Abstract Designing well‐ordered, multifunctional layered membranes with high selectivity and long‐term stability remains a significant challenge. Here, simple strategy is introduced that utilizes charge repulsion between graphene oxide (GO) engineered bacteria to induce liquid crystal formation, enabling their layer‐by‐layer self‐assembly on polyethersulfone membrane. The interlayer pressure flattens the bacteria, removing water forming densely packed structure. This compression decreases spacing functional groups, leading robust hydrogen bonding network enhancement in mechanical properties (12.42 times tensile strength increase). Notably, preserves activity of super uranyl‐binding protein which selectively coordinates uranyl (UO 2 2+ ) through high‐affinity coordination bonds, recognition sieving target ions. membrane demonstrates near 100% rejection UO , K/U, V/U ≈140 ≈40, respectively, while maintaining stability. provides versatile platform for precise design high‐performance membranes, advancing field molecular transport energy environmental applications.

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

Heterogeneous confinement systems attract increasing attention owing to their widespread applications in diverse areas. However, it is still lacking an in-depth understanding of the diffusion mechanism and physical properties water heterogeneous nanochannel through molecular simulations. Here, high-precision TIP4P-BGWT molecules confined molybdenum disulfide (MoS2) graphene walls are utilized investigate influences variables, i.e., channel height, wettability walls, charge MoS2, temperature, on properties. The simulation results indicate that significantly affected by height temperature but weakly influenced walls. Observable impacts can be observed with slight Considered excluding remarkably influence density distribution, while limiting mean square displacement at depends solely upon effective distance. It worth noting that, compared homostructure, significant discrepancy distribution obtained from due different solid-liquid interactions. present study offers a solid foundation for design nanodevices, such as nanomembrane, nanosensor, microfluidic chip, etc.

Abstract Inspired by the natural process of transpiration‐induced selective water and nutrient absorption, a solar evaporation‐driven lithium extraction method has been developed integrating interfacial evaporation with ion‐selective membrane separation, which provides an alternative pathway toward energy‐, cost‐efficient mining. However, practical implementation is challenging due to conventional evaporator's salt scaling cavitation problem. To address these problems, superhydrophilic evaporator embedded high water‐retaining polymer designed generate ultrahigh negative pressure (−59 MPa), enabling sustained flow inhibiting crystallization. Under one sun irradiation (1 kW m −2 ), demonstrates high‐water rate 2.43 kg h −1 ; it then facilitates delivery Li + , resulting in enrichment evaporator. By optimizing polyamide (PA)‐based membrane, solar‐driven system excellent /Mg 2+ separation performance, achieving factor 15.6. Outdoor experiments demonstrate robust performance when treating lake brines, as retains hydration prevent ensure continuous ion enrichment. This research advances material design for desalination recovery, offering promising solution tackle global supply challenges.

Efficient lithium extraction from salt lakes is essential for a sustainable resource supply. This study tackles the challenge of separating Li+ Mg2+ in complex brines by innovatively integrating two-dimensional (2D) graphene oxide (GO) with bimetallic metal–organic frameworks (MOFs). Zn2+ and Co2+ ions are confined within GO interlayers through an situ synthesis, forming 2D Zn-Co MOFs/GO membrane (Zn-Co-GOM). design exploits unique advantages MOFs, including enhanced structural stability superior ion separation capabilities due to synergistic effects Zn Co. The Zn-Co-GOM demonstrates impressive factor 191 over Mg2+, significantly surpassing traditional membranes. exceptional selectivity achieved combination size exclusion transport energy barriers. Our approach not only enhances practical application technology but also provides valuable insights into underlying mechanisms.
