Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Advanced Materials, EarlyView.The miscibility of foreign elements in rutile‐type IrO2 and SnO2 is greatly enhanced under high Laplace pressure, where their crystal size is reduced to the nanoscale. This enhancement leads to the successful synthesis of DSA‐composition solid‐solution nanocatalysts with notable durability during the acidic OER in water electrolysis.
