Abstract

original image

Intelligent design? Depending on the starting pH, ultralong nanofibers (see picture; left) or patterns of concentric circles (right) are produced in the polymer-controlled crystallization of BaCO3. The ring patterns are the first examples of nanoparticle self-organization that can be described by a Belousov–Zhabotinsky formalism.
