Renewable Spirocyclic High-Density Fuel Synthesis via Self-Sensitized [2 + 2] Photocycloaddition of β-Pinene and Methyl Cyclopentenone

Abstract Renewable high-energy-density fuels hold substantial promise for advancing sustainable aviation. However, realizing this potential requires the development of effective strategies for constructing high-performance fuel molecules. Herein, this study reports the synthesis...

Breaking single‐ion limits: Charge compensation enables concurrent Li/Br recovery and LiBr enrichment in produced water

Abstract Produced water from oil and gas fields contains Li + and Br − resources, but their low concentrations and complex coexisting ions make efficient recovery difficult. A charge‐compensated dual‐electrode system is developed for simultaneous Li + /Br − recovery and LiBr enri...

Electrochemically Enabled Self‐Intercalation for Symmetry Breaking and Metallic Ferroelectricity in Nb 1+x S 2

ABSTRACT Two‐dimensional (2D) metallic materials that simultaneously exhibit inversion symmetry breaking are highly desirable for nonlinear optics, unconventional ferroelectrics, and symmetry‐driven electronic functionalities, yet controllably inducing structural asymmetry withou...

Gradient‐Mass‐Transfer Synthesis of 2D [Bi 2 CuO 3 ]SO 4 Crystals for Anisotropy Engineering

ABSTRACT The intrinsic physical anisotropy of low‐symmetry materials makes them highly promising candidates for polarization‐sensitive devices. However, their practical application remains constrained by the scarcity of single materials that can combine low symmetry with high per...

Synergic Regulation of Active Site Electron Polarization and Interlayer Electron Coupling in COFs for Photocatalytic Hydrogen Peroxide Synthesis

ABSTRACT Covalent organic frameworks (COFs) are promising photocatalysts for the oxygen reduction reaction (ORR), yet reconciling the different electronic requirements in different elementary steps remains challenging. Herein, guided by the Sabatier principle and Marcus–Hush elec...

Toward In Situ ProgrammingLigand Desorption/AdsorptionDynamics of Metal Nanoparticles in Electrocatalysis

Abstract Ligand effects represent a long-last dilemma in metal nanocatalysis, as organic ligand coordination inevitably blocks active metal sites while maintaining structure stability of nanoparticles. To tackle this challenge, we demonstrate herein a supramolecular interaction-a...

Enhanced discrimination of 1‐octene over 2‐octene for high‐selectivity separation by bimetallic Ag + /Cu 2+ ionic liquid

Abstract The separation of 1‐octene from 2‐octene is a key bottleneck in the purification of Fischer–Tropsch (F–T) C8 α‐olefins because of their similar physicochemical properties and competitive metal–olefin complexation. To address the limited discrimination between terminal an...
