Due to the strong adhesiveness of polydopamine, Ag + can be fixed on the surface of the cotton fabric. Then, through the self-organization of octadecyltrichlorosilane (ODTS), a superhydrophobic and a superoleophilic cotton fabric can be obtained. A scanning electron microscope (SEM), a Fourier transform infrared spectrometer (FTIR), a thermogravimetric–differential thermal analyzer (TG), and a contact angle measuring device are used to evaluate the surface morphology and wettability of the cotton fabric. From the results of the contact angle and the surface wettability, it is found that the modified cotton fabric shows excellent hydrophobicity. The contact angle with water can reach 156.8°. Water droplets can stay spherical on its surface for a long time without spreading or wetting the fabric. Furthermore, it also exhibits good lipophilicity and can quickly absorb oil droplets that land on its surface. The fabricated fabric can effectively achieve oil–water separation through the action of gravity. The separation efficiency for various types of oil–water separation exceeds 98% and can reach a maximum of 99.89%. Additionally, the superhydrophobic cotton fabric also has the ability to separate water-in-oil emulsions with different volume ratios more effectively. The modified fabrics can inhibit the growth of E. coli and S. aureus , showing good antibacterial properties.

Hot melt adhesives are utilized in a variety of industries because to their solvent-free, strong adhesion and rapid curing. With the increasing awareness of environmental protection, biodegradable hot melt adhesives have received attention. Herein, chlorinated poly(propylene carbonate) (CPPC)/poly(butylene succinate) (PBS)/poly(lactic acid) (PLA) blends were prepared using diphenylmethane diisocyanate (MDI) as reactive compatibilizer. Thermogravimetric analysis (TGA) demonstrated that adding PLA improved the thermal stability of the blends. From rheological tests, the melt elasticity and viscosity of the blends at 170 ℃ were enhanced after PLA was added. The tensile strength of CPPC/PBS/PLA/MDI blends reached 47.9 MPa as 32 wt% of PLA was added. When PLA content was 16 wt%, the blends exhibited high adhesion strength (13.97 MPa), which was much higher than that of common commercial products. In addition, the enzymatic degradation tests showed that the blends had biodegradability. Therefore, CPPC/PBS/PLA/MDI blends have the potential to be used in biodegradable hot melt adhesives. Graphical CPPC/PBS/PLA/MDI blends with different PLA contents were prepared by in situ compatibilization. The biodegradable CPPC/PBS/PLA/MDI blends had good mechanical and adhesive properties.

As a bio-based environmentally friendly material, microcrystalline cellulose (MCC) can be applied to automotive trims instead of traditional plastics; However, its flammable properties limit the application scope. In this paper, a multi-component environmentally friendly and efficient halogen-free flame retardant (APMMCC) was prepared by amino silicone oil (ASO)/phosphoric acid (H 3 PO 4 )/melamine (MEL) co-modification. The synergistic modification not only made the surface morphology of microcrystalline cellulose smoother, but also introduced ASO molecules, phosphoric acid and melamine groups, which altered its chemical structure. Thermal degradation tests showed that the thermal stability and char-forming ability of APMMCC were greatly improved. Compared with MCC, APMMCC had stronger combustion-resistance under the flame and showed significant flame retardancy. When the addition content of MCC and MEL is 1:1, the heat release rate, total heat release rate, and smoke release rate of APMMCC were minimized in the current research range. Moreover, the residual char of APMMCC at different temperatures was analyzed by Fourier transform infrared, and a condensed phase and gas phase synergistic flame retardant mechanism was proposed.

Arsenic (As) contamination in water supplies poses severe risks to human health and ecosystems, necessitating high-efficiency, regenerable, and cost-effective adsorbents. In this study, a bimetallic layered double hydroxide hybrid (MnFe-LDH/BC@H3BTC) was constructed using biochar (BC) and 1,3,5-benzenetricarboxylic acid (H3BTC) as a ligand-regulated structure for enhanced arsenite [As(III)] removal. MnFe-LDH/BC@H3BTC exhibited 99.4% As(III) removal at pH 7 within 2 h equilibrium, showed superior adsorption capacity (2.99 mgg −1 ) compared to MnFe-LDH (2.2 mgg −1 ) and MnFe-LDH/BC (2.58 mgg −1 ). Characterization (XRD, FTIR, 2D-COS, BET, and XPS) revealed synergistic contributions from redox-active Mn²⁺/Mn³⁺ and Fe²⁺/Fe³⁺, ligand exchange with -OH and -COOH groups, and a BET surface area enhancement from 4.15 to 122.17 m 2 g −1 . Kinetic and isotherm modelling followed pseudo-second-order (R²=0.99) and Langmuir monolayer adsorption, confirming a chemisorption mechanism. HPLC speciation demonstrated time-resolved As(III) to As(V) oxidation. Real water application tests confirmed 2.82 mg g −1 As(III) removal, and regeneration studies confirmed high stability over five cycles with minimal metal leaching. This study provides a scalable, multifunctional strategy for As(III) remediation and contributes to understanding ligand-mediated redox-adsorption mechanisms in hybrid sorbents. Graphical The graphical abstract presents a visual summary of the synthesis, mechanistic pathways, and real-world performance of MnFe-LDH/BC@H3BTC for efficient arsenic removal from contaminated water. In the Preparation phase, manganese-iron layered double hydroxide (MnFe-LDH) is integrated with biochar and functionalized using trimesic acid (H3BTC), forming a porous and reactive hybrid structure. This composite material is engineered to provide abundant active sites for interaction with arsenic species. The Oxidation and Removal section details the mechanistic transformations involved in arsenic remediation. Arsenite (As(III)) undergoes oxidation to arsenate (As(V)) facilitated by redox-active Mn species, while multiple removal pathways electrostatic attraction, ligand exchange, complexation, and hydrogen bonding-contribute to the stable immobilization of arsenic on the material surface. This segment depicts the transformation and sorption processes, emphasizing the synergy between functional groups and structural components. In the Performance section, experimental data show that MnFe-LDH/BC@H3BTC achieves rapid removal of As(III), with a sorption efficiency of 99.4% within just 2 h, outperforming the individual or partially modified components. The MnFe-LDH/BC@H3BTC composite demonstrates excellent potential as a practical and scalable solution for arsenic remediation in real water systems, offering a combination of rapid kinetics, high efficiency, and multifunctional removal mechani

The structural instability and electronegativity of sialic acids make N-sialoglycan profiling challenging. We compared commonly used preparation strategies, including native, acetohydrazide-based derivatization, and permethylation, in N-glycomics with nMatch, an R-based bioinformatics tool that ensures full coverage of the detected N-glycans using mass spectrometry. We demonstrated that permethylation leads to efficient detection of not only N-sialoglycans but also other N-glycans and, therefore, provides a valuable reference for the selection of the appropriate N-glycan preparation strategy in future studies.

In this work, we prepared an innovative nanocomposite by integrating stellate monodisperse mesoporous silica nanospheres (SMMS) into the high-purity whisker carbon nanotubes (WCT) networks through an efficient ultrasonic-assisted process. This nanocomposite was employed as sensing sensitizer to modify glassy carbon electrode (GCE) for the fabrication of highly sensitive WCT@SMMS/GCE sensing platform for electrochemical analysis of gallic acid (GA). SMMS showed more complex and richly connected pore structure with large pore size and high porosity, which might be beneficial for the adsorption of GA. WCT with good dispersibility could enhance the efficiency of charge transport. Moreover, WCT with multi-layered hollow structure had extremely high electrolyte adsorption capacity, which promoted the penetration of electrolyte for the efficient enrichment of GA molecules on electrode surface. The WCT@SMMS/GCE sensor demonstrated excellent GA electrochemical detection performance (LOD: 8.99 nM, GA concentration: 0.1–20 µM). Additionally, the developed sensor with good repeatability and anti-interference performance obtained satisfactory recovery rates of 94.08–104.78% and RSD values of 1.34–4.84 for the GA quantitative analysis in food samples.

Extracting Al from coal gangue has the double benefits of realizing the high-value application of coal gangue and mitigating the scarcity of bauxite resource. The key Al-containing minerals in coal gangue include kaolinite and boehmite, and thermal activation is pivotal for stimulating their reactivity. In this study, kaolinite and boehmite were subjected to thermal activation and acid leaching to explore the intrinsic link between their thermal evolution and leaching activity. Results showed that the phase evolution of kaolinite followed a multi-step sequential process in the order of kaolinite → metakaolinite → γ -Al 2 O 3 → mullite, and Al V in metakaolinite was highly active. For boehmite, it underwent the transformation of boehmite → γ -Al 2 O 3 → δ -Al 2 O 3 → θ -Al 2 O 3 and α -Al 2 O 3 successively. Their reactivity in descending order was γ -Al 2 O 3 > δ -Al 2 O 3 > boehmite > α -Al 2 O 3 . Furthermore, a comparative study of leaching temperature demonstrated that elevated temperature favorably strengthened the thermodynamic driving force and greatly promoted the Al extraction. This study is of some theoretical significance for guiding the thermal activation and acid leaching of coal gangue. Graphical

With the depletion of high-quality nickel sulfide ore resources, the reliance on laterite nickel ore as a primary raw material for nickel production has increased. The pyrometallurgical process for laterite nickel ore mainly yields ferronickel, which is used predominantly in stainless steel production and falls short of the needs of the burgeoning new energy sector. Consequently, there is an urgent need to develop a new process for producing nickel matte through sulphidizing smelting of laterite nickel ore. The study examines the impact of various parameters, including the sulfurizing agent, reducing agent, flux, and the proportion of ore, on the slag liquidus temperature and nickel and cobalt recovery ratios. The findings reveal that when maintaining the original system with a m (SiO2) /m (MgO) ratio of 1.2, the slag composition remains outside the liquid phase region when altering the CaO content. Increasing the CaO content expands the m (SiO2) /m (MgO) value range for the slag composition within the liquid phase region. Optimized conditions show that with an m (SiO2) /m (MgO) ratio of 2.5, 10 pct CaO addition, 6.5 pct sulfiding agent addition, 4 pct reducing agent addition, p O 2 at 10 −9 atm, and an SO 2 gas flow rate of 4 mL/min, the nickel and cobalt recovery ratios reach 98.72 and 81.92 pct, respectively. Most of the iron transitions to the slag phase, with 79.80 pct entering the slag and 20.20 pct remaining in the nickel matte. The resulting nickel matte contains 19.41 pct Ni, 0.84 pct Co, and 28.39 pct S, primarily comprising nickel-iron, nickel matte, and iron matte phases.

Polymer solid-state electrolytes hold significant promise for all-solid-state lithium-ion batteries, but they also suffer from critical limitations including high flammability, low ionic conductivity, and poor mechanical properties. In this work, aluminum phosphate (AlPO 4 )-coated silica (SiO 2 ) (SiO 2 @AlPO 4 ) synergistic flame retardant was fabricated, and the influence of SiO 2 @AlPO 4 on the mechanical properties, the flame retardancy, and the ionic conductivity of poly(ethylene oxide) (PEO)/Li salt ionic conductor was studied. For PEO/Li/SiO 2 @AlPO 4 10 composite electrolyte, the strength and the modulus increased by 38.5% and 80.7%, respectively, compared with PEO/Li electrolyte, and the ionic conductivity almost was the highest among all samples in the entire temperature rang. For all PEO composite electrolytes, the limiting oxygen index (LOI) increased and the total heat release (THR) reduced with the increase of SiO 2 @AlPO 4 content. Results show that SiO 2 @AlPO 4 can not only improve the strength, the modulus, and the flame retardancy of PEO but also improve its ionic conductivity, the SiO 2 @AlPO 4 was demonstrated as an excellent synergistic filler for PEO solid-state electrolytes.

Terpene phenolic resin with high softening point and strong adhesion has been increasingly studied worldwide, and it is widely used in the field of rubber and adhesives. A low-cost and easy-to-prepare heterogeneous catalyst, silica-loaded perchloric acid (HClO 4 /SiO 2 ), was prepared from perchloric acid and fumed silica, and utilized to synthesize terpene phenol resins for the first time. The polymerization conditions were optimized by single factor experiments, and the terpene phenol resin obtained under the optimal conditions achieved a yield of 85.1%, a softening point of 112.6 °C, a Ghanaian color number of 8, and an acid value below 1.00 mg KOH g −1 without washing with water, respectively. The possible copolymerization mechanism was inferred through other characterization methods such as infrared spectrum and hydroxyl value determination. After three cycles of the polymerization, the catalyst HClO 4 /SiO 2 still achieved a relative high yield of 65.2%, and no significant desorption for perchloric acid was observed. This means that the washing with water to remove desorbed perchloric acid in the resin can be avoided, which may prevent wastewater pollution to the environment, save production costs and simple production process. Therefore, HClO 4 /SiO 2 presents a promising option for the clean and cost-efficient production of terpene phenolic resins, with potential applications in large-scale manufacturing.

Objective By establishing a mouse model of hepatic ischemia–reperfusion injury (HIRI), to investigate the effects of cyclooxygenase-2 (COX-2) and endoplasmic reticulum stress (ERS) on HIRI and their interaction in HIRI. Methods C57BL/6J male mice were divided into four groups: Sham operation group (Sham group), hepatic ischemia–reperfusion (HIR) group, hepatic ischemia–reperfusion + Salubrinal (ER stress inhibitor) pretreatment group (HIR + Sal group), hepatic ischemia–reperfusion + NS398 (inhibitor of COX-2) pretreatment group (HIR + NS398 group). The levels of Aspartate transaminase (AST) and Alanine transaminase (ALT) in serum, the activity of Super Oxide Dismutase (SOD) and the content of malondialdehyde (MDA) in liver tissue were detected. The mRNA and protein expression of Glucose-regulated protein 78 (GRP78), C/EBP homologous protein (CHOP), phosphorylated eukaryotic translation initiation factor 2α (p-eIF2α) and COX-2/PTGS (Prostaglandin-endoperoxide synthase) in liver tissue were detected. The morphological changes and apoptosis of liver tissue were observed. Results Compared with the Sham group, the serum ALT and AST levels of the HIR group were increased, the SOD activity in the liver tissue was decreased, the MDA content and the expression of COX-2, p-eIF2α, GRP78 and CHOP protein were increased, and the staining results showed that hepatic sinusoidal congestion, a large number of hepatocyte death, inflammatory cell infiltration and apoptotic cells were significantly increased. The levels of ALT and AST decreased after Sal or NS398 pretreatment. SOD activity was increased, MDA content, COX-2, GRP78, CHOP mRNA and protein were decreased in liver tissue, and staining showed that liver tissue injury was improved. Conclusion In mice with HIR, COX-2 interacts with ERS to cause liver injury by regulating oxidative stress and apoptosis.

Covalent organic frameworks (COFs) are ideal for precious metal recovery due to their high surface areas and tunable binding sites. However, the confinement of binding sites within inner pores often leads to restricted mass transfer, resulting in poor site accessibility and limited extraction capacities. Herein, we report a quasi-two-dimensional (quasi-2D) topology-directed strategy to construct exposed binding sites for highly efficient gold recovery. By incorporating outward-pointing hydroxyl groups, the local conformation of the imine-linked skeleton is effectively locked via inter-chain hydrogen bonding (ICHB), which suppresses molecular torsion and promotes ordered assembly of the 1D chains into a quasi-2D crystalline architecture. This structural rigidification creates unobstructed ion-diffusion pathways and maximizes the exposure of active sites for rapid [AuCl 4 ] − capture and reduction. Remarkably, under mild thermal and vibratory stimulation, gold nanoparticles form in situ and aggregate, yielding a high gold extraction capacity of 5082.32 mg g −1 . Theoretical calculations demonstrate that ICHB-induced structural planarization creates a cooperative coordination environment and optimizes the energetic landscape for dechlorination, synergistically promoting guest enrichment and interfacial gold reduction. This work establishes a new blueprint for creating COFs with exposed active sites via inter-chain assembly, offering a scalable approach to maximize site accessibility and electron transfer for selective gold capture.
