Abstract ：
Two-dimensional (2D) nanofluidics technology has shown great potential in efficient osmotic energy harvesting, but the lack of anion-selective 2D nanofluidic membranes limits the development of full concentration cells towards real-world applications. Herein, an anion-selective 2D nanofluidic membrane (2D-NFM) was constructed based on hydrotalcite-like layered double-hydroxides (LDHs), whose naturally positively charged surface and nanoconfined interlamellar channels endowed the membrane with excellent anion selectivity in a wide range of electrolyte concentration. The selective anion transport was further confirmed by the lower calculated transmission barrier of anions compared with the cations based on the strong electrostatic interaction within the positively charged nanochannels. Benefiting from good hydrophilicity and narrow nanochannels, the output power density of the 2D-NFM in an NaCl solution with a 50-fold concentration gradient could reach 3.06 W m-2, while the value could reach 3.92 W m-2 when natural seawater and river water were used as electrolytes. This work is expected to provide an effective strategy for constructing high-performance anion-selective 2D nanofluidic devices for osmotic energy harvesting.

Abstract ：
Flexible all-in-one electrochromic fabrics (AECF) have attracted attention for application in wearable intelligent electronics. However, undifferentiated and disordered ion transport within the AECFs usually cause a slow transfer kinetics of reactive ions and thus restrict their electrochromic performance. Here, a new strategy is proposed to optimize active ion transport based on a well-designed anion-selective ion conductor (ASIC) for boosting the anionic AECF. The ASIC is developed by the interaction difference between ions and electronegative functional groups in the fabric substrate. Benefiting from cation immobilization and free anion transport, the ASIC exhibits both high anion transference number (0.75) and ionic conductivity (2.41 x 10-3 S cm-1) at room temperature. Such optimization of anion transport dynamics enhances the efficiency of the electrochromic redox reaction in the polyaniline-based anionic AECF, contributing to a significant improvement of the overall electrochromic performance. Based on the switchable earth yellow and dark green discoloration, the AECF is further integrated into a camouflage uniform, achieving dynamic environment adaptation in deserts or forests. This work is anticipated to provide some fresh ideas for developing functional ion conductors of electrochromic fabrics toward applications in wearable intelligent electronics.

Abstract ：
Clay-based 2D nanofluidics present a promising avenue for osmotic energy harvesting due to their low cost and straightforward large-scale preparation. However, a comprehensive understanding of ion transport mechanisms, and horizontal and vertical transmission, remains incomplete. By employing a multiscale approach in combination of first-principles calculations and molecular dynamics simulations, the issue of how transmission directions impact on the clay-based 2D nanofluidics on osmotic energy conversion is addressed. It is indicated that the selective and rapid hopping transport of cations in clay-based 2D nanofluidics is facilitated by the electrostatic field within charged nanochannels. Furthermore, horizontally transported nanofluidics exhibited stronger ion fluxes, higher ion transport efficiencies, and lower transmembrane energy barriers compared to vertically transported ones. Therefore, adjusting the ion transport pathways between artificial seawater and river water resulted in an increase in osmotic power output from 2.8 to 5.3 W m-2, surpassing the commercial benchmark (5 W m-2). This work enhanced the understanding of ion transport pathways in clay-based 2D nanofluidics, advancing the practical applications of osmotic energy harvesting.

Abstract ：
Clay-based 2D nanofiltrations (NFs) have shown great potentials in wastewater treatment owing to their facile scale-up and low-cost feature. However, the swelling effect seriously limits their separation efficient towards the construction of high-performance NFs. Herein, an anti-swelling clay-based 2D NF is developed based on the strategy of electrostatic interlamellar fixation. The intercalation of positively-charged Fe(OH)(3) nanoparticles could effectively fix the interlayer spacing of negatively-charged montmorillonite-based 2D NF, contributing to a high dye (Congo red) retention rate up to 99.78 % and also a satisfactory flux of 60.65 L m(-2) h(-1) bar(-1). Separation mechanism was explored for the combined effects of size, electrostatic potential and conjugation on the retention rate. When scaling up (similar to 700 cm(2)), the anti-swelling 2D NF still maintain an excellent separation effect that is superior to almost all reported state-of-the-art 2D NFs. According to the detailed life cycle assessments (LCA), the advantages of MMT in the production process were demonstrated. The utilization of 2D clay material also exhibits superior resource, environmental and techno-economic benefits compared to other mainstream 2D materials. This work proposes an effective strategy to solve the swelling effect of clay-based 2D NFs towards the large-scale utilization of high-performance and low-cost separation membrane for efficient wastewater treatment.

Abstract ：
Achieving a high Li+ transference number is an effective strategy to inhibit the nucleation of lithium dendrites on the metal anode according to classical Sand's time principle. However, improving the Li+ transference number usually causes aloss of ionic conductivity of lithium metal batteries. Here, inspired by biological ion channels tuning ion transport, an electronegative nanochannels separator is developed to accelerate Li+ transport for enabling dendrite-free and high-rate lithium metal anodes. Benefiting from selective and fast Li+ transport, the electronegative nanochannels separator can simultaneously achieve high Li+ transference number (0.77) and high Li+ conductivity (1.36 mS cm(-2)) within a liquid lithium metal battery. Such an optimization of Li+ transport dynamics can significantly prolong the nucleation time of lithium dendrite and thus effectively suppress dendritic growth, which contributes to an extremely stable Li plating/stripping cycling for over 2000 h at a high current density of 5 mA cm(-2). When assembled into lithium metal batteries, the electronegative nanochannels separator enables superior comprehensive electrochemical performance compared with the commercial polyolefin one. This work provides new insights into the design of functional separators toward dendrite-free and high-rate liquid lithium metal batteries.

Abstract ：
Lithium dendrites are a major issue that restrict the commercialization of lithium metal batteries. It is well-accepted that lithium dendrite nucleation can be suppressed by improving the Li+ transference number based on the classical Sand's time principle. Here, a self-standing anionic metal-organic framework (MOF)-based functional separator with small pores is developed by simple doctor-blading to accelerate Li+ transport for an improved lithium metal anode. The design of this separator is based on the nano-confined channels of the MOF and negatively charged moieties (-SO3-) on the surface. Benefiting from the strong electrostatic interaction between the negatively charged nanochannels and ions within the liquid electrolyte, the anion transport is effectively suppressed, while the lithium-ion transmission is accelerated. Consequently, a high Li+ transference number of up to 0.85 is achieved within the liquid electrolyte, which enables ultra-stable Li plating/stripping on the lithium metal anode for over 4000 h at a high current density of 5 mA cm(-2). This work is expected to provide new insight into the development of dendrite-free and high-rate lithium metal batteries.

Abstract ：
Nanofluidics is promising in the construction of highly-efficient osmotic energy generator, but it is still a challenge to develop large-scale and high-performance nanofluidic membranes. The emerging covalent organic frameworks (COFs) provide a desirable platform to create nanofluidic membranes with high ion selectivity and permeability towards effective osmotic energy conversion. Herein, an ultrathin self-standing COF nanofluidic membranes based on terephthalaldehyde-tetrakis(4-aminophenyl)methane is developed to construct high-efficiency nanofluidic osmotic energy generator. Benefiting from the nano-confined channels (1.4 nm) and negative surface charges, the COF based nanofluidic membrane demonstrates both excellent cation selectivity and high ion conductance. Moreover, an ultrathin thickness of approximate to 1.5 mu m significantly reduces the membrane resistance. Consequently, the nanofluidic osmotic energy generator based on COF membrane can deliver a high output power of 5.31 W m(-2) under a 50-fold salinity gradient simulating natural river/sea junction, which is superior to most reported systems and reaches the industrial level. More importantly, such a COF nanofluidic membrane exhibits excellent stability in response to various environmental factors, including wide saline solution concentration, temperature and pH ranges. This work is anticipated to highlight the great potential of 1D COF nanofluidic membranes toward highly-efficient osmotic energy generators.

Abstract ：
The lithium dendrite issue is a major bottleneck that limits the utilization of lithium metal anodes in high-energy rechargeable batteries. From the perspective of the dendrite nucleation mechanism, this work develops a new type of cation-selective (CS) separator with anion immobilization behavior to boost the lithium metal anode. By taking advantage of the poly(vinylidene fluoride) matrix, a strong binding force with anions contributes to an excellent CS property of the separator, which is further confirmed by molecular dynamics simulations. The CS separator developed in this work presents a high lithium-ion transference number up to 0.81. Considering such a dramatically reduced transference number of anions, it can prolong the nucleation time of lithium dendrite and thus achieve a high-stable Li plating/stripping cycling for 1000 h at a high applied current density of 3 mA cm(-2). The Li metal stabilization function of the CS separator is further studied in detail through both in-situ and ex-situ observations of dendrites growth. When integrating into lithium metal batteries (LMBs), the CS separators also contribute to enhanced electrochemical performances including discharge capacity, rate capability, and cycling durability. This work is anticipated to provide considerable insight for the creative design of CS separators toward dendrite-free LMBs.

Abstract ：
In sensory neurons of mammals, some temperature-sensitive transient receptor potential (thermoTRP) ion channels open its pore for cations passing through by the activation of a high ambient temperature above the threshold. This thermal stimulus promotes the conversion from intracellular osmotic energy to the electrical signal, which inspires us to control energy output from nanochannel-based osmotic power harvesting systems. Here, temperature-gated 2D cationic nanochannels, stemming from the stacking of functionalized montmorillonite (MMT) lamellae, are constructed for controllable osmotic energy harvesting. Through electronegative modification, nanochannels demonstrate an excellent cation selectivity that is supported by both experimental and theoretical findings. When serving as a separator for osmotic power harvesting, cationic nanochannel membrane could deliver an output power of approximately 150 mW m(-2), which is envisaged to be boosted by reducing the membrane resistance. Based on the temperature-gated performance of nanochannels, the energy output form osmotic power harvesting system could be regulated by alternating temperature switches in a reversible and stable manner. The output power on the external load resistance is doubled under a mild temperature rise from 30 degrees C to 60 degrees C. The strategy that combines intelligent response with osmotic power harvesting anticipates wide potentials for controllable energy utilizations.
