• Dynamic Sub‐Nanoscale “Water Fingers” in Interfacial Polymerization

  Zhaohuan Mai, Tomohisa Yoshioka, Akshay Deshmukh, Tianmu Yuan, Junyong Zhu, Jinkai Yuan, Ralph Rolly Gonzales, Ayano Yamamoto, Yongxuan Shi, Wenming Fu, Kecheng Guan, Zhan Li, Pengfei Zhang, John H Lienhard, Hideto Matsuyama

  Abstract Interfacial polymerization (IP) is widely used to fabricate high‐performance membranes, yet the molecular‐level dynamics that govern monomer transport across liquid–liquid interfaces remain poorly understood. Here it is reported that sub‐nanoscale “water fingers”—transient chains of water molecules—modulate the interfacial behavior of amine monomers during IP, dictating the structure and performance of the resulting polyamide films. Using molecular dynamics simulations of archetypal membrane‐forming systems (m‐phenylenediamine (MPD)–trimesoyl chloride (TMC) for reverse osmosis and piperazine (PIP)–TMC for nanofiltration), it is revealed that water fingers differentially stabilize monomer transport across the aqueous‐organic interface, correlating with experimentally observed disparities in film density and permeability. These findings offer a new physical picture of interfacial reactivity, establishing water fingers as critical, tunable elements of monomer transport. This work provides mechanistic insights into a century‐old reaction and opens new design strategies for ultrathin films and interfacial materials.

• Efficient and high-density immobilization of animal cells by a microfiber with both swelling and cell adhesion properties and its application to exosome production

  Naofumi Shiomi, Pengfei Zhang, Shuji Nakatsuka, Kazuo Kumagai, Hideto Matsuyama

  Abstract Purpose For high-density cell culture, we studied the development of optimal microfibers (MFs) with a 0.1–10 μm diameter, which due to their large surface area can serve as an immobilization carrier for animal cells. To date, few studies have used MFs as scaffolding for high-density cell culturing. Results Using six types of nonsoluble synthetic polymers, MF sheets were fabricated by electrospinning. The cellulose acetate, polyketone, and polyvinyl acetate MFs exhibited swelling and water retention capacities. Next, the six types of MF fragments were examined for immobilizing TKD2 mouse vascular endothelial cells. Although most cells were taken into the three MFs characterized by swelling, most leaked from the MFs without adhesion. To solve this, the MF sheets comprising cellulose acetate and polyketones were coated with gelatin. Although the adhesive capacity was enhanced, the swelling capacity decreased and almost all the immobilized mouse cells remained on the sheets’ surfaces. Based on these results, we produced a novel MF sheet comprising a gelatin, cellulose acetate, and polyketone mixture (CPG). Since the cells were taken into the MFs by swelling and attached by the gelatin, the CPG fragment immobilized almost all the supplied cells with little loss and reached a high density of 3.2 × 10⁹ MF-g⁻¹, Furthermore, the immobilized cells continuously produced exosomes with a high productivity of 6–7 × 10¹⁰ particles ml⁻¹ after either 8 h or 16 h of culturing. Conclusion CPG-based MFs are expected to have a wide range of future applications, including exosome production from animal cells.

• Nanoconfinement Engineering of Covalent Organic Frameworks in Polyamide Membranes for High‐Perselectivity Li⁺/Mg²⁺ Separation

  Shuzhen Zhao, Liheng Dai, Zhaohuan Mai, Bowen Li, Pengfei Zhang, Mengxiao Zhang, Atsushi Matsuoka, Kecheng Guan, Ryosuke Takagi, Hideto Matsuyama

  Abstract Efficiently separating Li⁺ over Mg²⁺ from brines remains a significant challenge due to their minimal size difference of only several angstroms, posing a substantial difficulty for traditional nanofiltration (NF) membranes. Therefore, a nanoconfinement regulation strategy utilizing a porous covalent organic framework (COF) layer is proposed to precisely control the interfacial polymerization (IP) process, thereby obtaining a thin, uniform polyamide (PA) membrane for high‐efficiency Li⁺/Mg²⁺ separation. The nanoconfinement microenvironment fundamentally modulates both monomer spatial distribution and reaction kinetics through porous confined space and abundant interaction sites provided by the COF layer. Consequently, the resulting TpPa‐S/PA membrane exhibits a narrower pore size distribution, achieving an ion sieving precision of 0.46 Å. Due to the strict size sieving effect, the Li⁺/Mg²⁺ separation factor exceeded 120, which is one to two orders of magnitude higher than all the currently reported NF membranes. This study addressed the typical limitations inherent in conventional NF membranes, establishing a promising foundation for advancing lithium extraction technologies through nanoconfinement strategy‐regulated IP processes.

• Hierarchically Structured Porous Polyamide‐Imide Membrane for Switchable Emulsion Separation

  Pengfei Zhang, Bowen Li, Ralph Rolly Gonzales, Kecheng Guan, Zhaohuan Mai, Zhan Li, Mengyang Hu, Liheng Dai, Ping Xu, Keizo Nakagawa, Tomohisa Yoshioka, Hideto Matsuyama

  Abstract The development of advanced membranes with switchable superwettability has attracted considerable attention for the efficient treatment of oily wastewater. However, challenges persist in designing and fabricating such membranes through straightforward methods. In this study, a novel strategy is presented to design switchable superwettable membranes based on micro/nano‐structured porous surfaces and surface chemical composition reorganization. A commercial amphiphilic polymer, polyamide‐imide (Torlon), is fabricated into a porous symmetric membrane with a hierarchical surface structure using a one‐step non‐solvent‐induced phase separation method. By leveraging the surface reorganization capability of amphiphilic polymers and the hierarchically porous structure, the resulting membranes demonstrate exceptional superamphiphilicity in air, underwater superoleophobicity, and underoil superhydrophobicity. These properties enable ultrahigh permeance and separation efficiency for oil‐in‐water, water‐in‐oil, and crude oil/water emulsions through a gravity‐driven process, eliminating the need for external energy. Furthermore, the membranes exhibit excellent antifouling and self‐cleaning performance, maintaining stable operation over multiple cycles. This work provides an innovative and scalable approach to next‐generation switchable superwettable membranes with broad potential applications in oily wastewater treatment and beyond.

  Abstract Polyacrylonitrile (PAN) adsorptive membrane incorporated with nanosize-goethite (α-FeO(OH)) hydrous metal oxide particles (GNPs), prepared with optimal flux and Cu(II) removal in the previous study, was used to evaluate the process parameter on the Cu(II) removal. Box-Behnken Design (BBD) based on the Response Surface Methodology (RSM) was employed to evaluate the impact of Cu(II) feed solution characteristics such as pH, initial concentration of metal ion, and transmembrane pressure (TMP) on copper removal efficiency. The outcomes indicated that the RSM optimization technique could be utilized as an applicable method to find the optimum condition for the maximum Cu(II) removal with slight variance compared with the experimentally measured data. The effect of each process parameter and the coupling effect of parameters on the Cu(II) removal was assessed. Finally, the optimum condition of pH, Cu(II) concentration, and transmembrane pressure (TMP) to obtain high copper removal efficiency was decided. In the optimum condition of the Cu(II) removal, the removal of lead (Pb(II)) metal ion was evaluated by the same membrane.
