Additionally, the role of biochar in mediating coupled methane (CH₄) oxidation and H₂S removal within biofiltration systems warrants further investigation. To address these gaps, three stimulated landfill soil covers with biochar amendment were constructed (50 cm depth) and fed with 50 % CH₄, 50 % CH₄ + 500 ppm H₂S, and 500 ppm H₂S, respectively. Over 253 days, changes in gas removal efficiencies, soil properties, microbial community composition, and functional genes were tracked. The differentiation among treatments was primarily observed in the topsoil. Fresh biochar effectively alleviated the inhibition of methanotrophic activities by adsorbing H₂S, thereby maintaining high CH₄ removal efficiencies initially. However, as biochar reached adsorption saturation and microbial H₂S metabolism intensified, CH₄ removal efficiency was significantly reduced. Over time, the microbial composition and metabolism of the biofiltration system shifted from dominance by <em>Methylocystis</em> (type II) to dominance by <em>Methylocaldum</em> (type I), driven by H₂S selection and microbial interplay-governed deterministic processes. In the final stages, increases in pH and total organic carbon, facilitated by biochar, enhanced the role of stochastic processes, which sustained the equilibrium of the altered methanotroph composition. These changes ultimately restored CH₄ removal efficiencies to above 70 %. This study demonstrates the natural resilience of CH₄ biofiltration systems with biochar as a stimulant and provides new insights into the microbial assembly processes driving successional changes in biofiltration performance.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"15 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanoadsorbents possess high adsorption capacity but complex solid–liquid separation procedures. It is an unresolved challenge to design an adsorbent with both capabilities. Here, we covalently linked metal–organic frameworks (MOFs) and ethylene imine polymer (PEI) to chitosan hydrogel beads (3 mm). Assists with the ice template method to construct a multistage pore network structure of aerogel beads (CTS-U-E) for purifying Cr(VI) wastewater. The rich multistage pore network and high specific surface area of CTS-U-E (130.91 m² g⁻¹) enable fast adsorption kinetics and excellent selectivity. Its maximum adsorption capacity of 471.5 mg g⁻¹ is 2.47 times greater than that of commercial adsorbents and exceeds most reported nanoadsorbents. Impressively, after six cycles of adsorption tests, the Cr(VI) removal rate of CTS-U-E still reached 79 %. CTS-U-E is considerably more cost-effective than commercial activated carbon and resin, owing to its inexpensive raw materials and superior recycling capabilities. Density functional theory reveals that the strong affinity of N, O, and methylene for Cr(VI) results in their role as natural anchor points for efficient Cr(VI) adsorption. The reaction of Cr(VI) with amines to form highly active intermediates may further lead to ultra-high Cr(VI) removal. This study inspires a promising route for developing high-adsorption materials for Cr(VI) wastewater treatment and offers new insights into adsorption mechanisms.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"27 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was achieved by incorporating a low dose of chiral ligand R-NEA ((R)-(+)-1-(1-naphthyl) ethylamine) to substitute for HAD locally.

Our investigation reveals that the rigid chiral ligand R-NEA partially replaces the flexible straight-chain HDA, inducing a local symmetry-breaking distortion of an inorganic framework in R-HDASnBr₄, which in turn stimulates robust CPL activity in R-HDASnBr₄. This strategy can also flexibly bind to other tin-based DJ perovskites, demonstrating its generality for chiral transfer.

Thus, we enhanced the pseudocapacitive contributions and the ion/charge transfer kinetics through nano-interfaces. These hybrid structures were formed through the layer-by-layer self-assembly of two-dimensional nanosheets. This design facilitates the construction of low-dimensional nanoarchitecture suitable for long-term cycling without ionic intermediates.

However, the establishment of rapid and efficient PN is always challenging. In this study, we investigated the effects of inhibition under cold storage on the activity of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in activated sludge, as well as on the overall performance of the system during the establishment of PN. The control group R1 was set up using traditional control methods such as low dissolved oxygen (DO) concentration and intermittent aeration. In addition to the same control conditions as R1, R2 established PN more quickly after the inhibition under cold storage. R2 showed the effect of nitrous accumulation at day 25, whereas R1 showed nitrous accumulation until day 55. The nitrite accumulation rate (NAR) of R2 had reached 96.52% at day 77, whereas the NAR of R1 was higher than 90% until day 89. In addition, the gap between AOB and NOB activities was widened earlier within R2 compared to R1. High-throughput results showed that the abundance of AOB in inoculated sludge and final R1 and R2 was 0.03%, 5.50% and 19.01%, respectively, and the abundance of NOB was 1.84%, 0% and 0.05%, respectively. It can be seen that the strategy of inhibition under cold storage is helpful to accelerate the realization of PN and maintain a high abundance of AOB. This study provides a new strategy for the rapid establishment and stable operation of PN.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"20 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Covalent triazine frameworks (CTFs) are promising photocatalysts for solar-driven H₂O₂ generation due to their tunable structures. However, the catalytic mechanism is not fully understood, and efficiency remains limited, making it a significant challenge to extend their application to practical H₂O₂ production. To address this, inspired by the role of dihydrophenazine (DHPZ) as an electron transfer carrier in biochemical reactions, we introduce a dihydrophenazine (DHPZ)-functionalized CTF (TA<strong>–</strong>DHPZ) designed to facilitate effective electron transfer, leveraging DHPZ’s redox cycling to promote the reduction of O₂ to H₂O₂. The DHPZ unit in TA<strong>–</strong>DHPZ sequentially oxidizes to phenazyl radical (PZ^•+) and phenazinium salt (PZ²⁺) during H₂O₂ synthesis, then photoreduces back to DHPZ, maintaining continuous electron flow and lowering the energy barrier. As a result, TA<strong>–</strong>DHPZ achieves a remarkable H₂O₂ production rate of 7787 μmol g⁻¹h⁻¹, outperforming its molecular counterpart TA<strong>–</strong>AN (anthracene-functionalized CTF), by capitalizing on DHPZ’s redox efficiency.

First, a virtual representation of the carbon-paper based gas diffusion layer (GDL) is reconstructed combining computer-aided design with advanced image processing techniques. Next, a rigorous validation of the stochastic geometry in terms of its morphological and transport properties is carried out using benchmark experimental data for commercially available GDL material. Once validated, three-dimensional (3D) transport based diffusion and electronic/thermal conduction simulations are carried out to study the dependence of the GDL effective properties on the geometrical meso-scale parameters such as fiber diameter, binder volume fraction, fiber density per layer. The presented analysis shows that the effect of the variation of these individual parameters are equivalent as long as the bulk porosity of the geometry is kept constant, thus validating the usability of two-parameter based porosity-tortuosity based correlations for the GDL. As the final step, the simulation data are used to develop accurate structure–property correlations for the GDL. The developed correlations provide more realistic estimates of the GDL effective properties, compared to their semi-empirical counterparts such as Bruggeman correlation. This improvement is attributed to the retention of the information regarding the underlying true tortuosity and non-isotropic, non-spherical pore space, in the functional forms of the developed correlations. The refined correlations in this work can be applied to improve the prediction accuracy of computationally lean lumped-parameter GDE-based electrolyzer models.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"36 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the strong electronegativity and high surface charge density in the fluorine environment of process manufacturing tend to result in its poor corrosion resistance performance. Addressing the brittle behavior of fluorides due to strong ionic bonding and the corrosion attack mechanism triggered by the special electronic structure properties of fluoride ions remains a challenge. Studies have indicated that rare earth yttrium (Y) can enhance the fluorine corrosion resistance of ceramic coatings by modifying the fluoride passivation layer structure. In this work, we demonstrate a new strategy for developing high-quality yttrium assisted fluorine corrosion resistant novel coating in situ on aluminum alloy (6061) by two-step micro-arc oxidation (MAO) process. The coatings maintain sustainable corrosion protection and excellent wear resistance performance after 28 days immersion in 0.1 mol/L NaF solution. The results show that the loading of yttrium leads to effectively mitigating the fatal microcracks on the surface by inhibiting the growth of oxygen vacancies in the coatings, and promotes the formation of small sized structures. The stronger and more robust Al-O covalent network structure provides better physical barrier effect and reduces the strong penetration intrusion of small radius fluoride ions. Density-functional theory (DFT) calculations show that matching affinity kosmotrope fluoride ions on the atomic level significantly reduce the adsorption effect on the coating surface. Moreover, yttrium can improve the interfacial dislocation effect of low fracture toughness fluoride reaction film, and effectively inhibit the crack extension of corrosion products as well as promote the stability of corrosion interfacial interaction.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"22 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
