Lithium-sulfur batteries (LSBs) are considered promising candidates for next-generation battery technologies owing to their outstanding theoretical energy density and cost-effectiveness. However, the low conductivity and polysulfide shuttling effect of S cathodes severely hamper the practical performance of LSBs . Herein, in situ-generated single layer MXene nanosheet/hierarchical porous carbonized wood fiber (MX/PCWF) composites are prepared via a nonhazardous eutectic activation strategy coupled with pyrolysis-induced gas diffusion. The unique architecture, wherein single layer MXene nanosheets are constructed on carbonized wood fiber walls, ensures rapid polysulfide conversion and continuous electron transfer for redox reactions. The C–Ti–C bonds formed between MXene and PCWF can considerably expedite the conversion of polysulfides, effectively suppressing the shuttle effect. An impressive capacity of 1301.1 mA h g −1 at 0.5 C accompanied by remarkable stability is attained with the MX/PCWF host, as evidenced by the capacity maintenance of 722.6 mA h g −1 after 500 cycles. Notably, the MX/PCWF/S cathode can still deliver a high capacity of 886.8 mA h g −1 at a high S loading of 5.6 mg cm −2 . The construction of two-dimensional MXenes on natural wood fiber walls offers a competitive edge over S-based cathode materials and demonstrates a novel strategy for developing high-performance batteries.

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.

Ti 3 C 2 QDs with good water solubility and photoluminescence properties was prepared by nitrogen and phosphorus doping (N,P-Ti 3 C 2 QDs). The probe has a fluorescence emission peak at 420 nm and emits bright blue fluorescence, which can distinguish and detect two antibiotics with similar structures, chlortetracycline (CTC) and tetracycline (TC). The fluorescence enhancement effect can be realized by the interaction with CTC. The linear range is 2–22 μM, and the detection limit is as low as 0.53 μM. And the change of fluorescent color from bright blue to bright purple can be observed with the naked eye. At the same time, with the addition of TC, the fluorescence of N,P-Ti 3 C 2 QDs can be quenched by static quenching effect, and the fluorescence color changes from bright blue to yellowish green. The detection range is 4.1–20.5 μM, and the detection limit is as low as 0.16 μM.Therefore, on this basis, a strategy for simultaneous detection and recognition of CTC and TC is proposed. The method has been successfully applied to the determination of CTC and TC in milk samples. This paper provides a new detection method for the identification of tetracycline antibiotics and taps the application potential of Ti 3 C 2 QDs in food detection.

Photocatalytic conversion of CO 2 into a special chemical fuel with high yield and selectivity is still a major challenge. Herein, a 3D hierarchical NiAl-LDH/Ti 3 C 2 MXene (LDH/TC) nanocomposite is constructed through in situ loading of Ti 3 C 2 nanosheets on the NiAl-LDH scaffold during the hydrothermal process. The formation of a uniform and well-defined 2D/2D heterogeneous interface can be realized by optimizing the ratio of Ti 3 C 2 and the precursors for NiAl-LDH. The 3D hierarchical scaffold with high specific surface area contributes to the favourable photon adsorption and utilization. The intimate contact between Ti 3 C 2 and NiAl-LDH with numerous interfaces effectively promotes the separation of the photoinduced electron-hole pairs in NiAl-LDH. Together with the highly exposed oxidation–reduction active sites and the enhanced CO 2 capture and activation. The maximum photocatalytic CO production rate on NiAl-LDH/Ti 3 C 2 reaches 11.82 μmol g −1 h −1 with 92% selectivity and superior stability. This work provides an effective approach for the development of an ideal photocatalyst by collaborative utilization of materials with different dimensionalities.

Hydrogels characterized by a three-dimensional polymer network are promising vehicles for oral colon-targeted drug delivery, yet conventional systems relying on intragastric cross-linking agents face clinical limitations. Here, we present a cross-linker-independent oral in situ hydrogel (CCS/CMC-Na) functionalized with Ti₃C₂ MXene nanosheets for optimized inflammatory bowel disease (IBD) therapy. The CCS/CMC-Na hydrogel exhibits a liquid-gel state transition in simulated gastric fluids while gradually returning to a liquid state in simulated colonic fluids, enabling precise targeting of inflamed colon tissues and protecting encapsulated drugs from gastric degradation. The integration of Ti₃C₂ not only enhances mechanical stability but also introduces multifunctional therapeutic capabilities: repairing all levels of intestinal barriers, reducing oxidative stress, inhibiting apoptosis, modulating Regulatory T cells (Treg)/T helper 17 (Th17) cell differentiation and NF-κB/IκB inflammatory pathway, and remodeling the intestinal microbiota. In murine models of acute and chronic colitis, Ti₃C₂@CCS/CMC-Na significantly alleviates disease severity, outperforming clinical first-line drug 5-ASA. Crucially, this system eliminates the need for dual-tube administration, simplifies dosing protocols, and demonstrates excellent biocompatibility over 50 days, addressing key challenges in current IBD therapies. By integrating precise targeting, multimodal therapeutic actions, and scalable fabrication, Ti₃C₂@CCS/CMC-Na represents great clinical translational potential, offering a safer and more effective treatment option for IBD.

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.

With the rapid development of communication technology and portable electronic devices, the demand for the design of electronic devices with superior electromagnetic interference shielding and fire safety performance is increasing. Herein, epoxy resins (EPs) with typical segregated networks were designed by emulsion polymerization and adhesion self-assembly strategies and novel polyphosphonitrile microspheres (PZS) synthesized by precipitation polymerization were used to improve the fire safety of EP composites . It is worth noting that the oil-water (EP to water) ratio in emulsion polymerization is closely related to the microscopic morphology of the segregated network. A smaller ratio of EP to water results in more paths for electrical charge transfer through the EP composites. As a result, EP/PT-3 with a minimum oil-to-water ratio exhibits a high EMI SE (electromagnetic interference shielding effectiveness) in the X-band ranging from 40.12 to 40.30 dB at a loading of 7.20 vol% Ti 3 C 2 Al x . Besides, the synergistic action of the adjustable Ti 3 C 2 Al x network with PZS endows EP superior flame retardant performance. Compared with EP, the PHRR and THR values of EP/PT-3 are down 55.7 % and 72.6 %, respectively. There is no doubt that EP/PT-3 has provided a new route for the preparation of Ti 3 C 2 Al x -based electromagnetic shielding and fireproof materials.

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.

Ti(C,N)-based cermets are widely used in cutting tools and high-temperature structural components, but their application is limited by difficulties in fabricating large and complex-shaped parts. In this study, Ti(C,N)-based cermets were prepared via gel-cast using a CoCrCuFeNi high-entropy alloy (HEA) as the binder. The effects of solid loading on slurry stability and green body formation, as well as the influence of sintering temperature on microstructure and mechanical properties, were investigated. The results show that stable slurry and uniform green bodies were obtained at a solid loading of 55 vol%. With increasing sintering temperature, densification and mechanical properties improved concurrently, while the fracture mechanism transitioned from intergranular fracture to matrix tearing. The Ti(C,N)-based cermet sintered at 1550 °C for 60 min exhibited excellent properties, with a relative density of 96.42%, hardness of 1665.67 HV30, bending strength of 671.75 MPa, and fracture toughness of 6.44 MPa m 1/2 , comparable to conventional Ti(C,N)-Ni cermets. These results demonstrate that gel-cast with a HEA binder is a promising approach for fabricating large, complex-shaped Ti(C,N)-based cermets.
