Chemists grow nano menagerie

Researchers from Sandia National Laboratories have found a simple way to make tiny, complicated shapes from zinc oxide, including arrays of vertically-aligned rods, flat disks, and columns that resemble stacks of coins. The researchers grew the structures, which are similar to those found in biomaterials, by seeding a solution with zinc oxide nanoparticles. They were able to produce different shapes by changing the amount of citrate in the solution at different points during particle growth.
