Here's a "forest on a finger." Carbon nanotubes are engineered at the atomic level into cylindrical structures made of carbon (similar to those found in graphite, the material in No. 2 pencils). The nano-sized arrangement gives them unusual and useful properties for industrial applications. These types of nanotubes could appear in your TV, laptop, or cell phone someday. Some nanotubes are already used to strengthen sailboats, tennis rackets, and bicycles. (A. John Hart, University of Michigan)[back]
