The inherent trade-off between permeability and selectivity has constrained further improvement of passive linear force-electric conversion performance in nanofluidic pressure sensors. To overcome this limitation, a 3D membrane with high mechanical strength utilizing aramid nanofibers/carbon nanofiber (ANF/CNF) dual crosslinking is developed. Due to the abundant surface functional groups CNF ANF, large-scale integrated exhibits advantages flux, porosity, short ion transport path, demonstrating superior response compared conventional 1D 2D configurations. enhancement mechanism ANF/CNF systematically investigated through experimental results theoretical calculations. optimized device sensitivity 111 nA cm

Extracting lithium from salt lakes requires ion-selective membranes with customizable nanochannels. However, it remains a major challenge to separate alkali cations due their same valences and similar ionic radius. Inspired by the K+ channel of KcsA K+, significant progress has been made in adjusting nanochannel size control ion selectivity dominated dehydration. Besides, several works involved incorporating ligands, such as crown ether, into nanochannels based on coordination chemistry try promote cation selectivity; nevertheless, only separation between mono-/bivalent achieved. Herein, series heteropolyacid (HPA) ligands are designed functionalize two-dimensional (2D) nanochannels, achieving superior perm-selectivity over other (16 for Li+/K+), Li+ permeation rate increased four times that pristine 2D membrane. We discover switching an its hydration ion-HPA states elucidates transport, relatively lower depth energy well exchange Li+-HPA results cations. This work demonstrates principle exploring novel develop cation-selective membranes, expanding potential applications extraction aquatic sources.

Abstract High-performance Ti 3 C 2 T x fibers have garnered significant potential for smart enabled fabrics. Nonetheless, a major challenge hindering their widespread use is the lack of strong interlayer interactions between nanosheets within fibers, which restricts properties. Herein, versatile strategy proposed to construct wet-spun in trace amounts borate form crosslinking significantly enhance as supported by density functional theory calculations, thereby reducing spacing, diminishing microscopic voids and promoting orientation nanosheets. The resultant exhibit exceptional electrical conductivity 7781 S cm −1 mechanical properties, including tensile strength 188.72 MPa Young’s modulus 52.42 GPa.

Abstract The extraction of lithium (Li) from complex brines presents significant challenges due to the interference competing ions, particularly magnesium (Mg 2 ⁺), which complicates selective separation process. Herein, a strategy is introduced employing charge‐lock enhanced 2D heterogeneous channels for rapid and uptake Li⁺. This approach integrates porous ZnFe O 4 /ZnO nanosheets into Ag + ‐modulated sub‐nanometer interlayer channels, forming optimized Li⁺ extraction. novelty lies in mechanism, selectively captures Mg ⁺ thereby facilitating effective Li Mg. mechanism driven by charge transfer during formation /ZnO, rendering atoms Fe‐O bonds more negatively charged. These negative charges strongly interact with high density enabling charge‐locking targeted capture ⁺.

Abstract Membranes with precise Li + /Na and /K separations are imperative for lithium extraction from brine to address the supply shortage. However, achieving this goal remains a daunting challenge due similar valence, chemical properties, subtle atomic‐scale distinctions among these monovalent cations. Herein, inspired by strict size‐sieving effect of biological ion channels, membrane is presented based on nonporous crystalline materials featuring structurally rigid, dimensionally confined, long‐range ordered channels that exclusively permeate naked but block Na K . This naked‐Li ‐sieving behavior not only enables unprecedented selectivities up 2707.4 5109.8, respectively, even surpassing state‐of‐the‐art membranes at least two orders magnitude, also demonstrates impressive /Mg 2+ /Ca separation capabilities. Moreover, bioinspired has be utilized creating one‐step strategy natural brines rich in , Mg without utilizing chemicals or solid waste, it simultaneously produces hydrogen. research proposed new type ion‐sieving provides an envisioning design paradigm development advanced membranes, separation, extraction.
