Herein, covalent organic framework membranes with adjustable pore sizes (⁓ 2.5 nm and ⁓ 1.2 nm) and chemical groups (−F, −OH, and −CO−) were prepared by interfacial polymerization. We demonstrate that strong channel–molecule attraction induces the formation of stable solvent layers along nanochannel walls, which protect central molecules from the attraction of chemical groups. Significantly, stable solvent layers permit fast transport of ethanol (245.6 L m−2 h−1 bar−1) with reactive black (RB) rejection of 96%. Likely, for membranes with weak channel–molecule attraction, no solvent layers are formed and molecules also transport smoothly. Interestingly, membranes that exhibit moderate channel–molecule attraction exert metastable solvent layers, thus displaying high transport resistance. This hindrance effect on molecule transport becomes more pronounced in smaller nanochannels.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"65 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142880175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 sluggish H species binding step severely inhibits reaction equilibrium and cause C-C cleavage. Herein, we propose a unique directional H spillover strategy driven by controlling electron transport direction via constructing Au-O-Cu-O-Mg/Al interfacial structure, to allow H species transfer from O-H dehydrogenation Cu2+ site to C-H dehydrogenation Au site to promote H2 formation. The structure that each Cu precisely terminated by Mg/Al is inherited from layered double hydroxides with orderly dispersed atom arrangement. Comprehensive studies substantiate that the unreducible Mg2+/Al3+ blocks electron transfer toward support, whereas Au-O-Cu electronic interaction drives H spillover from the support to Au. The Au/CuMgAl catalyst demonstrated unprecedentedly high glycerol dehydrogenation activity, showing 3–10 times turnover frequency (1.18 × 104 h−1) than other biomass-derived H2 formation system, co-producing lactic acid with selectivity up to 98.8%.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"2 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we introduce a novel coarse-graining strategy that employs the Lennard–Jones (LJ) potential to model solvent–solvent and solute–solvent interactions that control mesoscale behaviors. Our approach maintains the accuracy in capturing essential thermophysical properties such as densities and vapor pressures, while simplifying the representation of solvent molecules. By aggregating multiple solvent molecules into a single bead, our model offers a robust tool for studying solvation properties in systems where the collective behavior of solvents plays a crucial role. This approach enables effective computational studies across various mesoscale phenomena, including phase transitions in polymer blends, concentrated solutions of small organic molecules, and biological self-assembly. We demonstrate the robustness of our approach by simulating a saturated cholesterol–ethanol solution, exemplifying its power to tackle large-scale systems with precision and efficiency.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 3","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142874216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TSM and its corresponding experimental setup are established, and the CFD model is verified through flow field visualization experiments. Results reveal that efficient chaotic convection in TSM is achieved through continuous irregular spatial fluid deformation. The Lyapunov exponents greater than zero indicate the existence of chaotic behavior, and the maximum lineal stretch rate λM increases linearly with the characteristic Reynolds number. The mass transfer characteristics are evaluated by diffusion mass transfer number Φ and mass transfer field synergy number Fc quantitatively. The mixing index MI shows an increasing trend as Fc increases, while the mixing effectiveness ME decreases as the outlet Reynolds number ReO decreases. The relationships of MI with λM and Fc and the relationship of ME with ReO are established.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"261 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, MFI zeolite encapsulated Pt species with tunable Si/Al ratios were synthesized to allow the formation of Pt nanoparticles (NPs) with almost the same loading amount, particle size, and electronic state. Confining Pt NPs allows the spatial satisfaction for the synergy of metal centers and acid sites, and Pt@ZSM-5(100) with a moderate Si/Al ratio performed high efficiency in the conversion of carbonyl compounds and boosted high TOF of 23,409 h−1 in reductive amination of benzaldehyde. Combined with structure refinement, x-ray absorption fine structure (XAFS), in situ Fourier transforms infrared (FTIR) spectroscopy, and theoretical calculation, the study indicated that modulating the Si/Al ratio enables the fine rationalization of the microenvironment. The moderate Si/Al ratio causes suitable acid intensity that significantly contributes to the carbonyl compound activation and product desorption.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"114 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
