Initiated ignition at one end to trigger an alloying reaction.
Faster reaction kinetics were observed with sharper interfaces in the films.
The reaction speed was significantly influenced by the morphology of the Pt/Al films.

Abstract

Pt/Al Nanofoils In article number e01263, Heiko O. Jacobs and co-workers design a gas-phase electrodeposition process enabling local self-assembly of Pt and Al nanoparticles into linear bimetallic stacks. These films are ignited at one end, triggering a self-propagating alloying reaction. Reaction speed is shown to depend strongly on Pt/Al film morphology, with sharper interfaces yielding significantly faster kinetics.
