel with excellent mechanical properties and self-healing capability. Bacterial cellulose (BC), a naturally derived biopolymer synthesized by specific microbial strains, was incorporated into the hydrogel matrix to enhance its mechanical properties, structural stability, and biocompatibility, while also serving as a scaffold for cellular adhesion and proliferation. Additionally, the hydrogel was functionalized with tannic acid (TA)-modified MXene nanosheets, which imparted superior antibacterial efficacy and enabled photothermal therapy under near-infrared (NIR) light irradiation. In vitro evaluations confirmed the hydrogel's excellent biocompatibility and antibacterial performance, while in vivo studies demonstrated its ability to significantly accelerate the healing of infectious wounds. This was achieved by effectively reducing bacterial load, promoting tissue regeneration, and alleviating local inflammation under NIR irradiation. These findings highlight the potential of this BC-based hydrogel system as a robust platform for combating bacterial infections, facilitating wound healing, and supporting tissue regeneration in the context of complex skin injuries.

Pure bacterial cellulose dressings exhibit limited therapeutic outcomes in skin wound management due to inadequate fluid absorption capacity, poor antimicrobial efficacy, and lack of bioactive components. To address these challenges, this study developed an innovative microporous multifunctional composite foam dressing (pOBC/CP/HA) via a novel in situ gas formation strategy applied to oxidized bacterial cellulose (OBC). This methodology generated microporous OBC (pOBC) by inducing bubble formation through a chemical reaction. TEMPO-mediated carboxylation and structurally regulated pOBC matrix facilitated the homogeneous incorporation of cationic chitosan particles (CP) and anionic hyaluronic acid (HA), yielding a composite material with synergistically enhanced performance. Comprehensive characterization studies revealed that the pOBC microporous structures played a pivotal role in determining the functionality of pOBC/CP/HA. Compared with OBC-based foams, pOBC/CP/HA showed significantly enhanced mechanical strength, fluid absorption, antimicrobial activity, and biofunctionality. The microporous composite dressing effectively promoted hemostasis, inflammation modulation, angiogenesis, and wound closure in a rat model. In vivo results demonstrated that treated wounds achieved an 82.9 % closure ratio by day 7 and attained complete re-epithelialization within 14 days. This study demonstrates the capability to enhance composite performance by manipulating the microstructure of OBCs and systematically elucidates the role of structural parameter differences in regulating biological responses.

The efficient photocatalytic eliminate of persistent pollutants is crucial for advancing photocatalytic technology in environment applications. Constructing efficient heterojunction photocatalysts represents a key strategy for prolonging the lifetime of photo generated charge carriers and enhancing photocatalytic performance. In this study, an In 2 S 3 /TiO 2 -2:1 defect-heterojunction photocatalyst was developed, which exhibited exceptional degradation ability for recalcitrant contaminants including trenbolone acetate (TBA), acetaminophen, and phenol. Remarkably, over 99 % of TBA was degraded in 30 min, with comprehensive environmental risk assessment confirming minimal ecological impact from degradation intermediates. Transient fluorescence spectroscopy and transient surface photovoltage spectroscopy were performed to evaluate the relaxation process of photogenerated carriers. The results showed that the carrier relaxation time of In 2 S 3 /TiO 2 -2:1 defect-heterojunction photocatalyst was significantly prolonged, which effectively promoted the photocatalytic activity. This study provides valuable references for the design and development of high-performance defect-heterojunction photocatalysts.

Paramylon (EP) is a type of β-glucan found in Euglena gracilis, which is characterized by a crystalline structure and insolubility, thereby limiting its practical applications. This study aimed to enhance its utility by preparing water-soluble oxidized EP (OEP) using a 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-mediated oxidation process. When compared with EP, OEP was found to boost glucose intake in insulin-resistant cells while increasing insulin receptor substrate 1 (IRS1) and glucose transporter 4 (GLUT4) levels. OEP effectively reduced fasting blood glucose levels in diabetic mice from 13.41 to 8.86 mmol L–1. OEP protected the liver from damage by enhancing hepatic glucose absorption through modulation of the IRS1/GLUT4 signaling pathway. OEP adjusted hepatic lipid composition, reducing the accumulation of diglycerides and triglycerides, ultimately ameliorating diabetes. Therefore, the OEP demonstrates significant potential as a nutritional substance for regulating blood glucose levels.

The persistence of pharmaceuticals and personal care products (PPCPs) in aquatic ecosystems poses severe environmental risks, primarily owing to their incomplete removal by conventional treatment methods and potential for inducing bacterial resistance. While CdS/g-C 3 N 4 heterojunctions exhibit promise for photocatalytic degradation, the role of nitrogen-defect engineering in steering interfacial charge behavior to synergize photocatalysis with persulfate (PS)-based advanced oxidation remains unexplored. Herein, a nitrogen-deficient Z-scheme CdS/g-C 3 N 4 (CdS/N-CN) heterojunction was designed via hydrothermal synthesis to enable solar-driven cooperative photocatalysis and PS activation for PPCPs degradation. The optimized system achieved complete degradation of 10 mg/L sulfamethoxazole (SMX) within 60 min under visible light, achieving a rate constant (0.157 min −1 ) 29 times higher than pristine g-C 3 N 4 . Mechanistic investigations demonstrated dual-pathway operation: a built-in electric field drove Z-scheme charge transfer, migrating electrons from N-CN to CdS while holes in N-CN served as primary oxidants. Meanwhile, electrons from CdS activated PS to generate sulfate and hydroxyl radicals, with the latter transforming into singlet oxygen for supplementary oxidation. This synergistic photocatalysis-PS activation system maintained efficient redox activity while enhancing charge separation, ultimately enabling effective PPCPs decontamination. This research presents a novel strategy for leveraging solar-driven heterojunctions and persulfate chemistry for sustainable water remediation.
