Abstract

The shape of copper metal particles (see Figure) is demonstrated to depend on the structure of the mesophase (cylindrical reverse micelles, interconnected networks of surface aggregates or lamellar phases) i the surfactant system used as a microreactor for their synthesis. An understanding of this correlation is of great importance for magnetic recording technology
