The size of reinforcements is a pivotal and conventional parameter in metal matrix composites . Based on the distinctive preparation process of MXene , this research introduces a novel strategy to tailor the size of Ti 3 C 2 T x through the controlled ball milling of its precursor, Ti 3 AlC 2 . This approach fabricated Ti 3 C 2 T x sheets with sizes of 4.7 µm, 1.8 µm, and 0.6 µm. Subsequently, these Ti 3 C 2 T x sheets are incorporated into a magnesium (Mg) matrix composite to investigate the effect of Ti 3 C 2 T x size on the strengthening performance. The findings reveal a trend wherein the compressive yield strength (CYS) of the Ti 3 C 2 T x /ZK61 composites increases and the failure strain decreases with the decreased size of Ti 3 C 2 T x . Incorporating 4.7 µm Ti 3 C 2 T x results in an 11.0% reduction in CYS coupled with a 50% increase in failure strain. Incorporating 1.8 µm Ti 3 C 2 T x leads to a 4.6% increase in CYS with a 6.5% increase in failure strain. Incorporating 0.6 µm Ti 3 C 2 T x leads to a 10.7% increase in CYS with a 3.2% increase in failure strain.

The nature of vanadium oxides with multiple valence states and a rich species of oxides facilitates the construction of high performance batteries. Among these, vanadium dioxide (VO 2 ), despite offering several advantages, is seldom reported in anode materials due to its inferior cycling stability and rate performance caused by large volume changes. Herein, we employed a rational structural strategy to assemble VO 2 -NTs/Ti 3 C 2 anode with a multidimensional cross-linked structure using VO 2 nanotubes (VO 2 -NTs) and Ti 3 C 2 T x MXene . Specifically, the abundant multidimensional channels of VO 2 -NTs/Ti 3 C 2 reduce the diffusion impedance of the ions, and the enhanced intrinsic conductivity and highly robust structure solve the problems originally present in VO 2 , which are verified in characterization and density functional theory calculations. Consequently, the composite electrode shows ultra-high reversible capacity (1425 mAh g −1 at 1 A g −1 ), excellent cycling performance (516 mAh g −1 at 5 A g −1 after 2000 cycles) and superior rate performance (703 mAh g −1 at 10 A g −1 ), and also exhibits decent sodium storage performance, representing the best comprehensive battery performance of VO 2 -based anodes to date.

Dielectric polymer composites with conducting fillers would have great potential for diverse applications if their severe leakage loss could be addressed. In this regard, ternary composites using both ceramic and conducting materials as fillers might be an enabler for high dielectric constant and low dielectric loss. Herein, ternary composites with both Ti 3 C 2 T x MXene conducting nanosheets and CaCu 3 Ti 4 O 12 (CCTO) dielectric particles embedded in silicone rubber were studied. It was found that a ternary composite with 1.2 wt% (0.40 vol%) Ti 3 C 2 T x MXene and 12 wt% (2.58 vol%) CCTO could provide an overall superior performance that include a high dielectric constant of 8.8, low dielectric loss of less than 0.0015, good thermal stability up to 450 °C, and excellent mechanical properties with tensile strength of 569 kPa, elastic module of 523 kPa and elongation at break of 333%. The outstanding performance is attributed to the improved uniform dispersion and good interfacial compatibility of mixed fillers in the polymer matrix , suggesting ternary composites might be a better option over their binary counterparts in preparing high performance dielectric composites.

Wearable thermoelectric devices hold significant promise in the realm of self-powered wearable electronics, offering applications in energy harvesting, movement tracking, and health monitoring. Nevertheless, developing thermoelectric devices with exceptional flexibility, enduring thermoelectric stability, multifunctional sensing, and comfortable wear remains a challenge. In this work, a stretchable MXene-based thermoelectric fabric is designed to accurately discern temperature and strain stimuli. This is achieved by constructing an adhesive polydopamine (PDA) layer on the nylon fabric surface, which facilitates the subsequent MXene attachment through hydrogen bonding. This fusion results in MXene-based thermoelectric fabric that excels in both temperature sensing and strain sensing. The resultant MXene-based thermoelectric fabric exhibits outstanding temperature detection capability and cyclic stability, while also delivering excellent sensitivity, rapid responsiveness (60 ms), and remarkable durability in strain sensing (3200 cycles). Moreover, when affixed to a mask, this MXene-based thermoelectric fabric utilizes the temperature difference between the body and the environment to harness body heat, converting it into electrical energy and accurately discerning the body's respiratory rate. In addition, the MXene-based thermoelectric fabric can monitor the state of the body's joint through its own deformation. Furthermore, it possesses the capability to convert solar energy into heat. These findings indicate that MXene-based thermoelectric fabric holds great promise for applications in power generation, motion tracking, and health monitoring.

Soft electro-ionic actuators have received extensive research and attention due to their advantages such as low voltage response and adjustable deformation. However, they have not been able to enter the actual industry application like traditional rigid actuators; one of the reasons may be that the kinematic properties of actuators have been less studied. The electro-ionic actuator based on Ti3C2Tx MXene-CNT/PPy electrode prepared in this paper shows good bending displacement (18.8 mm) and strain (0.63%) under 4 V voltage. In this article, the overlapping nature and exponential function relationship of the actuator end-point trajectories are preliminarily discussed, and the morphology change and cubic polynomial function relationship of the actuator body are considered. Moreover, in application, a novel proof-of-concept model of smart wearable finger straps is proposed. This study is a unique attempt and is hoped to provide a new research perspective in the field of soft electro-ionic actuators.

HighlightsWhat are the main findings?3D crumpled MXene with strain wrinkles enhances conductivity and prevents restacking.Cu nanoclusters (3.0 wt%) synergize N-doping for noble metal-like catalytic activity.What is the implication of the main finding?Ultrasensitive dual-analyte non-enzymatic detection of DA/UA with anti-interference capability and rapid response.Novel material design strategies provide new approaches for the development of future high-performance sensors.Simultaneous detection of dopamine (DA) and uric acid (UA) is essential for diagnosing neurological and metabolic diseases but hindered by overlapping electrochemical signals. We present an ultrasensitive electrochemical sensor using copper nanoclusters anchored on nitrogen-doped crumpled Ti3C2TxMXene (Cu-N/Ti3C2Tx). The engineered 3D crumpled architecture prevents MXene restacking, exposes active sites, and enhances ion transport, while Cu nanoclusters boost electrocatalytic activity via accelerated electron transfer. Structural analyses confirm uniform Cu dispersion (3.0 wt%), Ti-N bonding, and strain-induced wrinkles, synergistically improving conductivity. The sensor achieves exceptional sensitivity (1958.3 and 1152.7 μA·mM−1·cm−2for DA/UA), ultralow detection limits (0.058 and 0.099 μM for DA/UA), rapid response (<1.5 s), and interference resistance (e.g., ascorbic acid). Differential pulse voltammetry enables independent linear detection ranges (DA: 2–60 μM; UA: 5–100 μM) in biofluids, with 94.4% stability retention over 7 days. The designed sensor exhibits excellent capabilities for DA and UA detection. This work provides a novel design strategy for developing high-performance electrochemical sensors.

Myocardial infarction (MI) remains one of the leading causes of mortality worldwide, necessitating advanced therapeutic strategies to address the resulting electrical disconnection and pathological remodeling. This study developed a conductive hydrogel by covalently cross-linking silk fibroin and hyaluronic acid, integrating MXene nanosheets to mimic the extracellular matrix (ECM). Results demonstrated that the incorporation of MXene significantly enhanced the hydrogel’s conductivity, with SH-M5 exhibiting the highest conductivity of 0.32 S/m. The SH-M5 hydrogel effectively improved electrical signal transmission and enhanced the recovery of the left ventricular function in myocardial infarction. These findings underscore the transformative role of MXene in enhancing the functional properties of hydrogels for myocardial repair. The conductive hydrogel demonstrated a unique capacity to integrate mechanical reinforcement, electrical conductivity, and biocompatibility, presenting a promising platform for treating myocardial infarction and advancing regenerative medicine.

Superhydrophobic fabrics suffer from being commonly penetrated by moisture after laundering, seriously deteriorating their water repellency after air drying. Numerous researchers have successfully recovered superhydrophobicity by drying in fluid ovens; however, high energy consumption and equipment dependence limit practical applications. Herein, the superhydrophobic photothermal self-healing cotton fabric (SPS cotton fabric) was fabricated by depositing a composite layer of cellulose nanocrystal-MXene (C-MXene) and polyacrylate (PA) coatings on the cotton cloth. Superior photothermal conversion of the SPS cotton fabric performance enables its 10.5–56.8 °C greater temperature than that of the pure hydrophobic cotton fabric under different simulated solar light intensities. After washing, the SPS cotton fabric can spontaneously restore superhydrophobicity with ≈100% efficiency by 30 mW·cm–2 solar light irradiation; in contrast, the single superhydrophobic fabrics recover only ≈71.2%. Even after 10 washing cycles, the recovery efficiency of the SPS cotton fabric only decreases by 0.1%, exhibiting excellent laundering durability. The SPS cotton fabric can retain ultralong time antifrosting (2760 s) and antifreezing (4080 s) capacities due to sustainable water repellency. Remarkably, the excellent self-healing capability of the SPS cotton fabric is attributed to the fact that the coiled nonpolar alkane chains can be restored to a straight state by autothermal drive, confirmed through element analyses and molecular dynamics simulations.

Although MXene and MoS 2 individually possess outstanding anti-friction and wear-resistant properties in numerous applications, the combination of both in the recent past has created a new frontier in cutting-edge applications. The current work insights into the impregnation of porous alumina ceramics in the MXene (1 wt %), MoS 2 (1 wt %), and hybrid (0.5 wt % MXene +0.5 wt % MoS 2 ) solution to fabricate self-lubricating alumina composites via vacuum impregnation method and afterward exploring the mechanical as well as tribological properties of the synthesized composites. A significant strengthening of the matrix for impregnated composites was observed compared to unimpregnated porous ceramics. The impregnated composites were slid against the zirconia ball to assess the friction behavior. The results revealed that the ceramics impregnated with MXene only can reduce COF by ∼43 % of that unimpregnated ceramics; however, in conjunction with MoS 2, the reduction can be lowered to ∼70 % attributed to synergistic effect of MXene and MoS 2 to form the tribo-layer over interacting surfaces. The study concludes that hybrid (MXene/MoS 2 ) impregnation of porous ceramics exhibits excellent self-lubricating properties over other impregnations, making them suitable candidates for advanced tribological applications. This novel combination leverages the unique properties of MXene and MoS 2 to enhance the longevity and performance of porous ceramics in demanding operational environments.

Photodriven CO 2 conversion has been widely recognized as an effective pathway for achieving carbon neutrality. In this paper, we demonstrate the immobilization of bimetallic Zn/Fe ZIF onto the surface of Ti 3 C 2 T x MXene via an in situ growth process for photodriven solvent-free CO 2 cycloaddition. MXene can extend the optical response of bimetallic ZIF into the near-infrared region. In turn, the incorporated MOF particles effectively prevent the layers of MXene from stacking. The resulting Zn 20 Fe 1 -ZIF/MXene has improved activity (96% yield) in the cycloaddition of epichlorohydrin with 1 bar CO 2 under full spectrum illumination (350 mW/cm 2 ) for 6 h, ca. 3.4, 1.7, and 1.2 times higher than those of pure Zn 20 Fe 1 -ZIF, MXene, and the physical mixture, respectively. Besides, this hybrid catalyst provides desirable stability and performance even after several catalytic cycles, exposure to humid environment or under diluted CO 2 (15%). Control experiments and infrared thermography reveal the synergistic photocatalytic-photothermal contribution of hybrid materials to the photoinduced CO 2 fixation. Our research offers a facile method to construct MOF containing photocatalysts for application of CO 2 conversion with high practical utility.

Increasing demand for flexible sensors in healthcare has spurred the development of nanomaterial-polymer composite sensors. However, existing pressure sensors suffer from low sensitivity due to poor interactions between the functional filler and the polymer matrix. For example, the direct chemical bonding of nanomaterials to the surface of chemically inert polymers such as polydimethylsiloxane (PDMS) is not easily achieved. Herein, we demonstrate that MXene can significantly promote the sensitivity of a thin and soft piezoresistive sensor based on a surface functionalized PDMS (FPDMS) sponge. Using plasma treatment, we constructed a MXene-FPDMS (MFP) sponge with high mechanical strength via the interlayer hydrogen bonding effect. The formed MFP sponge structure (∼450 μm in thickness) endows the pressure sensor with a high sensitivity of 14.2 kPa −1 and a low modulus of 9.7 kPa, critical for detecting ultra-low pressures. When operated with deep learning algorithms, the MFP sponge sensor successfully classifies the pronunciation of 26 letters and various polite expressions with an average accuracy of 94 ± 0.6 %. We envision that this work paves the way for the development of intelligent wearable platforms.

The treatment of diabetic wounds remains a serious challenge due to the unfavorable diabetic microenvironment, characterized by high glucose levels, excessive reactive oxygen species (ROS), and chronic inflammation. For decades, several hypoglycemic drugs have been used clinically to decrease blood glucose levels; however, they are unable to regulate in situ hyperglycemic microenvironments. In this study, we introduced a poly (γ-glutamic acid) (γ-PGA)-based microneedle (MN) patch encapsulated with glucose oxidase (GOx)-loaded Ti 3 C 2 MXene nanosheets (MXene) termed MN-PGA-MXene-GOx. GOx, which lowers local glucose and pH by oxidizing glucose, is delivered deep into tissues via the MN patch, while MXene ensures its prolonged release. When the MN patch is exposed to external NIR light, MXene can induce mild hyperthermia, enhance the catalytic activity of GOx, and promote cell proliferation, migration, angiogenesis, and tissue remodeling. Both γ-PGA and MXene possess antioxidant properties, mitigating ROS in the diabetic environment and reducing hydrogen peroxide (H 2 O 2 ) produced during glucose oxidation. In conclusion, this multifunctional microneedle patch provides a novel approach for accelerating diabetic wound healing, utilizing GOx and MXene for in-situ glucose management and mild hyperthermia.
