The electrocatalytic hydrogen evolution reaction (HER) is widely recognized as a promising pathway for sustainable energy conversion and storage. Recently, plasmonic enhancement has attracted increasing attention as an effective strategy to improve HER performance by harvesting incident light. However, most metal nanoparticles (NPs) with excellent HER catalytic activity, such as Pt, exhibit a negligible localized surface plasmon resonance (LSPR) effect, thereby limiting their overall efficiency. In this study, we constructed a Pt NPs–Ti3C2 MXene hybrid electrocatalyst via an in situ reduction approach, in which Ti3C2 MXene simultaneously acted as the reductant, structural support, and plasmonic mediator. Under 808 nm laser irradiation, Ti3C2 MXene generated a strong LSPR effect, and the resulting hot electrons were efficiently injected into the Pt NPs/Ti3C2 MXene interface, where they actively contributed to the HER process. Consequently, the hybrid catalyst achieved an overpotential as low as 51 mV at 10 mA cm–2 and a favorable Tafel slope of 61.29 mV dec–1 while maintaining excellent stability. Finite element simulations further confirmed that the LSPR-induced local field enhancement concentrated hot electrons at the Pt NPs/Ti3C2 MXene interface, thereby lowering the activation barrier and accelerating the charge transfer. Overall, this work demonstrates a simple yet effective plasmon–catalyst coupling strategy that provides valuable insights for the design of next-generation plasmon-enhanced electrocatalysts for efficient hydrogen production.

Doxorubicin, as an anthracycline antibiotic, is a commonly used and effective chemotherapeutic agent for treating various malignancies. However, it has a narrow therapeutic window. Therefore, real-time monitoring of doxorubicin concentration in chemotherapy patients is essential for enhancing treatment efficacy, minimizing side effects, and ensuring patient safety. In this paper, we proposed a Ti 3 C 2 MXene-sensitized fiber surface plasmon resonance (SPR) doxorubicin sensor. By covalently functionalizing the reflective SPR sensing structure with Ti 3 C 2 MXene, the refractive index sensitivity increased by 60.0 %. Furthermore, by covalently modifying the doxorubicin-specific aptamer, the sensor achieves high sensitivity and high specificity in the detection of doxorubicin. Within the linear range of 10–100 μM, it demonstrates a sensitivity of 0.24 nm/μM and a limit of detection of 2.79 μM. Furthermore, experiments confirmed that the doxorubicin sensor exhibits excellent specificity and can be applied for the detection of doxorubicin in real serum samples. The proposed doxorubicin sensor offers benefits such as high sensitivity, high specificity, fast response, and small size, and has the potential to meet the clinical requirements for monitoring doxorubicin concentration in chemotherapy patients.

This study presents the development of piezoresistive pressure sensors based on Ti 3 C 2 T x MXene-coated polyurethane (PU) sponges fabricated using Digital Light Processing (DLP) 3D printing. Six different porous structures were designed by varying the line width (300 and 500 μm) and height width (100, 300, and 500 μm) to optimize the sensor performance. The 500 × 300 μm structure demonstrated an optimal balance between sensitivity and measurement range, achieving resistance change rates from −11.02 % at 25 Pa to −163.78 % at 2.25 kPa. DLP 3D printing allows precise control of pore geometry with dimensional accuracy within 50 μm, while eliminating the complex multistep fabrication processes associated with traditional template methods. The sensor exhibited excellent durability, with less than 1.5 % performance variation after 1000 compression cycles at both 1 and 2 kPa values. Environmental stability tests revealed minimal interference from humidity (30–90 % RH) and predictable temperature-dependent behavior (20–90 °C). Cytotoxicity assessments using RAW 264.7 macrophages confirmed biocompatibility, with cell viability exceeding 95 % for both MAX/MXene materials and PU/MXene composites. Practical demonstrations, including finger pressing, palm contact, and dynamic tapping, validated the capability of the sensor for human motion detection. The combination of DLP 3D printing precision and MXene conductivity enables the scalable production of customizable pressure sensors for wearable electronics, health monitoring, and human–machine interface applications.

Metal halide perovskite photodetectors (PDs) are attractive for next-generation optical communication and biomedical sensing owing to their high absorption coefficients, bandgap tunability, and solution-processability. However, their practical deployment is hindered by interfacial defects and ion migration, which result in high dark currents, noise, and limited operational stability. Here, we report a dual-interface (DI) engineering strategy that incorporates Ti 3 C 2 T x MXene simultaneously at the buried and top interfaces of the perovskite layer. This approach effectively passivates undercoordinated Pb 2+ /I − sites, suppresses trap-assisted recombination, and mitigates ion migration, thereby enabling ultralow-noise and fast-response devices. The optimized DI PD exhibits a suppressed dark current, a detectivity of 1.94 × 10 12 Jones, a responsivity of 0.44 A W −1 , and rise/fall times of 1.65/1.00 μs at 656 nm. The device retains >97 % of its performance after 60 days of nitrogen storage. Application demonstrations confirm error-free visible-light communication up to 10 kHz and precise photoplethysmography monitoring under varying illumination. This work highlights MXene-based DI engineering as a universal and scalable strategy for advancing high-performance perovskite PDs in data communication and healthcare technologies.

Traditional power technologies are constrained by size and endurance, whereas nanogenerators offer lightweight, environmentally friendly, and sustainable energy solutions. In this study, an MXene/BaTiO3/PAN composite nanofiber membrane was developed using electrospinning technology. The incorporation of BaTiO3 nanoparticles and two-dimensional MXene flakes significantly enhanced the piezoelectric properties of the PAN matrix, resulting in an output voltage of 6.45 V and a current of 308 nA-approximately four times higher than that of pure PAN. Notably, piezoelectric nanogenerators (PENGs) and triboelectric nanogenerators (TENGs) were integrated into one single device, addressing the low output and stability issues of traditional PENGs. The integrated device achieved a higher stable output voltage of 12–14 V and retained stable performance over 5000 cycles. Moreover, the MXene component endowed the nanofiber membrane with excellent photothermal properties, achieving a temperature rise of 42 °C under 1 W cm−2 solar irradiation. This demonstrates its potential for human joint photothermal therapy and underscores its value for developing high-performance self-powered sensors and wearable electronic devices.

The depletion of fossil fuels and growing environmental concerns are accelerating the development of clean hydrogen production technologies. Anion exchange membrane water electrolysis (AEMWE) has emerged as a promising approach owing to its cost-effectiveness and improved stability of nonprecious materials. However, its efficiency is restricted by the sluggish kinetics of the oxygen evolution reaction (OER). Herein, we report a catalyst derived from a high-entropy alloy (HEA), CuFeMnCoNi-NC/MXene, which exhibits remarkable OER activity and durability. The catalyst achieves an overpotential of 267 mV at 10 mA cm–2 and a Tafel slope of 50.9 mV dec–1. It also exhibits low charge-transfer resistance (Rct = 3.4 Ω) and a large double-layer capacitance (Cdl = 27.2 mF cm–2), thereby enhancing the overall electrochemical performance. Notably, the catalyst demonstrates excellent durability, with the overpotential increasing by only 3 mV after 10,000 cyclic voltammetry (CV) cycles. An AEMWE electrolyzer assembled with this catalyst presents 1.91 A cm–2 at 2.0 V and operates at 1.0 A cm–2 for 20 h with a low degradation rate of 0.9 mV h–1.

Polyimide (PI) is well known for its excellent thermal stability and mechanical strength, but its limited thermal conductivity and tribological performance restrict broader applications under harsh conditions. In this work, Ti 3 C 2 T x MXene nanosheets were incorporated into a PI matrix via in-situ polymerization to fabricate high-performance Ti 3 C 2 T x /PI nanocomposites with uniform filler dispersion. The thermal conductivity of the composite reached 1.99 W m −1 K −1 at 20 wt% MXene loading—an increase of 123% over pure PI. The thermal degradation temperature at 10% weight loss (T d10 ) also improved from 577.6 °C to 587.0 °C. Additionally, both storage modulus (E s ) and glass transition temperature (T g ) increased, indicating improved rigidity and thermal resistance. Tribological tests at room temperature and 200 °C revealed that the addition of 5 wt% MXene effectively reduced the coefficient of friction (COF) by 6.52% and 5.37%, respectively. The wear rate was also significantly reduced—by 83.41% at room temperature and 39.66% at 200 °C. These enhancements are attributed to the formation of a continuous and robust transfer film composed of MXene, oxides, and friction-induced organic products. This work provides a promising route for high-performance PI-based composites with improved thermal and tribological functionalities.

Intercalation pseudocapacitance is the key point to achieving the balance between the volumetric capacitance and the rate performance of energy storage. However, the low pseudocapacitive reactivity of the active center still limits the energy density of the pseudocapacitance devices. Herein, we propose a strategy that regulates the p - d hybridization of confined MXene via the co-doping of B and O atoms (BO-MXene) for outstanding electrochemical performance. Both experiments and density functional theory (DFT) reveal that the inner doped O atoms in low 2 p orbital energy strengthen the hybridization of Ti and electron-deficient B in MXene for high retention of B atoms, weaken the Ti-O covalency in MXene. As a result, the weakened p - d hybridization of Ti and O for the outer surface and strengthened p - d hybridization of Ti and B for the inner, promote the adsorption of protons and electron transfer, respectively. Further, the BO-MXene-based hybrid supercapacitors achieve a significant volumetric energy density of 56.86 Wh L -1 at 25.6 kW L -1 . This electronic structure via tuning the p - d hybridization in MXene proposes a new path for designing proton-confined intercalation pseudocapacitance.

The shuttle effect of lithium polysulfides (LiPSs) from sulfur cathode to lithium (Li) anode is one of the main obstacles for lithium-sulfur (Li−S) batteries. The severe corrosion of Li metal anode by the dissolved LiPSs bottlenecks the efficient operation of Li−S batteries, however, the anode part has not been received much attention compared to those extensive efforts related to the cathode designs. Herein, we show that the interface between Ti 3 C 2 T x (T=−OH, −F)-based MXene and reduced graphene oxide (rGO) is able to guide uniform Li nucleation, promoting highly reversible and dendrite-free Li plating/stripping. Such the Li anode demonstrates excellent cycling stability for more than 1000 hours even under ultra-high rate (10 mA cm −2 ) and high areal capacity (3 mAh cm −2 ). More importantly, the well-designed 2D layered structure by coupling the Ti 3 C 2 T x with a graphene scaffold, is highly efficient to block the shuttled polysulfides and inhibit the corrosion of the lithium metal anode. As a result, the Li−S full battery exhibits a stable cycling stability with a high Coulombic efficiency of 99.8 % over 300 cycles. This work suggests the design strategy of Li metal anode especially targeting at the sulfur cathode, and we hope it can provide valuable inspirations for the future design of Li metal anodes for more practical Li−S batteries. Graphical MXene shield : The rGO/Ti 3 C 2 T x interfaces favor Li nucleation and deposition, contributing to dendrite-free Li plating/stripping behaviors inside the scaffold. The membrane also mitigates the side reactions of Li by blocking the shuttled lithium polysulfides, which promotes the efficient cycling of Li−S batteries.

Two-dimensional metal carbides or nitrides (MXenes) demonstrated wide applications in energy storage, water treatment, electromagnetic shielding, gas/biosensing, and photoelectrochemical catalysis due to their higher specific surface area and excellent conductivity. They also have the advantages of flexible and adjustable components and controllable minimum nanolayer thickness. In this study, a cube-like Co3O4 particle-modified self-assembled MXene (Ti3C2) nanocomposite has been prepared successfully by a simple solvothermal method. The Co3O4 particles are well dispersed on the surface and inner layers of the Ti3C2 sheets, which effectively prevent the restacking of Ti3C2 sheets and form an organized composite structure. The physical properties of these nanocomposites were studied by using XRD, SEM, EDX, TEM, and XPS. The performance of the obtained samples was evaluated as new nanocatalysts for degrading methylene blue and Rhodamine B in batch model experiments. The prepared Mxene-Co3O4 nanocomposites can be well regenerated and reused for eight consecutive cycles, indicating potential wide applications in wastewater treatment and composite materials.

With the rapid development of artificial intelligence and ever-increasing demand for electronic devices, constructing high-performance flexible pressure sensors is urgently needed. In this study, a novel flexible pressure sensor with superhigh sensitivity and ultrawide detection range is tactfully designed and prepared based on wrinkle-structured MXene film. Due to the unique wrinkle structure, the prepared pressure sensor exhibits outstanding performance including high sensitivity of nearly 860 kPa−1, wide detection range (0.5 Pa ‒ 30 kPa), short response/recover time (40/53 ms) and high stability (11600 cycles). A multi-scale working mechanism is proposed to explain the sensing process. Interestingly, the prepared sensor can easily detect the smallest movement of a millet (2.4 mg) in real time. Based on these advantages, the prepared pressure sensor is expected to show significant potentials in future physiological detection and precision instrument monitoring systems.

Silicon-based anodes offer high theoretical capacity for lithium-ion batteries but suffer from severe volume expansion during cycling, leading to structural degradation and capacity fade. This study presents a novel Si/SiO x @C@MXene composite to overcome these limitations through the synergistic confinement by the metal-organic-framework (MOF) derived carbon and MXene. The resulted Si/SiO x @C@MXene composite features a unique architecture where MOF-derived carbon-coated Si/SiO x nanospheres are embedded within or anchored onto the conductive MXene sheets, forming a robust three-dimensional sandwich-like structure. Electrochemical test reveal that Si/SiO x @C@MXene delivers a high initial discharge capacity of 1158.0 mAh g −1 at 100 mA g −1 , maintains 953.5 mAh g −1 after 1000 cycles at 1000 mA g −1 (84.9 % capacity retention), and exhibits excellent rate capability (543.9 mAh g −1 at 5000 mA g −1 ). This work highlights the effectiveness approach for developing high-performance, stable silicon-based anodes.
