Radiation-induced skin injury (RSI) remains a significant clinical challenge due to persistent oxidative stress, chronic inflammation, and impaired tissue regeneration. It is demonstrated that RSI is accompanied by dysregulation of the immune microenvironment, wherein macrophages act as key regulators of all pathological cascades. Here, we developed a dual network hydrogel (Gel/SA@MXene) through dual cross-linking via UV irradiation and calcium ions to accelerate radiation-combined wound healing. The hydrogel provided good biocompatibility, tunable mechanical properties, and controllable degradability by adjusting the composition ratio of GelMA and SA, cross-linking density, and the incorporation of MXene, where SA formed an extensive hydrogen-bonding network with MXene nanosheets to stabilize them and ensure homogeneous dispersion. The optimized hydrogel degraded and supplied MXene nanosheets, which successfully mitigated oxidative stress, promoted macrophage polarization toward the M2 phenotype, and broke the cycle of chronic inflammation. This remodeled immune microenvironment effectively alleviated oxidative damage in radiation-exposed HaCaT skin cells and supported cell migration and proliferation. In addition, in vivo experiments revealed that Gel/SA@MXene significantly ameliorated tissue inflammation and enhanced collagen deposition, thereby facilitating the healing of the skin wounds complicated by radiation injury Overall, this study highlights the potential of Gel/SA@MXene as a multifunctional platform that integrates antioxidant, immunomodulatory, and regenerative functions, effectively transforming the irradiated wound bed from a state of metabolic paralysis to one conducive to healing.

Although MXene has been widely used in many energy storage systems, the absence of a high intrinsic voltage plateau results in its poor discharging feature. Herein, we report a Nb 2 CTx MXene cathode with an apparent discharge voltage plateau for high-performance aqueous zinc ion batteries. Triggered by a repeated high-voltage scanning up to 2.4 V, the Nb 2 CTx cathode gradually displays a stable Zn 2+ storage dominated by a battery behavior. A high discharge voltage plateau of 1.55 V is presented, which is distinct from all reported MXene electrodes. Consequently, a record-level energy density among all aqueous MXenes electrodes of 146.7 Wh kg −1 with a 63% contribution from the plateau region is obtained, which is 292% that of the capacitive Nb 2 CTx electrode. The developed high-voltage scanning strategy is also effective for Ti 3 C 2 T x MXene to achieve a remarkable voltage plateau.

Designing complex multi-interface architectures on photothermal materials—to enhance internal light reflection and absorption while reducing surface reflection—has proven to be an effective strategy for improving light-to-heat conversion efficiency. In this study, a colloid-like thin film with superior photothermal performance was fabricated via a facile method by incorporating γ-glycidoxypropyltrimethoxysilane (GPTS)-modified MXene (S-MXene) into a phenolic resin matrix. The phenolic resin underwent in situ crosslinking with the GPTS modifier grafted on the MXene surface and was rapidly cured under heat, allowing the nanosheets to retain their colloidal dispersion state even within the solidified matrix. In this system, the uniformly dispersed and well-exfoliated S-MXene nanosheets fully exploited their inherently large specific surface area, forming abundant interfaces with the resin matrix. These interfaces facilitated efficient light capture and enhanced light-to-heat conversion via internal multi-interface reflection. Colloid-like films containing 5 wt% of the modified filler and having ∼30 μm thickness exhibited high light-to-heat conversion efficiency (94%) along with favorable optical properties, including negligible transmittance, reflectance below 5%, and imaging clarity comparable to that of colloidal dispersions. Additionally, effective medium theory calculations confirmed that the films exhibited light absorption behavior similar to that of homogeneous or colloidal systems. Furthermore, the encapsulating resin markedly suppressed MXene oxidation, enabling the films to retain over 80% of their initial temperature rise under solar irradiation after six months of ambient exposure. This work presents a scalable and robust strategy for fabricating colloid-like MXene–resin composite films with promising applications in anti-glare coatings, thermal insulation, wearable electronics, and optoelectronic devices.

An electrochemical aptasensor based on Ti 3 C 2 T x (MXene) and cDNA-PAA was established for sensitive detection of aflatoxin B1 (AFB1) in peanuts. The high specific surface area of Ti 3 C 2 T x (MXene) contributed to improve electrochemical efficiency and enhancing sensor stability which were characterized by the Randles−Sevcik equation. The self-made polyacrylic acid (PAA) nanogel was added with aptamer complementary chain (cDNA) to form cDNA-PAA nano gel composite, which could realize the synergistic amplification of the difference between the electrochemical signals before and after the addition of AFB1. The sensing effect of cDNA-PAA was validated using DPV. Methylene blue (MB) was modified at the proximal 3′ termini of the aptamer (Apt-MB), meanwhile AuNPs was used to immobilize Apt-MB and improve the efficiency of electrochemical reactions. The competition between AFB1 and cDNA-PAA combined with Apt MB resulted in a significant change in the electrochemical signal current. In addition, the constructed electrochemical aptasensor had a lower detection limit of 1.0 × 10 −3 ng/L for AFB1 under optimal detection conditions, and a detection range of 1 to 1000 ng/L. Moreover, peanuts with different concentrations of AFB1 were used as actual detection samples. Through the constructed sensor detection, the spiked recovery rates within the spiking range of 50 to 500 ng/mL were 97.76% to 101.84% ( n = 3).

2D MXenes have attracted extensive attentions owing to their anisotropy, high conductivity and other extraordinary properties. The popular preparation method of MXenes usually involves HF in high concentrations, which has seriously restricted their pervasive applications. In this work, a new hydrothermal route with low-toxicity etching agents (NaBF 4 , HCl) was used to synthesize Ti 3 C 2 MXene ( h- Ti 3 C 2 ). Compared with the Ti 3 C 2 prepared by the traditional HF etching method ( t- Ti 3 C 2 ), the h- Ti 3 C 2 has the higher c lattice parameter , larger interlayer distance and larger BET specific surface area, because of the slow release mechanism during the hydrothermal process. The hydrothermal etching method not only avoided the use of high-concentration HF, but also was more efficient to prepare Ti 3 C 2 flakes. Moreover, the hydrothermal etching route can be extended to other MXene materials, e.g. Nb 2 C. We demonstrated that the h -MXenes have better adsorption performance of methylene blue and methyl orange dyes. The hydrothermal etching route proposed in this study enabled the environmental benign and high efficiency exfoliation of MXenes, displaying the promise to facilely prepare 2D MXenes and paving a way to their widespread applications.

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).

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.

One-dimensional (1D) carbon fiber (CF) and two-dimensional (2D) MXene, with high strength and physical barrier properties separately, are expected to simultaneously realize a synergistic reinforcing effect as strengthening fillers in epoxy resin to protect steel structures. However, synergistic reinforcement is significantly limited by the chemical compatibility and dispersing state of fillers in resin due to the chemical inertness of CF and self-stacking properties of MXene. Inspired by the chemical structure of mussel’s foot filaments, Fe 3+ -tannic acid (Fe 3+ -TA) metal-phenolic networks (MPNs) were constructed on the surface of fillers. Herein, the 1D/2D CF/MXene synergistically reinforced coating was designed with enhanced performance by simultaneously incorporating TA/Fe 3+ @CF (TCF) and TA/Fe 3+ @MXene (TMX) into the epoxy matrix. In the coating, 1D TCF could resist impact, and 2D TMX could provide barrier properties. Erosion test results indicate the T(CF+MX)/EP showed a reduction in volume loss by 13.34% and 13.28%, as well as mass loss by 2.11% and 11.59%, respectively, compared to TCF/EP and TMX/EP. The | Z | 0.01Hz of T(CF+MX)/EP stayed at 1.15 × 10 9 Ω cm 2 even following 25 d of immersion under 60 MPa alternating hydrostatic pressure (higher than that of TCF/EP and TMX/EP). This study could provide insights for multiscale fillers design to utilize synergistic reinforcement with enhanced protective performance of coatings.

Background Volumetric muscle loss (VML) leads to severe skeletal muscle dysfunction. While muscle tissue engineering offers a promising strategy, challenges persist due to insufficient neuromuscular innervation and poor reconstruction of neuromuscular junctions (NMJs). Conductive hydrogels can mimic the electrophysiological microenvironment and thus promote structural and functional regeneration, yet commonly used conductive materials still suffer from poor hydrophilicity, non-degradability, and potential cytotoxicity, while their underlying mechanisms remain unclear. Ti 3 C 2 T x MXene, a class of two-dimensional nanomaterials with high conductivity and biocompatibility, shows potential for repairing electroactive tissues. In this study, we developed a novel biomimetic electroactive hydrogel by incorporating Ti 3 C 2 T x MXene nanosheets into adipose-derived decellularized extracellular matrix (adECM). This study aimed to investigate the effects and mechanisms of MXene/adECM hydrogel on muscle regeneration and innervation. Results MXene/adECM hydrogel demonstrated excellent biocompatibility, biodegradability, and conductivity. Compared to the adECM hydrogel, the incorporation of MXene promoted myogenesis, along with increased expression of Desmin, MyoD1, and Myf5. Furthermore, the MXene/adECM hydrogel at the optimal concentration increased the average neurite length by 47.29 μm ( p < 0.05) relative to the adECM group. Transcriptomic analysis combined with a neuromuscular co-culture system indicated that the MXene/adECM hydrogel promoted the formation of neuromuscular junctions (NMJs). The incorporation of MXene upregulated the expression of specific voltage-gated calcium channels at the motor endplate, with transcript levels of Cacna1a and Cacna1s increased to 2.1-fold and 3.1-fold, respectively. It was further observed that calcium signaling was enhanced in the MXene/adECM group, with the peak calcium signal intensity being 2.40 times that of the adECM group. In vivo rat VML model confirmed that, compared to the adECM hydrogel, the MXene/adECM hydrogel promoted an increase in regenerated muscle fiber area, reduced collagen deposition, and elevated the fluorescence intensity of CD31 and Tuj. The co-localization percentage of presynaptic and postsynaptic NMJ markers increased from 27.85 ± 8.69% to 42.21 ± 15.52%. Gait analysis showed significant improvements in print area, swing/stance ratio, and movement velocity. In the MXene/adECM group, the isometric tetanic force (ITF) upon sciatic nerve stimulation was significantly higher than that of the adECM group (0.082 ± 0.012 N vs. 0.057 ± 0.014 N, p < 0.05), approaching the level of the uninjured group. Conclusion Together, these findings demonstrate that the incorporation of MXenes into adECM provides a promising strategy that integrates microenvironmental support with endogenous electrical cues to modulate calcium influx and promote NMJ formation, offering a new paradigm for the treatment of VML. Graphical Study on the therapeutic strategy and underlying mechanism of conductive MXene/adECM hydrogel for volumetric muscle loss (VML) repair. Ti3C2Tx MXene nanosheets were integrated into an adipose-derived decellularized extracellular matrix (adECM) to fabricate a conductive composite hydrogel. Upon implantation, the MXene/adECM hydrogel promoted structural regeneration and reinnervation of the injured skeletal muscle. The bioactive microenvironment and endogenous electrical conductivity facilitated neuromuscular junction (NMJ) formation, accompanied by enhanced calcium influx

Photothermal conversion of CO 2 to methane offers a promising pathway for simultaneous carbon recycling and renewable energy storage. To date, Ni-based catalysts dominate CO 2 methanation. However, their low-temperature activity under photothermal conditions still requires improvement. MTiO 2 derived from Ti 3 C 2 MXene retains its two-dimensional (2D) layered structure and excellent photothermal conversion properties. Herein, we synthesized Ru-Ni@MTiO 2 catalysts through hydrothermal treatment of Ni-impregnated MTiO 2 with controlled Ru loading ( x = 1, 3 and 5 wt%). The optimal 3Ru-Ni@MTiO 2 catalyst achieved a CH 4 production rate of 86.25 mmol·g −1 ·h −1 at 300 °C, which is 1.3-fold higher than that of the Ru-free Ni@MTiO 2 counterpart. The superior catalytic performance stems from the synergistic electronic effect between Ni and Ru and their dual-site cooperation. Electron transfer from both Ru and MTiO 2 to Ni sites elevates the electron density of metallic Ni, which weakens the H-H bond and accelerates the dissociative adsorption of H 2 . Furthermore, Ru loading not only broadens the light absorption range and promotes photogenerated charge separation, but also increases the density of moderate basic sites, thus boosting CO 2 adsorption and activation. This work provides new insights into the design of bimetallic photothermal catalysts for CO 2 methanation.

MXene-based aerogels are promising for electromagnetic interference (EMI) shielding due to their lightweight nature and high conductivity. However, their practical application is often hindered by severe impedance mismatch and excessive secondary reflection. To overcome this limitation, we developed a multifunctional ternary composite aerogel (MTCA) via a synergistic self-assembly strategy. In this architecture, TpPa-1 covalent organic framework (COF) was grown in situ and integrated with MXene nanosheets within a chitosan matrix. The resulting hierarchical porous structure significantly optimizes impedance matching. Consequently, the optimized MTCA achieves an EMI shielding efficiency of 39.93 dB in the X-band, operating via an absorption-dominated mechanism. This performance stems from enhanced interfacial polarization at the MXene/COF heterojunctions and prolonged microwave propagation paths facilitated by multiple scattering within the porous network. Furthermore, the aerogel exhibits multispectral stealth capabilities: it demonstrates low infrared emissivity (ε = 0.50), superior thermal insulation (surface temperature of 28.7 °C under an 80 °C heat source), and effective visual camouflage adaptable to environmental backgrounds. This work presents a robust strategy for designing advanced stealth materials that integrate efficient absorption-dominant EMI shielding with multispectral compatibility.
