Abstract
The cover image shows a schematic view of the long-lasting oscillations observed during the electro-oxidation of formic acid on PtSn ordered intermetallic phases. Within the long road perspective that remits to infinity, oscillations on PtSn are very stable when compared to that on platinum. The higher stability of the oscillations on ordered PtSn surfaces is caused by its tolerance towards surface poisoning, which prevents surface deactivation and slows down the natural drift of the system. This is presented on p. 1753 by H. Varela et al.
