Layered MXene-based magnetoelectric composites have been extensively investigated and applied as microwave absorbing (MA) materials. Although multicomponent composite strategies have been proven to significantly improve the MA performance of materials, the fine structural design and optimization of the functional synergy of absorbers at intricate environments remain scientific issues worthy of further exploration. In this study, FeCo@C/Ti3C2Tx MXene composites were synthesized through a combination of chemical vapor deposition and electrostatic self-assembly techniques. The core–shell structure of ultrafine FeCo@C nanoparticles, with an average diameter of 13.51 nm, has effectively mitigated the adverse effects of harsh environmental conditions due to chemical stability of the carbon layer. Furthermore, the integration of ultrafine FeCo@C nanoparticles with a low filler loading contributed to the overall lightweight characteristic. Notably, the FeCo@C/Ti3C2Tx MXene composites with a 20 wt % filling ratio exhibit a minimum reflection loss (RLmin) of −31.6 dB at 1.7 mm and an effective absorption bandwidth of 5.76 GHz at 2.4 mm. The corresponding absorbing coating achieves a maximum reduction in the radar cross-section of 18.86 dBm2. The FeCo@C/Ti3C2Tx MXene composites exhibit the potential for applications in challenging environments, including high-temperature and humid conditions.

Benefiting from the unique chemical properties and the adjustable layered spacing, MXenes have been paid more attention to the field of energy storage and conversation, especially towards constructing hybrid structure for the use of Li-ion battery anodes. However, most MXene-based composites are achieved by the ex-situ mixing method on the basis of acid-etched MXene, which makes it extremely hard to maintain a good structural stability in the service process. Herein, we proposed a novel one-step in-situ strategy, i.e. SnCl 2 molten salt reaction with Ti 3 AlC 2 for synthesizing Sn-nanoconfined Ti 3 C 2 T x MXene composites. During the synthesis process, SnCl 2 not only executed as the Lewis acid to etch Ti 3 AlC 2 for obtaining Ti 3 C 2 T x MXene, but could also be in-situ transformed to Sn nanoparticles confined between the Ti 3 C 2 T x MXene layers. The 2D layer-confined effect inhibited the spontaneous coarsening of metal Sn at high temperature as well as the huge volume expansion during the electrochemical cycles. Meanwhile, the in-situ formed Sn nanoparticles as pillar played a decisive role in enlarging interlayered active spacing of Ti 3 C 2 T x MXene for Li-storage. As a result, the surprising enhancement of electrochemical Li-storage performances could be achieved during long-term cycling. This work provides a novel route to explore the application of MXene based on the molten salt methods.

The two-dimensional nano MXenes have unique microstructures and physicochemical properties, showing great potential in enhancing or replacing traditional metal processing lubricants. Here, a stable oil-in-water emulsion was constructed by coassembling Ti3C2TX MXene modified with phosphonic acid containing C10 alkyl chain and Tween 80 at the oil–water interface. The emulsion exhibits efficient friction-reducing and antiwear performance as well as corrosion resistance. The effect originates from the formation of a physical adsorption film and tribochemical reaction film stabilized by the interlocking of long carbon chains on the friction interface. This study provides a model of “material functionalization-interface synergy” for developing metal processing lubricants.

Suppressing secondary electromagnetic reflection while maintaining high shielding effectiveness remains a central challenge for conductive MXene-based electromagnetic interference (EMI) shields. Here, 2D/0D MXene/BaFe 12 O 19 nanostructures were constructed by electrostatic self-assembly. The assembly combined negatively charged MXene nanosheets with poly(diallyldimethylammonium chloride) (PDDA)-functionalized BaFe 12 O 19 nanoparticles. This surface-charge-mediated assembly suppresses MXene restacking, creates dielectric–magnetic heterointerfaces, and systematically regulates the complex permittivity and permeability. The incorporation of BaFe 12 O 19 moderates the excessive permittivity of MXene and introduces resonance-type magnetic loss. These interrelated effects thereby alleviate the dielectric–magnetic imbalance, allowing more incident electromagnetic energy to enter and be attenuated within the shield. At a thickness of 1 mm paraffin-based toroidal specimen, MXF-3 reaches a maximum total shielding effectiveness (SE T ) of 58.0 dB at 10 GHz, with an absorption shielding effectiveness (SE A ) = 48 dB and reflection shielding effectiveness (SE R ) = 10 dB. Spin-polarized density functional theory calculations reveal orbital coupling and static charge redistribution at the MXene/BaFe 12 O 19 interface, providing electronic-structure insight into the interfacial interactions. These results demonstrate that electrostatic self-assembly is an effective route for preparing powder-based MXene/hexaferrite functional fillers for X-band EMI shielding.

Since the p53 protein is an important promising biomarker of lung tumor and colorectal tumor, it is very essential to design a highly effective mean to monitor the degree of p53 for the early clinical analysis/therapy of the related tumors. In this work, a sandwich-type electrochemical immunosensing (SES) platform is proposed for the first time to detect p53 via synthesizing Ti 3 C 2 T x MXene nanoribbons (Ti 3 C 2 T x Nb) and ferrocene/gold nanoparticles (Fc/Au) respectively as the sensing substrate and signal-amplifier. The superior electrical property and large surface area of Ti 3 C 2 T x Nb are beneficial to assemble the initial p53-antibodies (Ab 1 ), while the synthesized Fc/Au is devoted to assemble the secondary p53 antibodies (Ab 2 ) and gives a magnified signal. By adopting the Fc molecules as the probes, the experiments reveal the response current of Fc resulted from the SES structure increases along with the p53 increase from 1.0 to 200.0 pg mL −1 . A considerable low detection limit (1.0 pg mL −1 ) is achieved after optimizing several key conditions, it is thus confirmed the as-proposed SES mean exhibits significant application in the detection of p53 protein and other targets.

With the proliferation of electronic devices and wireless technologies, Electromagnetic Interference (EMI) has become a critical global concern. Correspondingly, the development of efficient EMI shielding materials with strong electromagnetic wave absorption and reflection is imperative. This study presents the fabrication of sandwich-structured composite films (SCFs) utilizing regenerated cellulose (RC) as the matrix, incorporating Ti 3 C 2 T x MXene and Fe 3 O 4 nanoparticles (Fe 3 O 4 NPs) as functional fillers. The SCFs (MXene/RC-Fe 3 O 4 /RC-MXene/RC) were fabricated using an immersion phase conversion method followed by mechanical pressing techniques. The resulting SCFs exhibit a conductivity of 23.8 S/m and a maximum EMI shielding effectiveness (SE) of 32.52 dB. This performance is attributed to the innovative sandwich architecture, which employs a “reflection-absorption-reflection” mechanism to attenuate electromagnetic waves. In addition, MXene is effectively dispersed in the cellulose matrix, enhancing the mechanical properties of the composite films. Notably, increasing the MXene content from 10 wt% to 40 wt% resulted in a tensile strength increase from 9.42 MPa to 17.10 MPa. This research elucidates a robust and scalable approach for the development of advanced electromagnetic shielding materials.

Developing flexible materials with combined electromagnetic interference (EMI) shielding and microwave absorption capabilities holds significant application potential. Ti 3 C 2 T x MXene has emerged as a flexible EMI shielding material due to its thinness, adhesion, flexibility, and dual shielding and absorption properties. High conductivity-induced reflection and layered self-stacking challenges hinder Ti 3 C 2 T x MXene performance enhancement, posing challenges demanding solutions. This study first uses simulations to analyze how functional group modifications and interlayer spacing affect Ti 3 C 2 T x MXene's electromagnetic properties. Hydroxyl groups are proposed as key regulators of Ti 3 C 2 T x MXene's properties. Subsequently, Ti 3 C 2 T x MXenes were treated with a low-concentration NaOH gradient to modulate hydroxyl groups. Ultrasonic-microwave extraction resolved delamination, enabling ultra-thin film preparation. The treatment caused hydroxyl groups to initially increase and then decrease, with interlayer spacing first contracting and then expanding, achieving synchronous modulation of Ti 3 C 2 T x MXene's surface functional groups and interlayer spacing. The EMI shielding and microwave absorption of ultrathin films were analyzed, with shielding efficiency correlating positively with hydroxyl group concentration. Ti 3 C 2 T x MXene treated with 0.2 mol/L NaOH exhibited maximum hydroxyl concentration, achieving 48.965 dB shielding at 0.016 mm thickness (SE/t = 3060.320 dB/mm), demonstrating hydroxyl groups' role in improving shielding performance. Wave absorption increased with higher NaOH concentrations, correlating with surface hydroxyl groups. The 0.3 mol/L NaOH-treated MXene showed a 12.883 dB absorption increase versus untreated samples. Additionally, the green shielding index (g s ) of Ti 3 C 2 T x MXene films increased by 32.9 % with higher NaOH concentration. Results demonstrate that surface hydroxyl modification and layer spacing adjustment significantly enhance the EMI shielding and wave absorption of Ti 3 C 2 T x MXene. Meanwhile, the prepared thin, flexible products have potential applications in aerospace, defense, and flexible electronics.

Developing high-performance and cost-effective microwave-absorbing materials for large-scale production is crucial in addressing the current electromagnetic pollution problem. This has become a focus of scientific research. This study proposes a cost-effective freeze-thaw method to enable large-scale production of MXene-based flexible films. This method streamlines the preparation process and produces ultrathin flexible MXene/CNF composite films with a multidimensional layered structure. The multidimensional layered structure provides additional scattering and reflecting paths for electromagnetic waves, increasing the interaction time between electromagnetic waves and the material. Additionally, the redistributed interfacial charge enhances the dielectric loss and electromagnetic shielding performance for the shielding material, thereby improving microwave absorption efficiency. Owing to these advantages, the MXene/CNF composite films prepared using the freeze-thaw method exhibit excellent electromagnetic shielding and mechanical properties. The conductivity of the composite film can reach 165.9 S cm −1 with a shielding effectiveness of 54.7 dB, and a high efficiency of 99.74 %. According to the simulations using a finite element method (FEM), the arrangement and rotation angles of all CNF layers significantly affect the electromagnetic shielding effectiveness of the MXenen/CNF composite films.

Metal-organic frameworks (MOFs) are regarded as potential candidate materials with great application prospects in the field of gas sensing. In this study, MOF derivatives were anchored onto MXene sheets through self-assembly technology to prepare a heterojunction material ZnO/Ti 3 C 2 T x MXene with high specific surface area, achieving ultrafast dual gas sensing behavior for H 2 /NO 2 . At a low temperature of 80°C, the ZnO/ Ti 3 C 2 T x MXene heterojunction sensor exhibited an ultrafast response (23.17%) to 500 ppb H 2 within 3.2 s. After a moderate temperature increase to 180°C, it also demonstrated significant sensing performance (46.3%) to 500 ppb NO 2 within 4 s. The electronic interaction mechanism of ZnO/ Ti 3 C 2 T x MXene heterostructures in H 2 and NO 2 detection was revealed through density functional theory calculations and in-situ Raman spectroscopy, clarifying the influence of interfacial charge transfer on sensing performance. Heterogeneous structures achieve the regulation of gas adsorption-induced electron rearrangement and carrier modulation by constructing interface charge-regulating channels, significantly enhancing the response rate, selectivity and reversibility in the detection of H 2 and NO 2 , thereby enabling highly sensitive and trace detection of the two gases.

Herein, we fabricate the anisotropic polyimide (PI)/Ti 3 C 2 T x MXene composite aerogels with highly elastic mechanical performance and outstanding flame retardancy, thermal insulation and oil absorption properties via an unidirectional freeze drying method. The introduction of strong hydrogen bonding interactions between Ti 3 C 2 T x and PI matrix is beneficial to the structure integrity and mechanical properties of the composite aerogels. The samples show excellent mechanical properties along the axial direction and highly elastic properties along the radial direction. The compressive modulus and strength of the T 1 P 4 composite aerogel are 5.16 and 0.55 MPa, respectively, and only the minimal plastic deformation and low energy loss coefficient can be observed for the composite aerogel even after 500 compression cycles. Moreover, the PI/Ti 3 C 2 T x composite aerogels has low thermal conductivity, superior flame retardancy and thermal insulation, and excellent oil absorption properties. The surface temperature is 40.6 °C for the T 2 P 1 composite aerogel with 15 mm thickness after annealing on the hot stage at 180 °C for 5 min. The water contact angle of the T 1 P 4 composite aerogel is 123°, and the oil absorption capacity of lubricant oil is 1126%. Furthermore, the composite aerogel exhibits stable oil absorption capacity even after 50 cycles, which demonstrates great potential for practical applications in cyclic oil absorption.

Ti 3 C 2 T x can be released into the groundwater environment due to its widespread application. It poses a severe environmental risk due to its cytotoxicity but has received little attention. In the groundwater, the dynamic groundwater flow and solution chemistry will affect the transport behavior of Ti 3 C 2 T x which is still unclear and necessary for the assessment of its environmental impact. Thus, this study investigated the influential mechanisms of groundwater flow and solution chemistry on the transport of Ti 3 C 2 T x by considering its 2D shape and degradation characteristics via column experiments with numerical models. The results showed that the transport of Ti 3 C 2 T x in the quartz sand column significantly increased with the decrease of ionic strength (IS) and increase of pH and sodium humate. Face-on oriented Ti 3 C 2 T x particles were reversibly attracted in the secondary minimum, whereas edge-on orientation favored the irreversible attachment in the primary minimum that was facilitated by the nanoscale charge heterogeneity. The retention of Ti 3 C 2 T x significantly increased during the FI period due to the enhanced residence time, facilitating edge-on attachment by diffusion and diffusion into stagnation zones. This study demonstrated the controlling roles of the shape and degradation characteristics of Ti 3 C 2 T x on its mobility, suggesting that such unique properties should be considered in assessing the environmental fate of emerging nanoparticles.

Under the background of sustainable energy development, the development of efficient, stable and low-cost electrocatalysts to improve electrochemical performance has become a research hotspot in the field of energy conversion. In this work, upright, one-fold and oblique Ni nanorods were designed and grown on Ti 3 C 2 T x MXene nanosheets via glancing angle deposition technique of physical vapor deposition. For the hydrogen evolution reaction, the composite Ti 3 C 2 T x @upright exhibited a low overpotential of only 131 mV@10 mA/cm 2 , along with excellent 24 h stability in 1 M KOH. Its excellent performance is mainly attributed to the high porosity of the upright nanorods, the fast electron transport channels provided by Ti 3 C 2 T x MXene, and the stable interface structure. This research provides new ideas for constructing high-performance electrocatalytic catalysts and achieving efficient electrocatalytic conversion in sustainable energy systems.
