The reaction is highly exothermic and, under inadequate control, may cause thermal runaway and lead to catalyst deactivation. Therefore, thermal regulation is crucial for ensuring optimum productivity. Microencapsulated phase change materials (MEPCM) were introduced as a promising thermal regulation approach because of their superior capability in controlling the system temperature using the latent heat storage (LHS) concept. This study aims to improve the effectiveness of MEPCM as catalysts support by incorporating mass transfer agent for CO₂ methanation process, building upon prior research which focuses on direct impregnation on MEPCM support. To accomplish this goal, a novel MEPCM catalyst structure was developed by loading a Ni metal active site onto the ZrO₂-CaO surface-enhanced MEPCM. Novel MEPCM catalysts were prepared using three sequential methods: MEPCM synthesis, surface modification, and catalyst impregnation. Characterization analysis revealed that the modification improved the surface area by 45%. ZrO₂-CaO doping successfully enhanced the catalytic performance by increasing the CO₂ conversion and CH₄ selectivity by 8 and 6%, respectively. In addition, the LHS function of the catalyst-loaded MEPCM suppressed the rapid increase in temperature during the initiation of CO₂ methanation. Further development of this concept is expected to enhance the efficiency of runway reaction control across numerous chemical industries.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"105 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020066","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}

Organic cocrystal engineering has gained prominence as a versatile method to improve pesticide properties, characterized by ease of preparation, proven effectiveness, low cost, and scalability. In this work, we report an organic ionic cocrystal of 2,4-D with DL-proline, where both molecules self-assemble through hydrogen bonding in the crystal lattice, with DL-proline maintaining its zwitterionic form. Compared to pure 2,4-D, the cocrystal reduces volatility by over 70 % while exhibiting excellent stability at room temperature. Furthermore, the cocrystal enhances the release profile of the active compound across a range of temperatures (15 °C, 25 °C, 35 °C), with a solubility increase of more than 2.8-fold. Moreover, the cocrystal reduces the evaporation rate of the solution, leading to a longer retention time on leaf surfaces. In terms of herbicidal efficacy, the cocrystal provides equivalent weed control at just 1/4 of the dosage required for pure 2,4-D. Additionally, it exhibits reduced toxicity to zebrafish and human hepatocytes and cardiomyocytes. This work underscores the significant potential of organic cocrystal engineering in improving multiple herbicide properties and highlights its relevance for the development of advanced agrochemical products.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"57 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020068","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, most hydrogels fail to satisfy harsh requirements of maintaining favorable performance in extreme condition due to its porous network structure and high hydrophilicity. Therefore, it is important to design hydrogel with anti-swelling ratio and underwater environmental resistance. Herein, P(AMPS/HEMA/EG) hydrogel was prepared by solvent displacement, which was polymerized by 2-acrylamide-2-methylpropanesulfonic acid (AMPS), hydroxyethyl methacrylate (HEMA) as monomer, N, N’-methylene-bis-acrylamide (MBAA) as crosslinking agent and ammonium persulfate (APS) as initiator in ethylene glycol (EG), followed by solvent displacement. Hydrophilic PAMPS chains and hydrophobic PHEMA chains endowed P(AMPS/HEMA/EG) hydrogel with anti-swelling behavior by reaching hydrophilic-hydrophobic segments balance. The sulfonic acid group formed multiple hydrogen bonds with hydroxyl groups, resulting in P(AMPS/HEMA/EG) hydrogels exhibiting great mechanical properties. The free negatively charged sulfonic acid group and the ionized positively charged hydrogen ions endowed the P(AMPS/HEMA/EG) hydrogel with conductivity. Based on this strategy, the hydrogel showed anti-swelling ratio and underwater environment resistance. After 30 days soaking in 60 ℃ deionized water, 0.2 M NaCl and NaNO₂ solution and acetone, the swelling ratio were −44.05 %, 0.44 %, −12.12 % and –23.96 %, respectively. Furthermore, the mechanical property stability of hydrogel was enhanced by the strong hydrogen bond after solvent displacement. The stress of hydrogel increased by 119.62 % after immersing in 0.6 M NaCl solution for 15 days. Based on the above properties, the hydrogels could be employed as flexible sensor in amphibious environment. Therefore, this environmental resistance hydrogels possessed profound impact on wide range applications.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"12 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020062","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}

Carboxyl-modified perovskite-MSN nanocomposites were employed to label anti-gliadin monoclonal antibody (mAb) and construct dual-mode fluorescent ICA (FICA) for determination of gliadin in milk and beef samples. Compared to the traditional AuNP-based colorimetric ICA strips, the CsM-H-based FICA demonstrated improved sensitivity, with a limit of detection (LOD) of 3.62 ng/mL in quantitative analysis. The CsM-H-based FICA strips exhibited average recoveries ranging from 90.2 % to 110.0 %, with coefficients of variation (CVs) between 3.3 % and 7.4 % for milk and beef samples. The ultra-stable perovskite-MSN nanocomposites provided the FICA strip with excellent stability, enabling storage for up to six months at room temperature.

Cu foil has been extensively investigated in the ECH reaction of furfural (FF) into furfuryl alcohol (FA) and 2-methylfuran (MF) while its catalytic performance is still impeded by its intrinsically flat surface. In this study, we propose a facile approach to improve the ECH reaction of FF over Cu foil by surface modifications with MOF-808, a Zr-based metal–organic framework with abundant terminal –OH/OH₂ groups. The coordinatively unsaturated Zr site (Zr-CUS) present in framework could act as Lewis acid center to interact with the carbonyl oxygen of FF, thus facilitating the diffusion of FF from the electrolyte solution to near-surface region of Cu electrode. The terminal –OH/OH₂ functional groups on the node could serve as proton donors and/or acceptors, thereby creating the proton-rich environment at the surface of Cu electrode. The findings in this study demonstrate an effective strategy to enhance the electrocatalytic performance of metal foil electrode <em>via</em> the modifications with rationally designed MOF overlayer.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"27 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020067","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}

Cellulose acetate (CA) is an environmentally friendly filtration material with great application potential. However, its polyhydroxyl structure and weak polarization make it difficult to construct high electrostatic, which is not conducive to filtration. Here, we report a molecular chain spacing expansion strategy for achieving high-performance cellulose-based electrospun materials for air filtration by coordination with copper ion (Cu²⁺). Through the coordination we show that the restriction of CA hydrogen bonding network for its dipole orientation polarization under the external electric field (independent polarization properties) is weakened, i.e., its dipole moment was greatly improved from 5.23 debye to 8.86 debye. Due to its high surface potential (7.97 kV), the Cu²⁺-coordinated CA film exhibits excellent filtration performance with a high PM 0.3 removal efficiency of 99.15 % and a low pressure drop of 37.3 Pa, which is 39.98 % higher than that of the pure CA film. Moreover, by comparing the filtration performance of particles with different sizes (PM 0.3, PM 0.5, PM 1.0), it is found that the electrostatic adsorption works better for smaller particles.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"84 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020072","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}

An electrode with charge capture functionality was created by doping with carbon spheres (CS).
