A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms. The molecule may be a hollow sphere, ellipsoid, tube, or many other shapes and sizes. Graphene (isolated atomic layers of graphite), which is a flat mesh of regular hexagonal rings, can … Web22 de jul. de 2024 · Fullerene molecules can be used for drug delivery into the body as lubricants as catalysts and in the form of carbon nanotubes can be used for reinforcing composite materials eg sports equipment like tennis rackets (see further down the page). They have many chemical synthetic and pharmaceutical applications.
