To address the operational lifetime of PHEs under fouling conditions and determine optimal repair time, a virtual framework is required to function as a digital twin. This study investigates the application of a vinyl acetate copolymer nano-coating on PHEs to reduce the fouling thickness of CaCO₃ using a Multiphysics simulation approach. The novelty of this work lies in the development of a numerical framework capable of accurately forecasting optimal repair times before the system's efficiency declines. The results reveal that nanocoating reduces the thermal resistance and the fouling thickness by 65.77% and 58.8%, respectively, compared to the uncoated sample. The proposed framework accurately determines the thermodynamic behaviour of the PHE as a digital twin and predicts the appropriate time for its repair or replacement.</p>","PeriodicalId":8898,"journal":{"name":"Biofouling","volume":" ","pages":"1-15"},"PeriodicalIF":2.0,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review presents a comprehensive bibliometric analysis of global research trends, challenges, impacts and future opportunities in antibiofouling membranes. Utilising Bibliometrix in R and advanced visualisation techniques, 172 publications from 2006 to 2023 were analysed, with data extracted from Scopus and Web of Science databases accessed on December 5, 2024. Key bibliometric indicators, including total citations, co-authorship networks and keyword co-occurrences, were explored to map the scientific landscape. The findings reveal a steady growth in research, with the most cited publication achieving 452 citations and an average of 45.2 citations per year. Surface modification emerged as the dominant theme, occurring 60 times and achieving the highest betweenness centrality of 1,252.975, highlighting its role in improving antifouling and biofilm resistance. Other critical research areas include nanofiltration, reverse-osmosis membranes and the integration of advanced materials like graphene oxide, silver nanoparticles and polydopamine. Interdisciplinary collaborations among material science, chemistry and environmental engineering were identified as key drivers of innovation. Despite advancements, gaps persist in scaling up technologies, addressing environmental sustainability, and applying antibiofouling membranes in underexplored areas like seawater desalination and wastewater treatment. Emerging trends, including energy-efficient solutions, biofilm mitigation and computational modelling for predictive performance, present significant opportunities for future research. This review underscores the transformative potential of antibiofouling membranes in enhancing operational efficiency and sustainability. By addressing identified research gaps and fostering interdisciplinary approaches, this study provides actionable insights and a strategic roadmap for researchers and policymakers to advance antibiofouling membrane technologies to meet global water and environmental challenges.</p>","PeriodicalId":8898,"journal":{"name":"Biofouling","volume":" ","pages":"1-18"},"PeriodicalIF":2.0,"publicationDate":"2025-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145278962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TOH-Ti-NL also displayed higher surface roughness, linked to improved osseointegration, and a higher release rate than Carv-Ti-NL. Both coatings eradicated bacteria within 24 h.

An important result for both biomass and extracellular polymers measurements, was that ethanol fixation group values were lower than other fixation methods (<i>p</i> < 0.001). The morphological formations, which were observed as small cohesive groups with ethanol fixation, were seen as adhesive groups with glutaraldehyde fixation. The application of glutaraldehyde in the fixation of biofilms produced by <i>M. furfur</i> yielded a greater range of absorbances, thus facilitating more comprehensive data evaluation than that achieved with ethanol.

Despite the global ban on tributyltin, many copper-based and organic biocides remain in use, contributing to sediment pollution and potential contamination of coastal aquifers. Biofouling also reduces the efficiency of desalination and water infrastructure, increasing costs and straining freshwater access in vulnerable regions. Saltwater intrusion, intensified by sea-level rise and groundwater overuse, further threatens groundwater quality. While green antifouling technologies show promise, adoption is limited in resource-constrained areas.
