A Comparison of 2 Different Oxidation Results in Nickel-Cobalt Nanoparticles

Caption

A comparison of two different oxidation results in nickel-cobalt nanoparticles. While a small percentage of the particles form hollow spheres (top), the vast majority form a porous Swiss-cheese-like structure (bottom) that has much greater surface area for the same volume.
