Silicon-based materials are the desirable anodes for next-generation lithium-ion batteries; however, the large volume change of Si during the charging/discharging process causes electrode fracture and an unstable solid–electrolyte interphase (SEI) layer, which severely impair their stability and Coulombic efficiency. Herein, a bundle of silicon nanoparticles is encapsulated in robust micrometer-sized MXene frameworks, in which the MXene nanosheets are precrumpled by capillary compression force to effectively buffer the stress induced by the volume change, and the abundant covalent bonds (Ti–O–Ti) between adjacent nanosheets formed through a facile thermal self-cross-linking reaction further guarantee the robustness of the MXene architecture. Both factors stabilize the electrode structure. Moreover, the abundant fluorine terminations on MXene nanosheets contribute to an in situ formation of a highly compact, durable, and mechanically robust LiF-rich SEI layer outside the frameworks upon cycling, which not only shuts down the parasitic reaction between Si and an organic electrolyte but also enhances the structural stability of MXene frameworks. Benefiting from these merits, the as-prepared anodes deliver a high specific capacity of 1797 mA h g–1 at 0.2 A g–1 and a high capacity retention of 86.7% after 500 cycles at 2 A g–1 with an average Coulombic efficiency of 99.6%. Significantly, this work paves the way for other high-capacity electrode materials with a strong volume effect.

Despite the outstanding theoretical capacities of two-dimensional (2D) molybdenum sulfide (MoS2) with low costs, its low conductivity and easy agglomeration greatly impede the business application as anode materials. The heterostructures between 2D MoS2 and Ti3C2 MXene are able to combine the collective superiorities of MoS2 and Ti3C2, thus greatly ameliorating the electrical conductivity and rate capacity through synergistic effects. Herein, we design a simple intercalation–sulfidation strategy for the construction of the TH MoS2/Ti3C2 heterostructures with a compact stacking lamellar structure and investigate the electrochemical sodium storage properties of the composite. In the architecture, fallen leaf-like MoS2 nanosheets with a mixed-phase crystal containing 1T and 2H phases grow tightly on the surface and interlayer of Ti3C2 matrixes. The expanded layer spacing of Ti3C2 as a result of MoS2 insertion can greatly accelerate electronic/sodium ion transport. Meanwhile, 2D Ti3C2 can serve as a strong mechanical support for the composite electrode to provide a buffer space for volume expansion and avoid structural collapse during cycles. Benefiting from these structural advantages, the TH MoS2/Ti3C2 anode reveals higher sodium storage capacity of 743.6 mAh g–1 than bare MoS2 (579.4 mAh g–1) at 0.2 A g–1. Furthermore, the anode exhibits significantly improved battery rate performance with a high sodium storage capacity of 653.3, 539.1, 512.1, 488.7, 439.3, and 586.7 mAh g–1 at 0.2, 0.5, 1, 2, 5, and 0.2 A g–1. Our study provides a unique synthesis route to construct layered heterostructure composites by artificial stacking of different types of 2D materials, which are considered as highly promising electrode materials for sodium-ion batteries (SIBs).

Potassium-ion and sodium-ion batteries (PIBs and SIBs) attract the attention of researchers because of their high earth abundance, low cost, and even similar principle to lithium-ion batteries. MOF-derived transition metal carbide composites are regarded as promising electrode materials because of their high specific capacity and excellent electrochemical activities while equipped with excellent sodiophilic for sodium nucleation and deposition. Therefore, Co 3 C/MXene@C composites with a large specific surface area are designed for both PIBs and SIBs. In detail, the Co 3 C component plays a key role in electrocatalysis of reversible conversion of some components of solid electrolyte interface films, while rich defective carbon and nitrogen content can improve the whole activity of the material. As results, the Co 3 C/MXene@C electrodes deliver an excellent reversible capacity of 236 mA h g −1 with the coulombic efficiency of 98.51% (for PIBs) and 275.9 mA h g −1 with the coulombic efficiency of 98.43% at 200 mA g −1 (for SIBs) after 100 cycles, superior rate performance of 80.6 mA h g −1 and 105 mA h g −1 at 2000 mA g −1 for PIBs and SIBs, respectively. With these outstanding electrochemical performances , the Co 3 C/MXene@C electrodes show a potential application prospect for potassium-ion and sodium-ion batteries.

Silicon (Si) shows great potential for lithium-ion batteries (LIBs) due to its high theoretical capacity and low working potential. However, its intrinsic low electronic conductivity and large volume expansion during lithiation result in dramatic capacity fading and poor rate capability. Herein, a dual-confinement strategy is proposed for improving the lithium storage properties of Si by uniformly anchoring Si nanoparticles within a MXene/ZIF-8 derived carbon framework. In the Si/MXene@C composite, Si nanoparticles tightly bond with MXene and carbon through the formed interfacial Si–O–Ti and Si–C bonds, respectively, which is beneficial for alleviating the volume expansion of Si and promoting the interfacial charge transfer. Therefore, the Si/MXene@C composite exhibits excellent lithium storage performances in terms of high capacity (1006.1 mAh g–1 at 100 mA g–1), stable cycle performance (862.9 mAh g–1 after 150 cycles at 100 mA g–1), and superior rate capability (233.3 mAh g–1 at 5 A g–1), indicating its promising potential as an anode material for next-generation high-performance LIBs.

Postharvest decay of fresh fruits, driven by water loss and microbial colonization, remains a critical global challenge. Herein, we engineered a microenvironment-responsive biomimetic hydrogel featuring a physical-chemical dual-defense mechanism for zero-additive fruit preservation. This dynamic polymer network (Poly (vinyl alcohol) (PVA)/cationic chitosan/glycerol) securely anchors two dimension Vanadium carbide (2D V 2 C) MXene nanozymes. Macroscopically, a glycerol-driven hydrogen-bonding network endows the hydrogel with dynamic morphological adaptability, conforming to fruit shrinkage to lock moisture and eliminate bacteria-invading micro-cracks. Microscopically, the V 2 C nanozymes act as an intelligent H 2 O 2 -responsive system, capturing trace endogenous H 2 O 2 from microbial metabolism to trigger localized, lethal reactive oxygen species (ROS) storms without exogenous chemicals. In vivo evaluations on cherries and mandarins demonstrated that the P 90 VC 10 G coating maintained weight loss below 10% and total viable counts below 3.43 Lg CFU/g after 9 days of storage at ambient temperature. This work provides a promising protective strategy for sustainable postharvest management.

The use of inorganic nanomaterials as “building blocks” and organic components as “mortars” to build nanocomposites are particularly well-suited to optimize the performance of composites. Here, based on nacre-inspired thought, a novel strategy of fabricating a steady and function tunable three-dimensional MXene thermal conductive cross-linking network skeleton featured by silica (SiO 2 ) nanoparticles bridge was reported, which is constructed in the carboxymethylated cellulose nanofibril (CNF) nanocomposites for facilitating thermal management capability property. Benefited from the strong hydrogen bonding interactions, the thermal conductive fillers of SiO 2 @MXene are able to uniformly disperse and reduce the agglomeration. SiO 2 nanoparticles are uniformly attached to the MXene interlaminar by in-situ method, which is crucial to provide fast conduction channel for heat. The maximum in-plane thermal conductivity value of the SiO 2 @MXene/CNF nanocomposite film increased form 5.0 W·m −1 ·K −1 to 26.4 W·m −1 ·K −1 with introducing 2 wt% SiO 2 nanoparticles, accompanied by 5.28 times higher than that of pure CNF film and 436% increase in in-plane conductivity, which indicates that SiO 2 nanoparticles are bridged to each thermal transport paths to reduce the interface thermal resistance within CNF-based nanocomposite film. In addition, the cooperative interaction effect of MXene nanosheets and SiO 2 nanoparticles in constructing the controllable structural of cross-link framework is contributed to conspicuous improvement of thermal conductivity and flame retardancy. It is worth noting that the effective protective layer formation of SiO 2 nanoparticles after the combustion process, simultaneously thermal stability at high temperature which with residue yield (88.70 wt%) of the nanocomposite film, and achieved for a distinguished flame resistance in practical application. Bioinspired thought engineering has become an emerging and promising thought, this type of multifunctional nanocomposite film is highly promising to be a competitive candidate in the fireproof thermal management field and provides an excellent platform for preparing assembled by other polymeric thermal-management materials.

Developing triethylamine gas sensors with high sensitivity, fast response, superior selectivity, and room-temperature operability has long been a challenge. By correlating the mass of the adsorbed molecules to the resonance frequency, the resonant microcantilevers show promising potential for room-temperature gas detection. In this work, we present a novel MXene@ZnIn2S4 two-dimensional heterostructure with abundant sulfur vacancies as a sensitive material for efficient triethylamine detection. Compared with gas sensors constructed from pure 2D MXene and 2D ZnIn2S4 nanosheets, the MXene@ZnIn2S4 gas sensor exhibits significantly improved sensitivity. The MXene@ZnIn2S4 sensor achieves a high sensitivity variation of 16.1 Hz for 500 ppb triethylamine and demonstrates high selectivity, a low detection limit (5 ppb), and effective moisture resistance. Multiple in situ characterizations and thermodynamic analyses reveal that this remarkable gas sensing capability arises from the distinctive heterojunction, the abundance of active sites induced by surface sulfur vacancies, and the outstanding adsorption thermodynamics of MXene@ZnIn2S4. The combination of a 2D@2D heterostructure and microcantilever sensor paves the way to develop high-performance room-temperature gas sensors.

The rapid evolution of wireless technologies has intensified electromagnetic (EM) pollution, promoting the application of advanced multifunctional shielding materials. Herein, we developed aramid fiber (AF) based composite fabrics by sequentially loading Ti 3 C 2 T x MXene nanosheets and silver nanowires (AgNWs) onto fabric substrates. The optimized AF/MXene/AgNWs structure exhibits exceptional electromagnetic interference (EMI) shielding effectiveness of 63.93–96.75 dB in the X-band, coupled with superior shielding efficiency (SSE/t) of 3995–5183.03 dB cm 2 g −1 at a thickness of 0.34 mm. This performance stems from synergistic conductive networks formed by MXene and AgNWs, enabling multi-scale EM wave attenuation through reflection, ohmic loss, and interfacial polarization. Beyond EMI shielding, the composite demonstrates integrated multifunctionality including infrared stealth capability, rapid electrothermal response, precise photothermal regulation, antibacterial efficacy, and flame retardancy. The encapsulation of polydimethylsiloxane (PDMS) further ensures environmental stability, and the fabrics maintained 94.3 % EMI shielding (48.93 dB) after 30 days of oxidation. The EMI shielding efficiency was maintained at 47.98 dB after salt-spray corrosion for 48 h. With excellent mechanical flexibility, this multifunctional fabric presents significant potential for next-generation wearable electronics, medical thermal therapy systems, and aerospace applications.

Intelligent wearable devices based on laser-induced graphene (LIG) have attracted significant attention for human health monitoring. This paper proposed an innovative all-in-one design for preparing a self-powered smart insole using laser-induced MXene-composited graphene hybrid (LIG@MXene) from lignocellulose precursor. By incorporating MXene into the LIG, the composite achieved improved crystallinity and reduced defects, contributing to the electrical conductivity (17.2 Ω∙sq −1 ) and structural stability. The optimal laser processing parameters are 55% for laser power and 70 mm s −1 for etching rate. The optimized LIG@MXene composite functions as a versatile platform for integrating triboelectric nanogenerator (TENG) with a high output power of 35 V cm −2 , supercapacitor with a superior areal capacitance of 71.4 mF cm −2 and the excellent cycling stability of 89.5% retention, Joule heater of the maximum heating temperature of 113 °C at 5 V, and various flexible sensors for pressure, humidity and sweat composition with high sensitivity and linearity. In particular, the minimum L-tyrosine limit of detection in sweat is only 9.60 µM. These functional modules are embedded within an insole via a direct laser writing technology, which only emitted 9.10 kg CO 2 eq during manufacturing. The direct laser-patterned synthesis of LIG@MXene composite represents a significant step forward in advancing smart wearable electronic devices.

Covalent solvent-free nanofluids show excellent tribological properties, yet the effect of organic shell chain length on performance remains unclear. This work innovatively synthesized three MXene-based nanofluids (M1000 NFs, M2070 NFs, M3085 NFs) with tuned canopy chain lengths, revealing chain-dependent performance. Short-chain M1000 NFs achieved superior oxidative stability in water through dense surface grafting, maintaining performance over 180 days. As a water-based additive, M3085 NFs with extended chains reduced friction by 74% at 0.25 wt% via an optimized adsorption layer. Wear resistance depended mainly on MXene core concentration rather than chain length. These insights provide key design guidelines for high-performance aqueous MXene nanofluids, particularly addressing the coupled challenges of oxidative degradation and friction control.

The synergistic contamination of uranium and organic pollutants in complex aquatic systems significantly complicates environmental remediation efforts and poses substantial threats to ecosystems and human health. This study presents a self-driven photocatalytic fuel cell (SDPFC) that achieves coordinated uranium recycling, organic degradation, and electricity generation through the innovative integration of cobalt-based composite cathodes and semiconductor photoanodes. The system’s primary innovation lies in constructing dual functional catalytic interfaces using a MXene supported cobalt nanoparticle-embedded nitrogen doped carbon cathode (Co-N x /C@MXene) coupled with TiO 2 nanoarray/silicon photovoltaic cell hybrid photoanodes. The engineered Co-N x /C@MXene composite cathode demonstrates enhanced performance through MXene’s abundant surface functional groups enabling U(VI) enrichment, complemented by nitrogen-cobalt co-doping architecture that significantly improves charge transfer efficiency, thereby accelerating the hexavalent uranium reduction kinetics. Notably, under natural sunlight irradiation, the removal efficiencies of SDPFC for both U(VI) and tetracycline hydrochloride (TCH) remained above 94%. Even after 10 consecutive cycles, SDPFC continued to exhibit high removal efficiencies and excellent cyclic stability for both pollutants. This work overcomes the technical limitations of conventional wastewater treatment technologies in systems with multiple contaminants, proposing an innovative energy recovery catalytic strategy that establishes a new paradigm for radioactive wastewater management.
