Rhondite is a nano-scale helical carbon-based structure created by Robert Job that may be used in the production of steels and alloys to increase cohesion, strength, and uniformity. Each helix is actually made up of small spheres called buckyballs or fullerenes. Each fullerene sphere contains metallic atoms inside of the carbon cage; and as such have created a subset known as metallofullerenes. It is the chaining and winding of the metallofullerenes into their natural shapes that produces the unique Rhondidic structure.
