Self-healing anticorrosive coatings are essential for extending the lifespan of metallic materials in aggressive environments. This study presents a novel sandwich-structured coating composed of a polydopamine (PDA) inner layer, a ZIF-67 electroplated interlayer, and MXene/CNTs fillers incorporated into a waterborne acrylic epoxy (EA) matrix. The PDA layer enhances adhesion, while the ZIF-67 interlayer functions as an active inhibitor reservoir that responds to pH changes, releasing Co 2+ and 2-methylimidazole to promote defect repassivation and self-healing. The outer MXene/CNTs layer significantly improves barrier properties by forming a tortuous path for corrosive agents and enhancing interfacial stability. Compared with single-component coatings, the sandwich-structured composite coating exhibited markedly enhanced corrosion resistance in harsh acidic environment, with an obvious increase in corrosion potential. Moreover, a high R ct value of 1.79 × 10 5 Ω cm 2 was maintained by this coating even after 30 days of service, evidencing its durable protection. Under scratched conditions, the coating exhibits efficient self-healing, recovering its impedance and repassivating defects. This work demonstrates the synergistic benefits of the PDA/ZIF-67/MXene system, offering an effective solution for long-term corrosion protection with self-healing properties, suitable for various engineering applications.

Polyaniline (PANI) is regarded as a prospective sensing material for room-temperature NH 3 detection owing to its high sensitivity and selectivity. In this study, WO 3 nanoflowers were prepared via a simple chemical bath deposition method, and PANI/WO 3 heterojunctions were subsequently fabricated through an in situ polymerization process. To evaluate the contribution of the heterojunction to gas-sensing performance, four sensors with different composite ratios were constructed. Among them, the optimized PW1-2 sensor exhibits a response of 3.8–100 ppm NH 3 at room temperature, which is 1.6 times higher than that of pure PANI. Notably, it achieves an ultrafast response time of only 26 s, representing an 8.8-fold improvement over pure PANI (230 s), along with near-complete desorption capability. Furthermore, PW1-2 demonstrates excellent humidity resistance, with stable responses ranging from 3.7 to 3.97 under 40–80% relative humidity. Comprehensive characterization by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy TEM, x-ray photoelectron spectroscopy (XPS), Raman spectroscopy, thermogravimetric analysis (TGA), and Brunauer–Emmett–Teller (BET) analysis reveals that PANI nanofibers uniformly wrap around WO 3 nanoflowers, forming p–n heterojunctions at the interface. XPS analysis shows that PW1-2 possesses the highest protonation degree (51.88%), which correlates with its superior sensing performance. Unlike conventional PANI/WO 3 composites, the enhanced performance is not primarily attributed to specific surface area or porosity but rather to the synergistic effect of morphological characteristics and heterojunction formation. Compared with previously reported PANI/WO 3 sensors, our PW1-2 sensor offers significantly faster response, better humidity tolerance, and complete desorption. This work provides a promising strategy for designing high-performance, humidity-resistant room-temperature NH 3 sensors. Graphical

This research engineers a high-performance superhydrophobic composite system by synergizing an Al arc-sprayed bond coat with a nanostructured CeO 2 topcoat deposited via solution precursor plasma spraying (SPPS). The objective was to utilize the intrinsic micro-roughness of the arc-sprayed layer to stabilize a Cassie–Baxter wetting state without organic modifiers. Optimization of the SPPS process identified the critical parameters for achieving a hierarchical topography: a standoff distance of 7 cm, a liquid feed rate of 42 rpm, a transverse speed of 500 mm/s, and a total of 4 spray passes. This optimized protocol leveraged the “shadowing effect” of the Al bond coat (Ra ~ 13µm), resulting in a 90% reduction in the required spray passes compared to conventional coatings on smooth substrates. Microstructural analysis confirmed the formation of a phase-pure CeO 2 topcoat with a refined crystallite size of 81 nm. The resulting hierarchical architecture yielded a water contact angle of 151° and a contact angle hysteresis of 2°. Mathematical modeling via the Cassie–Baxter equation quantified a liquid–solid contact area fraction of 0.04, indicating that 96% of the droplet base was supported by trapped air pockets. Electrochemical performance evaluated via potentiodynamic polarization and electrochemical impedance spectroscopy after 96 hours of immersion in 3.5 wt.% NaCl demonstrated superior durability. The Al-CeO 2 composite exhibited a 128% increase in corrosion resistance and a 50.5% reduction in the corrosion rate compared to the bare Al bond coat. While the single-layer benchmark system experienced a 95.5% reduction in coating resistance due to electrolyte infiltration, the optimized Al-composite restricted degradation to 40%. Surface chemistry analysis via x-ray photoelectron spectroscopy revealed that the transition to superhydrophobicity is governed by the spontaneous adsorption of airborne volatile organic compounds, ensuring chemical stability up to 450°C. These results establish a robust, industrially scalable manufacturing route for protective coatings in aggressive marine environments.

Chloride ions in zinc smelting accelerate electrode deterioration and corrosion of equipment, reducing the quality of zinc products. Conventional dechlorination technologies for copper slag pose significant challenges, including inefficient mass transfer due to solid-film barriers, limited reactivity due to the low activity of copper slag, and prolonged processing times. This paper proposes an ultrasonic-enhanced reduction deep-dechlorination technology based on rapid chemical reactions, establishing a liquid-phase mass transfer to completely break through the solid film barrier. The optimized parameters obtained for this technology are initial reaction solution pH 3.6, Cu 2+ :Cl⁻:H 2 A molar ratio = 1.5:1:0.75 reaction temperature is 20℃ (room temperature), ultrasonic power density of 26.7 W/L, reaction time of 3 min, achieving a 96.5% reduction in chloride ions, and fast decreasing from 1 g/L to 0.0353 g/L. As revealed by thermodynamic calculations, compared with the current dechlorination process for copper slag, this method improves reaction kinetics by 18.6%, reduces the thermodynamic potential by 59.3%, and increases the equilibrium constant by a factor of 6.7 × 10 9 . Dynamics calculations show that the calculated energy threshold (E a ) of the reaction in the ultrasound addition experiment is 37.82 kJ/mol. Ultrasound incorporation reduces the activation energy by 24.6%, accelerating the reaction and improving dechlorination efficiency.

Metabolic hijacking of tryptophan (Trp) via the IL4I1-AHR axis is a pivotal immune evasion mechanism in cancers, yet therapeutic strategies to disrupt this pathway remain unexplored. Here, we report the identification of ZY-MY-111, a selective small-molecule inhibitor of interleukin-4-induced-1 (IL4I1), through an in-house compound library screening and structural optimization. ZY-MY-111 exhibits potency (IC 50 = 1.86 ± 0.13 μM) in blocking IL4I1-mediated oxidative deamination. Mechanistically, ZY-MY-111 acts as a mixed-type inhibitor, competitively occupying the catalytic pocket of IL4I1 and disrupting Trp-AHR signaling in cells. Functionally, ZY-MY-111 promotes T cell proliferation, enhancing immune responses against the tumor cells. In syngeneic tumor models, ZY-MY-111 achieved 49% tumor growth inhibition in CT26 colon carcinoma ( P < 0.001) and 56% tumor growth inhibition in A20 lymphoma ( P < 0.001) by remodeling the immunosuppressive microenvironment: increasing CD8 + /CD4 + T cell ratios, reducing myeloid-derived suppressor cells (MDSCs, 59% decrease), and enhancing effector memory T cell infiltration. Our findings position IL4I1 inhibition as a potential strategy to restore anti-tumor immunity.

Heavy metal contamination in industrial wastewater remains a critical global environmental concern. In this study, an Al/Mg/Zr-MOF (AMZ-MOF) was synthesized via a solvothermal method and systematically evaluated for Cr (VI) removal from aqueous solutions. Comparative analysis demonstrated that AMZ-MOF exhibited superior Cr (VI) removal efficiency relative to pristine Zr-MOF, Mg/Zr-MOF, and Al/Zr-MOF. The synthesized AMZ-MOF composite was subjected to comprehensive characterization using FESEM, TEM, XRD, BET, FTIR, and XPS analyses. The study systematically investigated the influence of key operational parameters, including contact time, temperature, pH, and initial Cr (VI) concentration, on the composite’s sorption behavior. AMZ-MOF demonstrated exceptional performance, achieving a maximum Cr (VI) sorption capacity of 185.2 mg/g. Remarkably, the sorbent exhibited rapid initial uptake kinetics, reaching adsorption equilibrium within 120 min. Mechanistic insight was gained through adsorption isotherm and kinetic modeling, revealing that the process is best described by the Langmuir isotherm and the Pseudo-Second-Order kinetic model, suggesting monolayer adsorption onto a heterogeneous surface and chemisorption as the rate-limiting step, respectively. Further FTIR and XPS analyses corroborated the proposed sorption mechanism, clarifying the key functional groups and surface interactions involved in Cr (VI) removal. The proposed adsorbent demonstrated excellent reusability over five adsorption–desorption cycles, underscoring its stability and practical potential for Cr (VI) remediation.

Elemental doping plays a crucial role in optimizing carrier concentration and suppressing lattice thermal conductivity in thermoelectric materials. In this study, Cu atoms were doped in both n- and p-type Mg 3 Sb 2 -based thermoelectric compounds. The results indicate that the incorporation of Cu effectively improves the electrical transport properties of Mg 3 Sb 2 -based thermoelectric compounds while simultaneously suppressing their thermal transport, ultimately achieving enhanced thermoelectric properties: (a) For p-type Mg 3 Sb 2 , a small quantity of Cu atoms provides electrons in the lattice interstitial and thus compensates holes, leading to a decreased carrier concentration and electrical conductivity. However, with increasing Cu content, Cu atoms preferentially occupy Mg2 sites, thereby increasing hole concentration, and thus improving electrical conductivity. Further increasing Cu content, an MgCuSb secondary phase forms, which is unfavorable for overall p-type thermoelectric performance of the Mg 3 Sb 2 -based matrix due to the n-type transport of the MgCuSb compound. (b) For n-type Mg 3 Sb 2 , no such secondary phase was observed despite the same Cu-doping content, which involves a distinct doping mechanism from the p-type one. Consequently, the zT values of p-type Mg 3 Sb 2 materials are improved by 17%–33% over the whole temperature range. And regarding the n-type Mg 3 Sb 2 materials, the highest peak zT value of ~1.4 and average zT avg of ~1.04 are achieved. Therefore, the doping of the Cu element proves to be an effective way in optimizing thermoelectric properties of both p-type and n-type Mg 3 Sb 2 -based materials.

In this investigation, Si nanoparticles are anchored onto a multi-level carbon structure (C-MSZSZ) derived from a heterogeneous MOF. The hierarchical carbon layers strongly bind the Si nanoparticles, providing sufficient void space to accommodate volume expansion during cycling. Additionally, the creation of trimetallic active centers and carbon defects boost electrical conductivity and Li + transport kinetics. The presence of abundant open channels within the carbon matrix also facilitates the transfer of electrons and ions, thereby leading to a promoted electrochemical reaction process. As a result, the battery harvests a high reversible capacity of 1035.7 mA h g –1 at 0.5 A g –1 after 200 cycles, along with remarkable rate capability. The delicate design of multi-level carbon architecture offers a promising strategy for the development of advanced anode materials aimed at achieving high-performance LIBs. Based on a delicate “layer-by-layer” assembly strategy, the silicon anode shows a robust structural integrity and favorable performance owing to the significantly relieved volume expansion and optimized electron/ion transport kinetics.

Carbon materials are extensively employed in chemical production for the selective oxidation of aromatics. In this study, the activated carbon nanomaterial catalyst significantly enhanced the oxidation reaction efficiency of cumene while promoting the high conversion of cumene peroxide (CHP) to 2-phenyl-2-propanol (PP). The carbon synthesised from furfural residue (C-F) achieved a 39.48% cumene conversion and 54.95% PP selectivity, representing the most outstanding catalytic performance among all catalysts studied. The structural characteristics of the synthesised catalyst were systematically analysed using TEM, XPS, BET, and Raman spectroscopy. Furthermore, comparative experiments confirmed that oxygen-containing functional groups on the activated carbon surface inhibit the oxidation reaction of cumene. Mechanistic studies indicate that the decomposition of CHP constitutes a key step in the oxidation process of cumene.

Co 3 O 4 exhibits a high theoretical specific capacity and excellent lithium storage performance, making it a promising lithium-ion battery anode. Nonetheless, its high cost, low intrinsic conductivity, and significant volume change during cycling hinder its widespread application. In this study, Co sites in the spinel Co 3 O 4 was partially substituted with eco-friendly and low-cost Fe to form the bimetallic oxide FeCo 2 O 4 . To enhance conductivity and stabilize the oxide material, reduced graphene oxide (RGO) was incorporated to serve as both a conductive matrix and a mechanical buffer, anchoring the FeCo 2 O 4 nanoparticles to mitigate volume expansion/contraction. The uniform dispersion of FeCo 2 O 4 nanoparticles loaded on the layered RGO architecture was achieved through a facile solvothermal method, effectively mitigating nanoparticle agglomeration and RGO restacking. This approach facilitated the orderly arrangement of FeCo 2 O 4 and enhanced the cycling stability of the electrode. Additionally, the high conductivity of RGO provided efficient pathways for ion and electron transport, further boosting the overall electrochemical performance of FeCo 2 O 4 . At an optimal FeCo 2 O 4 /RGO mass ratio of 10:1, the composite demonstrated an initial specific discharge capacity of 1092.4 mAh g − 1 at 0.5 C, significantly outperforming pure FeCo 2 O 4 (859.2 mAh g − 1 ) under the same conditions. The anchoring effect of RGO substantially enhanced the electrochemical performance of FeCo 2 O 4 . This work underscores the efficacy of synergistic composite design and provides a practical approach for developing advanced bimetallic oxide anodes for high-energy-density lithium-ion batteries.

A novel Schiff Base as a flame-retardant monomer (FSB, 5-((3,5-bis(trifluoromethyl) benzylidene) amino) isophthalic acid) with -CF 3 was designed and used to synthesize FSB n PETs (PET copolyester) by copolymerization, which shows good flame retardancy and anti-dripping. The introduction of the –CF₃ group increases the cyclization temperature of the FSB Schiff base unit by suppressing the cyclization reaction through its strong electron-withdrawing effect, which is 350–398 °C, higher than 250–348 °C from the PET copolyesters modified by Schiff Base without -CF 3 , indicating that FSB n PETs exhibits a broadened processing temperature window. And FSB also increased the glass transition temperature (Tg), reduced the melting temperature (Tm) and the crystallizability of FSB n PETs. FSB n PETs possessed good flame retardancy and anti-dripping properties, FSB 10 PET (7.4 mol% of FSB) owned V-0 level of UL-94 and 31% value of LOI without dripping phenomenon. The bond of -C-F had not broken into the air phase to make an obvious influence on the flame retardancy property of FSB n PETs, whose flame retardancy mechanism is still type of the condense flame retardancy. Additionally, in the new preparation process for FSB n PETs, the dicarboxylic acid structure of FSB could speed up the condensation polymerization between the BHET precursors, which could save 50% of the preparation time, showing an exciting economic advantage. The -CF₃ modified Schiff base (FSB) is an effective modifier for PET copolyesters, offering improved processing performance and good flame-retardant properties.

The development of efficient and economical photocatalysts is the focus of achieving sustainable remediation of water pollution. However, slow photogenerated carrier transfer and insufficient catalytic sites are the main reasons affecting photocatalytic applications. Herein, we developed flake-octahedral BiOBr/MIL-101(Fe) heterojunction catalysts through a facile solvothermal strategy for the degradation of pollutants under visible light irradiation. Scanning electron microscope, X-ray photoelectron spectrometer, Fourier infrared spectrometer, and X-ray diffraction analysis characterizations proved the successful synthesis of flake-octahedral BiOBr/MIL-101(Fe) heterojunction. Absorption spectra and Brunauer–Emmett–Teller analyses showed that the BiOBr/MIL-101(Fe) composites with an atomic percentage of Fe of 9.1 (denoted as BiOBr/MIL III ) had the optimal light absorption and the largest specific surface area. The BiOBr/MIL III achieved a remarkable Rhodamine B (Rh B) degradation efficiency of 94.5% within 60 min, with an apparent rate constant ( k ) of 0.03540 min −1 , demonstrating excellent visible light-driven photocatalytic activity. Photocatalytic mechanistic studies showed that the solvothermal-induced flake-octahedral BiOBr/MIL-101(Fe) III heterojunction promotes the formation of Z-scheme, which significantly enhances the carrier separation efficiency and accelerates the rapid generation of reactive radicals · O 2 − and h + . This work provides a feasible strategy for the construction of flake-octahedral inorganic-MIL photocatalysts with excellent photocatalytic performance.
