Photothermal membrane distillation (PMD) presents a promising, eco-friendly and low-cost solution to address water shortage. Current PMD is still challenged by low solar energy utilization, limited mass transfer rate, poor membrane stability, and serious membrane fouling. Herein, we demonstrate that Ag@MXene heterojunction engineered membranes can achieve efficient desalination through photothermal membrane distillation. Theoretical calculations and experimental results prove that the plasmonic coupling effect of Ag@MXene enhances solar-thermal conversion efficiency, due to the promoted relaxation of photoexcited hot carriers. Meanwhile, the heterojunction structure promotes water molecules transfer within the interlayer channels. Consequently, the membrane achieves a significantly boosted total freshwater production rate (2.62 kg m −2 h −1 ) with a significant enhancement percent of 83.2 % and a high photothermal efficiency (77.0 %) under one solar illumination. Moreover, the Ag@MXene membrane possesses a superior durability in 72 h of continuous seawater desalination with an impressive ion removal efficiency of 99.95 %. The PMD membrane achieves a peak flux and an average flux of 21.53 and 12.08 kg m −2 h −1 in the outdoor test. This work offers a new approach for heterojunction engineered PMD membranes toward energy-efficient and sustainable freshwater production.

Multifunctional integrated electromagnetic wave absorption (EMA) materials have been widely concerned. In this work, CoNi/MXene@Wood was prepared by carbonizing natural wood at high temperature and introducing CoNi and Ti3C2Tx MXene into its rectangular honeycomb unit by hydrothermal reaction and vacuum impregnation. Due to the reasonable control of structure and composition, CoNi/MXene@Wood can be employed for both electromagnetic protection and infrared stealth. CoNi/MXene@Wood-1.5 displays excellent EMA performance with a minimum reflective loss (RLmin) of −56.8 dB and the effective absorbing bandwidth (EAB) covering the entire X-band. Besides, with low and stable thermal conductivity (0.219-0.267 W m-1 K-1) over a temperature range of 298-673 K, the CoNi/MXene@Wood can realize the thermal infrared stealth of protected targets in different environments. The structure design and dielectric constant adjustment provide strategies for obtaining high EMA performance materials with infrared stealth.

The convergence of energy storage and sensing functionalities in a single miniaturized device represents a critical advancement for next-generation wearable electronics. Herein, we report an MXene/GO@MnO2 composite with a rationally designed layer-by-layer architecture for planar microsupercapacitors (PMSCs) and capacitive microsensors. By intercalating MnO2-decorated graphene oxide (GO@MnO2) between MXene layers, the interlayer spacing is expanded to 1.47 nm, enabling ultrafast ion diffusion (DLi+ = 3.1 × 10–12 cm2 s–1) and efficient vertical electron transport (σ⊥ = 247.7 S m–1). The resulting PMSCs achieve record-high areal capacitance (39.3 mF cm–2) and energy density (2.0 μWh cm–2) among MXene-based microdevices, with 91.1% capacitance retention after 10,000 cycles. As a wearable sensor, the device demonstrates multisignal detection capability, including temperature (10–40 °C, sensitivity = 6.3% °C–1), pressure (sensitivity >1.0 kPa–1, response time <10 ms), and biomechanical motions. This work provides a paradigm for designing multifunctional microsystems through strategic interlayer engineering of 2D materials.

In this study, copper (Cu) nanoparticles (NPs)-modified Ti 3 C 2 T x MXene nanosheets (Ti 3 C 2 T x @Cu) were synthesized via chemical reduction. Subsequently, Ti 3 C 2 T x @Cu/Cu composite powder was synthesized via low-energy ball milling, followed by rapid hot pressing to fabricate Ti 3 C 2 T x @Cu/Cu composites. The influence of Ti 3 C 2 T x @Cu content on the microstructure, mechanical properties, and tribological performance of Ti 3 C 2 T x @Cu/Cu composites was systematically investigated. With increasing Ti 3 C 2 T x @Cu content (0–10 vol%), the Brinell hardness of the composites gradually increased, while the tensile strength showed an initial increase to a maximum of 311.59 MPa at 3 vol%, and then gradually decreased. The main reason for this improvement was the enhancement effect of Ti 3 C 2 T x @Cu. Moreover, Ti 3 C 2 T x @Cu effectively enhanced the tribological performance of the Cu matrix, attributed to the synergistic effect of Ti 3 C 2 T x MXene nanosheets and Cu NPs. These components could get adsorbed onto the surface of the friction pairs and induce tribochemical reactions, resulting in the formation of Fe 2 O 3 and CuO. Consequently, a stable protective film composed of Fe 2 O 3 /CuO/Ti 3 C 2 T x MXene was formed on the worn surface, thereby reducing friction.

Fabric-based infrared stealth composite materials have both thermal insulation performance and low emissivity characteristics, and are suitable for fields such as infrared camouflage and thermal management. Therefore, this study innovatively designed a multi-layer structure fabric-based composite material that combines efficient infrared reflection and excellent heat insulation performance. Through the wet spinning and hot-pressing combined process, the functionalized MXene coating was combined with the SiO 2 aerogel microsphere (SiO 2 M)/gel fiber insulation layer, achieving a "surface low emissivity-internal high insulation" synergistic protection mechanism. A continuous and dense MXene low emissivity functional layer was constructed on the fabric surface. By adjusting the concentration of MXene, its emissivity in the 8–14 μm infrared wavelength range was reduced to 0.282, while maintaining excellent conductivity (surface resistance < 10 Ω/sq). The innovative design of the insulation system of SiO 2 M and gel fibers network was achieved. The aerogel microspheres effectively inhibit heat conduction through their nano-porous structure, while the gel fiber network hinders air convection. The combination of the two enhances the material's insulation performance (thermal conductivity = 0.04651 W/(m·K)). At a heating temperature of 70 °C, the thickness of the fabric is 1.263 mm, achieving a temperature difference effect of 11 °C. After adding SiO 2 M, the thermal insulation temperature difference increased by 5.8 °C. In sum, when heated to 70 °C, the radiation temperature only shows 43.4 °C, which means that the intensity of the infrared signal is significantly reduced. Therefore, this multi-layer structure fabric composite material provides some novel new ideas for related applications.

Consider that black phosphorene (BP) nanosheets can compensate each other between the MXene layers, thus preventing the agglomeration of MXene, and forming a more compact microstructure. This study successfully synthesizes f-MXene non-covalently modified by the strong electrolyte PHMB. A series of MXene/BP nanocomposite films are prepared by the strong electrostatic interaction between f-MXene and BP nanosheets and verified by FTIR, XRD, and XPS. The cross-section SEM imaging further reveals the formation of densely ordered aligned microstructures. Thanks to the compensation effect of BP nanosheets between f-Mxene layers, and constructed more efficient thermal conductivity pathways. With a low amount (5 wt%) of BP, the in-plane and through-plane thermal conductivity of 5-MXene/BP film increased to 12.71 and 0.37 W m-1 K-1, respectively. TGA and MCC results demonstrate the flexible 5-MXene/BP film exhibited an ultra-low total release rate (5.8 kJ g-1) and excellent thermal stability (66.74 wt% residual carbon). In consideration of their improvement in thermal conductive performance, MXene/BP nanocomposite film can be the most promising candidates for thermal management applications.

Memristors has been considered as a promising candidate for synaptic devices in next-generation neuromorphic computing. The two-dimensional MXene attracts considerable interest for use in memristor devices owing to its excellent physicochemical properties. However, MXene-based devices still suffer from unsteady conductive filaments and significant degradation. In this work, we present a highly-robust multilevel resistive switching memristor based Ti 3 C 2 T x by alkalization synthesis process and incorporate doped Ag nanoparticles into the active layer. This memristor exhibits a significant improvement in the uniformity of device parameters, including low threshold voltages, high switching ratio, high endurance, and long data retention compared to conventional memristors. The Ag nanoparticles embedded in oxidized Ti 3 C 2 T x renders a reduced variability in threshold voltages from 33 % to 8 %. Additionally, a remarkable accuracy (∼92.69 %) is achieved on the handwritten digits dataset by constructing an artificial neural network based on a memristor array. Overall, the proposed effective strategy could advance the performance of future manufactured MXene-based memristors.

Low-reflection electromagnetic interference (EMI) shielding materials have attracted increasing attention due to their capability to prevent secondary electromagnetic pollution, yet simultaneously achieving high EMI shielding effectiveness (SE) and low reflection remains a major challenge. In this study, heterostructure MXene@Ni hybrids were first synthesized, followed by the fabrication of a multilayered MXene@Ni/ANF film with an electro-magnetic dual-gradient structure via a layer-by-layer vacuum-assisted filtration process. The electro-magnetic dual-gradient structure was achieved by precisely controlling the MXene-to-Ni loading ratio and implementing a specific filtration sequence. The engineered gradient layered structure regulate the electromagnetic properties by modulating the mass ratio of MXene to Ni in each MXene@Ni/ANF layers. As a result, the composite film with precise control of the electro-magnetic gradient transition layers and reflection layer achieved excellent impedance matching and electromagnetic wave dissipation, ultimately resulting in remarkably efficient EMI shielding performance (37.6 dB) with low reflection characteristic (a low reflection coefficient of 0.72). This optimized structure ensures efficient electromagnetic wave absorption with minimal reflection, making it highly suitable for advanced EMI shielding applications.

The accumulation of uremic toxins, which ultimately leads to renal failure, results in systemic complications and necessitates efficient and biocompatible removal strategies. This paper presents the preparation of a biomimetic anisotropic aerogel composed of polyvinyl alcohol (PVA), sodium alginate (SA), and MXenes (Ti 3 C 2 T X ) via directional freezing. Inspired by plant vascular bundles, the resulting vertically aligned porous structure enhances the mechanical stability of and mass transfer in the material. The aerogel with its high MXene loading and high surface utilization offers remarkable adsorption capacities for urea (221.77 mg g −1 ) and creatinine (138.07 mg g −1 ). In vitro assays confirm the excellent hemo- and cytocompatibility of the aerogel. In a rabbit model of acute ischemic kidney injury, two-hour hemoperfusion with the aerogel significantly lowers the urea (38.67 to 16.17 mmol L −1 ) and creatinine levels (744.62 to 307.46 µmol L −1 ) without observable toxicity. The multidimensional biomimetic multipore anisotropic MXene aerogel presented here is a structurally optimized and biologically safe adsorbent for efficient uremic toxin clearance and a promising alternative to conventional hemodialysis.

Humanoid robots, except the sensing requirement of force and temperature, will get high risk of prolonged exposure to complex light conditions, especially the UV radiation in automotive baking workshop, outer space, et. al, which will make the circuits and electronic components extremely prone to aging, needing timely assessment as well. Here, a multimodal flexible tactile sensor is assembled by utilizing a novel melamine sponge-MXene@CsPbBr3 hybrid aerogel as the sensing unit, which the melamine sponge provides the deformable support skeleton, the MXene realizes the functions of piezoresistive pressure sensing and thermoelectric temperature detecting, and the CsPbBr3 realizes not only the light sensing behavior, especially the visual capacity of ultraviolet excited photoluminescence, but also the synergetic enhancement of thermoelectric ability. Via these different kinds of sensing mechanisms, the derived flexible tactile sensor realizes the multimodal response to pressure, temperature and ultraviolet without cross-coupling. Furthermore, via using a machine learning algorithm, it can distinguish hardness and material of six automotive parts with high recognition accuracy of 98.2 % and 98.6 %, respectively. Moreover, based on the visual photoluminescence capability, a sensory array is assembled to successfully recognize different shapes. These provides a feasible way to protect the robots when using in complex operating environments.

Pathogenic bacteria represent a considerable threat to public health and food safety, necessitating the development of advanced detection methodologies. In this study, a novel fluorescence sensing platform based on fluorescence resonance energy transfer (FRET) was established to detect Pathogenic bacteria with rapid response, exceptional sensitivity, and stable selectivity. Using carboxyl-modified Ti 3 C 2 T x MXene (Ti 3 C 2 T x -COOH) as nanocarriers, double-stranded DNA (dsDNA) were assembled to functionalize the MXene for rapidly efficient quenching of fluorescence dye-labeled aptamers and specific recognition of target bacteria. Upon the incorporation of target bacteria, the aptamer preferentially bound to bacteria, dissociating from the MXene and resulting in a significant and rapid increase in fluorescence intensity. Using E. coli O157:H7 and S. aureus as exemplar biotargets, the sensor demonstrated ultra-sensitive detection of E. coli O157:H7 and S. aureus with limits of detection (LOD, S/N = 3) as low as 0.61 CFU/mL and 1.62 CFU/mL, respectively, within a rapid response time of 15 min, thereby demonstrating superior performance in comparison to the majority of existing FRET-based biosensors. Moreover, this method demonstrates excellent reproducibility and stability, having been successfully applied to spiked milk samples. The recovery rates for S. aureus ranged from 90.2 % to 114.3 %, with acceptable RSDs of 1.4 % to 7.4 %, while those for E. coli O157:H7 ranged from 91.7 % to 93.6 %, with acceptable RSDs of 5.2 % to 8.7 %, confirming its strong potential for practical sample analysis. The present study establishes a foundational framework for subsequent research into biosensors for detecting targets and provides a new pathway for the analysis of other biological factors.

Copper ions (Cu2+), as a crucial trace element, play a vital role in living organisms. Thus, the detection of Cu2+ is of great significance for disease prevention and diagnosis. Nanochannel devices with an excellent nanoconfinement effect show great potential in recognizing and detecting Cu2+ ions. However, these devices often require complicated modification and treatment, which not only damages the membrane structure, but also induces nonspecific, low-sensitivity and non-repeatable detection. Herein, a 2D MXene–carboxymethyl chitosan (MXene/CMC) freestanding membrane with ordered lamellar channels was developed by a super-assembly strategy. The introduction of CMC provides abundant space charges, improving the nanoconfinement effect of the nanochannel. Importantly, the CMC can chelate with Cu2+ ions, endowing the MXene/CMC with the ability to detect Cu2+. The formation of CMC–Cu2+ complexes decreases the space charges, leading to a discernible variation in the current signal. Therefore, MXene/CMC can achieve highly sensitive and stable Cu2+ detection based on the characteristics of nanochannel composition. The linear response range for Cu2+ detection is 10−9 to 10−5 M with a low detection limit of 0.095 nM. Notably, MXene/CMC was successfully applied for Cu2+ detection in real water and fetal bovine serum samples. This work provides a simple, highly sensitive and stable detection platform based on the properties of the nanochannel composition.
