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.

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.

In order to overcome the poor mechanical properties and low permeation flux of MXene nanosheets, as well as the easy agglomeration and limited adsorption capacity of attapulgite (ATP), a composite membrane material (Fe-Co/MXene-ATP) was prepared by vacuum filtration method, of which ATP was inserted into the stacking layers of MXene and bimetallic oxides were loaded as active substances. Through a series of characterization and experiments, it was proved that MXene-ATP composite membrane was achieved, and Fe and Co oxides were successfully loaded on it. The membrane material was used to remove methylene blue (MB). Under the optimal experimental conditions, the removal ratio of MB can reach over 90%, the MB flux is 1.94 mL· cm −2 ·min −1 . The removal mechanisms of Fe-Co/MXene-ATP membrane materials for MB were clarified through comparative experiments and free radical capture, and their mechanisms mainly included MXene-ATP bifunctional substrate for synergistic bimetallic catalysis, the MXene confinement effect enhancing catalytic efficiency and stability, and the "adsorption-catalysis-filtration" trinity dynamic removal mechanism. LC-MS was employed to identify the intermediate products generated during MB degradation, and the potential degradation pathways were subsequently deduced.

Sericin bridging builds H-bond networks, delivering 91 MPa strength and 14.3 MJ m −3 toughness. • Discontinuous SiO 2 enables MXene-dominated IR stealth with a 107.8 °C temperature drop. • 34.4 dB EMI shielding is achieved at a thickness of only 63 μm. • PVA/SS matrix and superhydrophobic layer (155.9°) ensure long-term stability. • Gradient architectures enable reliable piezoresistive response for motion sensing. Developing flexible materials with integrated infrared (IR) stealth, electromagnetic interference (EMI) shielding and long-term stability is essential for personal protection and smart wearables. Traditional MXene composites suffer from weak interfacial bonding, poor mechanical properties, easy oxidation, and the functional trade-off between hydrophobic protection and infrared stealth. Herein, a synergistic strategy of multi-level interfacial bridging and discontinuous superhydrophobic barrier was proposed to fabricate MXene/sericin (SS)/PVA flexible films with a micro-nano SiO 2 protective layer. Sericin acts as an interfacial bridge to construct dense and reversible hydrogen-bond networks, effectively improving mechanical performance. The optimized SMSP-35 film with 35 wt% MXene achieves a tensile strength of 91 MPa, a toughness of 14.3 MJ m −3 and 19.2% elongation at break. The discontinuous SiO 2 coating maintains the low-emissivity feature of MXene in the 8–14 μm band, reducing the radiation temperature of a 200 °C target by 107.8 °C. The film (63 μm) realizes an EMI shielding efficiency of 34.4 dB. Combined with the physical barrier of PVA, interfacial bridging effect of SS and superhydrophobic SiO 2 layer (155.9°), the film retains nearly original shielding performance after 5-month ambient exposure with outstanding oxidation resistance. It also exhibits reliable strain response for human motion monitoring. This work addresses the challenges associated with multifunctional incompatibility and limited stability, providing a viable design strategy for flexible multifunctional protective materials.

Prussian blue analogues (PBAs) offer tunable coordination frameworks and intrinsic porosity, yet their limited structural robustness and attenuation capability restrict the performance of PBA-derived electromagnetic wave (EMW) absorbers. These drawbacks can be substantially mitigated in metal-carbon heterostructure systems, yet achieving well-defined multi-component heterogeneous interfaces and controllable magnetic-domain behavior remains challenging. Here, we propose an electrostatic-field self-assisted strategy to construct bimetallic PBA-derived multi-type carbon-encapsulated/MXene (NiCo@C@C/MXene) heterostructures with precisely engineered multi-component interfaces, which create a rich landscape of electrostatically induced dual-coupled interfaces acting as a core mechanism for enhancing dielectric loss. MXene nanosheets and PDA coating reinforce the PBA-derived carbon matrix and form multidimensional conductive pathways, while multi-type carbon matrix, defect porosity, and magnetic nanoparticles collectively enhance interfacial polarization and magnetic loss. The resulting synergy yields optimized impedance matching, strong attenuation, and broadband absorption, enabling the material to achieve a minimum reflection loss (RL) of −58.51 dB and an effective absorption bandwidth (EAB) of 5.44 GHz at an ultrathin thickness of only 1.57 mm. Radar cross-section simulations further reveal domain-coupling networks that intensify EMW dissipation. This work establishes a concise route to address intrinsic PBA limitations and interface-engineering challenges, enabling next-generation high-performance EMW attenuation materials. Using an electrostatic-field self-assisted strategy, bimetallic PBA-derived multi-type carbon-encapsulated/MXene heterostructures were successfully constructed. The electrostatically induced dual-coupled interfaces enabled precise microscopic regulation of interfacial polarization and magnetic domain behavior. At the nanoscale, the synergistic optimization of dielectric loss, magnetic loss, and impedance matching was achieved, offering a concise approach to overcoming the intrinsic limitations of PBAs and providing a theoretical basis for the rational design of next-generation high-performance electromagnetic wave attenuation materials.

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.

Garnet-type solid electrolytes hold great promise for solid-state Li-metal batteries owing to their high ionic conductivity, large shear modulus, and excellent Li metal stability. However, their air instability and poor interfacial contact cause high Li/garnet interfacial resistance and Li dendrite growth. Herein, an ionic/electronic mixed-conductive artificial interlayer (denoted as MLPL), consisting of MXene nanosheets, Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZT) particles, and a poly(ethylene oxide)/lithium salt (PEO/LiTFSI) matrix, is fabricated at the LLZT/Li interface to address these issues. Incorporating MXene and LLZT suppresses PEO crystallization, enhances segmental motion, and efficiently boosts ionic conductivity. The as-obtained MLPL interlayer is thin (15 μm) and exhibits excellent chemical/electrochemical stability and high ionic conductivity (1.48 × 10 −4 S cm −1 at 60°C). Furthermore, it homogenizes interlayer electric field distribution, mitigates electron-induced garnet attack, improves interfacial contact, accelerates Li + transport, and suppresses dendrite growth, as confirmed by field-emission scanning electron microscopy, electrochemical measurements and COMSOL simulations. Consequently, LiFePO 4 /LLZT@MLPL/Li cells exhibit excellent rate performance (95.4 mA h g −1 at 2.0C) and cycling stability (124.2 mA h g −1 after 100 cycles at 0.1C, 135.6 mA h g −1 after 70 cycles at 0.5C, 60°C). This work offers a universal and feasible strategy for interfacial engineering toward high-performance solid-state batteries. Graphical A mixed ionic/electronic conductive MLPL interlayer stabilizes the garnet/Li interface, homogenizes the electric field, and suppresses Li dendrites for high-performance solid-state Li metal batteries.
