However, limitations such as stringent preparation conditions, long reaction times, and low yields restrict their further application. Herein, an instantaneous and continuous approach is proposed to synthesize multimetallic MOF nanoparticles utilizing high gravity technology. With greatly enhanced mixing and mass transfer in the rotating packed bed reactor, the instantaneously synthesized bimetallic/trimetallic MOF nanoparticles show smaller particle sizes, higher surface areas, and greatly enhanced OER performance compared with the corresponding stirred tank reactor products. Density functional theory calculations elucidate the intrinsic activity regulation mechanism of bimetallic MOFs. This study not only proposes an efficient strategy to synthesize multimetallic MOFs for OER but also can achieve scaled-up preparation with ultra-high space–time yield (43,700 kg m−3 day−1), promoting the practical application of MOFs in electrocatalysis.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532319","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, there is still a lack of systematic research on how the liquid properties affect the hydrodynamics and mass transfer characteristics of a single microbubble. In this work, the diameter, velocity, and mass transfer of a single microbubble in liquids with different properties were analyzed by using high-speed photograph technology. It was found that the rise velocity was minimally affected by the surfactant but decreased with the increase of liquid viscosity. A new velocity correlation was developed to predict the rise velocities of microbubbles, with deviations within 20%. The addition of surfactants and increasing liquid viscosity both reduce the mass transfer coefficient (kL) compared to ultrapure water. Conversely, kL increased by 1.3 to 4.1 times as the reactant concentration increased in chemical absorption. This study provides meaningful data to understand the hydrodynamic behaviors and mass transfer characteristics of microbubbles.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532309","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}

In this study, the rigidity and flexibility coupled concept was employed to engineer rigidly confined ion-selective channels within MAPMs to facilitate anion separation. The rigid segments self-assemble into micropores (<0.8 nm), with dimensions precisely modulated by the flexible segments. Under electrodialysis conditions, these membranes demonstrate an order-of-magnitude improvement in selectivity compared with Neosepta® ACS commercial membranes (special for anion separation), with a slight increase in the permeation flux of monovalent anions. The simulation results confirm that the difference in the confinement of various anions, driven by electrostatic interactions within the rigid micropores, is responsible for the exceptional monovalent/bivalent selectivity. Overall, this study provides an alternative strategy to construct rigidly confined channels for efficient anion separation.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143517906","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}

Therefore, bioprospecting efforts focused on anaerobic microbial diversity could rapidly uncover new enzymes, pathways, and chassis organisms to drive biotechnology innovation. Despite their potential utility, anaerobic fermenters are viewed as inefficient from a biochemical perspective because their metabolisms produce fewer ATP (~2) per molecule of glucose processed than heterotrophic respirers (~32–38 ATP). While aerobes excel at ATP generation, they are often less efficient than anaerobes at processes that compete with ATP generation for cellular resources. This perspective highlights how anaerobic adaptations are advantageous for synthetic biology and biomanufacturing applications through the engineering of microbial cell factories. We further highlight emerging applications of anaerobic bioprocessing, including the use of anaerobic metabolisms for lignocellulosic bioprocessing, human and environmental health, and value-added bioproduction.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/aic.18797","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we propose a novel selective electrodialysis with bipolar membranes (BMSED) process for simultaneous cobalt and lithium recovery from a citric acid-leaching lithium-ion battery solution. By taking advantage of the accelerated water dissociation of bipolar membranes and the monovalent selectivity of Li+ over Co2+ ions from selective electrodialysis, one-step preparation of 99.96% purity LiOH, cobalt salt, and 0.63 mol/L citric acid solution was achieved. The steric hindrance effect of citrate across anion-exchange membranes was investigated via positron annihilation lifetime spectroscopy characterization. The competitive migration between the proton and metal cations across the cation-exchange membrane could decrease the current efficiency. A carbon footprint analysis revealed that the BMSED procedure accounted for only 18.40% of the total carbon emissions, demonstrating the environmental friendliness of this recycling method.","PeriodicalId":120,"journal":{"name":"AIChE Journal","volume":"71 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495627","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}
