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
Inside the Atom did not have adequate science reading material. Inside the Atom Inside the Atom is a popular science book by American author Isaac Asimov. The first edition of the book was published in 1956 by Abelard-Schuman. Revised editions were brought out in subsequent years. The book describes the internal structure of the atom. The sequence of concepts described in the book follows the sequence that those facts were discovered in. It describes the various sub-atomic structures within the atom, and the functions they fill in the whole structure. Later chapters describe chemical elements and isotopes, the stability and instability of atomic
