This critical review provides a comprehensive analysis of recent advances in ceramic membrane-based oil-water separation, with a focus on separation mechanisms, anti-fouling performance, and surface modification strategies. The underlying mechanisms governing oil-water separation, including size exclusion, wettability-driven demulsification, and the role of membrane surface energy, are critically examined. Moreover, the anti-fouling mechanisms, particularly the design of hydrophilic and underwater oleophobic surfaces, are discussed in relation to reducing irreversible membrane fouling. Finally, a systematic evaluation of surface modification strategies, such as grafting of functional polymers, nanoparticle coating, and inorganic surface engineering, is presented, highlighting their effectiveness and limitations. This review also identifies current challenges, including trade-offs between permeance and selectivity, long-term stability of modified surfaces, and scalability of modification methods.

This study presented a scientometric and big data analysis of 8737 publications on MCs in HCRs from 1991 to 2025, systematically mapping the research landscape, evolutionary hotspots, and dynamic catalytic behaviors. Research on MCs experienced explosive growth in 2025 with 762 publications. Bruce C. Gates stands out as a prominent researcher in MCs, contributing significantly with 85 publications. Keyword co-occurrence and systematic cluster analysis reveal four sequential stages: (1) synthesis and characterization, (2) catalytic performance and mechanism, (3) support engineering and interface control, and (4) dynamic behavior and design optimization. Gold, palladium, and platinum clusters remain the most extensively studied MCs, but stage trend factors show that copper (+0.235), iron (+0.196), and nickel (+0.097) exhibit the strongest recent momentum. Unlike single-atom catalysts lacking adjacent metal sites and nanoparticles with rigid bulk-like structures, MCs uniquely combine reversible structural dynamics, adsorbate-induced adaptability, facile redispersion, and optimal ensemble effects, enabling superior catalytic performance in complex reactions. Recent advances have further emphasized dynamic structural evolution under operando conditions, AI-accelerated catalyst design, and synergistic cluster–single-atom architectures, marking a transition from static design to adaptive catalysis. This work not only charts the evolutionary landscape of MCs but also uncovers the dynamic mechanisms that distinguish them from other catalysts, offering a quantitative roadmap and theoretical foundation for the rational design and sustainable applications of next-generation MC catalysts in energy and environment.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"25 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147752860","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}

Here, we exploit these topological properties to develop a fluorescent-temporal (FLUO-TIME) barcoding platform termed CLOCK (CLOsed Circular DNAzyme Kit), which significantly expands multiplexing capacity without requiring additional spectral channels. CLOCK utilizes an engineered C-Dz design where topology regulates functional differentiation for synergistic encoding: the loop sequence enables traditional fluorescence encoding via hybridization, while the loop size modulates catalytic core folding through topological rigidity. This constraint regulates cleavage efficiency, allowing for the programmable kinetic control of rolling circle amplification, which is achieved by varying the loop length to tune the topological constraint of the catalytic core. By combining spectral signatures with distinct time-to-peak fluorescent signals, CLOCK generates a multidimensional FLUO-TIME barcode. Structural insights from AlphaFold3 and molecular dynamics simulations further provide new perspectives on how topological constraints affect the enzymatic activity of C-Dz. As a proof of concept, CLOCK achieved one-pot detection of four respiratory virus RNAs with a sensitivity of 1 fM.
