Ultralow Loading Iridium Doped Hollandite Manganese Oxide Nanowires for Efficient Acidic Oxygen Evolution Reaction

Advanced Materials, EarlyView.
Ultralow iridium loading in hollandite MnO2 nanowires delivers an order of magnitude higher Ir mass activity than commercial IrOx for acidic water oxidation. Across pH and potential, Ir stays framework‐associated while Mn reconstructs, yet the most restructured catalyst is not the most dissolved, indicating that dissolution alone is an incomplete ...

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

Advanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Smart‐Release Ion‐Exchanged Ca‐Montmorillonite for Corrosion Protection of AA2024 Aluminium Alloy

Advanced Materials Interfaces, EarlyView.
Smart‐release anticorrosion pigments based on Zn‐ and Mn‐modified montmorillonite were developed by ion exchange of Ca‐montmorillonite and evaluated for the protection of AA2024 aluminium alloy in artificial acid rain. Both modified pigments provided effective corrosion inhibition, with Zn‐modified montmorillonite (Zn‐MMT) achieving an inhibition ...

Region‐Specific Profiling of the Gut Microbiome and Metabolite Landscape in Response to Dietary Intervention Using Electronics‐Free Ingestible Smart Sampling Capsules

Advanced Materials Technologies, EarlyView.
Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...
