Over the past decade, significant advancements have been made in the hydrosilylation process for modifying porous silicon (pSi) surfaces.

The reclaimation of REEs from wastewater stands as a significant supplementary strategy to bolster the REEs supply. Adsorption techniques are widely recognized as environmentally friendly and sustainable methods for the separation of REEs from wastewater. Despite the growing interest in adsorption-based REEs separation, comprehensive reviews of both traditional and novel adsorbents toward REEs recovery remain limited. This review aims to provide a thorough analysis of various adsorbents for the recovery of REEs. The types of adsorbents examined include activated carbons, functionalized silica nanoparticles, and microbial synthetic adsorbents, with a detailed evaluation of their adsorption capacities, selectivity, and regeneration potential. This study focuses on the mechanisms of REEs adsorption, including electrostatic interactions, ion exchange, surface complexation, and surface precipitation, highlighting how surface modifications can enhance REEs recovery efficiency. Future efforts in designing high-performance adsorbents should prioritize the optimization of the density of functional groups to enhance both selectivity and adsorption capacity, while also maintaining a balance between overall capacity, cost, and reusability. The incorporation of covalently bonded functional groups onto mechanically robust adsorbents can significantly strengthen chemical interactions with REEs and improve the structural stability of the adsorbents during reuse. Additionally, the development of materials with high specific surface areas and well-defined porous structures is benifitial to facilitating mass transfer of REEs and maximizing adsorption efficiency. Ultimately, the advancement of the design of efficient, highly selective and recyclable adsorbents is critical for addressing the growing demand for REEs across diverse industrial applications.</div></div>","PeriodicalId":239,"journal":{"name":"Advances in Colloid and Interface Science","volume":"338 ","pages":"Article 103403"},"PeriodicalIF":15.9,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143043899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to the process optimization, success of polymer assembly in encapsulation strongly lies upon the favorable molecular interactions originating from the diverse chemical environment shared between core and shell materials facilitating formation of core/shell nanostructure. Therefore, understanding particle surface related properties and interaction profile of core/shell, is pertinent to fully harness control over core/shell structure formation. In our study, employing microfluidics-assisted screening of diverse MSN cores with contrasting charged dextran derived polymers, we conducted detailed characterization using dynamic light scattering (DLS), transmission electron microscope (TEM) imaging, and molecular simulations (MD) for analyzing interaction energies and molecular interactions. Our findings reveal that self-assembly of a polymer around the MSN cores majorly proceeds among counter charged entities (core and shell). From molecular perspective, in addition to the electrostatic interactions, hydrogen bonded interactions also contribute to stabilizing polymer assembly. Contrarily, out data reveals that in case pi-cation and van der Waals interactions are dominant, encapsulation of MSN cores accomplishes regardless of particle surface charge.

These biopolymer nanofibers often synergize with other nano-building blocks to enhance gels with desirable functions and eco-friendliness across various applications in biomedical, environmental, and energy sectors. The inter-/intra-molecular interactions directly affect the assembly of nano-building blocks, which determines the structure of gels, and the integrity of connected nano-building blocks, influencing the mechanical properties and the performance of gels in specific applications.
