Having relied for a long time on chemical and physico-chemical means with non-negligible environmental impact, these sectors are increasingly exploring the use of physical phenomena to improve cleaning efficiency. We summarise here recent progress in the area of cleaning methods that exploit the physical properties of liquid interfaces created by liquid menisci, bubbles, drops or foams. The high energy of these interfaces leads to a complex interplay between (1) interfacial forces, (2) viscous stresses created by flow fields under confinement, and (3) the capacity to adsorb solid and liquid contaminations. In appropriately designed cleaning processes, this interplay can reach an astounding efficiency, in many cases even with pure water, i.e. in the absence of any detergent. We will also show that whilst foams have always been assumed to be a mere side product of cleaning processes, recent research puts in evidence that they can actually be highly efficient cleaning agents, provided that their physical properties are properly chosen. We discuss a wide range of examples in which different interface-based cleaning methods have been investigated, including solid and liquid contaminations, or biological contaminations (bacteria, biofilms and biofouling).</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"72 ","pages":"Article 101818"},"PeriodicalIF":7.9,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029424000360/pdfft?md5=9c7678121ea012f8b273a4e3fd04139f&pid=1-s2.0-S1359029424000360-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gaining a deeper understanding of their molecular behavior at various interfaces is thus becoming ever more essential. Despite considerable advances in experimental techniques, challenges in capturing the detailed molecular-level behavior of surfactants at interfaces persist. In this work, we discuss the potential of combining various experimental methods with atomistic molecular dynamics (MD) simulations in studies of surfactant interfacial layers. MD simulations have emerged as a powerful tool that provides detailed insights into molecular structures and dynamic properties, some of which are inaccessible through experimental means alone. By re-examining existing MD simulation data and directly comparing them with experiments, we illustrate how MD simulations can be used to validate and support thermodynamic models and interpret spectroscopy and scattering data. While combining scattering experiments on Langmuir layers of insoluble surfactants with simulations seems to be well-established by now, we emphasize the growing capability of scattering techniques to also investigate the more disordered Gibbs layers of soluble surfactants. Here, MD simulations can now connect the pressure and adsorption isotherms with the equation of state. In light of the ongoing parallel developments of computational and experimental methods, their synergistic use can be expected to drive future progress in surfactant research.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"72 ","pages":"Article 101816"},"PeriodicalIF":7.9,"publicationDate":"2024-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029424000347/pdfft?md5=367aaf6b1fdd28a169d0b3ff1fe7fded&pid=1-s2.0-S1359029424000347-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
