Marine corrosion poses a critical threat to the safety of offshore oil and gas facilities. To address the intrinsic drawbacks of pristine TiO2, ZnS/CdS/Ti3+-TiO2 nanotube composites were rationally fabricated via a synergistic strategy combining electrochemical anodization and successive ionic layer adsorption and reaction (SILAR) techniques. Structural and optical characterization confirmed that the as-synthesized composites feature a well-constructed cascade band alignment, which efficiently mitigates the recombination of photogenerated electron–hole pairs. Accordingly, the optimized photoanode delivered a high photocurrent density of 279 µA cm−2. When coupled with 316 stainless steel (316 SS), the composite exhibited a pronounced photo-induced potential of −0.89 V (vs. SCE), achieving a remarkable performance enhancement over pristine TiO2. This enhanced photocathodic protection originates from the synergistic interplay between Ti3+ self-doping and the ZnS/CdS heterojunction: Ti3+ self-doping introduces abundant electron donors to enhance the electrical conductivity of the composite, whereas the ZnS/CdS heterojunction broadens the visible-light absorption range and accelerates the separation and directional migration of photogenerated charge carriers.

A sensing film capable of reporting nitrite levels through two optical pathways was fabricated by embedding N-CDs and NED into a PVA matrix. In this sensing film, NED undergoes a Griess-type coupling reaction, resulting in a red color, while the fluorescence of N-CDs decreases as the nitrite concentration increases. These two changes can be used for both quantification and simple visual checks. Under the best conditions, the fluorescence and colorimetric methods had limit of detection of 0.204 μg/mL and 0.178 μg/mL, respectively. A visible color change occurred at about 1.5 μg/mL, allowing for evaluation without instruments. The sensing film was tested on various food samples, such as processed meats, milk products, and vegetable extracts, with results closely matching those from the Griess method. These findings show that this dual-mode platform is practical for quick and sensitive nitrite detection in food analysis.

Functioning as nanoscale “conductors”, 2D transition metal carbides (MXenes) orchestrate interfacial charge-carrier transport between semiconductors. This capability enables precision-engineered control over photocatalytic processes by regulating charge-carrier separation and migration dynamics. However, existing techniques inadequately resolve photogenerated carrier dynamics, hindering rational MXene photocatalyst design. This study addresses this limitation using in situ nanoscale imaging with Kelvin probe force microscopy (KPFM) on a model TiO 2 @MXenes system. We demonstrate that the charge transfer direction is governed by work function ( W F ) difference, allowing for utilizing MXenes as electron- or hole-accepter by tuning the work function of MXenes. Glycerol treatment increases surface ─OH density, lowering MXene W F to 1.31 eV and strengthening hole-extracting electric fields. By doing so, Pt/TiO 2 modified with low- W F MXenes, showing 70.7%–91.7% reduction in charge transfer resistance, displayed the electron-hole transport, which vastly outperforms the electron-electron transport mode. This work offers a quantitative design paradigm linking surface terminations to W F to carrier transport pathways for developing efficient MXene-based heterojunction photocatalysts.

A self-healing and reprocessable polyurethane elastomer was developed via a rigid–dynamic dual network strategy, which integrates a covalent adaptive network (CAN) based on dynamic crosslinkers dimethylglyoxime (DMG) and with the rigid aromatic structure of tetrabromobisphenol A bis(2-hydroxyethyl) ether (TBBPA-BHEE). This work systematically examines the influence of TBBPA-BHEE and DMG on the mechanical characteristics, dynamic reorganization behavior, and self-healing capabilities of the resulting elastomers. Through compositional adjustments, a series of tunable elastomers were synthesized and evaluated. The optimized elastomer demonstrates a tensile strength of 14.8 MPa, a toughness of 58.9 MJ/m 3 , and an elongation at break of 927.9%. These results highlight the efficacy of incorporating CAN structures into polyurethane systems to achieve multifunctional performance. The developed elastomers exhibit excellent reprocessing and recyclability, addressing environmental concerns associated with traditional polyurethanes. Reversible oxime urethane bonds make reshaping and reuse of the new polyurethanes available under mild thermal conditions.

Endometritis, a common gynecological disease caused by ascending bacterial infection, is a leading cause of infertility. Currently, the clinical treatment relies primarily on antibiotic therapy, administered via intravenous injection, oral administration, or local delivery (e.g., intrauterine infusion). Nevertheless, intravenous injection aggravates hepatic and renal burdens, whereas oral administration elicits gastrointestinal reactions; intrauterine infusion suffers from drug leakage from the uterus due to gravity. Therefore, we developed mucoadhesive doxycycline hydrochloride-loaded air microbubbles (Mad-Doxy-MBs) for intrauterine infusion therapy of endometritis to overcome these limitations. The results showed that Mad-Doxy-MBs exhibited an ultrasound contrast-enhancement property so that they could be tracked by clinicians under ultrasound to achieve their precise localization on the endometrium when infused transvaginally. Subsequently, Mad-Doxy-MBs adhered to the endometrial surface and continuously released Doxy, exhibiting robust bactericidal and anti-inflammatory capacities. Compared with daily oral Doxy administration, two once-weekly intrauterine infusions of Mad-Doxy-MBs achieved superior therapeutic efficacy against endometritis while exhibiting markedly lower gastrointestinal toxicity. This drug delivery platform that integrates the properties of ultrasound visualization, mucoadhesion, and sustained drug release offers a clinically translatable strategy for intrauterine infusion therapy of endometritis and opens new avenues for precise and long-term drug delivery in other luminal diseases.

The most severe side effect of chemotherapy is cardiotoxicity, frequently causing myocardial injury characterized by excessive oxidative stress and fibrosis for which effective treatments are lacking. To address this, a hydrogen delivery system, hydrogen nanobubbles (HNBs), was constructed, leveraging hydrogen’s selective antioxidant and antifibrotic properties to counteract doxorubicin (Dox)-induced myocardial injury and explore its mechanism. HNBs were constructed via polymer self-assembly. Nanoparticle tracking analysis indicated a size of 265.1 ± 26 nm. The average hydrogen content of HNBs measured by chemical titration was about 1.9 mg/L. TEM revealed spherical HNBs with a dense outer lipid polymer layer encapsulating hydrogen. CCK-8 assays confirmed over 90% cell viability, demonstrating good biosafety. ROS fluorescence staining and flow cytometry showed that HNBs significantly reduced Dox-induced ROS increases. RT-qPCR revealed the upregulation of antioxidant genes (NRF2, SOD2, and GPX-1). Flow cytometry and JC-1 staining indicated that HNBs mitigated apoptosis and restored mitochondrial membrane potential. TEM displayed reduced mitochondrial damage and intracellular vacuolation. In a Dox-induced cardiomyopathy mouse model, HNBs improved cardiac function, normalized echocardiographic parameters (EF, FS, LVIDs, and LVIDd), and lowered myocardial ROS levels. Ultrasonic enhanced images showed that HNBs have good myocardial differential targeting. In vivo fluorescence imaging of mice showed that HNBs could accumulate in the myocardium in large quantities at 1 h. mRNA-seq and network pharmacology suggested that HNBs inhibit myocardial fibrosis. Masson staining results showed that HNBs could improve Dox-induced myocardial fibrosis. RT-qPCR and Western blotting confirmed the reduced expression of fibrosis markers (ACTA2, COL1, and FN1), preliminarily linking the mechanism to suppression of both PI3K/AKT and TGF-β/SMAD pathways. In summary, HNBs inhibit oxidative stress and myocardial fibrosis, reversing Dox-induced cardiac injury primarily through the dual suppression of the PI3K/AKT and TGF-β/SMAD pathways.

Hydrogel flexible optical fibers (HFOFs) have great potential in environmental monitoring and biomedical applications. However, current HFOFs face significant challenges, including the presence of large amounts of free water and low fiber crosslinking density, which result in poor water retention and environmental tolerance. These issues hinder the stable use of HFOFs as sensing waveguides. This study proposes for the first time a high-water-retention, fine-core HFOF. HFOFs are spun from a polyacrylamide hydrogel material containing glycerol using the drawing spinning method. During the drawing and stretching process, the fiber network porosity decreases, and self-assembly induced by water evaporation generates numerous hydrogen bonds. The hydroxyl groups in the glycerol molecules form hydrogen bonds with water molecules, while a large amount of bound water is generated, thereby enhancing the water retention performance of the HFOFs. HFOF demonstrates excellent water retention (water loss rate: <0.1%/day), stretching performance (500%), light-guiding ability (1.45 dB/cm), and recovery properties (1 min). The highly water-retentive HFOFs are applied in various scenarios, including bionic sensors for vibration detection and flexible sensors for monitoring human respiration and heartbeat. This work offers a new solution for improving the stable use of HFOFs and provides new inspiration for bionic monitoring and wearable human sensors.

Despite extensive exploration of gelatin methacryloyl (GelMA)-based hydrogels for bone tissue engineering, their clinical translation is hindered by a critical trade-off: poor precursor stability leads to rapid sedimentation of bioactive fillers like hydroxyapatite (HAp), while formulations optimized for injectability often sacrifice mechanical integrity or handling precision. To overcome this challenge, we report a rheologically engineered, injectable composite hydrogel scaffold that integrates unmodified gelatin as a thermoresponsive viscosity modulator into a GelMA/HAp matrix. The incorporation of gelatin yields a stable, paste-like precursor at physiological temperature, which effectively prevents HAp sedimentation and enables precise, filamentous extrusion. Subsequent UV crosslinking locks the homogeneous structure in place, resulting in a mechanically robust scaffold with significantly enhanced compressive modulus. In vitro studies demonstrate that this biomimetic microenvironment not only supports high viability and proliferation of bone marrow stromal cells (BMSCs) but also potently enhances their osteogenic differentiation, as evidenced by upregulated alkaline phosphatase activity, Runx2 expression, and matrix mineralization. This simple, one-step strategy successfully reconciles injectability, structural fidelity, and bioactivity, offering a highly promising and clinically translatable platform for minimally invasive bone regeneration.

Bridging biological and artificial systems, intelligent interfaces drive the demand for flexible electronics that emulate the skin’s multifunctionality. However, achieving such multifunctionality in a compact, self-sustained form remains challenging, as multimodal sensors often rely on rigid materials, discrete components, and external power sources. Herein, this study presents a single-component poly(vinyl alcohol) hydrogel e-skin integrating thermogalvanic, piezoionic, and diffusion mechanisms for self-powered sensing of skin temperature, arterial pulsation, and sweat secretion, simultaneously. The hydrogel features high stretchability, low modulus, and a prismatic architecture synergizing ionic polarization. Moreover, a temporal machine learning model with local attention is developed to decouple multimodal signals. Of practical importance, an active multimodal signal generator wristband is developed as a multifunctional human-machine interface for physiological detection, robotic control, and haptic feedback reproduction. Hence, this hydrogel e-skin represents an efficient material platform for intelligent interactions, showing broad potential for real-time health monitoring, robotic control, and virtual reality.

The development of efficient, stable, and low-cost bifunctional oxygen electrocatalysts remains a key challenge hindering the commercialization of rechargeable zinc-air batteries (ZABs). This study presents a facile room-temperature polymerization and solvothermal strategy based on benzoxazine ring-opening polymerization to construct an integrated photothermal electrocatalyst (PTBOZ-60-NC-Fe 3 O 4 ) composed of nitrogen-doped carbon aerogel and Fe 3 O 4 nanoparticles. The catalyst features a hierarchically porous structure with a high specific surface area (up to 1702 m 2 g −1 ) and constructs Fe–N/O dual-active sites through interfacial bonding. Under photothermal assistance, it exhibits enhanced bifunctional activity for the oxygen reduction and evolution reactions (ORR/OER), achieving a low potential gap (ΔE) of 0.636 V, which is among the best reported values and surpasses most state-of-the-art catalysts. When applied in a ZAB, it delivers a high power density of 200.5 mW cm −2 and excellent cycling stability, maintaining stable operation for over 2760 cycles even at −30 °C. This work provides a simple and effective material design strategy for high-performance electrocatalysts suitable for demanding environments, particularly for harsh-environment-adaptable energy storage devices.

Conductive hydrogels demonstrate exceptional potential for applications in biosensors, bionic robotics, and intelligent sensing. However, conventional conductive hydrogels suffer from limitations including inadequate mechanical strength, low toughness, poor anti-drying and freezing resistant. To address these challenges, this work proposes a novel strategy to fabricate a high-strength, anti-drying, and freezing resistant hydrogel based on a deep eutectic solvent (DES) system, using liquid metal as the initiator and the crosslinker. First, Tween-20 was employed as an emulsifier to disperse liquid metal nanoparticles (LMNPs) in a choline chloride-glycerol deep eutectic solvent (DES) through high-speed homogenization. Subsequently, acrylic acid (AA) and acrylamide (AM) were introduced into the above emulsion. Then, a double-network Gel-LM-PVA-P(AA- co -AM) hydrogel crosslinked by liquid metal was formed via ultrasonication inducing LM-initiated radical polymerization. The resulting hydrogel exhibits outstanding mechanical properties and fatigue resistance with a fracture stress of 1.34 MPa, a fracture strain of 517%, a toughness of 5.68 MJ/m 3 , and a Young's modulus of 1.2 MPa. The introduction of DES endows the hydrogel with excellent anti-drying and freezing resistance. Furthermore, the hydrogel demonstrates remarkable antibacterial performance and favorable electrical conductivity (0.30 mS/cm) and remarkable strain-sensing capabilities, enabling rapid, sensitive, and stable responses to diverse human motions. Therefore, this work developed a new method for the preparation of high strength, anti-drying and freezing resistant conductive hydrogel, which demonstrating considerable potential in the field of flexible electronics and wearable devices.

Polyvinyl alcohol (PVA) is a promising biodegradable polymer, but its widespread application is critically constrained by inherent flammability, limited UV resistance, and the mechanical compromises often incurred by conventional flame-retardant modifications. To address these challenges, a novel bio-based phosphorus‑nitrogen synergistic flame retardant (DPP) was developed from pyridoxal phosphate via a facile Schiff base condensation and P H addition route. This well-designed DPP was efficiently incorporated into PVA via a green melt blending process, yielding composites that achieved a simultaneous enhancement of multiple properties. With a 10 wt% DPP loading, the composite exhibited exceptional flame retardancy, achieving a limiting oxygen index (LOI) of 30.5%, a UL-94 V-0 rating, along with a 63.2% reduction in its peak heat release rate (PHRR) and a 32.7% decrease in total heat release (THR). Additionally, it provided outstanding UV shielding performance, with an ultraviolet protection factor (UPF) of 362 and over 99.7% blocking of both UVA and UVB radiation. Impressively, its tensile strength was enhanced to 25.2 MPa, thus overcoming the common performance trade-off. This multifunctionality stems from DPP's well-orchestrated molecular design: it operates through a vapor- and condensed-phase synergistic flame-retardant mechanism and intrinsic UV absorption, while its strong interfacial hydrogen bonding with PVA constructs a physical crosslinking network, underpinning the concurrent mechanical enhancement. This work presents a strategy for fabricating sustainable, high-performance, multifunctional PVA materials. The PVA/DPP composites obtained via this strategy show promising potential for advanced applications such as outdoor protection and safe electronics packaging.
