Engineering MnNiPx Cathode via Dual Role of Mn: Simultaneous Enhancement of Activity and Intermittent Operation Durability

Advanced Functional Materials, EarlyView.
Engineering MnNiPx cathodes through the dual role of Mn simultaneously improves hydrogen evolution reaction activity and intermittent‐operation durability. Mn preferentially oxidizes to protect Ni–P sites from irreversible oxidation, while metallic Mn incorporation enhances the HER kinetics of Ni–P active layer.

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

Advanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Adaptable Covalent Organic Framework‐Hydrogel Microneedles for Glucose‐Responsive Isoliquiritigenin Delivery in Diabetic Wound Therapy

Advanced Healthcare Materials, EarlyView.
We develop a covalent organic framework‐loaded Traditional Chinese Medicine monomer nanodrug delivery system (ISL@bCOF) via boron‐oxygen bonds, a smart response to glucose for delivering AI‐driven isoliquiritigenin (ISL) targeting ZBP1. This dynamic release mechanism, combined with transdermal delivery technology via potent microneedles, can modulate ...
