The synthesis was conducted using lauroyl chloride and myristoyl chloride mixtures with molar ratios of 10:0, 9:1, 8:2, and 7:3 to investigate the effect of alkyl chain composition on interfacial properties. The obtained products, easily purified by phase separation, were characterized by Fourier transform infrared spectroscopy (FT–IR), proton nuclear magnetic resonance spectroscopy (1H NMR), and electrospray ionization mass spectrometry (ESI–MS). Surface tension, foaming ability, and foam stability were systematically evaluated. Surface tension measurements revealed comparable surface excess values for all compositions, while the critical micelle concentration showed a non-monotonic dependence on chain ratio, with a minimum at the 9:1 composition. Foaming tests demonstrated enhanced foamability and good foam stability for the mixed systems, particularly at the 9:1 ratio.

However, large-scale synthesis remains limited due to challenges in reproducibility, high solvent usage, and poorly understood reaction kinetics. This study investigates the coprecipitation method for synthesizing ZIF-67, aiming to develop a simple, cost-effective, and sustainable approach, emphasizing scalability and ease of production. This study systematically explores the effect of key reaction parameters such as impeller speed, molar ratio of precursors, reaction temperature, aging time, and solvent type on the morphology, particle size, and surface area of the synthesized ZIF-67 particles. To improve the process sustainability, the reuse of the mother liquor is also explored. A detailed kinetic analysis confirms that ZIF-67 synthesis is mass transfer–controlled, with a low activation energy (0.643 kJ/mol), highlighting the importance of effective mixing and reactor design. The optimized scale-up yielded ZIF-67 with a surface area of 1368.7 m2/g and consistent rhombic dodecahedral morphology, validating the scalability of the laboratory-developed process. Advanced characterization techniques, such as X-ray diffraction, scanning electron microscopy, particle size analysis, and Brunauer–Emmett–Teller surface area analysis, are employed to assess crystallinity, morphology, particle size distribution, and surface area, respectively. This study aims to bridge the gap between academic research and industrial-scale production by integrating chemical engineering principles into the synthesis of ZIF-67. The objective is to develop an optimized, reproducible synthesis protocol that can serve as a blueprint for scaling up other MOFs for real-world applications.","PeriodicalId":49237,"journal":{"name":"Asia-Pacific Journal of Chemical Engineering","volume":"21 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apj.70212","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148194115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose an innovative camphor–quartz sand composite architecture to construct a five-layer (camphor/quartz sand/YSZ/quartz sand/camphor) system, enabling thin yttrium-stabilized zirconia (YSZ) electrolyte films with double-sided rough surfaces for solid oxide cells (SOCs). Camphor is removed nondestructively via thermal sublimation, while quartz sand tunes surface roughness. The fabricated YSZ-M films exhibit average roughness (Ra) of 9.89 and 11.54 μm (vs. 0.24 and 0.39 μm for conventional YSZ-T films) with reduced thickness. At 850°C, YSZ-M-supported SOCs show superior performance: In SOFC mode, open-circuit voltage reaches 1.11 V and peak power density hits 0.58 W·cm−2 with lower ohmic and polarization resistance; in SOEC mode, CO2 electrolysis current density reaches 1.81 A·cm−2 (vs. 1.19 A·cm−2 for YSZ-T-based cells) with lower full-frequency impedance. This improvement stems from synergistic electrolyte thinning and double-sided roughening, promoting gas diffusion and ionic transport. Adaptable to multiple electrolytes and low-cost, this method supports large-scale electrolyte film production and SOCs commercialization.","PeriodicalId":49237,"journal":{"name":"Asia-Pacific Journal of Chemical Engineering","volume":"21 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apj.70223","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148194093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanoclays encapsulated in scaffolds protect and facilitate the long-term release of bioactive substances, such as growth factors, extracellular vesicles, and nucleic acids, thereby promoting tissue healing processes such as angiogenesis, osteogenesis, and stem cell recruitment and differentiation. Furthermore, recent developments in hydrogels, microspheres, and 3D-printed scaffolds containing nanoclays have emphasized their performance in preclinical models.

For the model characteristics, the NSGA-III algorithm is used to solve the problem. The reference points of the algorithm can be flexibly set according to the number of objectives, which allows for more efficient coverage of the high-dimensional objective space. The results show that the NSGA-III algorithm performs better in the solution performance, and the hypervolume (HV) indicator is improved by more than 10% compared with other algorithms. Comparison of the solution sets obtained using the NSGA-III algorithm with the existing literature shows that the optimization results on different objectives are improved by 4.6%–13.3%, and the comprehensive cost index is significantly reduced, which proves the effectiveness of the method.

Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents. Among the diverse range of adsorbents utilized for water applications, graphene-based materials are gaining substantial attention in the water treatment applications owing to their unique physicochemical properties. Clay minerals are also quite popular adsorbents due to their low cost, abundant availability, and environmental compatibility. In this respect, GO-intercalated bentonite (BNT) composite was developed via a facile solvent mixing method for the eradication of imidacloprid (IMD) pesticide from water. GO used in this study was fabricated from agricultural waste in order to increase the sustainability of the adsorption process. The synthesized adsorbent was further characterized via FTIR, BET, SEM, and TEM analysis. The experimental results showed that the addition of GO to BNT could improve the adsorptive removal of IMD in comparison to pristine BNT. The maximum removal of IMD using the fabricated composite was observed to be 92.83% under the optimized conditions (adsorbate concentration = 30 mg/L, adsorbent dose of 2 g/L, and 60-min interaction time). The Langmuir isotherm and pseudo-second-order kinetic models provided a reliable description of the experimental data. Further, the resulting composite satisfactorily adsorbed IMD from real water samples, indicating the applicability of fabricated adsorbents in real wastewater as well.","PeriodicalId":49237,"journal":{"name":"Asia-Pacific Journal of Chemical Engineering","volume":"21 3","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/apj.70226","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
