The impact of pulsed electric field (PEF) on the formation of acrylamide (AA) in air-fired French fries was investigated in this study. The results indicated that electric field intensity, pulse width, and cooking parameters significantly influence the formation of acrylamide in air-fried French fries. Compared with the traditional blanching treatment, PEF treatment more effectively inhibits AA formation and improves the cooking quality of French fries. Under optimal conditions, the AA content in the PEF-treated samples was reduced by 15.60% and 26.71% compared with that in the blanched and untreated groups, respectively. The significant suppression of AA formation may be closely associated with the ability of PEF to modify the microstructure of potato tissues and promote the leaching of AA precursors. PEF treatment did not induce significant gelatinization of potato starch. Instead, it caused electroporation of potato cells through polarization effects. This structural change enhanced heat and mass transfer efficiency during cooking, reduced processing time, and facilitated the continuous removal of key AA precursors, such as reducing sugars and asparagine. These structural and process modifications collectively suppress the Maillard reaction, thereby reducing AA generation. Furthermore, as a pretreatment method, PEF exhibits superior processing efficiency and lower energy consumption compared to blanching. In conclusion, PEF treatment can significantly decrease AA levels in air-fried French fries, showing great potential for producing healthier air-fried foods.

Amine-based CO 2 capture is a mature and commercially established technology. High-temperature regeneration causes amine thermal degradation, decreasing capture performance. The thermal stability of four long-chain triamines (N-C-C-C-N-C-C-C-N backbone) was evaluated and the inhibitors were screened. Degradation rates were monitored by gas chromatography and degradation products were characterized using ion chromatography and gas chromatography – mass spectrometry. Quantum chemical calculations and ReaxFF molecular dynamics simulations were employed to elucidate the degradation and inhibition mechanisms. The results indicate that triamines degrade rapidly via a radical-based mechanism. Formate and acetate were identified as the major anionic products, while low-molecular-weight fragments dominated the organic products. Under the tested conditions, the degraded solutions shows slight losses in CO 2 capture performance, but the performance losses were limited. Longer chains decrease the bond dissociation energy of C N and C C bonds and degradation is initiated by homolytic scission of C H and C N bonds, generating radical species and triggering subsequent radical reactions. The addition of 2-ethyl-4-methylimidazole enabled triamines to maintain a residual amine ratio of 80% even after thermal treatment at 423.15 K for 6 days by enhancing local electron density and forming stable non-covalent interactions with the triamines. This work provides insights for the development of high-stability amine-based solutions.

High-efficiency multistage solar interfacial evaporation requires covers that maximize solar spectrum transmission to the absorber while limiting thermal losses. Here, we establish a coupled numerical and experimental framework to tune the optical properties of transparent silica aerogels.We identify wavelengths < 500 nm as a critical, morphology-tunable scattering regime that also coincides with the AM 1.5G peak. Design maps suggest an optimal design in which a mean particle radius < 4 nm and a bulk density < 200 kg m −3 deliver total transmittance > 95% with haze < 5%. Further promotion in forward scattering can boost the transmittance even when haze is relatively high. Experimentally, guided by the multiscale model, we tuned the sol-gel process to reduce the silica aerogel mean scattering center radius from 4.9 to 3.1 nm, yielding a 5 mm-thick sample with a solar-weighted transmittance of 95.2%. Integrated as a greenhouse-selective cover in a 10-stage solar evaporation device, the optimized silica aerogel boosts the water production rate by 19.3%, from 5.22 to 6.23 kg m −2 h −1 , demonstrating that morphology tuning translates into system-level performance gains. These results provide actionable design rules and a validated predictive modeling framework for low-haze and high-transparency aerogel covers that enable efficient solar evaporation.

Thrombosis and inflammation, the primary causes of blood-contacting medical device failure, are initiated by interfacial biofouling. Although zwitterionic hydrogel coatings represent a promising solution, their clinical translation is hampered by the formidable challenge of simultaneously integrating mechanical robustness, high-strength substrate adhesion, and exceptional antifouling properties. Herein, we report a bioinspired zwitterionic hydrogel coating that overcomes this hurdle through a design combining microstructural alignment with multi-site chemical anchoring. The coating leverages cellulose nanocrystals (CNC) to induce an aligned microstructure that enhances antifouling through modulated interfacial hydrodynamics, while providing structural reinforcement for superior mechanical stability. An in situ multi-site chemical anchoring strategy is developed, enabling the coating to achieve an interfacial adhesion energy exceeding 800 J/m 2 on PVC substrates. Inspired by the vascular endothelium, the microstructure-aligned zwitterionic hydrogel coating significantly inhibits protein adsorption, platelet adhesion, and bacterial colonization. It retains outstanding stability even after 42 days of PBS shearing, 200 cycles of sandpaper abrasion, and 30 min of high-speed water flushing. Crucially, the coated PVC prevents biofilm formation and mitigates the foreign body response, while also inhibiting thrombus formation in an anticoagulant-free ex vivo rabbit circulatory model. This work lays the foundation for designing next-generation hemocompatible coatings for medical devices.

The insufficient understanding of the diffusion-reaction-polymerization coupling in membrane formation dynamics hinders the application of interfacial polymerization membranes in drug delivery and membrane separation. Here, the relationship between the hydrophilicity of the oil phase and water mass transfer behavior is taken as the breakthrough point. From the perspective of diffusion, the water mass transfer flux is positively correlated with the membrane thickness. From the perspective of polymerization, under the diffusion-limited aggregation model, the polymerization of oligomers leads to uneven membrane thickening. This accounts for the paradoxical observation that thicker membranes exhibit lower encapsulation and rejection rates. Building on a comprehensive understanding of membrane formation dynamics, an AI model that can predict performance with high precision was developed. Furthermore, universal regulation strategies can increase the encapsulation efficiency and rejection rate by 32.3–54.8% and 6.8–23.9%, respectively. This study provides both theoretical basis and technical approaches for designing high-performance microcapsule and separation membrane.

In photocatalytic hydrogenation, non-directional transfer of electrons and indiscriminate oxidation of products by holes often result in severe electron–hole recombination and unintended product degradation, limiting overall efficiency. Herein, we engineer both the substrate reduction and product oxidation pathways through an interface–pore co-confinement strategy, exemplified by a rationally designed covalent organic framework (COF)-bridged core–shell photocatalyst (U@TpBpy-Rh) and photocatalytic NADH synthesis. The resultant U@TpBpy-Rh functions through dual mechanisms: (1) the confined S-scheme heterojunction interface facilitates directional electron transfer from MOF core to Rh sites in COF, significantly enhancing the photocatalytic NADH synthesis with productivity of 2.82 mmol g −1 h −1 ; (2) the confined pores of the COF shell restrict NADH diffusion toward highly oxidative MOF regions, reducing its oxidation degradation by 63% compared to U@TpBpy. This work demonstrates simultaneous spatiotemporal management of competitive photocatalytic reduction and oxidation pathways and will offer a general strategy for optimizing other redox-coupled reactions.

Here, MCM-22 zeolites were synthesized by a hydrothermal synthesis method using a mother liquor recycling procedure, in which the use of organic templates was greatly reduced with a molar ratio of template to SiO 2 at 0.15 in the zeolite gel precursors. The as-prepared MCM-22 zeolites show high crystallinity and flake-like morphology with a thickness below 100 nm, possessing a high specific surface area of approximately 470 m 2 /g and substantial mesoporous volume of 0.49 cm 3 /g. The oxalic acid treatment was applied to adjust the textural properties of MCM-22 zeolite as well as the acid sites concentration from 0.43 to 0.22 mmol/g. The selective extraction of extra-framework aluminum via oxalic acid treatment leads to an increase in the ratio of Brønsted acid site amount to Lewis acid site amount (B/L ratio) from 0.59 to 1. The as-modified MCM-22 zeolite shows an enhanced propylene selectivity (44.7%) relative to the MCM-22 zeolite (35.6%). The eco-friendly synthesis strategy combined with an effective acid modification method is anticipated to expand the application of MCM-22 zeolite for designing high-performance catalysts for methanol to olefins (MTO) reaction. Graphical This work offers an eco-friendly route for the synthesis of MCM-22 zeolite via a mother liquor recycling strategy. Oxalic acid treatment enables precise control of acid sites by removing extra-framework Al, thereby suppressing the aromatic-based cycle in the MTO reaction and yielding high selectivity toward target olefins (e.g., propylene).

Due to lower energy consumption, great separation performance, and simple operation process, membrane technology plays an important role in gas separation. However, separation membranes often face a trade-off between permeance and selectivity. For instance, the pure layered double hydroxide (LDH) or metal organic framework (MOF) membranes exhibit high gas permeance but suffer from low selectivity. However, conventional Pd membranes typically have a thickness exceeding 50 μm, resulting in high costs and limited permeance. This article develops a novel strategy to fabricate a CoAl LDH/zeolitic imidazolate framework (ZIF)-67 heterostructure on a polydopamine-modified substrate, following by the infiltration of Pd nanoparticles (Pd NPs) into the LDH/ZIF framework via magnetron sputtering, resulting in a well-integrated LDH/ZIF@Pd membrane for highly efficient H 2 /CH 4 separation. In this architecture, the LDH sheets not only create nanocorridors for gas permeation but also provide the nucleation sites for ZIF grains. The incorporated Pd NPs and LDH/ZIF network form a well-integrated heterostructure, which endows the LDH/ZIF@Pd hybrid membrane with exceptional comprehensive performance, achieving H 2 /CH 4 selectivity of 48.3 and ultrahigh H 2 permeance of 8.4 10 5 GPU (75°C, 1 bar). This result sets a new benchmark for membrane-based gas separation, demonstrating outstanding potential for advanced hydrogen purification and sustainable energy applications. Graphical A novel layered double hydroxide (LDH)/zeolitic imidazolate framework (ZIF)@Pd hybrid membrane is developed for H 2 /CH 4 separation by constructing LDH/ZIF heterostructure and infiltrating Pd nanoisland, which demonstrates a remarkable combination of excellent H 2 /CH 4 selectivity of 48.3 and ultrahigh H 2 permeance exceeding 8.4 10 5 GPU, achieving an order of magnitude improvement in separation performance, showing great potential for hydrogen purification and sustainable energy applications.

Marine biofouling adversely affects the operational performance of marine infrastructure. A promising solution to this challenge involves fabricating PET fibers with inherent antifouling properties via chemical bonding. Inspired by the design concept that zwitterionic structures can form highly ordered hydration layers via electrostatic interactions, thereby reducing foulant adhesion, this study proposes a strategy for developing marine antifouling PET fibers. By grafting primary amine-terminated sulfobetaine onto PET fibers, grafted fibers with antifouling capabilities were obtained. Laser scanning confocal microscopy was used to examine the adhesion of algae and proteins on the fiber surfaces. The results demonstrated that the grafted fibers exhibited significant resistance to algal and protein attachment, along with effective antibacterial activity against Escherichia coli and Staphylococcus aureus . Furthermore, colorimetric crystal violet assays confirmed the inhibitory effect of the grafted fibers on biofilm formation. The development of this novel antifouling PET fibers offer a potential approach to addressing biofouling issues in deep-sea aquaculture cages. Highlights PET fibers are dopamine-treated to add reactive surface sites. Sulfated betaine was grafted onto fibers via its N-terminal amine. Grafted fibers resist adhesion by bacteria, proteins, and algae.

The viscosity and elasticity of water-soluble polymers are critical in the petroleum industry, particularly under high-temperature and high-salinity conditions. In this study, a multi-armed hydrazide-POSS (HPOSS) and a carbonyl-functionalized hydrophobic association polymer (CFHAP) were developed to create dual networks (CFHAP/HPOSS). Unlike conventional binary cross-linkers, HPOSS promoted the formation of dense and stable covalent cross-linked structures. Even at low concentrations of both CFHAP and HPOSS, CFHAP/HPOSS exhibited robust network formation with exceptional thickening properties, achieving a significantly higher viscosity of 3927 mPa·s at 2 g/L compared to the polymer's 410 mPa s and the binary cross-linking system's 2453 mPa s. Under a 40 g/L Na + solution, CFHAP/HPOSS exhibited salt responsiveness by enhancing their hydrophobic network, resulting in a viscosity of 5325 mPa s and a modulus G′ > G″. These enhanced rheological properties were further utilized to improve aqueous foam stability. The results revealed improved foam stability with an extended half-life time (8248 s), low drainage rate (0.0064 g/s maximum), and minimal bubble size distribution variation. SEM images also reveal a fully formed polymer film network, which effectively inhibits foam drainage and coarsening. Our strategy provides valuable insights into developing new materials with adjustable thickening and elastic properties. Highlights A multi-armed hydrazide-POSS is synthesized and used as a crosslinking agent. Dynamic acylhydrazone bond is used to fabricate a network with enough stability. Hydrophobic interaction is used to fabricate a network with salt responsiveness. The prepared polymer exhibits improved viscosity and elasticity.

Port-wine stain (PWS) is a congenital capillary malformation in which ecstatic venules reside several millimeters beneath the epidermis, limiting the effectiveness of visible-light therapies that suffer from shallow penetration and significant photothermal deposition. To address these challenges, we engineered a UCNP@HMME nanoplatform that transduces near-infrared (NIR) light into visible emission to activate the photosensitizer hematoporphyrin monomethyl ether (HMME) at depth. In a vascular-rich chicken wattle model of PWS, we compared the therapeutic effect of UCNP@HMME-mediated NIR-PDT with visible-light-activated HMME-PDT. UCNP@HMME with 980 nm irradiation produced immediate purpura, progressive bleaching, and significant reductions in dermal capillaries with sustained antivascular effects. In contrast, 532 nm HMME-PDT achieved strong superficial bleaching but induced blistering and ulceration. Thermal profiling showed that 532 nm irradiation elevated blood temperature, whereas 980 nm irradiation did not measurably increase temperature, mitigating nonspecific thermal injury. These findings demonstrate that UCNP-mediated NIR activation decouples photochemical efficacy from epidermal heating, enabling deeper, safer, and more durable vascular photoablation in a PWS model.

Lignin, a crucial renewable biomass component, represents a high-value pathway for achieving efficient biomass utilization. However, its complex and stable structure hinders the development of effective lignin depolymerization catalysts. In this study, the water-soluble H3PMo12O40 was combined with [Bmim]+ to form hydrophobic [Bmim]3PMo, which was supported on ZrO2 at various weight ratios to prepare [Bmim]3PMo@ZrO2 catalysts. These catalysts demonstrate excellent activity in lignin oxidative depolymerization, selectively producing monomeric phenolics (methyl vanillate, vanillin, methyl syringate, syringaldehyde). The 40 wt % [Bmim]3PMo@ZrO2 catalyst achieves optimal performance with 88.5% lignin conversion and 12.4 wt % phenolic yield. Two-dimensional nuclear magnetic resonance heteronuclear single quantum coherence (2D HSQC NMR) analysis confirms that the catalyst effectively cleaves the critical β–O–4 linkages in lignin. Furthermore, [Bmim]3PMo@ZrO2 has excellent reusability with stable performance over five cycles. These findings establish [Bmim]3PMo@ZrO2 as a promising lignin valorization candidate, inspiring efficient catalyst design for producing high-value aromatic compounds.
