Large‐Scale, Homogeneous Solution Crystallization of 2D Covalent Organic Frameworks with Integrated Crystallinity and Solubility for Ultrafast Noble Metal Recovery

ABSTRACT Solution‐processable covalent organic frameworks (COFs) are crucial for advancing practical applications, yet traditional top‐down exfoliation into solvophilic nanosheets suffers from low efficiency and limited scalability. This study presents a large‐scale homogeneous c...

A Transferable Descriptor for Accurate Prediction of Excitonic Couplings in A-D-A Organic Photovoltaic Acceptors

Abstract Exciton diffusion length (LD) is a key parameter determining the power conversion efficiency of organic solar cells (OSCs), yet its fast and accurate calculation is computationally challenging due to thin-film structural disorder and the long-range nature of excitonic co...

Antibody-Mimicking Nanocluster Ameliorates Osteoporosis in Preclinical Model

Abstract Osteoporosis occurs due to the synergistic effect of increased bone resorption and decreased bone formation. However, a therapeutic approach that can simultaneously inhibit osteoclastic resorption and promote osteogenic activity directly is still lacking. Growing evidenc...

Domain-Wall-Mediated Ultralow-Barrier Sliding and Pinning in Ferroelectric Moire Superlattices Revealed by Machine Learning

Abstract Sliding ferroelectrics built from stacked nonpolar monolayers enable out-of-plane polarization and unconventional switching via interlayer sliding, yet the microscopic sliding dynamics remain unclear. Using machine-learning molecular dynamics, we reveal spontaneous, ther...

Over 20% Efficiency in As–Cast Organic Solar Cells Enabled by Flory–Huggins Parameter Engineering

ABSTRACT The realization of high–efficiency as–cast organic solar cells (OSCs) represents a key step toward simplified processing and scalable fabrication for commercialization. However, achieving high–performance as–cast devices remains challenging because it demands delicate ba...

Discovery and Manipulation of a Single Polaron in a Monolayer Mott Insulator

Abstract Polarons are quasiparticles composed of excess electrons and local lattice distortions that are crucial for understanding many-body physics. However, atomic-scale observation and manipulation of an intrinsic polaron in strongly correlated systems still remain elusive. He...

A narrowband bandpass filter with multiple transmission zeros based on parallel coupled lines structure

Purpose This paper aims to present the theoretical design of a narrowband bandpass filter (BPF) using a multiple parallel-coupled line structure. The proposed filter delivers robust narrowband performance, generates multiple transmission zeros (TZs) and achieves wide-stopband rej...

Differential Coupling of Nanoparticle Translational and Rotational Diffusion to Polymer Relaxation Modes in Unentangled Polymer Melts

Abstract The diffusion of spherical nanoparticles (NPs) in unentangled polymer melts is investigated using coarse-grained molecular dynamics simulations. We show that for both translational and rotational diffusion, when the NP diameter d is smaller than a characteristic length l...

Nano-wrinkle waveguides for programmable polariton channeling

Abstract The intrinsic planarity of two-dimensional (2D) van der Waals (vdW) polaritonic media inherently limits the lateral confinement of vdW polaritons. Here, we transcend this geometric limit by introducing a deterministic strategy to engineer non-planar nano-wrinkle waveguid...

Windmill‐Type π ‐Extension Within Donor Moiety of Covalent Organic Framework Boosts Overall Photocatalytic Hydrogen Peroxide Production

ABSTRACT Covalent organic framework (COF)‐based catalysts are promising for overall photocatalytic hydrogen peroxide (H 2 O 2 ) production, yet the sluggish kinetics of water oxidation reaction (WOR) and inefficient charge carrier processes limit the catalytic performance. Herein...

Scavenger Receptor Class B Type 1 Mediated Transport Enables Delivery Across Capillarized Liver Sinusoids in Metabolic Dysfunction-Associated Steatohepatitis

Abstract Liver fibrosis in metabolic dysfunction associated steatohepatitis (MASH) lacks effective therapies, in part because therapeutic agents poorly penetrate the capillarized sinusoidal endothelium. As fibrosis progresses, liver sinusoidal endothelial cells (LSECs) become def...

Efficient Acidic CO 2 Reduction via Local Strain Engineering of Nickel Single‐Atom Catalysts

ABSTRACT Acidic CO 2 reduction reaction (CO 2 RR) enhances carbon efficiency and electrolyzer stability. Although nickel single‐atom catalysts (Ni‐SACs) effectively convert CO 2 into CO in neutral/alkaline conditions, their performance in acid is hindered by the competing hydroge...

Spatially Controlled Imaging of Proteases in Acidic Extracellular Milieu of Lesions Using DNA‐Peptide‐PNA Hybrid Probes

Collective FluidCoupling in Ultrathin Covalent OrganicFramework Membranes for High-Performance Electrokinetic Energy Harvesting

Abstract Nanofluidic membranes hold promise for hydroelectric energy harvesting, but their output power is often limited by high fluidic impedance. Here, we fabricate ultrathin covalent organic framework (COF) membranes with AA-stacked, regular nanopore arrays. These membranes ex...

Structural Water‐Enabled Helicity Emergence From an Asymmetric Achiral Molecule

ABSTRACT Helical supramolecular architectures are ubiquitous in nature yet remain challenging to construct from asymmetric achiral molecules. Here, we demonstrate that structural water acts as a symmetry‐breaking and frustration‐generating element in artificial self‐assembly. Usi...

In situ Second-HarmonicGeneration Probing of Magnetic-Field-InducedChiral Stacking in a Radical-Doped Liquid Crystal Monolayer

Abstract Functional open-shell π-radicals offer attractive optical and magnetic tunability but suffer from poor ambient stability, limiting their deployment in condensed-phase architectures. Here we circumvent this limitation by embedding the photolabile radical precursor HTTM-PD...
