Graphene Graphene Graphene is an allotrope (form) of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a semimetal with small overlap between the valence and the conduction bands (zero bandgap material).<ref name="10.1002/adma.201502544 p.6519-6525"></ref> It is the basic structural element of many other allotropes of carbon, such as graphite, diamond, charcoal, carbon nanotubes and fullerenes. Graphene has many uncommon properties. It is the strongest material ever tested, conducts heat and electricity efficiently, and is nearly transparent. Graphene shows a large and nonlinear diamagnetism, greater than that of graphite, and can be levitated by neodymium
The Mighty Atom (Thunderbirds) none of the regular characters. "The Mighty Atom" is the only episode of "Thunderbirds" to feature all of the regular characters and all of the "Thunderbirds" machines. It also marks the first appearance of "Thunderbird 4" in the series. The two-part version that was broadcast in some UK regions separates the older footage from the material that was filmed for the episode's expansion. Certain scenes were altered to create this format; these include one of a news conference in Melbourne, which was shortened, and another in which the Tracy brothers play a practical joke on Lady Penelope, which was removed
