A waxberry-like gradient porous aerogel/honeycomb metamaterial (WGPA/H) was fabricated by an innovative dot-matrix cold-source ice-templating technique. • WGPA/H achieves a remarkable RL min of −78.5 dB and an ultrabroad EAB of 12.4 GHz. • WGPA/H maintains robust EMWA performance under oblique incidence angles ranging from 5° to 60°. • WGPA/H exhibits excellent load-bearing capacity and thermostability. Porous aerogels have emerged as promising candidates for lightweight electromagnetic wave absorption (EMWA) materials, yet their practical performance and engineering deployment are severely constrained by three long-standing bottlenecks: the inherent trade-off between interfacial impedance matching and internal electromagnetic dissipation, the strong angular dependence of EMWA performance, and the insufficient mechanical load-bearing capability. Herein, we developed a novel dot-matrix cold-source ice-templating technique in conjunction with honeycomb skeleton reinforcement to fabricate waxberry-like gradient porous aerogel/honeycomb metamaterials (WGPA/H). The influences of critical structural parameters, including aerogel pore structure and honeycomb cell size, were systematically investigated. The optimal WGPA/H delivers an exceptional minimum reflection loss (RL min ) of −78.5 dB and an ultrabroad effective absorption bandwidth (EAB) of 12.4 GHz. More notably, WGPA/H retains a stable ultrabroad EAB at oblique incidence angles from 5° to 60°, demonstrating excellent angle-insensitive EMWA behavior. This outstanding comprehensive EMWA performance is attributed to the synergistic coupling effect between the unique waxberry-like gradient porous structure and the periodic honeycomb array. Furthermore, WGPA/H integrates high thermostability and a compressive strength up to 4.1 MPa, fully satisfying the service requirements of complex high-temperature and high-loading scenarios. The resultant WGPA/H well preserves the intrinsic lightweight characteristic of aerogels, breaks the trade-off between impedance matching and electromagnetic loss, realizes wide-angle EMWA stability, and simultaneously achieves significantly enhanced mechanical load-bearing performance. This work provides a new structural design strategy for multifunctional EMWA devices, facilitating their practical engineering applications.

One-step MXene/CNTs-COOH/CS/IL sensing interface was constructed. • CNTs-COOH alleviated MXene restacking and promoted electron transport. • CS and ionic liquid enhanced metal-ion enrichment and ionic transport. • The sensor simultaneously determined Cd 2+ , Pb 2+ , Cu 2+ , and Hg 2+ . • Real-water results agreed well with ICP-MS measurements. Rationally coordinating ion accessibility, electron transport, metal-ion enrichment, and film stability within a facile electrode architecture remains challenging for multiplex electrochemical analysis. Herein, an MXene-based multicomponent sensing interface was constructed through the one-step integration of carboxylated carbon nanotubes (CNTs-COOH), chitosan (CS), and an ionic liquid (IL) with Ti 3 C 2 T x nanosheets. CNTs-COOH act as conductive nano-spacers that alleviate MXene restacking and improve electronic connectivity, while CS provides coordination-active amino and hydroxyl groups for metal-ion enrichment and contributes to film stability. The incorporation of IL improves component dispersion and ionic transport and partially mitigates the interfacial transport limitation associated with the CS-containing layer. Structural and electrochemical characterization results collectively support complementary roles of the four components in regulating interfacial accessibility, analyte accumulation, and charge-transfer behavior. Under the optimized conditions, the resulting electrode enabled the simultaneous determination of Cd 2+ , Pb 2+ , Cu 2+ , and Hg 2+ by differential pulse anodic stripping voltammetry over linear ranges of 0.5–22.5, 0.5–60, 0.5–87, and 0.5–62 μM, respectively. The corresponding detection limits were 0.1539, 0.0746, 0.2279, and 0.0931 μM. The sensor also exhibited satisfactory selectivity, reproducibility, and long-term stability, retaining approximately 92–95% of its initial response after 30 days. Recoveries of 92.2–96.0% were obtained in spiked tap-water and river-water samples, and the measured concentrations were consistent with those obtained by ICP-MS. These results demonstrate a functionally coordinated interface-engineering strategy for the simultaneous electrochemical determination of multiple heavy metal ions.

Photocatalytic upcycling of polylactic acid (PLA) via a two-step process-hydrothermal depolymerization to a lactic acid (LA)-rich hydrolysate followed by selective photocatalytic oxidation to form value-added chemicals-presents a sustainable pathway for plastic waste upgrading. However, the efficient activation of LA molecules and effective generation of key intermediates remain significant challenges. Herein, Pd nanoparticle-modified ZnIn 2 S 4 (Pd-ZIS) nanosheets were developed to promote selective conversion of PLA hydrolysate to acetic acid (AA). In situ FTIR spectral analysis indicates that Pd nanoparticles promote electron transfer and O 2 dissociation, accelerating the generation of hydroxyl radicals via proton-coupled electron transfer (PCET). Furthermore, in situ electron paramagnetic resonance (EPR) results reveal that Pd nanoparticles effectively activate the C α ─C COOH bond in LA molecules, promoting the formation of acetyl radical intermediates that subsequently couple with hydroxyl radicals to yield AA. Consequently, the optimized 0.5 wt% Pd-ZIS catalyst exhibits superior performance, achieving an AA production rate of 4.2 mmol g −1 h −1 with a selectivity of 88.7% and an apparent quantum yield of 1.31% ( λ = 380 nm). These performance metrics surpass those reported in most previous studies. This work offers novel insights into catalyst design for waste plastic upcycling, deepening the understanding of the mechanisms to effectively regulate the underlying complex reaction pathways.

Oxidative polymerization is an unrecognized yet critical pathway in CH 3 CO 3 • -mediated AOPs. • Polymerization contributes ∼20–65% to phenolics removal depending on substituent merits. • CH 3 CO 3 • -driven polymerization process works efficiently in saline and real coking wastewater. • Recovered polymers can be valorized as functional porous carbon materials with high surface area. The acetylperoxyl radical (CH 3 CO 3 • )-based advanced oxidation processes (AOPs) have been widely employed for organic contaminant elimination, with existing studies predominantly attributing pollutant removal to mineralization or fragmentation pathways. However, the contribution of oxidative polymerization triggered by CH 3 CO 3 • has been systematically overlooked. Herein, by taking the widely-studied CH 3 CO 3 • -based oxidation system (i.e., Co 2+ /PAA), we demonstrated that oxidative polymerization constitutes a critical pathway, accounting for 12.2–61.4% of phenolic contaminants removal in CH 3 CO 3 • -driven AOPs depending on the substituent merits. Through systematic analysis of the transformation of phenol during the oxidation and comprehensive characterization of recovered solid polymers, we confirmed the formation of solid-state polymers in the Co 2+ /PAA system. Thermodynamic calculations further validate the feasibility of polymerization mechanisms, identifying hydrogen abstraction (HAA) as the predominant initiation step. Notably, this oxidative polymerization phenomenon persists in complex aqueous matrices and real coking wastewater systems, demonstrating environmental relevance. Importantly, the harvested polymeric solids exhibit potential for valorization as precursor materials for porous carbon synthesis, achieving surface areas as high as 635.7 m 2 /g with promising catalytic performance. This work uncovers a previously neglected but significant polymerization pathway in the CH 3 CO 3 • -based AOPs, establishing a sustainable avenue for phenolic wastewater purification. Oxidative polymerization, which has been largely overlooked in CH 3 CO 3 • -mediated AOPs, constitutes a critical route for removing electron-rich phenolic compounds, accounting for ∼20–65% of contaminant elimination depending on substituent characteristics. The CH 3 CO 3 • -driven polymerization process proves effective for treating phenolic industrial wastewater. It enables simultaneous phenolic contaminant removal and the recovery of solid polymer products, which can be further valorized as precursors for porous functional carbon materials.

BACKGROUND Reducing dietary fat intake has become a prevalent health pursuit. In this study walnut meal protein (WP) with a protein content of 90.43% was utilized as a fat mimetic to optimize formulation, investigate component interaction mechanisms, and assess the storage quality of low-fat ice cream. RESULTS Sensory evaluation and melting rate were used as indicators. The optimal processing conditions were determined to be a cream-to-WP ratio of 21:7, skimmed milk powder addition of 4.30%, and guar gum (GG) addition of 0.06%. Compared to the control sample, the WP and GG samples showed that the WP-GG mix exhibited a smaller particle size, higher absolute zeta potential and viscosity, and lower surface tension. This suggests that the WP and GG mix can synergistically form a stable protein–polysaccharide composite gel network. Laser scanning confocal microscopy images confirmed that the WP-GG sample mix exhibited a markedly dense and homogeneous structure. After 6 weeks of frozen storage, the WP-GG sample demonstrated the highest overrun, the lowest melting rate, and the lowest hardness. At week 6, the syneresis rate was 70.42 ± 0.65% ( P < 0.05), indicating the best freeze–thaw stability. Furthermore, short-term storage test results showed that on day 9 the peroxide value and acid value of the WP-GG sample were only 1.48 ± 0.09 mmol kg −1 and 1.92 ± 0.07 mg g −1 , respectively. This confirmed that the steric hindrance between WP and GG maximally delayed lipid oxidation, effectively maintaining the oxidative and flavor stability of the ice cream. CONCLUSION This research provides a theoretical basis for the high-value utilization of WP and the development of low-fat ice cream. © 2026 Society of Chemical Industry.

Evolution of active sites is a common fact, which originates from entropy gains or enthalpy losses that effectively regulates the selectivities and rates during catalysis, however, is very difficult to probe. In this work, a PdCu organic precursor was synthesized and dispersed well on SiO 2 support by impregnation method (c.a. Pd 1 Cu 1 /SiO 2 ). Within the initial stage of phenylacetylene hydrogenation, Pd 1 Cu 1 /SiO 2 showed severe overhydrogenation. Consequently, Pd species were carburized to PdCuC x ensembles and facilitated the styrene formation significantly (>99% conv., >98% selec.). Interestingly, the activation process was highly dependent on the type and concentration of the reactant gas, in which the increase of alkyne concentration promoted the evolution of active sites (i.e. carbonization of Pd) and improved styrene formation, whereas the promotion of hydrogen stabilized palladium hydride and hindered carbonization process, which led to the overhydrogenation. These findings were well evidenced by catalytic performance evaluation and relative characterizations, i.e. quasi-in situ XPS and HRTEM etc. Clearly, the dynamics of PdCuC x ensemble generation were significantly correlated to the concentrations of the alkyne and hydrogen, which could modify the selective hydrogenation behaviour greatly.

The separation of benzene/cyclohexane (BZ/CHX) represents a critical yet challenging task in the chemical industry, as their nearly identical boiling points and kinetic diameters render conventional distillation highly energy-intensive. Pervaporation, driven by a transmembrane pressure difference, offers an energy-efficient alternative by breaking the azeotropic equilibrium of BZ/CHX mixtures. Metal–organic framework (MOF) membranes have emerged as promising candidates for such separations owing to their exceptional structural tunability. However, their application in this context remains largely unexplored. Herein, we report a dual-ligand engineering strategy to fabricate UiO-66-CDC MOF membranes, wherein a cubic alkane ligand is incorporated into a planar parent ligand to create a dual-ligand-modified framework. This approach enables precise regulation of the pore microenvironment and enhances preferential adsorption and recognition of aromatic benzene over aliphatic cyclohexane through multiple interactions (C···C, H···C, C–H···π, C–H···O, and π···π). Consequently, under a single-stage operation with an equimolar (50:50) BZ/CHX feed, the optimized membrane delivered a permeation flux of 478 g m −2 h −1 and a separation factor of 5.8, corresponding to a 40% increase in flux and an 81% increase in separation factor, respectively, over the control membrane, and yielding a 110% higher PSI. When further applied to a two-stage membrane separation process, the total flux and separation factor reached 1747 g m −2 h −1 and 40.7, respectively, demonstrating the potential of process intensification. This dual-ligand design offers fundamental guidance for the development of advanced separation membranes targeting diverse aromatic/alkane mixtures.

Dark beer melanoidin (BM) exhibited colloidal properties and negative charge. • Glycosidic, peptide and non-covalent bonds were broken after chemical treatment. • Structure and bioactivity of BM were relatively stable during in vitro digestion. • The levels of polyphenolics and SCFAs were increased during colonic fermentation. • Phloroglucinol was the main phenolic compound during colonic fermentation. Melanoidins are brown macromolecular products of Maillard reaction formed through thermal processing, which provide unique flavor and bioactive function of food. This study aims to reveal the changes of structure and bioactive characteristics in beer melanoidin-rich fraction (BM) during different chemical treatments and in vitro digestion and fermentation. The results showed that BM had colloidal properties with 24.21–99.28 nm and negative charge, which mainly contained carbohydrates. In addition, microscopic morphology showed surface cracks after acid treatment, blocky particles after alkali treatment, and some porous small particles after salt treatment. These might be caused by the disruption of polysaccharide, protein, and the skeleton structure through spectra. Moreover, during simulated in vitro digestion stage, Mw of BM was slightly decreased, which might be due to the breakage of glycosidic bonds. Microscopic morphology presented a relatively complete block structure. However, the contents of total phenolics and flavonoids and the production of short-chain fatty acids were significantly increased during colonic fermentation process. Phloroglucinol was the main phenolic compound and its content also increased during colonic fermentation. Collectively, the results indicated that BM had relative stability during the digestion stage, and released bioactive compounds during colonic fermentation. These findings suggest that BM, as a novel colloidal prebiotic, possesses potential role in intestinal health. Download: Download high-res image (164KB) Download: Download full-size image

The clinical utility of epirubicin (EPI) is limited by its rapid clearance, insufficient tumor accumulation, and severe systemic toxicity. Although albumin-based nanocarriers offer a potential solution, their development is hindered by the inherently weak affinity between EPI and albumin. Here, we reported an affinity-driven prodrug-albumin nanoassembly via a modular design. Specifically, EPI was conjugated to myristic acid (C14) via a pH-sensitive hydrazone linkage to form EPI-C14, which co-assembled with bovine serum albumin (BSA) into stable nanoassemblies (EPI-C14@BSA NPs) with high drug loading and binding efficiency at an optimized ratio. Fatty acid modification markedly enhanced drug-albumin affinity, leading to improved pharmacokinetics compared with free EPI. Upon reaching the tumor site, EPI-C14@BSA NPs responsively released EPI in the acidic microenvironment, inducing potent cytotoxic effects. Benefiting from improved systemic exposure and tumor-selective drug activation, EPI-C14@BSA NPs exhibited superior antitumor efficacy in a 4T1 tumor-bearing mouse model at a high dose, while effectively mitigating body weight loss and systemic toxicity associated with free EPI, thereby achieving a favorable balance between efficacy and safety. This work presented a rational prodrug strategy to enhance drug-carrier affinity, offering a promising approach to expand the utility of albumin-based nanoplatforms for chemotherapy.

Polyphenylene sulfide (PPS) fiber, as a high-performance material, exhibits exceptional heat resistance, chemical stability, and mechanical properties, making it widely used in environmental protection, chemical filtration, and military applications. However, its poor dyeability limits its application in textiles. In this study, PPS fibers were subjected to electron beam (EB) irradiation at various absorbed doses and subsequently evaluated for their dyeing performance with disperse dyes. The results demonstrated that EB irradiation improved dyeability by altering the surface structure of PPS fibers. At an irradiation dose of 120 kGy, the fiber surface became rougher, the crystallinity decreased significantly from 25.89% to 11.68%, and the water contact angle decreased from 141° to 111°. Dyeing performance tests indicated that the color strength increased from 2.5 to 9.6 and the dye uptake increased from 18% to 77%.

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.

Shape-stabilized phase change materials (SSPCMs) are promising for thermally functional mortars, but slight leakage during mixing and phase transition can degrade the particle–matrix interface and reduce durability. This study developed a surfactant-free interfacial self-assembly route to build a hydrophobic silica shell on diatomite/ n -hexadecane SSPCM particles. The shell increased the particle contact angle from 112.1° to 140.2° and reduced leakage to 0.12% after 4 h at 60 °C. At equal PCM dosage, the shell-modified mortar showed lower water absorption and chloride diffusion and higher compressive strength than mortar with unmodified SSPCM. After 500 thermal cycles between 0 and 40 °C, the shell-modified mortar retained a melting enthalpy of 8.85 J/g with only 1.8% latent-heat loss. Microscopy and nanoindentation indicated a denser interfacial region, showing that a simple mineral shell can improve thermal-storage mortar reliability for building applications.
