African Swine Fever (ASF) poses a severe threat to the global pig husbandry. In the absence of an effective vaccine, developing rapid and accurate diagnostic methods is crucial for epidemic control. This study designed a low-cost microfluidic chip and integrated nucleic acid rapid detection device (INARDD) based on colorimetric principles combined with magnetic bead based nucleic acid extraction technology. Manufactured using micro computer numerical control machine tools (CNC) and 3D printing, the device fully automates the entire process include nucleic acid extraction, transfer, loop-mediated isothermal amplification (LAMP), and detection without requiring external equipment or manual intervention. Experimental results demonstrate high sensitivity (94.1 %, 32/34), specificity (97.7 %, 42/43), and accuracy (96.1 %, 74/77), with a detection limit of 10² copies/μL. The device features low production costs (approximately $69.1), low per-test expenses, and a portable design (2 kg), facilitating field deployment. This study provides an economical and efficient solution for rapid on-site diagnosis of African swine fever, holding significant implications for enhancing epidemic control and ensuring meat safety. It also offers technical reference for developing portable diagnostic systems for other infectious diseases.

Sluggish water dissociation kinetics in the alkaline hydrogen evolution reaction (HER) continue to hamper its practical production. Herein, a class of heterojunction electrocatalyst featuring Ru-Ni(OH) 2 interfaces on nickel foam (NF) with self-engineered built-in electric fields (BIEF) has been synthesized via a simple in situ galvanic replacement reaction. The as-made hierarchical architecture of Ru-Ni (OH) 2 /NF exhibits a record overpotential of 9.6 mV at a current density of 10 mA cm −2 for alkaline HER, surpassing most reported catalysts and the commercial Pt/C benchmark. Furthermore, it also reveals exceptional catalytic activity towards hydrazine oxidation reaction (HzOR) at 100 mA cm −2 with a remarkably low potential of ca. 0.015 V vs. RHE (reversible hydrogen electrode). The assembled overall hydrazine splitting (OHzS) system integrating HER and HzOR requires a cell voltage of about 0.09 V to reach 50 mA cm −2 , which is 1.637 V lower than the corresponding overall water splitting (OWS) device. Systematic analysis and calculation reveal that the BIEF induces the redistribution of interfacial electrons for Ru, facilitating H 2 O dissociation and intermediates conversion to deliver the ultra-high electrocatalytic performance. This work provides an avenue for the design and preparation of electric field-mediated catalysts towards sustainable energy conversion.

Flexible microsupercapacitors are attracting much more attention for use in miniature energy storage devices due to their attractive electrochemical characteristics. However, it is difficult to achieve high energy density and long-term stability at the same time due to a lack of suitable high-specific-energy materials. Herein, an innovative asymmetric microsupercapacitor is obtained by the highly efficient surface chemistry regulation of conductive two-dimensional nanosheets of both graphene and MXene with highly active covalent groups. To optimize the positive graphene material, graphene oxide powder is first employed, undergoing a fast expansion and exfoliation process via water molecule explosive vaporization. Then, the conductive graphene sheet layer with a high specific surface area is oxidized selectively by acid treatment to introduce pseudocapacitive groups at an optimized proportion and density (more –COOH and less –OH), and this is labelled as expanded-and-oxidized graphene (EOG). To optimize the negative MXene material, delaminated MXene nanosheets undergo hydroxyl substitution through alkalization, and the two-dimensional (2D) lamellae become wrinkled using coulombic attraction for fast intercalation pseudocapacitance, and this is labelled as wrinkled-and-hydroxylated MXene (WOM). Through surface chemistry modification and all-pseudocapacitive 2D structure design, flexible EOG and WOM composite electrodes exhibit capacities of 382 F g−1 and 550 F g−1, respectively, and have remarkable stability. An assembled proton-type solid-state microsupercapacitor with a voltage window of 1.5 V readily achieves an energy density of 47.25 mW h cm−3 (23.62 W h kg−1) at a power density of 1900.55 mW cm−3 (950.27 W kg−1), with high capacity retention of 86.8% after 8000 cycles. This work shows a well-designed microdevice with flexible and integrable properties based on 2D microstructure engineering for use in flexible electronics.

Uranium (U) contamination in natural waters poses a serious threat to both ecosystems and human health. However, the efficient adsorption and separation of U(VI) remains significantly challenging due to its extremely low concentrations and the complexity of coexisting ions. Herein, we demonstrated that MgAl-LDH/CNT composites with synergistic interfacial properties were successfully synthesized via a hydrothermal method, enabling efficient adsorption and separation of U(VI) from various natural waters while maintaining excellent chemical stability and anti-interference capacity. The evaluation of adsorption performance indicated that U(VI) adsorption by MgAl-LDH/CNT composites reached equilibrium within 10 min at pH 3, exhibiting a maximum adsorption capacity of 126.4 mg/g at 298 K. Furthermore, MgAl-LDH/CNT composites exhibited excellent resistance to coexisting ions, maintaining the adsorption efficiency over 95 % after five adsorption-desorption cycles. The adsorption mechanism studies based on FT-IR, XPS, and DFT revealed that the -OH function groups in MgAl-LDH/CNT composites were involved in U(VI) complexation with a binding energy of 3.69 eV. U(VI) was preferentially enriched on the MgAl-LDH surface and its interface with CNT, confirming the interface-dominated adsorption mechanism of MgAl-LDH/CNT composites. This work provides a promising strategy for efficient adsorption and separation of U(VI) from natural waters, while offering valuable insights into environmental remediation and sustainable nuclear resource management.

A cost-effective and robust electrocatalyst that can operate at industrial-scale current densities is critical for producing green hydrogen through water splitting. We present a 2D RuCoFeO x nanosheet structure, serving as an electrocatalyst for both water splitting and anion-exchange membrane water electrolyzer (AEMWEs) study. The composite material demonstrates outstanding electrochemical performance with acceleration in OER kinetics, enhancement in active surface area, reduced overpotentials, and excellent stability. Based multiple synchrotron radiation techniques and in-situ spectroscopes, we have revealed the electron coupling between Co/Fe and Ru through oxygen-bridge bonding and multi-site cooperative effect. The advanced mapping of resonant Auger spectroscopy (mRAS) effectively differentiates distinct orbital hybridization states, thereby confirming charge transfer between sites. In-situ attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) and indicates that loaded Ru serve as additional adsorption sites, modulating adsorption of *OOH intermediates. In AEMWEs, the RuCoFeO x showcases high activity, achieving 1 A cm −2 at 1.76 V, and maintains stability at 1 A cm −2 beyond 700 h. Our investigation offers an insight into the principles of multisite cooperative catalysis and propels the design of highly efficient electrocatalysts for water splitting.

Polytetrafluoroethylene (PTFE) has become an important engineering polymer due to its unparalleled chemical inertness and wide operating temperature range. In this study, complex, intricate, and high-performance PTFE components were prepared using Vat Photopolymerization (VPP) technology, and their composition design and microstructural evolution were investigated. Additionally, the effects of heat treatment processes and cooling rates on mechanical properties were further analyzed. When the sintering temperature was 410 °C, the holding time was 90 min, and the cooling rate was 3 °C/min, the density of PTFE reached 99.8 % of traditionally processed PTFE parts, while achieving excellent mechanical properties, with a tensile strength of 25.3 ± 0.2 MPa and an elongation at break of 224± 5 %. Furthermore, the tensile strengths at −150 °C and + 150 °C were 49.2 ± 4.3 MPa and 5.9 ± 3.0 MPa. Subsequently, the mechanical properties of TPMS with different structures and porosities were investigated under high and low temperatures. At room temperature, the compressive strength at 10 % deformation ranged from 1.2 to 4.3 MPa for different minimum surface areas. Under low-temperature conditions (−150 °C, −80 °C), the stiffness and strength of the PTFE structure significantly increased, with compressive strength at 10 % strain ranging from 5.3 to 15.4MPa, indicating a shift in the failure mechanism due to increased material brittleness. Conversely, high temperatures (+200 °C, +150 °C) cause PTFE to soften significantly, with compressive strength ranging from 0.4 to 1.1MPa at 10 % strain, and a substantial decrease in stiffness and strength, reflecting highly plastic deformation behavior.

To address the critical impact of temperature fluctuations on precision, stability, and friction coefficients (COF) in fluid machinery (e.g., pumps, compressors, motors), a carbon dots-embedded photoluminescent composite coating (CDs@PEEK) is developed for simultaneous non-contact temperature sensing and enhanced tribological performance on equipment surfaces. The CDs@PEEK coating exhibits temperature-responsive fluorescence, characterized by a linear intensity decrease from 50 to 120 °C with a sensitivity of 0.769 % °C −1 and excellent reproducibility of 98.01 % over five cycles. Additionally, it demonstrates superior tribological performance, achieving a lower COF (0.169 ± 0.004) compared to PEEK (0.178 ± 0.008) and stainless steel (0.335 ± 0.005), along with a reduced wear rate of 0.00548 ± 0.00010 mm 2 –4.0 % lower than PEEK and 64.6 % lower than stainless steel—indicating significantly enhanced wear resistance. The coating keeps stable fluorescence and temperature sensing after repeated heating, rubbing, and boiling. CDs@PEEK serves as a multifunctional coating for wear resistance and visual temperature monitoring, promising for smart fluid machinery.

In this work, the functionalization of mesoporous carbon@silica nanoparticles was described for recognizing monocrotaline in vivo to reach the goal of develop a diagnostic framework for hepatic veno-occlusive disease (HVOD) that aligns with biochemical indicators. Initially, adenine was successfully immobilized on hollow mesoporous carbon using 3-aminopropyltriethoxysilane as a coupling agent. The structural and morphological properties of the adenine-coated carbon nanoparticles were systematically characterized using a combination of analytical techniques, including Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). The adsorption performance of the adenine-coated nanoparticles was thoroughly evaluated through adsorption isotherm and kinetics studies. Subsequently, nanoparticles were employed as solid-phase extraction adsorbents for the enrichment of potential hepatotoxic compounds in rat liver tissues. The concentrations of monocrotaline were meticulously correlated with pharmacological indices and biochemical indicators in a rat model, which provided novel insights into the diagnosis of HVOD.

The high nickel stoichiometry in Li[Ni 0.8 Co 0.1 Mn 0.1 ]O 2 (NCM811) cathode materials, while advantageous for specific capacity enhancement, introduces concomitant challenges including (i) surface instability due to high surface residual Li compounds (RLCs) content, and (ii) accelerated structural degradation and deleterious phase transitions during electrochemical cycling. To address these challenges, NCM811 was treated with an aqueous solution of ammonium niobium oxalate, which not only reduced the RLCs content on the surface, but also in-situ constructed a LiNbO 3 coating layer on the surface of the NCM811 materials after the re-calcination process. Within a potential range of 2.75–4.3 V at 0.5C and 25 °C, the Nb-modified NCM811 materials exhibit the advantages of improved specific capacity of 215.3 mAh g −1 and excellent capacity retention of 92.3 % after 200 cycles. This integrated approach synergistically combines wet coating with re-calcination treatment to achieve dual modification of NCM811 cathodes-simultaneously reducing RLCs while enabling in-situ construction of a lattice-doped LiNbO 3 coating layer, demonstrating exceptional potential for scalable industrial implementation through its combined performance enhancement and process compatibility.

Fe-based oxygen carriers (OCs) exhibit significant potential for biomass chemical looping gasification (BCLG) to produce hydrogen. However, variations in OC composition and operating conditions strongly affect BCLG performance. In this study, Fe-based OCs were optimized by integrating experimental results with machine learning (ML) techniques, considering both material composition and operational parameters. Experimental evaluation identified Fe 8 Al 2 as the most effective OC, achieving a hydrogen yield of 22.83 mmol/g biomass. These experimental data were combined with literature datasets to train an XGBoost model, yielding a robust predictive performance (R 2 > 0.824). Interpretable ML analyses using Shapley Additive Explanations (SHAP) and partial dependence plots (PDP) revealed that the steam-to-biomass ratio and Fe content were the most influential factors for hydrogen production. This integrated approach demonstrates a viable pathway for OC optimization by supplementing limited datasets with targeted experimental data, thereby advancing hydrogen production from BCLG.

SiOC ceramics were fabricated via the 1000 °C pyrolysis of cured green bodies derived from a ceramic precursor slurry system. The effects of the carbon nanotube (CNT) content on both the Si-O-C polymer precursor slurry and its resulting ceramic products were investigated. This study focused on slurry preparation, green-body properties, pyrolysis conditions, ceramic microstructure, and final performance of the resulting ceramics. The preparation method and properties of the CNTs/Si-O-C precursor materials were also examined. The experimental results demonstrated that at the optimal CNT loading of 1.5 wt%, the charge-transfer resistance of the resulting SiOC ceramic was 4.08 × 10 4 Ω cm 2 .

Temperature fluctuations during cold chain transportation of Chinese cherry serve as a critical stress factor. This study systematically elucidated both the immediate and persistent physiological effects of temperature fluctuations on Chinese cherry quality. Compared with constant storage at 5 °C, three consecutive temperature fluctuations between 5 and 10 °C induced progressive and significant changes in fruit phenotypic traits. At the end of temperature fluctuations (Day 4), Chinese cherry showed 135.22 % higher ΔE and 9.02 % lower firmness versus 5 °C isothermal controls. Post-storage damage reached 78–93 % of that under constant 10 °C conditions. The observed effects primarily stem from temperature fluctuations triggering rapid accumulation of malondialdehyde, a key cell membrane oxidation byproduct, along with elevated ATP levels, which in turn enhance the activities of polyphenol oxidase and peroxidase to promote anthocyanin synthesis and phenolic oxidation, thereby inducing color transformation. Additionally, the specific upregulation of pectin metabolism-related genes ( cCPG1-3 and cCPME3-4 ) enhanced polygalacturonase and pectin methylesterase activities, accelerating pectin demethylesterification and driving nanoscale structural transitions in pectin polymers. The study comprehensively demonstrated the immediate and persistent effects of temperature fluctuations on color transformation and softening-related quality deterioration in Chinese cherry fruits, providing a scientific foundation for developing precision cold-chain logistics strategies.
