Encapsulation is a crucial technology for isolating and protecting moisture-sensitive materials. However, traditional organic-inorganic composite films often exhibit poor adhesion at the interface and high gas permeability, making stable operation difficult. In this work, an enhanced atomic layer deposition (EALD) method was used to uniformly deposit a layer of thickness-controlled alumina on a Polyethylene Naphthalate (PEN) film with oxygen-containing polar groups(CTPEN) on its surface, successfully producing a high-barrier composite film (EALD-Al 2 O 3 /CTPEN) with Al-O-C chemical bonds. The designed CTPEN film significantly enhanced the adhesion of alumina, thereby improving the performance of the composite film. Moreover, the mechanical properties of the composite film were significantly enhanced, with the elongation at break of EALD-Al 2 O 3 /CTPEN at 72 % being considerably higher than that of ALD-Al 2 O 3 /PEN at 44 %, and the tensile strength reaching 220 MPa. At the same time, EALD-Al 2 O 3 /CTPEN maintained excellent light transmission, exceeding 85 %. Humidity -sensitive resistors encapsulated with EALD-Al 2 O 3 /CTPEN exhibited stable operating performance in both air and humidity-sensitive environments, confirming the superior barrier properties of the composite film. This EALD-Al 2 O 3 /CTPEN composite layer holds promise as a prospective encapsulation layer for future flexible devices.

A palladium catalyzed selective mono-chlorination of o -carboranes has been developed by utilization the oxidizability of FeCl 3 , and a series of mono-chlorinated o -carboranes with active groups have been synthesized with moderate to good yields as well as good selectivity. A plausible mechanism involving the electrophilic palladation of B-H bond and the Pd(II)/Pd(IV) catalytic cycle was proposed. Graphical One stone two birds: By utilization the dual role of FeCl 3 with oxidizability and chlorine source, the selective mono-chlorination of o -carboranes on B(9) and B(8) have been developed. The concept that FeCl 3 only as a Lewis acid in promoting the electrophilic halogenation of carboranes has been changed.

The alkylation of unsaturated organic and aromatic hydrocarbons represents a pivotal class of synthetic reactions with significant implications in both industrial and academic research. Furthermore, cyclohexylbenzene, synthesized via the alkylation of benzene with cyclohexene, represents a high-value-added fuel additive owing to its exceptionally high cetane number. However, it still remains challenging due to the insufficient activation of double bond-containing organic substrate over traditional phosphotungstate catalysts. In this study, we develop a single Pt atom doped phosphotungstate, as Pt 1 -NH 4 -PW catalyst, through a coprecipitation method, for the alkylation of cyclohexene with benzene. Compared to pristine NH 4 -PW, Pt 1 -NH 4 -PW catalyst consists of the electronic reconstructed Pt 1 -O pair coordinated with [PW 12 O 40 ] 3− . Such structure shows a typical synergistic interaction characteristic, where the Pt atom of the Pt 1 -O structure serves as a Lewis acid site to accept the electron from the C=C bond, and the nearby O functions as hydrogen acceptors to promote C–H bond activation of benzene. Consequently, the Pt 1 -NH 4 -PW catalyst demonstrates a threefold enhancement in catalytic activity compared to NH 4 -PW for the alkylation of cyclohexene with benzene. The catalytic system further demonstrated exceptional performance in diverse transformations, including alkylation of benzene with either 1-hexene or 1-dodecene, and conversion of biomass-derived methyl oleate into high-value chemicals through alkylation.

Oxygen vacancies (Ov) are crucial for modulating electronic structures and catalytic properties. Herein, a vacancy-rich HEDP-MoV heteropoly acid catalyst was synthesized via one-pot hydrothermal method by vanadium substituting molybdenum in phosphomolybdic acid with HEDP as support, focusing on Ov’s role in enhancing oxidative desulfurization (ODS) efficiency. XPS and EPR analyses showed vanadium incorporation (less electronegative than Mo) modulated Mo 5+ /Mo 6+ ratio and linearly increased Ov content from 28.65% (HEDP-Mo 10 V 2 ) to 41.81% (HEDP-Mo 7 V 5 ), promoting electron transfer and activity. The HEDP-MoV system exhibited superior H 2 O 2 activation and ·OH generation, with DBT desulfurization rate 41.6% higher than unsubstituted HEDP-Mo. The optimized HEDP-Mo 7 V 5 achieved 99.1% DBT desulfurization at O/S=3 and 30 o C (milder than most reported PMoV catalysts requiring O/S≥5) and retained 98% activity after 10 cycles. Radical quenching and EPR confirmed ·OH as dominant reactive species, while DFT verified H 2 O 2 dissociation thermodynamics. This study highlights vanadium substitution as an effective defect engineering strategy for HPA catalysts and provides a scalable pathway for mild-condition ultra-deep diesel ODS.

Cyanidin-3- O -glucoside (C3G), a promising flavonoid with diverse biological properties, faces challenges in functional food application due to instability under various conditions. Therefore, this study aimed to develop a novel gum Arabic-coated nano-nutriosome (GA-C3G-NU) for promoting gastro-intestinal (GI) delivery of C3G and fortification of set-type yogurt (Ygr). The GI digestion study revealed that GA improved the stability of C3G-NU. After freeze-drying, FZD GA-C3G-NU maintained their nanosized, exhibited high encapsulation efficiency ≥90%, and an acceptable PDI ≤0.30. SEM analysis revealed crystal-like structure in GA-C3G-NU, while the XRD study confirmed their decreased crystallinity. Furthermore, the FZD GA-C3G-NU showed significantly controlled release profile ( p < 0.05) of C3G. The GA-C3G-NU didn't negatively affect the yogurt's properties. It maintained the desirable acidity while enhancing water holding capacity, color, texture, microstructure, and compatibility with lactic acid bacteria. Overall, GA-C3G-NU could be a promising carrier for enhancing C3G's gastrointestinal delivery, with potential use in dairy products.

Loofah sponge carbon (LOC) was employed as a three-dimensional scaffold and magnetized through alkaline hydrothermal treatment followed by co-precipitation to obtain magnetic loofah sponge carbon (MLOC). Subsequent lanthanum incorporation produced La₃-MLOC, which integrates a hierarchically porous architecture with magnetic separability for phosphate removal from complex waters. La₃-MLOC delivered a Langmuir capacity of 117.32 mg/g at pH 3 and showed rapid uptake across pH 3–6, achieving > 90% removal within 15–40 min while maintaining good tolerance to common coexisting ions. Kinetic fitting (PSO and Avrami, n ≈ 0.82) suggests a predominantly site-specific chemisorption pathway. Microscopic and spectroscopic analyses support La–OH-mediated hydroxyl displacement/inner-sphere complexation, accompanied by partial LaPO₄ precipitation. The sorbent retained high performance over four adsorption–desorption cycles (removal about 92%; desorption about 77%). When evaluated using real effluent from a coal-mining subsidence outfall, La₃-MLOC enabled low-level phosphate polishing to Class III targets at low dosage and short contact time, with an estimated treatment cost of 0.341 USD/g, indicating its potential for end-of-pipe phosphate control and resource-oriented management.

Abstract This study addresses the problems of strong temperature dependence, low demulsification efficiency, and long treatment time for oil-in-water (O/W) emulsions in the petroleum industry. Using polyethylene glycol/polyethylene glycol monomethyl ether (PEG/mPEG) as the hydrophilic polyether backbone, a novel amphiphilic polyether ester–amide demulsifier PEOSu-C18 was designed and synthesized by succinic acid esterification and terminal modification with octadecyl amide to introduce hydrophobic octadecyl-amide segments at polymer chain ends. The linear polyether-ester backbone supplies interfacial adsorption capacity, while terminal long-chain octadecyl hydrophobic segments provide effective interfacial displacement and hydrophobic interactions. Demulsifier dosage, temperature, time, and pH were systematically studied for oil-removal performance. PEOSu-C18 achieved an oil-removal efficiency above 98% within 30 min at a low dosage of 100 mg/L. It maintained excellent performance over a wide temperature range (30–60 °C) and possessed favorable salt tolerance, which can cut the energy and time costs of traditional demulsification. PEOSu-C18 was characterized via FTIR and 1H NMR. Its demulsification mechanism was explored by dynamic interfacial tension, Zeta-potential, and optical microscopy. Results reveal that PEOSu-C18 rapidly migrates to the oil–water interface, competes with and displaces negatively charged kaolinite particles through steric hindrance and hydrophobic interaction, breaks the rigid interfacial film, and accelerates oil-droplet coalescence. This work provides an efficient, rapid, and energy-saving demulsifier with promising prospects for complex oilfield-produced-fluid treatment.

Spintronic catalysis remains largely unexplored for the oxygen evolution reaction (OER). Herein, we propose a novel spin-control strategy by constructing an oriented, 1D core-shell CoB@Ni(OH) 2 nanochain architecture. The spin-ordered amorphous ferromagnetic (FM) CoB core effectively induces spin polarization in the antiferromagnetic (AFM) Ni(OH) 2 shell via FM@AFM coupling. Combined experimental and theoretical analyses reveal that an applied magnetic field (MF) induces spin alignment in Ni(OH) 2 . This MF-guided spin alignment triggers directional Ni orbital splitting, promotes d-charge accumulation at Ni–O sites, and activates a switch to the highly efficient lattice oxygen mechanism. Consequently, the CoB@Ni(OH) 2 catalyst achieves a low overpotential of 472 mV at 100 mA cm -2 and exhibits stability exceeding 150 h under an MF, markedly outperforming its non-magnetic operation. This work demonstrates that engineering FM@AFM interfaces enables the transformation from spin disorder to spin alignment, opening a new avenue for spin-regulated electrocatalytic material design.

Lignin-enabled Si–O/carbon nanofibrous membranes were developed for harsh-condition oil/water separation. • Lignin contributed to defect-rich carbon framework formation and interfacial functionality. • The optimized membrane showed foldable flexibility, underwater superoleophobicity, and > 99% separation efficiency. Lignin, an abundant aromatic biological macromolecule, is an attractive sustainable precursor for functional carbon materials, yet its structure-directing role in high-performance separation membranes remains insufficiently exploited. In this work, lignin-enabled Si–O/carbon hybrid nanofibrous membranes were fabricated by electrospinning polyacrylonitrile/lignin/tetraethyl orthosilicate (PAN/lignin/TEOS) precursor solutions, followed by controlled stabilization and carbonization. During thermal conversion, lignin contributed to the formation of defect-rich carbon domains and polar interfacial characteristics, while TEOS-derived amorphous Si O phases helped regulate framework evolution, suppress structural collapse, and buffer local stress concentration. As a result, the optimized membrane developed a biomimetic brick-and-mortar-like hybrid architecture with multiscale porosity, foldable flexibility, rapid water infiltration, and strong underwater oil repellency. The membrane exhibited underwater oil contact angles above 150°, achieved separation efficiencies above 99% for surfactant-free oil/water mixtures with a water flux of 1299.36 L·m −2 ·h −1 under gravity-driven conditions, and also efficiently separated SDS-stabilized oil-in-water emulsions. Moreover, it maintained stable performance after repeated cycling, prolonged storage, and treatment under cold, hot, acidic, and alkaline conditions. This study highlights lignin not only as a sustainable carbon source, but also as a functional macromolecular component for constructing robust hybrid nanofibrous membranes for harsh-environment oil/water separation.

BiOCl and its derivatives show considerable promise for supercapacitor applications because of their high theoretical specific capacity and rich redox activity. However, their practical performance is often limited by poor electrical conductivity and structural instability. To address these issues, we constructed a BiOCl/Bi₂₄O₃₁Cl₁₀ heterojunction to improve both charge transport and structural stability. A flake-like BiOCl precursor was first synthesized and then electrochemically treated at a constant current of 0.02 A over a wide pH range (1−13) to generate a BiOCl/Bi₂₄O₃₁Cl₁₀ heterojunction, denoted as BiOCl-1/24-X. By tuning the pH of the reaction system, pH-dependent formation of a reconstructed Bi₂₄O₃₁Cl₁₀ phase on the BiOCl surface was achieved, thereby strengthening the interfacial interaction between the two phases. This interfacial reconstruction process modulated the extent of heterointerface formation and the concentration of oxygen-vacancy-related defects, thereby promoting ion transport and charge-transfer kinetics. The results indicate that the sample treated at pH = 9 exhibits battery-type energy-storage behavior dominated by diffusion-controlled processes. Accordingly, it delivered a specific capacity of 411C·g −1 at 1·A g −1 , far exceeding that of pristine BiOCl (80C·g −1 ). Moreover, it retained 79.3% of its initial capacity after 10,000 cycles. It also achieved an energy density of 35.67 Wh·kg −1 at a power density of 923.83 W·kg −1 . In a practical demonstration, the BiOCl-1/24//AC device powered a 3.2 V LED for 900 s, highlighting its application potential. This work proposes a facile electrochemical interfacial reconstruction strategy for developing high-performance electrode materials, offering a simpler and more effective alternative to conventional chemical methods.

As a vital chemical intermediate, o-cresol is integral to many high-value manufacturing processes. Its synthesis via the methylation of phenol using methanol represents a green and atom-efficient route. Despite exhibiting promising ortho -selectivity, conventional α-Fe 2 O 3 catalyst are often limited by insufficient activity under mild conditions, restricting their practical utility. To address the limited catalytic efficiency of conventional α-Fe 2 O 3 in low-temperature o-cresol synthesis, a nano α-Fe 2 O 3 catalyst was fabricated using a polyethylene glycol (PEG) assisted precipitation method. The catalyst was comprehensively characterized using XRD, N 2 physisorption, TEM, NH 3 -TPD, XPS and EPR. These analyses elucidated the role of PEG in the catalyst synthesis, demonstrating that the PEG-assisted method significantly enhances specific surface area, acidity and oxygen vacancies, thereby collectively improving catalytic performance. Compared to α-Fe 2 O 3 , the novel catalyst achieved a significantly higher phenol conversion of 15.8 % versus 8.5 % under 340 °C and 3 h −1 . Furthermore, the amount of PEG added in the assisted precipitation process was optimized and the mechanism of the phenol methylation reaction over 2.5PEG/α-Fe 2 O 3 was clarified. The results provide a basis for designing efficient catalysts, thereby facilitating their industrial application in o-cresol production.

Non-metallic photocatalysts represent a promising avenue for the green remediation of organic wastewater. In this study, O-doped g-C 3 N 4 (OCN) was synthesized using a one-step calcination strategy and synergistically coupled with periodate (PI) under visible light to develop a novel non-radical OCN/PI/Vis photo-Fenton-like system for the efficient degradation of Acid Orange 7 (AO7). Systematic characterization techniques, including transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS) and photoluminescence (PL), along with density functional theory (DFT) calculations, were employed to elucidate the catalyst properties, oxidant adsorption, and reaction mechanisms. The OCN/PI/Vis system achieved a 93.9% removal of AO7 within 20 min and exhibited a reaction rate constant ( k = 1.48 × 10 −1 min −1 ) that was 4.4 times higher than that of the OCN/Vis system, significantly outperforming traditional oxidant-coupled systems (PMS/PDS/H 2 O 2 ). DFT calculations indicated that OCN exhibited an ultra-strong PI adsorption affinity ( E ads = −2.541 eV), leading to the elongation of the PI I-O bond and facilitating its activation. Quenching and electron paramagnetic resonance (EPR) experiments confirmed that singlet oxygen ( 1 O 2 ) is the dominant reactive species. Notably, the system demonstrated excellent anti-interference performance. This work establishes a high-efficiency, metal-free photo-Fenton-like system for dye wastewater treatment and provides a theoretical and experimental foundation for the rational design of g-C 3 N 4 -based PI activators, thereby opening new avenues for PI-based advanced oxidation processes (AOPs) in environmental remediation.
