Advanced Functional Materials

ABSTRACT Additives and passivators are commonly used to regulate crystallization and suppress defects in halide perovskites. However, existing additives or passivation agents struggle to concurrently achieve effective defect passivation and efficient charge transport, and their passivation effects often fail to endure throughout device fabrication and operation. Here, we systematically screened a…

ABSTRACT Electrochromic devices offer a compelling platform for dynamic control of light and heat, with significant potential for energy‐efficient smart windows and adaptive optoelectronic applications. However, their widespread adoption is critically hindered by the lack of competent anodic materials capable of mitigating charge imbalance between the cathodic and anodic layers. Here, we demonstr…

ABSTRACT Na 4 Fe 3 (PO 4 ) 2 P 2 O 7 (NFPP) cathode material exhibits a robust structural stability, conferring long cycle life for sodium‐ion batteries. Nevertheless, the intrinsically low electronic and ionic conductivities of NFPP impede its widespread practical applications. Herein, a high‐throughput density functional theory screening paradigm coupled with experimental validation, was employ…

ABSTRACT Ferroelectric materials exhibit great potential for nonlinear optical applications due to their robust second‐order nonlinear optical responses. Strain engineering of such materials has demonstrated significant enhancement of second‐harmonic generation (SHG) responses. However, achieving order‐of‐magnitude amplification in bulk crystals and understanding anisotropic strain‐property relat…

ABSTRACT The integration of two‐dimensional (2D) MXene nanosheets into polyvinylidene fluoride (PVDF) matrices enables the design of multifunctional nanocomposites with enhanced properties. However, most attention has been dedicated to their electrical and dielectric characteristics, with information about the effect of MXene on mechanical properties being limited. This study systematically inves…

ABSTRACT Melanoma progression is sustained by profound metabolic rewiring and immune suppression within the tumor microenvironment, where adipocyte‐derived lipid droplets (LDs) serve as key metabolic regulators. Here, we exploit this intrinsic biology by engineering resveratrol‐loaded LDs (RSV‐LDs) as natural, lipophilic nanocarriers to drive intracellular delivery and immunometabolic reprogrammi…

ABSTRACT Solid polymer electrolytes (SPEs) hold great promise for advancing next‐generation lithium (Li) metal batteries owing to their facile processability and compositional flexibility. However, their practical applications are severely hindered by the low concentration of movable Li + and poor interfacial stability. Herein, a polarization‐induced effect potentiated in situ polymerized poly(1,…

ABSTRACT Amorphous metal nanomaterials (AMNs) are highly coveted catalysts due to their long‐range disordered atomic arrangements and abundant coordinatively unsaturated sites. However, their practical implementation is severely hindered by their inherent thermodynamic drive toward crystallization. Here, we report a DNA condensates‐directed kinetic trapping strategy to construct a new class of hy…

ABSTRACT Although ultrathin lithium on copper foils addresses the issue of dendrite‐induced poor electron transport, their practical application is fundamentally limited by the excessive mass of inactive copper, which severely degrades the energy density of lithium metal batteries. To overcome this trade‐off, we developed an ultralight conductive mesh by modulating a highly conductive MXene layer…

ABSTRACT Designing cost‐effective and durable catalysts for the urea oxidation reaction (UOR) at industrial current density is key to materializing UOR‐assisted water electrolysis for green hydrogen production while remedying environmental urea pollution. Here, we discovered the morphology‐dependent in situ reconstruction to transform copper‐based two‐dimensional nanosheets and zero‐dimensional c…

ABSTRACT Many scientists would have no doubt that water droplets tend to be firmly adhered to hydrophilic surfaces. Contrary to this common belief, we have succeeded in preparing surfaces that are statically very hydrophilic but exhibit surprising water slipping performance. These surfaces were prepared through a chemisorption of ethoxy‐terminated polyethylene glycol (PEG) organosilane (Si‐PEG‐Si…

ABSTRACT The development of lightweight heterogeneous systems capable of efficient electromagnetic wave absorption in the low‐frequency range (2–8 GHz) remains a significant challenge. Herein, a series of graphite/graphitic carbon nitride (g‐C 3 N 4 ) composites were fabricated via co‐ball‐milling of graphite and melamine followed by heat treatment. Co‐ball‐milling is found to facilitate particle…

ABSTRACT Developing fiber actuators with both complex deformability and precise programmability remains a critical challenge in smart textiles and soft robotics. Inspired by the segmented structure of earthworms, we actively guide the Plateau−Rayleigh instability to fabricate microfibers with a segmented core in a sodium alginate (SA)/polydimethylsiloxane (PDMS) shell‐core structure. The off‐cent…

ABSTRACT The functional properties of metal‐organic framework (MOF) thin films crucially depend on their structure, which is often difficult to determine. A widely investigated material is Cu(bdc) (bdc = benzene‐1,4‐dicarboxylic acid) grown from solution, for which various thin‐film structures have been suggested. Unfortunately, none of them represents a (meta)stable polymorph and is simultaneous…

ABSTRACT Constructing stable, molecularly defined active interfaces on cost‐effective oxide supports is a pivotal yet unmet challenge in oxygen evolution reaction (OER) electrocatalysis, as conventional sacrificial or indirect strategies preclude direct control over the functional interface where catalysis unfolds. Herein, we demonstrate this concept on spinel iron oxide, achieving a robust Fe‐(O…

ABSTRACT Polyimide (PI) is recognized as a high‐performance biomaterial membrane due to its high mechanical strength, excellent biocompatibility, biological stability, and highly tunable chemical structure. However, the intrinsic hydrophobicity of PI blood fluid contact ultrafiltration (UF) membrane materials poses risks related to separation efficiency and stability, as well as complications ari…

ABSTRACT Membrane fouling remains a major limitation for the long‐term operation of pressure‐driven separation processes. Although piezoelectric membranes provide a promising route for self‐powered antifouling, it is still challenging to fabricate porous membranes that combine high permeability with high electroactive β‐phase content through scalable processes. Here, we report a dual‐side synergi…
