“…These biomass derivatives can easily achieve crosslinked carbon structures through self-assembly, so the carbon skeleton can be modulated based on its crosslinking principle to achieve the directional formation of pore structures and functional groups, fostering the synthesis of high-performance carbon electrode materials. 7,14 The seafood processing industry generates an estimated 6-8 million tons of shellsh waste each year. 15 Due to its limited economic value, it is usually dumped back into the ocean, incinerated or sent to landlls without further processing and recycling, resulting in a waste of resources and serious degradation of coastal ecosystems.…”

“…The orderly self-assembly of nanoparticles paves a broad avenue for the fabrication of functional materials endowed with optical, electrical, and magnetic properties. − Ligand-stabilized colloidal particles are particularly suited for the assembly of hierarchical structures, as the ligands dictate the interactions between the colloidal particles and their surrounding environment . At liquid interfaces, particles exhibit high mobility and can achieve assembly equilibrium in a relatively short time.…”

Magnetic polymer composite microspheres (MPCMs) with biocompatible coatings are increasingly being recognized as promising candidates for biologic separation, immunoassays, and drug delivery systems. Notwithstanding, conventional preparation methods primarily involve the simple stacking or disordered assembly of magnetic particles. In this study, carboxylate ligands of the poly(styrene-alt-maleic acid) sodium salt (PSMA-Na) facilitate the self-assembly preparation of PSDA@Fe 3 O 4 composite microspheres through bidentate bridging coordination to surface metal ions of Fe 3 O 4 . The critical role of carboxyl groups within the amphiphilic alternating copolymer PSMA-Na can be determined so that (1) these can help to establish strong coordination bonds with Fe 3 O 4 , serving as a bridge between the magnetic nanoparticles and the polymer material, thereby facilitating the capture of magnetic components; (2) more intriguingly, the magnetic materials within this system undergo a self-assembly process transitioning from the core to the shell, where the strong coordination effect of carboxyl groups results in the formation of a core−shell structure with Fe 3 O 4 uniformly dispersed on the surface of polymer microspheres. Consequently, the PSDA@Fe 3 O 4 microspheres produced exhibit controllable particle size, high magnetic loading, and excellent biocompatibility, presenting potential biomaterial applications in magnetic resonance imaging and drug delivery systems. Significantly, this self-assembly method is straightforward, swift, and widely applicable to nanoparticles and carboxylate organic molecules, offering insights and inspiration for synthesizing additional composite materials.

“…The ζ potential is a key parameter to characterize the electric structure in EDL. It plays an important role in interface science (e.g., interfacial reaction [ 24 , 25 ], self-assembly [ 26 , 27 ], etc.) and electrokinetic flow dynamics [ 28 , 29 , 30 ].…”

Zeta potential (ζ potential) is a significant parameter to characterize the electric property of the electric double layer (EDL), which is important at the solid–liquid interface. Non-uniform ζ potential could be developed on a chemically uniform solid–liquid interface due to external flow. However, its influence on the flow has never been concerned. In this investigation, we numerically studied the influence of non-uniform 2D ζ potential on the flow at the solid–liquid interface. It is found, that even without any external electric field and only considering the influence of 2D ζ potential distribution, swirling flow can be generated near EDL, according to the rotational electric volume force. The streamwise vortices, which are important in the turbulent boundary layer, are theoretically predicted in this laminar flow model when considering the 2D distribution of ζ potential, implying the necessity of considering the origin of streamwise vortices of the turbulent boundary layer from the perspective of electrokinetic flow. In addition, the ζ potential distribution can promote the wall shear stress. Therefore, more attention must be paid to shear-sensitivity circumstances, like biomedical, medical devices, and in vivo. We hope that the current investigation can help us to better understand the effect of charge distribution on interfacial flow and provide theoretical guidance for the development of related applications in the future.
