Interface‐Driven Control of Vanadium Carbide Micro‐ and Nanocrystal Growth During Chemical Vapor Deposition

Advanced Materials Interfaces, EarlyView.
A wrapped copper–vanadium interface enables reliable chemical vapor deposition growth of vanadium carbide micro‐ and nanocrystals. Adjusting methane supply shifts the process from the formation of many small crystals toward lateral expansion and merging of larger domains, while longer growth increases surface coverage without changing the cubic ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
