Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

Advanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

Vertical vs. Adiabatic Ionization Energies in Solution and Gas-Phase: Probing Ionization-Induced Reorganization in Conformationally-Mobile Bichromophoric Actuators Using Photoelectron Spectroscopy, Electrochemistry and Theory [PDF]

, 2018
Ionization-induced structural and conformational reorganization in various π-stacked dimers and covalently linked bichromophores is relevant to many processes in biological systems and functional materials. In this work, we examine the role of structural,

Interfacial and Crystallographic Regulation of Zinc Anode via Electric Double Layer Reconstruction for Highly Stable Zn Anode

Advanced Functional Materials, EarlyView.
Trace amounts of perfluoro‐1‐butanesulfonyl fluoride enables the regulation of the Zn/electrolyte interface by the generated zincophilic ─SO3H groups with long hydrophobic ─CF2 tails, which adsorb strongly onto the Zn surface, displace water molecules from the inner Helmholtz plane, and reconstruct the electrical double‐layer structure.

Complexation‐Mediated Diffusion‐Limited Crystal Growth: A General Framework for Anisotropic Crystal Growth in Cu‐Based Perovskites

Advanced Functional Materials, EarlyView.
A Complexation‐Mediated Diffusion‐Limited Growth (CMDLG) framework is established to rationalize the anisotropic growth of lead‐free perovskites. Integrating coordination chemistry with mass transport kinetics, this study theoretically derives and experimentally validates that stable iodocuprate complexes induce a diffusion‐limited regime.

Fabrication of Pyridinic Nitrogen‐Functionalized Carbon Cloth for High‐Performance Iron‐Chromium Flow Batteries

Advanced Functional Materials, EarlyView.
The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.
