Hypothesis With varied affinities for distinct liquids, liquid/solid interfaces can exhibit different stability against external liquids. For liquid-infused Janus membranes with different surface chemistry, there may be significant osmotic pressure gradients across the membrane, facilitating liquid gating of various liquids in diverse systems. Such strategy may highly widen the application areas of liquid gating technology. Experiments Liquid-infused Janus membranes were prepared via the combination of hydroxyapatite (amphiphilic but more water-loving) on one side and 3-(dodecylamino) propane-1-sulfonic acid (amphiphilic but more oil-loving) on the other side and subsequent infusion of various liquids (water or oils). The gating property of them was studied for all the conditions and the application potential in various areas including medical and micro-reaction was also explored. Findings After being infused with certain liquids (i.e., water or oils), the obtained membranes displaying opposite affinity toward water and oils can universally gate immiscible liquids at a high rectification ratio in air and in liquids. The interfacial instability of liquid films on the reverse sides was found to be critical in the achievement of liquid gating. Moreover, such gating property is also applicable in the transportation of various soluble substances (ions and drugs) and facilitating the dislodgement of blood.

Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP)-based all-solid-state lithium battery (ASSLB) assembled with Ni-rich layered cathode (NCM), of much interest because of its high energy–density and safety, presents many challenges, one of which is poor interfacial instability resulting in large interfacial resistance. Nevertheless, the mechanism of electrochemical side reactions on the interfacial deterioration hasn’t been much investigated specifically, despite their close relationships in electrochemical performance. Herein, we report that the fundamental origin of interfacial chemical reactions is the migration of Ni 2+ from the nickel-rich cathodes to the NCM/LATP interface, for the first time, and the simultaneous chemical reaction with Ti 4+ in LATP, followed by the decomposition of LATP. In view of this, an elaborately designed regulation strategy, in-situ construction of the layered perovskite La 4 NiLiO 8 buffer layer , is proposed to effectively reduce the content of Ni 2+ on the surface of the nickel-rich cathodes and alleviate the chemical reaction between Ni 2+ and Ti 4+ , thereby improving the interfacial stability between NCM and LATP. As a result, the assembled ASSLBs with the La 4 NiLiO 8 buffer layer exhibit high initial discharge capacity (171.49 mAh/g) and excellent cycling performance with 89.47 % capacity retention after 100 cycles at 0.1C.

Three-dimensional (3D) superlattice materials self-assembled from functional inorganic nanoparticles (NPs) have attracted extensive attention due to the unique properties of the building blocks and additional intriguing collective properties derived from the interaction between adjacent NPs. However, the spontaneous assembly of inorganic NPs into 3D free-standing plasmonic superlattices still remains an enormous challenge. Herein, we report a facile and universal strategy to assemble gold nanoparticles (AuNPs) tethered with polystyrene (PS) and poly(2-vinylpyridine) (P2VP) homopolymers into 3D free-standing sheet-like superlattices by systematically tuning the oil/water interfacial tension and the interfacial instability of emulsion droplets. The prepared sheet-like superlattices are multilayer and the AuNP building blocks stack as tetrahedra, in which each AuNP building block is partially sitting on the three other nearby nanoparticles. Moreover, the interparticle distance between adjacent NPs can be effectively regulated by varying the molecular weight of the tethered PS ligands on the surface of AuNPs. This template-free approach provides a novel and effective route to manipulate nanoparticles into free-standing ordered 3D superlattices with a wide range of potential applications.

Devices based on 2DMs van der Waals (vdW) heterostructures always compose of multiple contacts. Due to the instability of nanoscale 2DMs and interfaces, these contacts can be affected by the operation-induced photo or thermal effect. They can trigger the evolution of junctions and rearrange the junctions across a device, which are detrimental for applications. Herein, vdW heterostructure of indium selenide (InSe) and black phosphorus (BP) on Au electrodes are investigated to reveal the contact evolution and its relation to device performance. During operation, light irradiation changes the I–V characteristics from symmetry to strong rectification. Photocurrent mapping and Kelvin-probe force microscopy (KPFM) reveal triple junctions in this heterostructure, i.e., Au-InSe junction, InSe homojunction, and InSe-BP heterojunction. The variation of I–V characteristics of vdW heterostructure is ascribed to the evolution of Au-InSe junction from quasi-ohmic junction with a near-zero work function difference ( Δφ ) to a strong Schottky junction ( Δφ = ≈0.27 eV). The stabilized device demonstrates distinguished time-domain response at individual junctions and overall device, indicating the evolution of contacts and the consequent opposite junction directions degrade the overall device performance. This research emphasizes the importance of dealing with heterogeneous contacts and junction directions in designing vdW heterostructure photodetectors.

In this work, we proposed an effective route, i.e., three-dimensional (3D) confined co-assembly of block copolymers (BCPs) and inorganic nanoparticles (NPs) within organic emulsion droplets, to efficiently encapsulate high-density and large-size NPs into the wall of BCP vesicles. Attributed to the interfacial instability, the aqueous phase could spontaneously enter into the organic emulsion droplets, thus inducing the formation of BCP vesicles encapsulated with NPs. Moreover, it is found that the encapsulation of NPs into the vesicle wall is mainly dominated by the ratio (DN/dw0) of the NP diameter (DN) to the layer thickness of the affinitive blocks (dw0). Utilizing the 3D confined co-assembly of polystyrene-block-poly(4-vinylpyridine) and PS-coated gold nanoparticles (AuNPs) with different diameters, the high-efficiency encapsulation of AuNPs in the BCP vesicle wall at a DN/dw0 value of 0.66 can be achieved, which is greater than the previous reported critical value (i.e., DN/dw0 ≈ 0.5). Although the conformational entropy loss of the polymer chains increases with the introduction of AuNPs, the NPs can still be successfully encapsulated into the vesicle wall because the oil–water interface can suppress the diffusion of NPs to the aqueous phase. However, as the DN/dw0 value is further increased to 1.04, AuNPs will be repelled out of the vesicles because of the extremely strong entropic repulsion arising from the drastic loss in conformational entropy of PS blocks, thus forming some spherical hybrid micelles independently. Our results provide a new and facile route to realize the efficient encapsulation of large size NPs into polymeric vesicles.

Hybrid heterostructure materials have received considerable attention due to the integration of each component and abundant functional applications in micromotors, catalysis, photothermal therapy, drug delivery, and bioimaging. However, the preparation of organic/inorganic heterostructure nanoparticles (HSNPs) with high quality still remains a remarkable challenge since thermodynamically metastable structures usually coexist, resulting in a lack of organic scaffolds with extreme uniformity both in shape and size distribution. Here, we prepared polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer (BCP) core–shell spherical colloids driven by interfacial instability of soft and deformable emulsion droplets. Ultra-low interfacial tension was achieved through the co-adsorption of BCP segments and sodium dodecyl sulfate (SDS) surfactant, which had a strong affinity with the P4VP segment at the interface of the emulsified droplets. The excellent and homogeneous BCP colloids were further utilized as organic scaffolds to selectively grow a functional SiO2 layer on the surface of the BCP spherical colloids, producing BCP/SiO2 HSNPs with highly uniform shape and size distribution originating from the PS-b-P4VP scaffolds, thus providing an efficient and general strategy to construct and design organic/inorganic HSNPs with diverse applications.

High-throughput production of monodisperse microdroplets has revolutionized many fields, typically relying on shear-induced emulsification in intricate microfluidic channels to induce the Rayleigh-Plateau instability. This mechanism exhibits low robustness due to its high dependence on the physical properties and flow conditions of fluids. Here, we report a robust emulsification mechanism—wetting-induced interfacial instability—for droplet emission. We find that, when pendant microdroplets in the air contact with an immiscible wetting bulk phase, it triggers interfacial instability in the hanging droplets and then their rapid breakup into the bulk phase. This simplifies the monodisperse microdroplet production using a nozzle positioned above an air-liquid interface, requiring no complex microchannels. We demonstrate that this method exhibits highly scalable production and exceptional robustness against variations in physical properties and flow conditions of fluids, including highly viscous non-Newtonian fluid (56,600 millipascal-seconds). This mechanism provides a simpler alternative to the traditional Rayleigh-Plateau instability for emulsification, offering opportunities for industrial applications and insights into microscale interfacial science.

The unstable and fragile solid electrolyte interphase (SEI) has restricted the application of Na metal anodes. Despite numerous research efforts being put into understanding its chemical composition and physical properties, direct observation of its formation remains a challenge due to the lack of temporal and spatial resolution. Here, through combined in situ probing techniques, we exhibit two pivotal stages associated with SEI instability during the often-neglected formation process. It is revealed that Na metal that is not uniformly passivated at the initial (passivating) stage will trigger unrestricted electrolyte decomposition and homogeneous components distribution during the subsequent (growing) stage. SEI with homogenously distributed components is found to have higher solubility than that with a layered structure evolved from a compact passivation layer. Through demonstrating an SEI dissolution model that is closely related to its formation process and compositional distribution, this work sheds light on an uncharted territory of Na metal batteries.

Solid-state sodium metal batteries have attracted great interest because of their improved safety and abundant Na resources. However, the interfacial resistances and instabilities induced by parasitic reactions, together with Na dendrite issues, result in reduced rate capability and poor cycling stability. Here, we address these challenges by intrinsically inhibiting parasitic interfacial redox reactions through enhanced P-O covalency in Na 3 Zr 2 Si 2 PO 12 (NZSP) with Na 2 SiF 6 incorporation, wherein the high electronegativity of F strengthens P-O covalency. Additionally, SnF 2 coating provides a sodiophilic surface and stabilizes the NZSP interface, which is essential for effective electrochemical cycling. This integrated approach significantly reduces interfacial impedance to 2.0 Ω cm 2 , enabling stable Na plating/stripping for 3600 hours at 0.5 mA cm -2 /0.25 mAh cm -2 . The full cell with Na 3 V 2 (PO 4 ) 3 positive electrode demonstrates stable cycling with high-rate capability (87.5% capacity retention after 2500 cycles at 1 C and 96.1% capacity retention after 1200 cycles at 5 C). This study sheds light on the development of high-performance quasi-solid-state sodium batteries.

Lithium argyrodites electrolyte with high ionic conductivity and relatively lower cost show great potential as candidates for solid-state batteries. Further improvement of their conductivities can accelerate their applications. One of the means to significantly promote the conductivity of Li-ion is dual doping. Herein, Ag/Br dual-doping strategy is applied on Li 6 PS 5 Br (2.76 mS cm −1 ) to boast its conductivity to 6.15 mS cm −1 for Li 5.55 Ag 0.05 PS 4.6 Br 1.4 . The structural variations and chemical/electrochemical stability of the obtained electrolyte are carefully investigated. Li 3 InCl 6 electrolyte is introduced in the new battery configuration to mitigate the interfacial instability with LiNi 0.6 Mn 0.2 Co 0.2 O 2 active material enabling good electrochemical performances . The assembled battery delivers a discharge capacity of 160.8 mAh g −1 for the 1st cycle and maintains 85.9% of the initial value after 50 cycles at 0.5C. This modification strategy was proved effective for increasing the conductivity of sulfide electrolytes in this work.

Layered lithium-rich oxides(LRO) materials have garnered significant attention due to their high reversible capacity and broad operating voltage range. However, the practical application of LRO materials is still restricted by the serious interfacial instability and surface structure reconstruction during long-term cyclic test. In this study, we use 2-(Trimethoxysilyl)ethyl methacrylate (TSM) as a multifunctional electrolyte additive to enhance the electrochemical performance of the Li/LRO cell. The capacity retention of the Li/LRO cell improves significantly from 67.2 % to 85.8 % after 100 cycles at 0.5C (1C = 300 mAh g -1 ) between 2.0 and 4.8 V with the addition of 2 % TSM. Under harsh conditions (with the addition of 1000 ppm H 2 O to the electrolytes), Li/LRO cell with TSM additives maintains the capacity retention of 82.5 % after 100 cycles, which is significantly higher than the cell without additives (38.0 %). Both theoretical calculations and experiments results demonstrate that TSM exhibits higher oxidation activity than the solvents, forming a uniform cathode electrolyte interphase (CEI) on the LRO surface. The TSM-derived CEI layer effectively mitigates the interfacial parasitic reactions and prevents structural degradation of LRO. Furthermore, theoretical calculations and nuclear magnetic resonance (NMR) results confirm that TSM effectively eliminates water (H 2 O) and hydrofluoric acid (HF), mitigating their adverse effects.

The chromium-free oxide precursor strategy effectively avoids chromium volatilization and electrode contamination in metal-supported solid oxide fuel cells (MS-SOFCs), while enabling high-temperature co-sintering in air to simplify the fabrication process. However, the drastic microstructural coarsening, dimensional shrinkage, and thermal expansion mismatch with adjacent components of such substrates during high-temperature sintering, reduction, and thermal cycling collectively contribute to the interfacial instability and structural degradation of MS-SOFCs. Herein, we address these issues by incorporating a small amount of Gd0.1Ce0.9O1.95(GDC) to the NiO-Fe2O3(NFO) substrate. The incorporation of GDC significantly enhances the sintering compatibility and reduction stability of the MS-SOFCs, alleviating the stress-induced warping and distortion. Moreover, the GDC phase has a pinning effect to suppressing the coarsening of the substrates during high-temperature sintering and reduction processes, enhancing mechanical integrity and structural robustness of the single cell. With 15 wt% GDC incorporated into the NiFe substrate, the corresponding MS-SOFC with GDC electrolyte film achieves a peak power density of 0.56 W cm−2at 600 °C, along with markedly improved structural integrity and operational reliability. This work demonstrates a viable pathway for designing heterophase-engineered supports with matched thermomechanical properties, offering promising prospects for enhancing the durability of MS-SOFCs.
