Amphiphilic Non‐Isocyanate Polyurethane Coatings With Tunable Antifouling and Fouling‐Release Performance: A Log‐Ratio Assessment Framework

Advanced Materials Interfaces, EarlyView.
Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.

Scalable Production of Disordered Nickel‐Iron‐Aluminum Oxides as Stable Anodes for Water Electrolysis: The Role of Aluminum

Advanced Materials Interfaces, EarlyView.
Solution precursor plasma spraying enables the scalable fabrication of porous and disordered nickel‐iron‐aluminum oxide coatings as precious‐metal‐free anodes. Aluminum inhibits crystal growth, optimizes local atomic sites, and enhances charge and ion transport to accelerate reaction kinetics, leading to excellent performance and operational stability.
