Fiber-shaped supercapacitors (FSCs) serve as optimal energy storage components in wearable platforms. However, traditional fiber materials suffer from poor interfacial cross-linking, disordered microstructures, insufficient active sites, and low electrical conductivity. To overcome these challenges, this research develops Zn-MoO₃/Ti₃C₂Tₓ hybrid fibers via wet-spinning technology employing glacial acetic acid as a coagulation bath, with MoO₃ quantum dots intercalated into Ti₃C₂Tₓ interlayers and Ti₃C₂Tₓ nanosheets cross-linked by Zn 2+ . The resulting hybrid fibers feature expanded interlayer spacing, a large ion-accessible surface area, abundant porous channels, exceptional electrical conductivity, and excellent mechanical properties, delivering an exceptional volumetric capacitance of 2078.2 F cm −3 at 2 A cm −3 with 75.0 % capacitance retention at 20 A cm −3 . Furthermore, the constructed FSCs achieve a substantial energy density of 55.6 mWh cm −3 at a power density of 400 mW cm −3 , with 94.7 % capacitance retention after 5000 cycles, and successfully power an electronic timer, demonstrating their potential for wearable applications.

Factor XIa (FXIa), a pivotal target in anticoagulant therapy, requires precise activity monitoring to assess coagulation status and bleeding risks. To address the limited sensitivity of conventional chromogenic methods, we developed a novel electrochemiluminescence (ECL) biosensor exploring the synergistic effects of MXene's superior conductivity and Prussian blue analogue's (PBA) large specific surface area. Transient absorption spectrometry was employed to determine the excited-state lifetime and to elucidate the functional role of MXene@PBA. Molecular docking and specificity constant analysis identified Mpr(mercaptopropionic acid)-TEARK-Fc(ferrocene) as an optimal peptide substrate. The MXene@PBA-enhanced biosensor quantifies FXIa-induced ECL signal changes via peptide cleavage, achieving a linear range of 1.0 × 10 −5 mIU/mL to 1 mIU/mL and an LOD of 3.7 × 10 −6 mIU/mL (S/N = 3) in human serum. Furthermore, the ECL biosensor demonstrated efficacy in FXIa inhibitor screening, firstly revealing salvianolic acid A and C as potent inhibitors (>60 % inhibition) and apigenin as a moderate inhibitor (~40 %). Molecular docking confirmed that these inhibitors competitively bind to FXIa's catalytic pocket (His57, Cys58, Ala190, Lys192, Ser195), overlapping with the substrate recognition site. This MXene@PBA-enhanced ECL biosensor establishes a robust strategy for both FXIa activity monitoring and therapeutic agent development.

Herein, a biochar-based composite (Ti 3 C 2 T x @biochar-PDA/PEI) was constructed by decorating Ti 3 C 2 T x and polydopamine on coconut shell biochar via electrostatic self-assembly method. Different characterization techniques were applied to explore the structure, morphology and composition of the sorbents. It was found that the higher porosity and diverse functional groups were conducive for Ti 3 C 2 T x @biochar-PDA/PEI to capture radionuclides, and the water environmental conditions made a great contribution to the adsorption process. The process of removing U(VI)/Cs(I) well complied with the Langmuir isotherm and Pseudo-second-order equations, which indicated that the single layer chemical adsorption occurred on the solid liquid interface. Meanwhile, this produced composite exhibited superior removal performance under complex co-existing ion environment, and the maximum adsorption amounts of U(VI) and Cs(I) reached up to 239.7 and 40.3 mg g −1 . Impressively, this adsorbent still exhibited good adsorption performance after three cycles of regeneration. The spectral analysis and DFT calculation demonstrated that adsorption of U(VI) might be a chemical process, while the adsorption of Cs(I) should be ion exchange or electrostatic attraction. This study demonstrated the potential application of Ti 3 C 2 T x @biochar-PDA/PEI as an effective remediation strategy for radioactive wastewater cleanup. Graphical Abstract

Photocatalytic optical hollow fibers (POHFs) coupled with spiral-shaped Cl − adsorption fibers are used to remove trichloroethylene (TCE) from wastewater. The POHFs are hollow quartz tubes coated with Ti 3 C 2 T x -doped oxygen vacancy (OV)-rich BiOBr (BiOBr-OV). The photocatalyst coating enhanced the excitation light intensity onto the photocatalytic fiber surface. The hetero-junction between Ti 3 C 2 T x and BiOBr-OV reduced the bandgap and broadened spectral absorption range of the composite photocatalyst. The material increased the production of reactive · O 2 - and •OH species, thereby improving the degradation of TCE. Spiral-shaped Cl − adsorption fibers comprised of polyethersulfone loaded with ethylenediaminetetraacetic acid-grafted metal–organic framework (MOF-808-EDTA). Tertiary amine groups (−R 3 N) of MOF-808-EDTA exhibited superior Cl − adsorption capabilities. As the Cl − ion indirectly quenches the free radicals, its removal reduced the inhibitory effect of the photocatalytic products, further enhancing the efficiency of TCE degradation and removing its degraded byproducts. TCE, chemical oxygen demand, and Cl − ion removal rates are 98.75, 69.15, and 99.22 %, respectively. Intimate coupling of photocatalysis and ion adsorption provided an effective solution for efficient removal of TCE, its degradation products, and Cl − ions from wastewater.

Based on the thermal energy storage and solar-thermal conversion of solid-liquid phase change materials (PCMs), they feature exceptional potential for energy-saving thermal insulation and solar energy utilization in buildings. However, the inherent low thermal conductivity, susceptibility to leakage and poor solar absorption of PCMs seriously restrict their practical applications. In this work, composite PCMs were fabricated by encapsulating paraffin with diatomite porous ceramics (DC) featuring hierarchical pore structures prepared by foaming and freeze-drying. Excellent sunlight absorption and solar-thermal conversion were achieved by spraying a Ti 3 C 2 T x coating on the DC-paraffin surface. The as-prepared DC 3 -PA with 55.85 % loading on paraffin possessed a satisfactory thermal storage capacity of 112.1 J/g, maintained excellent stability, and improved the thermal conductivity by 107.25 %. The solar-thermal conversion and storage efficiency of DC 3 /T-PA is as high as 95.24 % under 200 mW/cm 2 light intensity attributed to the large broad-band solar absorption and strong localized surface plasmon resonance (LSPR) effect of the Ti 3 C 2 T x coating. This strategy combining hierarchical porous structured ceramic encapsulation and Ti 3 C 2 T x coating surface modification was employed for obtaining high-performance shape-stable composite PCMs, which was expected to achieve potential applications in building energy efficiency, solar energy utilization, and thermal management.

Microwave transmission-infrared stealth compatible materials are critical for radomes and strategic vehicles, but existing solutions fail to balance performance well. MXene shows promise for dual-band applications, yet its continuous films suffer from high radar reflectivity and low transmittance. Herein, MXene-patterned flexible frequency selective surface (FSS) structures were fabricated via screen printing, with systematic control of the parameters of arrays to tailor electromagnetic properties, enabled by tailoring the equivalent inductor-capacitor circuit of the FSS to achieve impedance matching in the radar band. As gap width of arrays increases from 120 to 360 μm, radar transmittance reaches 78% (over 10⁴ higher than that of continuous MXene films) and the reflectivity is significantly reduced from 90% to 16%, while maintaining approximately 80% infrared reflectivity (8∼14 μm, corresponding to an emissivity of 0.2) is retained. This achieves efficient radar-infrared dual-band compatibility, with radar transmittance differing by only approximately 1.01 dB from that of MXene-free structures. The low-cost method provides a feasible pathway for high-performance regulation of dual-band devices, advancing multispectral functional materials and meeting demands in aerospace, stealth protection, and next-gen communications.

The rapid advancement of highly integrated electronics demands next generation electromagnetic interference (EMI) shielding materials that combine lightweight, ultrathin, flexible, and mechanically robust properties with exceptional shielding effectiveness (SE) to mitigate signal crosstalk and ensure device reliability. In this work, we demonstrate the fabrication of high-performance EMI shields using highly conductive, additive-free aqueous Ti3C2Tx (T = O, OH, Cl, F) MXene dispersions synthesized under both harsh and mild etching conditions. These dispersions were engineered into freestanding thin films and functionalized cotton fabrics via vacuum-assisted filtration, enabling tunable EMI shielding properties through precise control of etchant chemistry, flake size, microstructure, thickness, and MXene loading. The EMI shielding improved with film thickness and the 13 μm thick film demonstrated exceptional EMI shielding of 60 dB. The freestanding heat treated Ti3C2Tx film with minimal thickness of 5 µm achieved a remarkable shielding effectiveness of 71 dB (which is 37% higher than the untreated film) corresponding to 99.99999% EMI attenuation. This film also exhibited an ultrahigh absolute shielding effectiveness (SSET) of 72,300 dB cm2 g−1, surpassing all previously reported MXene-based shields of comparable thickness. The improved stability was attributed to thermal conversion of surface OH groups to O-terminations, reducing interflake spacing and enhancing conductivity. The coated cotton fabric achieved an unprecedented SE of 82 dB due to the excellent wave attenuation associated with its porous structure. Notably, the fabric retained its shielding performance even after six months of ambient exposure, highlighting exceptional environmental stability. This study establishes critical structure-property relationships, revealing that induced porosity, meta-structure effects, large flake size, and optimized surface terminations synergistically enhance EMI shielding. By elucidating the interplay between material parameters and shielding performance, this work provides a foundational framework for designing advanced EMI mitigation technologies, paving the way for scalable, high-performance shielding solutions in next-generation flexible and wearable electronics.

Thin-thickness and lightweight electromagnetic wave (EMW) absorption materials are critically needed for stealth technology in the military stealth field. The special structure of a material is important for improving its good EMW absorption. Herein, a series of porous metal–organic framework-derived LaCo/C-decorated Ti 3 C 2 T x (LaCo/C/Ti 3 C 2 T x ) composites are prepared by carbonization at high temperatures. Impressively, the minimum reflection loss of LaCo/C/Ti 3 C 2 T x –2 is −47.72 dB at 10.26 GHz (thickness 2.3 mm), and the optimal effective absorption bandwidth is 5.45 GHz (thickness 1.9 mm). The excellent EMW absorption properties are due to multiple electromagnetic loss mechanisms, such as polarization loss, magnetic loss, and multiple reflections and scattering. This work provides a new route for the application of Ti 3 C 2 T x -based derivatives.

Aqueous zinc-ion batteries have emerged as a highly promising energy storage technologies due to their abundant resources, high safety, and environmental friendliness. However, the cycle stability of Aqueous zinc-ion batteries is severely constrained by zinc dendrite growth on the anode and accompanying side reactions in the electrolyte. Mitigating this effect is crucial for the large-scale application of zinc-ion batteries, and separator modification is regarded as an effective strategy to address these challenges. Here, a method of modifying the glass fiber composite separator with amino-functionalized MXene (Ti₃C₂Tₓ) is attempted to alleviate these problems. The modified Ti₃C₂Tₓ was uniformly loaded on the surface of glass fiber separator by vacuum filtration to fabricate the composite separator. Systematic characterization and electrochemical testing revealed that the composite separator with an optimal coating loading of 2 mg cm⁻² significantly enhanced battery performance. The cycle life of Zn//Zn symmetric cells were markedly extended at 5 mA cm⁻², and specifically, reached 250 h at 0.5 mA cm⁻², which is about 8 times longer than that of the unmodified glass fiber separator (~ 30 h). Furthermore, the Zn||MnO₂ all-cell based on this composite separator also exhibited a higher capacity retention rate after 1200 cycles compared to the blank separator group. This provides an effective research direction for the design of high-performance Aqueous zinc-ion batteries separators. Graphical abstract

Epoxy composite coating with active corrosion inhibition property was prepared through cathodic electrophoretic deposition with the incorporation of Ti 3 C 2 Tx@Mg-Al layered double hydroxides (LDH) hybrid material . Hydrothermal method was adopted to synthesize molybdate (MoO 4 2− )-intercalated Mg Al LDH, which was self-assembled on the surface of Ti 3 C 2 Tx MXene through electrostatic interaction to improve the zeta potential of the Ti 3 C 2 Tx surface to positive value. Fourier transform infrared spectroscopy , X-ray diffraction, transmission electron microscope, scanning electron microscope, X-ray photoelectron spectroscopy, zeta (ζ) potentials test and uv-vis spectroscopic analysis results showed that Mg Al LDH and Ti 3 C 2 Tx@Mg-Al LDH were successfully prepared and Ti 3 C 2 Tx@Mg-Al LDH had ion exchange property. The prepared LDH and Ti 3 C 2 Tx@Mg-Al LDH were added to electrophoretic paint as anti-corrosive additives. After deposition process of 150 V for 2 min on the P110 steel surface, composite coatings had thicknesses of ~110 μm. Electrophoretic deposition has advantages in controlling coating thickness than traditional spray method. Moreover, Ti 3 C 2 Tx@Mg-Al LDH additive endowed composite coating with active corrosion inhibition capacity through ions exchange property between corrosive medium Cl − and MoO 4 2− in the Mg Al LDH interlayer. Electrochemical impedance spectroscopy (EIS) test results showed that Ti 3 C 2 Tx@Mg-Al LDH/epoxy coating exhibited outstanding corrosion protection property. This research provides a new way of using Ti 3 C 2 Tx MXene in the cathodic electrophoretic paint to prepare active anti-corrosive coating.

In this work, a unique three-dimensional (3D) network NiFeCoP@Ti₃C₂Tₓ composite, consisting of Co, Fe co-doped Ni 2 P (NiFeCoP) nanosheets anchored on Ti₃C₂Tₓ nanosheets via heterojunction, was situ constructed by phosphidizing the NiFeCo-LDH@Ti₃C₂Tₓ precursor. The 3D network structure establishes a 3D conductive network while generating a built-in electric field at the heterointerface, which efficiently accelerates electron/ion transport and simultaneously improves the structure stability of the electrode. DFT calculations demonstrate that Co doping further optimizes the electronic structure of NiFeCoP, introduces additional active sites, thereby promoting electrochemical reaction kinetics. Meanwhile, the synergistic effect among Ni, Fe, and Co with different redox potentials effectively buffers the volume changes during charge/discharge processes. Consequently, NiFeCoP@Ti₃C₂Tₓ as lithium ion batteries (LIBs) anode shows outstanding electrochemical performance at different current density (950 mAh/g after 340 cycles at 0.5 A/g, 816 mAh/g after 900 cycles at 1 A/g, 541 mAh/g after 1000 cycles at 2 A/g).
