Fullerenes and graphemes

• What is the structure of graphene?

  Graphene is a single layer of graphite, only one atom thick.
• Why is graphene a good conductor of electricity?

  Graphene has delocalized electrons that can move and carry electrical charge.
• How might graphene be useful in electronics?

  Graphene's ability to conduct electricity makes it useful for electronic components.
• What contributes to graphene's high melting and boiling points?

  Graphene has a large number of strong covalent bonds that require a lot of energy to break.
• What are the basic structural features of fullerene molecules?

  Fullerenes have hollow shapes, usually with hexagonal rings of carbon atoms.
• What is the first fullerene molecule to be discovered?

  The first fullerene molecule discovered is called buckminsterfullerene.
• How many carbon atoms are in buckminsterfullerene?

  Buckminsterfullerene contains 60 carbon atoms.
• What are some uses of fullerenes?

  Fullerenes can deliver drugs, act as lubricants, and serve as catalysts.
• What are carbon nanotubes?

  Carbon nanotubes are fullerenes shaped into long cylinders with a small diameter.
• What is a notable property of carbon nanotubes related to their structure?

  Carbon nanotubes have a very high length to diameter ratio.
• What are the tensile strength properties of carbon nanotubes?

  Carbon nanotubes have a high tensile strength, allowing them to withstand significant stretching force.
• Why are carbon nanotubes good conductors of electricity and heat?

  Carbon nanotubes have delocalized electrons that facilitate conduction of electricity and heat.
