This work combines telecentric vision probe and bubble boundary R-CNN with a newly developed multi-input ConvNeXt to pioneer bubble shape classification under realistic flow conditions. The classification results demonstrate that ellipsoidal bubbles constitute the predominant shape (49.5%), while oblate ellipsoidal bubbles represent the smallest proportions (2.7%). Statistical analysis of E and dm across all classified bubbles reveals significant distinctions: spherical and oblate ellipsoidal bubbles exhibit pronounced differences in E compared to other classes, whereas the remaining shapes show relative consistency. dm varies substantially across classes, progressively increasing in the order: spherical, ellipsoidal, spherical cap, ellipsoidal cap, oblate ellipsoidal, and wobbling ellipsoidal. While our model achieves bubble classification, unresolved issues span image quality constraints, 3D shape inference from 2D data, turbulent flow coupling, and high-velocity applicability—necessitating integrated imaging-algorithm advances.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"18 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183268","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 trade‐off between membrane permeance and selectivity remains a great challenge. Herein, we propose a bidirectional control strategy to manipulate the chaotic ternary reaction for the construction of ultrapermeable, highly selective, and antifouling membranes. Through the introduction of glycerol, the ternary reactions among phenolic compounds, polyethyleneimine, and metal ions are bidirectionally regulated. Mechanistic investigation reveals that glycerol facilitates the coordination reactions but restricts the covalent reaction. Thus, a thinner and more hydrophilic selective layer with a more negatively charged surface is constructed. The membrane achieves an ultrahigh permeance of up to 100 L m−2h−1bar−1, and selectivity of over 100 toward salts and antibiotics, surpassing the state‐of‐the‐art nanofiltration membranes. Furthermore, the universality of our bidirectional control strategy is demonstrated in a variety of important systems, paving a novel way for synthesizing the next‐generation nanofiltration membranes for diverse applications.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"3 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181127","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 develop a high-capacity aqueous organic slurry flow battery (AOSFB) by introducing a multiphase electrolyte to break through the limitation of solubility. Three carbon additives are evaluated as electron conductors, among which Ketjen black (KB) shows superior dispersibility, thereby forming an effective percolation network. Rheological analysis reveals a liquid-to-gel transition with increasing carbon volume fraction, with 20 vol% KB achieving an optimal balance between conductivity and viscosity. This conductive network ensures uniform reaction distribution within the reactor, yielding a low overpotential. As a demonstration, an AOSFB employing 1.75 M 2-quinoxaline carboxylic acid (56% beyond its solubility) achieves a record capacity of 88.4 Ah L−1. The multiphase concept presents one universal strategy to decouple the capacity from the solubility constraint in flow battery systems.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"61 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141017","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}

As an emerging oxide material, high‐entropy oxides (HEOs) are regarded as promising OER electrocatalysts owing to the multielement synergistic effect. Herein, a facile approach is proposed to synthesize Mo‐doped high‐entropy spinel oxide Mo‐(FeCoNiCrMn)3O4 nanoparticles (Mo‐HEO). Interestingly, only low‐content Mo doping into HEO can reduce the crystallite size, prevent particle agglomeration, and modulate the electron structure. Consequently, the electrocatalyst of 6% Mo‐HEO exhibits superior OER performance with overpotentials of only 280 and 324 mV at 10 and 100 mA cm−2. In situ Raman spectroscopy confirms the transformation of surface spinel sites to metal oxyhydroxide, highlighting the Mo‐driven surface reconstruction. Furthermore, Mo doping as a versatile strategy has been successfully extended to other spinel oxides with significant activity improvements, offering a great potential in the development of spinel‐typed HEO electrocatalysts.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"4 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145089127","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}

Alkaline hydrolysis offers a sustainable approach to degrade PET into terephthalic acid (TPA) for high-value metal–organic frameworks (MOFs), yet mass transfer limitations hinder efficiency. Here, we pioneer the application of high-shear reactors (HSR) to enhance hydrolysis through intense shear stress and turbulence. Benefiting from higher rotor speed and narrower shear gap, PET flakes are fragmented into smaller particles with surface microstructures, significantly increasing specific surface area and ester group exposure, which leads to a 2.4-fold increase in degradation compared to high-speed stirring. Ethanol-induced PET swelling and turbulence-driven surface renewal synergistically enhance OH−/COO− interaction, enabling 98.6% PET degradation in 8 min (5.00 wt.% NaOH). Recycled TPA is used to synthesize UiO-66, which has applicability in carbon dioxide adsorption.

However, controlling over ORR selectivity remains challenging due to the competing four-electron pathway (i.e., over-reduction of oxygen to water). We propose optimizing catalytic performance by tuning cohesive interactions using pyridine-based porphyrin catalysts. The positioning of pyridine nitrogen (ortho-, meta-, and para-N) modulates intra- and intermolecular interactions through metal coordination and/or support incorporation. Metal coordination fine-tunes the catalytic center's electronic structure, significantly enhancing two-electron selectivity, while carbon nanotube integration boosts activity to industrially relevant current densities. The optimized system demonstrates robust stability in a flow cell prototype, maintaining high performance without degradation. Techno-economic analysis reveals low production costs (~60% market price), confirming practical viability and profitability.
