Using PAN as the substrate, a uniform and dense nanofiber membrane was prepared via electrospinning. It features structural stability, lightweight flexibility, and compatibility with sensor integration without compromising racquet performance. • The component design aligns with the principles of functional membrane modification. Doping MXene and PDA@BaTiO₃ into the PAN substrate achieves synergistic enhancement, with 130 mg identified as the optimal doping concentration, providing a basis for membrane performance optimization. • The membrane exhibits outstanding performance: sensors based on the PAN substrate membrane demonstrate a sensitivity of 13.74 V/N and a response time of 1.2 ms. At 10 Hz and 1.5 N, the output voltage reaches 78.42 V, enabling real-time sensing and aligning with the multifunctional application focus in membrane science. • The PAN-based piezoelectric membrane showed no damage or performance degradation after 5000 cycles, meeting long-term usage requirements and highlighting the reliability of functional membrane applications. Accurate capture of table tennis stroke data provides crucial support for personalized training and skill enhancement. However, existing visual monitoring systems struggle to simultaneously detect stroke force and impact location due to interference from ambient lighting and shooting angles, creating a core bottleneck in intelligent table tennis training. To this end, this study innovatively proposes an integrated flexible piezoelectric sensor solution. Utilizing polyacrylonitrile (PAN) as the substrate, a PAN/MXene/PDA@BaTiO₃ piezoelectric composite film was prepared via electrospinning technology. An integrated design was adopted, where an 8-channel piezoelectric sensor array was constructed on the front side of the racket, and a signal acquisition and wireless transmission module were integrated on the back side, enabling real-time and accurate capture and transmission of hitting signals. Experimental results indicate that the composite membrane exhibits optimal piezoelectric performance at a PDA@BaTiO₃ doping concentration of 130 mg, achieving a sensitivity of 13.74 V/N with a response time of only 1.2 ms. It maintains excellent mechanical stability even after 5000 cycles of load testing. The integrated racket demonstrated outstanding dynamic sensing capabilities in both ball-bouncing and rally tests. This research not only provides a novel technical approach for table tennis training but also lays a technological foundation for flexible sensing technology in the field of smart sports.

Monitoring humidity accurately and reliably is critical for healthcare, human–machine interaction, and smart systems. However, existing humidity sensors struggle to simultaneously achieve ultrahigh sensitivity, fast response, environmental stability, and mechanical flexibility. Inspired by the cerebral cortex's folded structure and neural protection mechanisms, we develop a bioinspired flexible humidity sensor based on alkalized MXene (aMXene), oxygen vacancy-engineered TiO 2 (O v -TiO 2 ), and sodium lignosulfonate (SL). The aMXene mimics cortical folds to provide abundant water-adsorption sites, SL acts as a protective “meningeal” layer to enhance hydrophilicity and oxidation resistance, and O v -TiO 2 nanoparticles function as “synaptic” sites to promote water dissociation and ion transport. This neuron-network-inspired synergy enables an outstanding response (26369) over a wide humidity range (11%-98% RH), a fast response time of 1 s, low hysteresis (2.24%), and robust flexibility (stable after 100 bending cycles). The sensor further demonstrates reliable non-contact interaction, real-time respiratory monitoring, and diaper wetness detection. This work offers a general biomimetic strategy to integrate structural and functional design for next-generation intelligent sensing systems.

To address the performance limitations of hydrogels in complex and demanding environments, this study focuses on transforming them from single-function materials into integrated intelligent systems. A multifunctional AUMG6 hydrogel was developed by integrating a urushiol-acrylamide (UH-AAm) copolymer and MXene nanosheets into a water-glycerol binary solvent. The synergistic dual-network structure, which is reinforced by intercalation-enhanced physical interlocking with MXene, exhibited robust mechanical properties, including high elongation (520%), tensile strength (103 kPa), toughness (314 kJ/m3), and compressive strength (1246 kPa). The hydrophobic alkyl chains and adhesive catechol groups enabled strong adhesion to both dry and wet substrates (e.g., wood, glass, silicone) and across diverse chemical environments. The low-volatility water-glycerol medium significantly suppressed dehydration, maintaining stable adhesion for 90 days and a watertight seal for 7 months under ambient laboratory conditions. The embedded MXene conductive network offered robust electromagnetic interference shielding (41 dB) and high-sensitivity detection of human motion and vocal vibrations. Notably, the hydrogel retained flexibility after 60 days of storage at −20 °C, 20 °C, and 60 °C, and retained sensing reliability after 60 days of storage at −20 and 60 °C. This study presents a hydrogel system with durable mechanical, adhesive, electromagnetic, and sensing performance, demonstrating promising potential in applications such as extreme-environment electronics, underwater adhesion, EMI shielding, health monitoring, and intelligent voice recognition.

To improve the durability of terahertz (THz) electromagnetic shielding materials in atomic oxygen environments relevant to low Earth orbit (LEO), two MXene/para-aramid nanofiber (ANF) composite architectures were designed, including a uniformly blended structure and a sandwich configuration. Ti 3 C 2 T x MXene was used as the conductive phase, while ANF served as a protective matrix. Oxygen plasma treatment was employed to simulate atomic oxygen exposure. The results show that the plasma resistance of blended films strongly depends on MXene content. Increasing the MXene fraction enhances conductive network redundancy and reduces conductivity degradation. In contrast, the sandwich-structured film exhibits superior structural stability. The outer ANF layers effectively limit direct plasma–MXene interaction and undergo surface carbonization during plasma exposure, forming an additional diffusion barrier. As a result, the sandwich film maintains stable THz shielding performance, with the average shielding effectiveness increasing from 42.6 dB to 44.9 dB after plasma treatment. These results indicate that structural regulation of the internal conductive network, which limits plasma penetration, is essential for maintaining stable MXene-based THz shielding performance under oxidative plasma conditions.

AgNP/MXene arrays enabled a compact biomimetic SERS e-nose. • Chemically distinct MXenes generated cross-reactive VOC responses. • MXene adsorption and AgNP enhancement produced VOC fingerprints. • Four similar VOCs were classified with 100% accuracy by PCA/HCA. • Three sensing channels achieved efficient VOC discrimination. The discrimination of structurally similar volatile organic compounds (VOCs) remains a significant challenge due to the limited selectivity of existing sensing materials. To address this, we present a methodologically novel, novel bio-inspired electronic nose platform based on a surface-enhanced Raman scattering (SERS) sensor array of silver nanoparticles/MXene (AgNP/MXene) composites for intelligent VOC identification. The proposed approach combines a rationally designed, chemically orthogonal MXene library (Ti 3 C 2 , V 2 C, and a high-entropy MXene, TiVCrMoC 3 ) with an optimized multivariate analysis workflow, thereby establishing a generalizable methodology for constructing cross-reactive SERS sensing systems. The MXene components serve as superior adsorbents to preconcentrate VOC molecules, while the in-situ grown AgNPs provide strong plasmonic enhancement, translating adsorption events into distinct molecular “fingerprint” spectra. The cross-reactive responses of the array to four similar VOCs (dipentene, ethyl lactate, isopropyl acetate, and propylene glycol monomethyl ether). The generated multidimensional SERS data is effectively decoded using pattern recognition algorithms, namely hierarchical cluster analysis (HCA) and principal component analysis (PCA), which provided a reliable proof-of-concept for the identification of VOC gases. This work thus introduces a new materials–data co-design strategy for biomimetic SERS e-nose development, enabling reliable discrimination of structurally similar VOCs in complex environments.

Nuclear energy expansion drives increasing uranium demand, yet acidic in-situ leaching generates toxic, radioactive wastewater that poses severe ecological and health risks. Conventional treatment methods face efficiency, cost, and operational constraints, necessitating high-performance adsorbents. Here, we report a phosphate-functionalized MXene composite hydrogel (P(AM-VPA)/MXene) synthesized via in-situ polymerization for uranium capture. The material demonstrates exceptional mechanical stability, efficient photothermal conversion, a Langmuir-estimated maximum monolayer adsorption capacity of 1376.75 mg·g −1 at pH 6, high selectivity for uranium over competing metal ions, and 89.8% capacity retention after six adsorption-desorption cycles. Under visible light irradiation, adsorption efficiency increases by 18.4% due to accelerated ion diffusion. MXene reinforcement optimizes the hydrogel’s porous architecture while providing abundant active sites, synergizing with phosphate groups to enable chemisorption-dominated uranium binding. This work provides a phosphate-functionalized MXene-hydrogel design that integrates U(VI)-binding phosphate groups, MXene-induced structural reinforcement, recyclability, and photothermal-assisted adsorption, offering a complementary strategy for uranium-bearing wastewater treatment.

Non-nanoscale strategy enables high-performance flexible humidity sensing. • Synergistic CMC-MXene coupling amplifies humidity-induced transport response. • Ultrawide-range (11–97% RH) detection with a high response of 89.5%. • Excellent temperature stability, bending durability, and biodegradability. Flexible humidity sensors for wearable health monitoring and environmental sensing require simultaneously high sensitivity, operational stability, and environmental sustainability. However, most high-performance devices still rely on non-degradable polymers or elaborate nanostructured bio-based architectures. Here, we report a biodegradable resistive humidity sensor based on a vacuum-filtrated carboxymethyl cellulose (CMC)/MXene composite membrane. CMC provides abundant hydrophilic-OH and -COOH for efficient moisture adsorption, while MXene forms a percolated conductive network. Humidity-dependent XRD shifts indicate tunable MXene interlayer spacing within the CMC matrix, which modulates intersheet contacts and thus the effective conductive pathways, leading to an amplifies electrical response. The optimized sensor exhibits stable and highly reproducible responses over 11–97% relative humidity (RH), achieving a maximum humidity response value (-ΔI/I₀) of 89.5% at 97% RH, with a response/recovery time of 131/340 s. The device maintains performance underrepeated bending (100 cycles), long-term operation (10 days), and temperature variation. Importantly, the membrane shows rapid disintegration in soil within 30 days, offering a promising route toward high-performance yet sustainable flexible humidity sensing without nanocellulose fibrillation or complex device architectures.

The self-stacking of the MXene material can diminish its interlayer spacing and active surface area, thereby diminishing the sensitivity and response speed of pressure sensors. Here, we introduce a high-performance flexible tactile sensor utilizing a composite of MXene, polystyrene (PS) microspheres, and bacterial cellulose (BC). PS microspheres are integrated within the MXene nanosheet layers to mitigate the self-stacking. By employing an innovative point-to-point conductive network design, the self-aggregation issue of MXene materials is effectively mitigated, leading to the formation of dynamic point-contact structures among PS microspheres. This configuration notably enhances detection sensitivity within the low-pressure range to 568.8 kPa–1 (20–200 Pa). Furthermore, the incorporation of BC enhances the interfacial bonding strength through hydrogen bonding, thereby enhancing sensor stability. The sensor exhibits a rapid response time of 29 ms, a wide detection range of up to 0–50 kPa, a low limit of detection of 2 Pa, and consistent signal stability over 20,000 cycles. It has demonstrated the capability to monitor a broad spectrum of physiological activities, including joint movements, facial microexpressions, and radial pulse. Integration with wireless transmission technology enables remote health monitoring, flexible touch keyboard functionality, and human–computer interaction. Additionally, the electromyography (EMG) skin sensor based on the MXene/PS/BC (MPB) composite film accurately distinguishes muscle movements, gestures, acoustic vibrations, and facial microexpressions by detecting surface EMG signals. This comprehensive approach offers a comprehensive solution for wearable medical devices that combine high sensitivity with practicality.

Sepsis-associated intestinal injury represents a critical pathological event contributing to multiple organ dysfunction, with its pathogenesis closely linked to excessive oxidative stress and hyperactivated endoplasmic reticulum stress. Current clinical interventions lack the capacity for precise modulation of the intestinal microenvironment, while existing nanozyme systems generally face challenges such as low oral delivery efficiency, insufficient stability, and uncertain biosafety. To address these limitations, we developed a novel oral nanozyme delivery system based on 2D V 2 C MXene. Through surface modification with hydroxyethyl cellulose (HEC), we constructed a V 2 C@HEC (CV) nanozyme with enhanced physiological stability and intestinal mucoadhesion. In both in vitro and in vivo studies, the CV nanozyme demonstrated significant reactive oxygen species (ROS)-scavenging capacity. Oral administration of CV effectively mitigated intestinal barrier damage and improved survival in a septic mouse model. Mechanistic investigations suggested that the protective effects of CV may be associated with ROS clearance and modulation of endoplasmic reticulum stress, with inhibition of the ATF6/CHOP signaling pathway potentially serving as one underlying mechanism for its cytoprotective function. In summary, this study not only presents a novel nanozyme material with favorable biocompatibility, excellent stability, and a defined antioxidant mechanism, but also provides an innovative materials-based strategy for the treatment of sepsis.

To address the sluggish dehydrogenation kinetics and high operating temperatures of LiBH 4 , Ti 2 VC 2 MXene was incorporated with LiBH 4 to modify its dehydrogenation performance. With 40 wt% Ti 2 VC 2 MXene additive, the onset dehydrogenation temperature of LiBH 4 is reduced to 98.31 °C, while the peak hydrogen release occurs at 332.86 °C. Isothermal dehydrogenation measurements demonstrate that the composite rapidly desorbs 9.50 wt% H 2 within 40 min at 325 °C, 10.67 times faster than that of LiBH 4 . Furthermore, the addition of 40 wt% Ti 2 VC 2 MXene effectively lowers the activation energies for the dehydrogenation to 104.76 and 112.99 kJ mol⁻ 1 , respectively. Mechanism studies reveal that the enhanced dehydrogenation performance originates from the in-situ formation of catalytic active species, including Ti 0 , V 0 and Li 3 BO 3 , promoting the cleavage of ionic and covalent bonds in LiBH 4 . Simultaneously, the multiphase Ti/V/Li 3 BO 3 hetero-ensembles create abundant interfacial boundaries, serving as efficient pathways for hydrogen diffusion and accelerating the dehydrogenation kinetics.

Transitioning toward sustainable energy systems requires H 2 production routes that are both efficient and environmentally responsible. In this work, biomass-based photocatalytic H 2 production was systematically investigated by integrating catalyst synthesis optimization with environmental assessment. A CdS-based photocatalyst modified with Ti 3 C 2 T x MXene was synthesized via an ultrasound-assisted approach, and the effects of ultrasonication conditions, catalyst loading, and reaction temperature on photocatalytic performance were evaluated. Under optimized conditions, the MXene/CdS photocatalyst achieved a H 2 production rate of 16.212 mmol g −1 ·h −1 with good cycling stability. To assess the environmental implications of different experimental strategies and operating conditions, a cradle-to-gate life cycle assessment was conducted and complemented by outdoor photocatalytic tests under natural sunlight. The results indicate that moderate ultrasonication, appropriate catalyst dosage, and optimized reaction temperature can effectively reduce environmental burdens. Variations in solar availability further influence environmental performance, highlighting the combined importance of process optimization and realistic operating conditions. Overall, this study demonstrates that coupling photocatalytic performance optimization with environmental assessment provides a more comprehensive understanding of the opportunities and limitations of biomass-based H 2 production.
