A seed self-sacrificial strategy was proposed to prepare Cu 2 O/MOF composites with tunable MOF lengths. • The synthesized MOF exhibited unique CO 2 adsorption capacity , with an optimal value of 97.50 cm 3 /g. • Tuning outer MOF length modulated CO 2 adsorption, enabling selective control over C 1 and C 2 conversion. • When the outer MOF layer reached 500 nm, Cu 2 O/MOF-2 achieved optimal C 2 selectivity with an FE of 81.43% and 16 h stability. • In situ FTIR and DFT showed that MOF-enhanced CO 2 adsorption raised *CO coverage on Cu 2 O/MOF, lowering C 2 formation barrier. In the electrocatalytic process of Carbon dioxide reduction reaction (CO 2 RR), one of the challenges faced by copper (Cu)-based MOF catalysts is insufficient structural stability, which leads to low utilization of active sites and reduced product selectivity. This study proposed a seed self-sacrifice strategy to fabricate Cu 2 O/MOF composite materials with tunable metal-organic framework (MOF) lengths, where cuprous oxide (Cu 2 O) serves as a metal-source seed to support the growth of the outer MOF. By regulating the length of the outer MOF material, the degree of CO 2 concentration can be modulated, thereby enabling precise control over the conversion rates of C 1 and C 2 products. In particular, when the length of the outer MOF is approximately 500 nm, Cu 2 O/MOF-2 achieves the highest selectivity for C₂ products, reaching 81.43%. In-situ Fourier-transform infrared spectroscopy measurements and density functional theory calculations reveal that the MOF with an appropriate length exhibits optimal adsorption effects for CO 2 . This increases the coverage of the *CO adsorption layer at the Cu 2 O/MOF interface, thereby lowering the energy barrier for C 2 products formation and accelerating the generation of ethylene and ethanol. This study pioneeringly establishes a novel pathway for selectively obtaining high-value energy products by controlling the component length.

The miniaturization of flexible wearable electronic devices and corresponding energy storage components is a prominent trend in current technological development. As a promising option for micro-energy storage, micro-supercapacitors (MSCs) could yield an outstanding solution for replacing traditional batteries if combined with triboelectric nanogenerators (TENGs) to build a self-powered energy storage microsystem integrating energy harvesting and storage. Herein, this work proposes to prepare N-doped hierarchical porous carbon nanomaterials using orange peel (low-cost biomass), which serve as microelectrodes for MSCs. Meanwhile, a flexible mask ink-spraying method is developed to enable the batch fabrication of multiple MSCs in parallel for improved reproducibility and efficiency. Notably, the synthesized N-doped biomass carbon features an ultrahigh specific surface area ( S BET , 2675.23 m 2 g −1 ), along with outstanding capacitive performance—achieving a specific capacitance of 529 F g −1 (1 A g −1 , aqueous electrolyte) and an excellent areal capacitance of 130 mF·cm −2 (3 mA·cm −2 , gel electrolyte). Additionally, a flexible TENG with voltage of 500 V and current of 304 μA is fabricated via 3D printing technology. The self-powered energy storage microsystem is further constructed by integrating the as-fabricated MSC with the 3D printed TENG. The biomass based MSC can be rapidly charged to 0.55 V within 70 s via 3D printed flexible TENG. This work not only promotes the practical application of MSCs in wearable electronics and self-powered sensor networks, but also offers a sustainable route for biomass waste valorization. In the future, self-powered energy storage microsystems can be integrated with flexible sensors and actuators, showing broad application prospects in the Internet of Things, portable medical devices, and distributed intelligent systems.

Arenes possess high energy density and outstanding combustion performance, making them key components of aviation fuels. However, the conversion of lignin-derived phenolic compounds to arenes typically requires high temperatures (above 300°C), which not only alters the catalyst structure and promotes side reactions but also increases energy consumption and potential safety risks. In this study, a green and environmentally friendly two-step method for the low-temperature conversion of phenol to benzene was proposed, achieving controllable product selectivity at low temperatures. The hydrogenation of phenol occurred efficiently at room temperature and achieved 100% conversion of cyclohexanol. Then, the dehydration and dehydrogenation of cyclohexanol was performed at a low temperature of 200°C, resulting in 90.1% selectivity of benzene. In addition, the catalyst showed good cycling stability, with the benzene selectivity remaining at 84.6% after four reaction cycles. Based on the effect of reaction time on product distribution, a proposed reaction pathway for cyclohexanol to benzene was discussed. Moreover, the comparison between this two-step method and previously reported one-step methods for phenol to benzene was carried out, highlighting the superiority of this work. Graphical This work proposed a two-step process for the conversion of lignin-derived phenol to produce benzene at low reaction temperatures of 200°C, resulting in 100% conversion and 90.1% benzene selectivity.

Nanozyme-infused sponge hydrogels suppress swelling and enable intrinsic antibacterial activity. • Coupling vertical compression/lateral expansion allows simultaneous normal/shear stress detection. • A 2 × 2 electrode array generates unique signal patterns to identify sliding directions and motion trends. • Quantifies 20–1000 g objects and enables grip-force regulation via polynomial regression modeling. • A 4-channel tactile coding strategy converts characters into real-time electrical signals. Underwater wearable sensors are highly desirable for aquatic operations, soft robotics, and human-machine interaction. However, their practical deployment remains limited by hydrogel swelling, hydrostatic-pressure disturbance, biofouling, and insufficient multidirectional tactile feedback. Here, we report a nanozyme-enabled antibacterial sponge hydrogel-based electronic skin for underwater tactile sensing and slip-direction recognition. The electronic skin is fabricated by physically confining a prepolymerized chitosan/polyacrylamide/nanozyme precursor within a commercial open-cell poly(vinyl alcohol) (PVA) sponge, followed by repeated in situ UV polymerization to form a composite denoted as CS/PAM/CCN/PVA. The incorporated C 3 N 4 @CDs-ZIF nanozyme provides conductivity, fluorescence, and antibacterial activity, while the porous PVA scaffold mechanically supports the hydrogel network and effectively suppresses excessive re-swelling in water. Owing to the coupling between vertical compression and lateral expansion, the resulting three-dimensional (3D) sensors can simultaneously detect normal pressure and direction-dependent shear deformation. A 2 × 2 electrode array generates characteristic multidimensional signal patterns, enabling identification of sliding direction and recognition of relative motion trends. As a wearable fingertip device, the sensor supports underwater grasping experiments for objects with masses ranging from 20 to 1000 g and allows estimation of the minimum force required to avoid slippage through resistance-threshold analysis. In addition, a second-order polynomial empirical fit is established to describe the relationship among grasping pressure, object mass, and resistance change. A four-channel tactile coding strategy further enables rapid underwater message transmission by converting characters into real-time electrical signals. This work provides a multifunctional electronic-skin platform for tactile perception, grasp-force regulation, and low-infrastructure communication in freshwater environments.

Accurate environmental detection fundamentally depends on reliable calibration. Although AI-assisted curve fitting improves analytical efficiency, it often relies on empirical, concentration-dependent correction coefficients that can introduce deviations from true values and compromise accuracy. Thus, instead of over-relying on AI-driven fitting, rigorous mechanistic understanding of sensing processes and deviation sources is essential to ensure reliable detection. Herein, we constructed a self-calibrating sensing system by functionalizing solid-state nanochannels with rationally designed super-sandwich (SSW) DNA probes, enabling reliable sensing and providing clear insight into the mechanisms underlying signal deviations. By integrating complementary fluorescence and ionic current readouts derived from the same molecular recognition event between the SSW-DNA probe and the target, the negative deviation of the fluorescence signal (exceeding −20.0%) and the positive deviation of the electrical signal (exceeding +20.0%) can effectively offset each other. These deviations, originating from incomplete SSW-DNA disassembly, were reduced to below ± 5.0% through this cancellation mechanism. This work not only significantly improves sensing reliability but also clarifies the underlying deviation mechanisms of nanochannel-based sensors, offering valuable insights for environmental, food, and biomedical applications.

A Fe/V-CN nanozyme with synergistically enhanced POD-like activity was rationally designed. • A sensitive cascade colorimetric platform for detecting gastric cancer-related D-amino acids was successfully constructed. • The assay supports reliable quantification of D-amino acids in complex human saliva matrices. The development of a practical and reliable cascade colorimetric method for detecting D-amino acids (DAAs) provides a promising tool for the prevention and preliminary diagnosis of gastric cancer. Herein, a bimetallic Fe V supported on graphitic carbon nitride (Fe/V-CN) nanozyme was rationally designed and synthesized via a simple annealing strategy. The atomic dispersion of Fe and V species, along with their coexisting multivalent states (Fe 2+ / 3+ , V 4+ / 5+ ) synergistically boosted the intrinsic peroxidase-like (POD) activity to Fe/V-CN, which were characterized by a high substrate affinity ( K m of 0.078 and 0.083 mM for TMB and H 2 O 2 ) and an accelerated catalytic turnover ( V max of 4.94 × 10 −7 and 7.76 × 10 −7 M·s −1 , respectively). Leveraging this improved activity, a cascade colorimetric sensing system was developed by integrating Fe/V-CN with D-amino acid oxidase (DAAO) for the specific detection of DAAs. The platform exhibited favorable analytical performance for D-proline (D-Pro) and D-alanine (D-Ala), offering wide linear ranges of 0–200 μM and 0–160 μM and low detection limits of 0.93 μM and 1.45 μM, respectively, combined with acceptable selectivity against common interferents. For real-sample analysis, the platform was successfully implemented in determine DAAs in human saliva, delivering satisfactory recoveries (95.8–105.7%) and good precision (RSD < 3.5%). This work presented a synergistic Fe/V bimetallic nanozyme and a practical sensing strategy, demonstrating the feasibility of DAAs detection in complex biological matrices.

The phosphatase-like activity of UiO-66 was improved by introducing OMS. • UiO-66-OMS exhibited twice the catalytic activity of pristine UiO-66. • This enhanced activity results from enlarged pores and boosted Lewis acidity. • A sensitive colorimetric immunoassay was developed for the detection of CEA. UiO-66 with open metal sites (UiO-66-OMS) nanozymes were synthesized via defect engineering through the introduction of benzoic acid as a modulator during UiO-66 synthesis. As a monocarboxylic acid analogous to the organic ligand 1,4-benzenedicarboxylic acid (BDC), benzoic acid competes with BDC for coordination to Zr O clusters, thereby creating abundant coordinatively unsaturated open metal sites while preserving the crystal structure of UiO-66. Using 4-nitrophenyl phosphate ( p -NPP) as the model colorimetric substrate, UiO-66-OMS exhibited enhanced phosphatase-like catalytic activity, which was twice that of pristine UiO-66. Mechanistic investigations revealed that the increased activity stems from the enlarged pore size and specific surface area of the nanozyme, as well as its enhanced Lewis acidity. By employing UiO-66-OMS as an antibody label, a sensitive colorimetric immunoassay was developed for the detection of carcinoembryonic antigen (CEA), with a linear range of 10–400 ng/mL and a limit of detection of 1.17 ng/mL.

Zwitterionic hydrogels are attractive physical barriers for preventing postoperative abdominal adhesions because of their outstanding antifouling properties; however, their inherent biological inertness and poor degradability often hinder therapeutic efficacy and clinical translational potential. Herein, we report a bioactive and dissociable zwitterionic nanocomposite hydrogel that integrates zwitterionic polymer chains with clearance potential, hydrolytically dissociable networks, and Prussian blue (PB) nanozymes. A molecular-weight-controlled polycarboxybetaine acrylate precursor (PCBOAA, ∼50 kDa) was prepared by reversible addition–fragmentation chain-transfer (RAFT) polymerization and subsequently crosslinked with dithiothreitol via thiol-acrylate Michael addition reaction to form a zwitterionic hydrogel featuring β-thioether ester linkage, which could gradually dissociate under physiological conditions into low-molecular-weight polymer with reduced risk of prolonged retention. Incorporation of PB nanoparticles further endowed the PCBOAA@PB hydrogel with antioxidative and immunomodulatory activity. In vitro , PCBOAA@PB hydrogel could effectively resist protein adsorption and cell adhesion and suppress pro-inflammatory macrophage polarization. In a rat cecum–abdominal wall adhesion model, it exhibited markedly superior anti-adhesion efficacy compared with a clinically used hyaluronic acid hydrogel. Mechanistically, this excellent anti-adhesion efficacy of PCBOAA@PB hydrogel as a physical barrier stemmed from its dual ability to reprogram the postoperative inflammatory–fibrotic microenvironment and reduce excessive collagen deposition. In summary, this work provides a zwitterionic hydrogel design strategy that integrates antifouling, microenvironment modulation, and clearance potential for effective adhesion prevention.

Cystine-functionalized MXene (MC)/poly(ether-benzimidazole) (OPBI) composite membranes were developed for high-temperature proton exchange membrane fuel cells (HT-PEMFCs). The functionalization was confirmed by XPS and FTIR. The optimal OPBI/MC-15 membrane exhibited an acid doping level of 27.8 and proton conductivity of 163.7 mS cm −1 at 180 °C under anhydrous conditions, which was 2.8-fold higher than that of pristine OPBI. The disulfide (S–S) moieties served as effective radical scavengers, enabling exceptional oxidative stability for the composite membranes. Specifically, sample OPBI/MC-15 retained approximately 95% of its initial mass after 200 h in Fenton's reagent at 80 °C, representing a dramatic improvement over pristine OPBI. Single-cell tests delivered peak power densities of 592 and 887 mW cm −2 at 140 and 160 °C, respectively, with open-circuit voltages exceeding 0.97 V. This work demonstrates a synergistic strategy combining enhanced proton transport and oxidative stability for advanced HT-PEM applications.

The Pt/γ-AlOOH-IP was prepared using γ-AlOOH support by impregnation method. • The strong MSI and electron-rich Pt sites are fabricated in Pt/γ-AlOOH-IP. • Pt/γ-AlOOH-IP exhibits excellent catalytic performance in the hydrosilylation. • Electron-rich Pt sites promote the TES adsorption and Si–H bond cleavage. Hydrosilylation is a highly important method for the preparation of organosilicon compounds, in which homogeneous Pt catalysts exist poor recyclability and high production costs. Here, we prepared supported Pt-based catalyst (Pt/γ-AlOOH-IP) using γ-AlOOH support by impregnation (IP) method, in which strong metal-support interactions (MSI) and electron-rich Pt sites were fabricated. Catalytic measurements show that Pt/γ-AlOOH-IP has the best catalytic activity in the conversion of 1-octene and triethoxysilane (TES)via hydrosilylation to n-octyltriethoxysilane (OTES), the yield of OTES is 93.6% with 94.3% selectivity at 80 ℃, 2.5 h, m (Pt) /m (1-octene) = 7.5 × 10 −5 and n (TES) /n (1-octene) = 1.33, which are commensurate with homogeneous Karstedt’s catalyst. The significant catalytic performance of Pt/γ-AlOOH-IP originates from more electron transfer between Pt and γ-AlOOH. Electron-rich Pt sites promote TES chemisorption and Si–H bond dissociation, and improve catalytic activity, which are corroborated by the DFT calculations. This finding enhances the insight of MSI and offers an easy method to prepare efficient heterogeneous catalysts for industrial hydrosilylation reactions.

Neoantigen peptides evade central thymic tolerance due to their absence in normal tissues, making neoantigen vaccines a leading strategy for personalized cancer immunotherapy. Although nanoparticle-based delivery systems are widely used to enhance neoantigen immunogenicity, traditional nanovaccines often incorporate multiple adjuvants and inert carriers, which could hinder efficient antigen delivery and raise biosafety concerns. Herein, we report a carrier-free neoantigen nanovaccine (CpG-2′F/Neo WD ), assembled via fluorination-induced self-assembly for hepatocellular carcinoma (HCC) immunotherapy. This nanovaccine is formed by the co-assembly of fluorinated CpG (CpG-2′F) with the HCC neoantigen peptide (Neo WD ), yielding nanoparticles of approximately 69 nm with a high Neo WD loading efficiency of 67.18 wt%. In vitro studies demonstrate that the nanovaccine potently facilitates dendritic cell uptake and promotes endosomal/lysosomal escape, enhancing antigen cross-presentation efficiency by 2.05-fold compared to the antigen group. In vivo , by efficiently targeting lymph nodes (LNs), the nanovaccine orchestrated both innate and adaptive immune responses against cancer cells, leading to the pronounced expansion of antigen-specific CD8 + T cells and memory T cells. In both prophylactic and therapeutic Hepa1–6 HCC models, this nanovaccine effectively suppressed the progression of poorly immunogenic HCC. Therefore, this study presents a facile, safe and potently immunogenic carrier-free nanovaccine platform for HCC immunotherapy.

Efficient biphasic nanostructures enable interlocking friction in shear thickening fluids. • Surface-engineered ZnO–SiO 2 hybrids achieve 192% viscosity enhancement under shear. • Kevlar/STFs/PU composites exhibit 284% higher impact resistance via interface design. • Provides a meaningful application scenario for smart, lightweight protection under dynamic loading. Shear thickening fluids (STFs) hold significant promise for advanced impact-resistant applications; however, their performance is fundamentally constrained by limited particle–particle interactions within conventional colloidal systems. Herein, we propose an efficient materials design strategy based on surface-engineered biphasic nanocomposites, which synergistically integrate anisotropic ZnO nanorods with isotropic spherical nanoparticles to construct an interlocking frictional network. This engineered hybrid architecture enhances stress-induced particle coupling by promoting directional interfacial friction and geometric confinement, thereby fundamentally modulating the shear thickening mechanism. Rheological analyses reveal that the STFs formulated with these composite nanoparticles (CNP-based STFs) exhibit a remarkable 192% enhancement in maximum viscosity compared to conventional silica-based STFs. This is attributed to the emergence of a geometrically confined domain effect, wherein anisotropic–isotropic particle interlocking facilitates efficient stress transfer and energy dissipation under dynamic shear. Furthermore, when integrated into Kevlar/polyurethane (PU) composite fabrics, the CNP-based STFs deliver a significant 284% improvement in impact resistance relative to pristine Kevlar, and a 43% enhancement compared to Kevlar/PU composites without STFs infusion. This study not only elucidates the critical role of surface roughness, interfacial adhesion, and particle anisotropy in governing shear thickening behavior but also demonstrates a robust and scalable strategy for designing high-performance STFs. The insights gained herein open new avenues for the development of next-generation adaptive, high-efficiency protective materials for applications in personal armor, aerospace, and soft robotics.
