Piezocatalytic hydrogen peroxide (H 2 O 2 ) production holds promise as a sustainable technology, but its practicability is hindered by inadequate polarization fields, sluggish charge transport, and rapid bulk carrier recombination. Herein, we propose a catalyst-design strategy integrating bulk iodine doping with surface MXene cocatalyst coupling in a typical piezoelectric bismuth titanate (Bi 4 Ti 3 O 12 , BTO). This design generates intensified bulk polarization fields that markedly suppress electron-hole recombination, while MXene functions as an efficient interfacial electron sink, significantly reducing surface kinetic barriers by facilitating electron transfer for the oxygen reduction reaction (ORR). The optimized iodine-doped MXene-coupled BTO (MBTO-I) catalyst demonstrates a piezocatalytic H₂O₂ production rate of 5890 µmol g⁻¹ h⁻¹ under ambient conditions without any sacrificial agents. Theoretical calculations and advanced characterization techniques reveal that iodine doping effectively lowers energy barriers for *OH intermediate formation and stabilizes O–H bonds, while MXene coupling significantly improves interfacial charge transfer and accelerates the ORR kinetics. Furthermore, the produced H 2 O 2 was successfully employed for bacterial sterilization and rapid degradation of pollutants. Subsequent chemical analyses and biological assessments confirm a substantial reduction in the toxicity of sulfamethoxazole (SMX) degradation products, highlighting the catalyst’s considerable potential for environmental remediation applications.

Aerogel materials are becoming increasingly popular. However, their multi-field applications in complex environments still face challenges. Here, a multifunctional MXene/BC/KH560 composite aerogel (MBKA) with excellent comprehensive properties was prepared using chemical cross-linking and directional freeze-drying technologies. This aerogel is characterized by its lightweight nature, favorable mechanical properties, and controllable surface wettability. Outstanding electromagnetic interference (EMI) shielding performance and photothermal capabilities are endowed by the incorporation of MXene. MBKA achieves an EMI shielding effectiveness of 23.47 dB in the X-band (8.2–12.4 GHz). Additionally, it can heat up to 105.1 °C within 180 s under solar radiation. After hydrophobic modification, a high water contact angle (WCA > 150°) is exhibited by MBKA. Furthermore, its modified and optimized version is suitable for oil/water separation, with an oil absorption capacity ranging from 30.4 to 94.7 g g −1 . Owing to its remarkable photothermal conversion capability, ice formation is effectively prevented or removed by MBKA at −15 °C, with an extended ice delay time (64 min) and rapid photothermal de-icing (55 s) being demonstrated. Therefore, this work provides a valuable strategy for designing multifunctional composite aerogels, demonstrating broad prospects for multi-scenario applications in complex environments.

The development of flexible and robust materials combining efficient photothermal/electrothermal conversion with high environmental stability remains a critical challenge for anti-/de-icing under extreme cold conditions. Here, we report a laser-driven phase transformation and structural engineering strategy to fabricate reduced graphene oxide/MXene@carbon fiber (rGO/MX@CF) composite films featuring tailored microporous architectures. Precise modulation of the laser pulse frequency enables near-complete reduction of graphene oxide (92% conversion of C O to C C bonds), while simultaneously inducing sub-micron honeycomb pores and hierarchical wrinkles. Finite element heat transfer (HEAT) simulations, in high agreement with experimental measurements, reveal that these customized micropores maximize multiple internal reflections and light-harvesting efficiency, significantly enhancing the photothermal response. The optimized rGO/MX@CF-L2 composite establishes a synergistic three-dimensional (3D) photothermal-electrothermal network, where MXene serves as a conductive building block to suppress local impedance fluctuations, ensuring exceptional spatial temperature uniformity. Under a low voltage of 2.5 V or 1-sun illumination, the material reaches steady-state temperatures of 148 °C and 120 °C, respectively. Furthermore, a water contact angle of 135.5° confers robust hydrophobicity and self-cleaning capabilities, while the surface rGO layer acts as an effective passivation barrier to enhance the oxidative stability of MXene. Supported by a high-strength carbon fiber skeleton, the composite maintains a high tensile strength of 61.5 MPa and exhibits superior long-term service stability, achieving complete de-icing within 57 s under synergistic photo-electrothermal driving.

Transition metal carbides (M x C y ) have recently emerged as promising candidates for sodium-ion battery (SIB) anodes, among which Mo 2 C stands out due to its metallic conductivity and favorable Na + migration characteristics. Nevertheless, substantial volume expansion and severe particle agglomeration during cycling impair structural integrity and cycling stability, thereby hindering its practical application. To tackle these intrinsic limitations, we synthesized morphology-modulated Mo 2 C/MXene composites by adjusting the mass ratio of Mo source to MXene precursors. One of these composites forms a 3D hierarchical porous framework, in which Mo 2 C nanocrystals are uniformly anchored on conductive Ti 3 C 2 T x MXene sheets, and is named Mo 2 C / MXene-S. MXene acts as an effective electron-transport network and mechanical buffer to alleviate volume fluctuation of Mo 2 C and suppress structural pulverization. Benefiting from the synergistic effect, the Mo 2 C/MXene-S anode exhibits reversible capacities of 406.5/143.6 mA h g −1 at 0.1/2 A g −1 and retains 296.1 mA h g −1 at 1 A g −1 after 1500 cycles. Kinetic analysis shows that Na + storage is dominated by surface-controlled pseudocapacitance. Density Functional Theory (DFT) calculations demonstrate that the composite optimizes Na + adsorption and reduces the diffusion energy barrier. The Na 3 V 2 (PO 4 ) 3 //Mo 2 C/MXene full cell displays stable cycling, offering an effective strategy for developing high-performance SIB anodes.

The nanoheterojunction (NbCuF@MR) enables tumor-specific copper delivery. • Its TME-responsive design minimizes systemic toxicity and off-target effects. • The cascade amplifies oxidative stress to activate robust ICD. • Cuproptosis–immunomodulation–metabolic interference reprograms the TME. • It enhances immune infiltration, converting “cold” tumors into “hot” ones. Cuproptosis, an emerging copper-dependent programmed cell death, offers a promising strategy for cancer therapy. However, its clinical translation is hindered by non-targeted Cu release, causing systemic toxicity and limited efficacy. To overcome this, we developed a folate-targeted nanoheterojunction photosensitizer, NbCuF@MR, for tumor-specific copper delivery. This system responds to the tumor microenvironment to release active components, leading to mitochondrial copper accumulation, aggregation of lipoylated dihydrolipoamide S -acetyltransferase (DLAT), and induction of cuproptosis. Under 808 nm laser irradiation, Nb 2 C generates mild phototherapy effects that combine to enhance cuproptosis while producing ROS and O 2 . Furthermore, this cascade reactions promotes immunogenic cell death (ICD). Together with loaded R848 and MTX, the system reprograms the immunosuppressive tumor microenvironment through metabolic modulation and amplified cuproptosis, activating a robust antitumor immune response. This stimulates M1 macrophage polarization, DC maturation, and cytotoxic T-cell infiltration, effectively inhibiting both local and distant tumor growth and metastasis. In conclusion, this work offers an innovative strategy leveraging metabolic interference and enhanced cuproptosis to activate potent antitumor immunity.

Developing intelligent fire-safe materials with integrated flame retardancy and rapid fire-warning capability remains a major challenge for next-generation thermal safety systems. In this work, a flexible nacre-inspired multifunctional composite film was successfully fabricated by integrating phosphorylated chitosan (PCS), MXene nanosheets, and hydroxyapatite nanowires (HAP NWs) through a vacuum-assisted filtration strategy. Benefiting from the synergistic effects of phosphorus-induced catalytic charring, MXene-derived barrier protection, and HAP NW-reinforced structural stabilization, the composite film exhibited significantly enhanced thermal stability, flame retardancy, and fire-warning performance. Compared with the pristine chitosan film, the peak heat release rate was reduced by 81.7%, while the composite film achieved an ultrafast fire-warning response time of 0.37 s with stable alarm duration under direct flame exposure. Condensed-phase and gas-phase analyses revealed that the synergistic integration of PCS, MXene, and HAP NWs effectively suppressed combustible volatile release and promoted the formation of a stable inorganic-carbonaceous protective layer. This work provides a promising strategy for developing next-generation bio-based intelligent fire-safe materials for applications in energy storage systems, cable fire protection, and thermal safety management.

Bioinspired lamella-pillar topology enables superelasticity and rapid recovery. • TOCNF separates MXene sheets to prevent restacking and maintain conductivity. • Conformal PMSQ encapsulation protects the framework to suppress MXene degradation • This multiscale design ensures humidity-stable sensing and photothermal functions. Integrating rapid elastic recovery with humidity-resilient electrical functionality in cellulose-based aerogels remains challenging because interfacial instability and moisture-triggered degradation can jointly induce structural collapse and signal drift. Herein, lamella–pillar TOCNF/MXene/PMSQ composite aerogels with a conformal PMSQ-stabilized interface were constructed through a multiscale topology–interface engineering strategy. Directional freeze-casting generates an anisotropic lamella–pillar topology that facilitates reversible deformation and efficient stress redistribution, enabling high compressibility and rapid response/recovery behavior (163 ms/61 ms). The conformal encapsulation of a pre-hydrolyzed PMSQ network reinforces interfacial stability, imparts high hydrophobicity (142.45°), and mitigates humidity-induced electrical drift, while the interpenetrated TOCNF–MXene network maintains continuous three-dimensional conductive pathways. As a result, the aerogels exhibit durable cyclic stability (>8000 cycles) and high pressure sensitivity (235.2 kPa −1 ) with humidity-resilient sensing outputs, enabling reliable physiological monitoring and human–machine interaction under humid conditions. This work highlights the coupling of topology-guided mechanics and interfacial stabilization as an effective strategy toward environmentally robust cellulose-based electronics.

The development of robust and environmentally sustainable polymer composites remains a key objective across advanced manufacturing sectors. In this study, poly (lactic acid) (PLA) composites were prepared via a facile melt-blending approach incorporating surface-modified MXene (Ti3C2Tₓ) nanoplatelets. The MXene was functionalized with polydopamine (PDA), introducing abundant active groups that enhanced interfacial interactions with the PLA matrix through hydrogen bonding. Composites were prepared with varying loadings of pristine and PDA-treated MXene (0.5, 1.0, and 1.25 wt.%). Surface modification was verified using FTIR, XPS, SEM and XRD analyses. The resulting PDA@Ti3C2Tₓ/PLA composites exhibited improved dispersion and significantly enhanced impact strength, dynamic mechanical performance, and crystallization behavior. Notably, the PM1 sample (1 wt.% PDA@MXene) achieved a 37.77% increase in impact resistance (3.10 kJ/m2) compared to neat PLA. Cold crystallization temperature (Tcc) decreased from 125.66°C to 114.83°C, while enthalpy of cold crystallization (ΔHcc) increased from 10.44 J/g to 23.15 J/g, indicating effective nucleation. These outcomes highlight the promise of PDA-functionalized MXene as a multifunctional reinforcement for high-performance, sustainable PLA-based composites.

Novel FMAB-MX beads were developed for efficient phosphate removal and recovery. • The Langmuir maximum phosphate adsorption of 155 mg P g⁻¹ was achieved. • Pseudo-second-order kinetics confirmed a chemisorption process. • Phosphate binding via electrostatic attraction and Fe/Mg chemisorption. • FMAB-MX achieved ∼90% phosphate recovery with excellent reusability. The present study explores a novel Fe/Mg-functionalized alginate–MXene composite bead (FMAB-MX) as an efficient adsorbent for phosphate removal and recovery from water. The physicochemical properties and surface chemistry of FMAB-MX were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) analysis, X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), and Fourier transform infrared spectroscopy (FTIR) to elucidate its structural characteristics and adsorption mechanisms. FMAB-MX achieved phosphate removal efficiency of up to 82% in batch tests, demonstrating approximately 64- and 20-fold higher removal efficiency than MXP and MXB, respectively. FMAB-MX exhibited a maximum adsorption capacity of 155.1 mg P g⁻¹ (475.3 mg PO₄ g⁻¹), whereas FMP-MX showed 64.2 mg P g⁻¹ (196.8 mg PO₄ g⁻¹). Isotherm and kinetic modeling showed that phosphate adsorption onto FMAB-MX was best described by the Langmuir isotherm and pseudo-second-order model, respectively, suggesting monolayer adsorption behavior. FMAB-MX also exhibited high resistance to interference from inorganic anions commonly found in natural water. Furthermore, approximately 89% of the adsorbed phosphate was recovered under mild alkaline conditions, demonstrating excellent reusability and stability over five successive cycles. These findings indicate that FMAB-MX beads represent a sustainable and efficient adsorbent for nutrient recovery and advanced water treatment applications while providing a novel contribution to the still-limited literature on alginate-crosslinked MXene composites for phosphate removal and recovery.

Conventional two-dimensional SERS substrates are often limited by low hot-spot density and poor reproducibility. In this work, a novel three-dimensional (3D) SERS substrate was developed by in situ growing fractal gold nanostructures on a Ti 3 C 2 T x MXene network incorporated into a hydrogel. The coexistence of Au and MXene, confirmed by EDS analysis, provides a composite platform that combines the electromagnetic enhancement of Au nanostructures with the potential chemical-enhancement contribution of MXene. An ethanol-induced hydrogel shrinkage strategy was further introduced to simultaneously concentrate analytes and compress the 3D framework, thereby increasing the local density of active sites and enhancing the SERS response. The substrate exhibited a linear detection range of 10 −8 -10 −4 M for crystal violet (CV) and was successfully applied to the quantitative analysis of ginsenoside Rg3 in ginseng. A detection limit of approximately 0.23 µg mL −1 and an estimated sample content of approximately 1.31 µg g −1 were obtained. This work demonstrates a contraction-assisted Au/MXene 3D SERS platform for sensitive molecular detection. Graphical Synergistic enhancement of SERS signals from Raman reporter molecules (ginsenoside Rg3 in ginseng) arises from the electromagnetic enhancement of gold nanoflowers and the synergistic contribution of MXene.

The Pd NPs@MXene/PVA hydrogel strain sensor achieves an ultra-wide strain range from 10% to 1680% with high gauge factor of 18.4. • The sensor demonstrates self-healing with 98.4% efficiency in 25 s, retains 75% of tensile strength and 89% strain capacity. • Hydrogen bonding and Pd NPs enhance mechanical performance, with tensile strength of 60.8 kPa and fracture strain of 1680%. • Sensor array integrated into smart glove enables object grasping and 0–9 gesture recognition, showing potential for human–machine interfaces. Hydrogel strain sensors are promising for electronic skin due to their flexibility and biocompatibility, yet balancing mechanical robustness, sensing performance, and self-healing remains challenging. Here, we develop an optimized Pd nanoparticles (Pd NPs)-decorated MXene/polyvinyl alcohol (PVA) hydrogel strain sensor (Pd NPs@MXene/PVA) with enhanced multifunctionality. Mechanically, the hydrogel achieves a tensile strength of 60.8 kPa and fracture strain of 1680%, outperforming pristine PVA hydrogel (17.3 kPa, 800%) through dynamic borate ester, hydrogen bonding and Pd NP reinforcement. For sensing, it provides repeatable responses over 100%–1500% strain, with cyclic stability validated at 200%–600%. Detectable responses from 10% to 1680% were observed under monotonic loading, and the maximum GF reached 18.4 in the 1200%–1680% regime. The device responds rapidly (600–700 ms) and was evaluated over 5000 stretching–releasing cycles, with the response becoming markedly more repeatable after an initial conditioning stage. Notably, it achieves 98.4% electrical self-healing efficiency within 25 s, retaining 75% tensile strength and 89% strain capability after healing, which is attributed to the dynamic borate ester bonds between PVA chains and tetraborate ions, together with reversible hydrogen-bonding interactions among PVA, MXene, and Pd NPs. Integrated into a smart glove, the sensor array distinguishes object grasps, generates distinguishable resistance patterns for digit gestures 0–9 and achieves high-accuracy MLP-based classification of digits 1–9, validating its practicality for human-machine interfaces. This work advances hydrogel sensor design by integrating Pd NPs for optimized multifunctionality, offering a robust platform for next-generation electronic skin.

Introduction: Alzheimer’s disease (AD) is a chronic progressive neurodegenerative disorder involving ROS and ferroptosis. MXene, a 2D material, functions as both a drug carrier and ROS scavenger. Butylphthalide (NBP), a neuroprotective agent, suffers from poor aqueous solubility and bioavailability. This study synthesized Ti2C@BSA-NBP, a novel MXene nanocomposite, to enhance NBP delivery and therapeutic efficacy for AD.Materials and Methods: Ti2C@BSA-NBP was synthesized via self-assembly and amidation reaction, and characterized by multiple techniques. In vitro, ROS-scavenging capacity, mitochondrial function, and ferroptosis markers were assessed in H2O2-injured cells. In vivo efficacy was evaluated in an AD mouse model via behavioral, histopathological, and biochemical analyses. Results: The nanocomposite exhibited robust ROS-scavenging activity in vitro, significantly attenuating ROS, restoring mitochondrial function, and reversing ferroptosis markers. In vivo, Ti2C@BSA-NBP ameliorated learning/memory deficits, partially repaired neuronal morphology, and suppressed neuroinflammation. Mechanistically, it downregulated ACSL4 and Aβ overexpression while restoring GPX4 inhibition.Discussion: Ti2C@BSA-NBP exerts synergistic neuroprotection through MXene-mediated ROS clearance and NBP-mediated multi-target regulation, counteracting oxidative stress, ferroptosis, and neuroinflammation.Conclusions: Ti2C@BSA-NBP is a promising multifunctional nanoplatform integrating antioxidant activity, enhanced drug delivery, and ferroptosis modulation for AD therapy.
