Abstract

The scanning electron microscopy image (tilted, colored) shown on the inside cover depicts a ring of zinc oxide particles. This ring was obtained from a droplet of a highly diluted solution of zinc acetate by overheating on a 250°C hot silicon substrate, a method reported by Rainer Adelung and co-workers on p. 1262. The overheating creates an explosion, which results in a spray of microscale droplets that form many rings similar to the one shown over a macroscopic substrate surface.
