Current research highlights the crucial role of morphology in enhancing device performance. However, achieving higher efficiencies requires improved charge dissociation, balanced charge transport, and minimized energy loss and recombination, which is not always attained.

Hence, in the context of growing demand for “green” technologies and potential mismanagement of their life cycle, understanding their potential mobility within and between environmental compartments becomes crucial for evaluating their environmental risks. Colloids emerge as primary carriers/vectors facilitating REE mobility and transfer in the environment. This work addresses major topics related to the control exerted by colloids on the REE speciation and subsequent patterns. Among colloids, iron-organic matter colloids have been identified as the major REE carrier in surface water under various pedoclimatic conditions. Compelling evidences were provided that the mixing of iron-, organic- and iron-organic colloids could explain both REE concentration and pattern under environmental conditions. However, there is currently a lack of data on the specific distribution of REE between the iron and organic matter phases within Fe-OM colloids. It remains unclear whether REE distribution is primarily controlled by colloid mixing since structural rearrangements of Fe-OM colloids under varying hydrological and physicochemical conditions exert also a significant role.</div></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"74 ","pages":"Article 101859"},"PeriodicalIF":7.9,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142326615","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}

In this review, we considered several new developments of previously proposed models, which can be used for the analysis of new experimental data. In the presence of such effects, the behaviour of the dilational viscoelasticity becomes more complicated and requires more parameters for its description. An alternative way is to use phenomenological models, which do not identify the particular relaxation processes but propose a description of the dilational viscoelasticity in general terms.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"74 ","pages":"Article 101849"},"PeriodicalIF":7.9,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142271565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first discuss foam structures, transitioning from ball to wet and dry foams, influenced by the liquid fraction and surfactant presence, which also influence the foam’s mechanical and stability properties. We further describe the mechanisms of foam generation (for confined foams), stability, and decay, highlighting the roles of snap-off, lamellae division, and leave-behind in foam formation and the adverse effects of coarsening, gravity drainage, and collapse on foam stability. Additionally, the review covers the rheological behavior of foams under shear stress, illustrating their complex viscoelastic or viscoplastic nature. Finally, we review recent studies of foam injection and displacement in porous structures, utilizing Hele–Shaw cells and microfluidics.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"74 ","pages":"Article 101845"},"PeriodicalIF":7.9,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029424000633/pdfft?md5=db5cfbca774cfeef81ccfba7587e20c3&pid=1-s2.0-S1359029424000633-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142163338","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}
