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

ABSTRACT In situ detection of proteases has been extensively exploited for diverse biomedical applications; however, spatially controlled amplified imaging of extracellular proteases at diseased sites remains a significant challenge. Here, we report the design of DNA‐peptide‐PNA...

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...

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...

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...
